Diamond tools inside the application should pay attention to?

1. before having a new Dresser, exit in the last finished feed. Many quality crisp diamond dressing tools, talking to the wheel in the beginning, can be easily damaged.
2. tilt angle 10-15 ° diamond dressing tools installed so that it points to the direction of rotation of the wheel.
3. firmly mounted dresser or clamping the trimming tools, tool head pendant shall not too much time.
4. in may cases, to work with cooling liquid. Entire repair time, and emery wheel experience of the coolant pour dressing tools.
5. the dressing in the beginning of, starting from the best point from the wheel, usually to the core wheel.
6. takes note of minor addition of. Maximum depth of subject, for coarse adjustment, inter alia: 0.001-0.002 inches. For intensive subject: 0.0005 to 0.001 inch.
7. Select the appropriate lateral movement according to the relevant manual. Horizontal moving slower (on a allow scale), use of lower the outer lining roughness in emery wheel.
8. should be inside the specified time interval on the dressing of emery wheel to avoid wheel blunt, the grinding force increases.
9. from the specified time interval, knife clip trimming tool, rotate the one-eighth ring, to help keep the dressing tools will almost always be sharp.
10. When diamond Dresser blunt or tools or clearly in peacetime, needs to be adjusted and replaced promptly.
11. In line with the diameter measurements the grinding wheel, diamond CARAT weight selection (content of pure diamond), larger diameter of emery wheel, select larger diamond CARAT value.
Attention
1. Whenever you place the first holder of diamond dressing tools, careful never to hit the outer lining of emery wheel.
2. no point diamond dressing wheel Center vertically alignment tools head, normally tilt of 10-15 °.
3. heat dressing tools to never be "quenched" (meaning sudden cold). In the event the dry dressing, must maintain the two trimming interval of their time, enough to create the fever of dressing tools cooling.
4. cannot assume that the wheel contains the ideal flat on the surface. When you start trimming, obtain the location in the highest point in the wheel, trim.
5. If at all, every wheel repair also, no greater than 0.001 inches within the radius in the wheel. Addition of huge amount could cause premature wear of diamond dressing tools and infrequently broken.
6. and not every addition towards allowance is just too small. For old or poor rigidity can not be officially used on a unit tool emery wheel dressing.
7. awareness of trimming cannot stay in one place a long time time. This will make the symptoms polishing wheel, producing high temperatures and damage the diamond dressing tools. Rotating dressing tool at least one time each day.
8. not being depreciation or damage the trim tool. Is always to adjust or replace it.
9. the lack rough trimming would be to select an overhaul along with mass and transverse feed rate too quickly, after which select when finishing trim repairs along with volume and slow Traverse feed rate. This may quickly damage diamonds dressing tools. If possible, it is suggested that after rough finishing and fine finishing, simply select the same transverse feed rate.

Diamond tools tips on how to improve

Diamond cutters include the most frequent sorts of cutting tools, basically with the matrix and diamond tool consisting of two parts, really easy, many manufacturers will work regarding how to improve the Diamond cutter. Compressor of the very lots of applications, a compressor is normally consisting of hundreds or 1000s of components, complex manufacturing process, technical requirements. So that you can match the production needs of the numerous parts, tooling and fixture is very important to reasonably designed with, in order to meet certain requirements of good, fast, and has to be improved and also on several diamond cutting tools and tooling design. Give three examples below:
Improvement, straight shank end milling cutter
2Cr13 chromium steel material in the packed Chamber, face width 12mm, dark 20mm, 200mm diameter ring groove. Initially using §? made 12 straight shank end mills for broadband steel processing, deep 5mm, processing and adhesion of diamond chip is below 5 minutes within the milling cutters, deteriorating cutting, milling cutter edge collapse, tool change frequently in the process, efficiency is incredibly low, machining a diamond ring groove to 150 minutes. Use after Japan's Mitsubishi diamond carbide milling cutter, although the performance is superior to for the former, but chip chip-stacking capacity there is tank problem, when automatic processing at the processing center, edge collapse, and even the tool appears broken.
Saw blades production utilizing the same cutter. Saw blade manufacturing process may be relatively backward, improved results over the years is tiny, no breakthroughs recently, after higher than a year of research and development because of the Eastern industrial automation limited, production of CNC gear drive devices, production pictures progress on saw blade technology, its device term for the saw blade automatic open CNC gear hobbing machine (CNC gear opened presses). Figure
Saw open effect of tooth-CNC turret punch press, high precision, small cuts better, equipment investment, high production efficiency, replace the automated mechanical punching machine, well suited for large batch line use. High penetration of automation, saving labor and improve yield.
Second, improvement of milling flange diamond tools
Spiral tooth clutch one-way shape to spiral end face structure, torsional moment of which passed itself off only when it's above a certain value, also referred to as safety clutch. Around the miller processing of the most extremely widely used technique is a technique for dividing head gear, calculated based on the lead change, configure the appropriate implementation of change between head and table piece uniform rotation and uniform motion, thus processing the Archimedes curved surfaces. Tool selection ф 8~ ф 10 State milling knife, on knife Shi necessary to Diamond milling knife cutting edged and workpiece axis phase cut, operation Shi tool fell to requirements depth Hou, min of handles insert min of Board hole within, shake min of handles 20 ring, in min of head rotating of while, table for longitudinal into to, makes workpiece for composite movement, are spiral slot; elevation tool, reverse turns min of head handles 20 ring, pull bolt, continues to shake min of handles 20 ring, insert bolt, and repeat above steps processing another a spiral slot.
These costly processing methods, and cannot be processed prior to drawings, stop at your tooth root Cutter radius. Need manual repair file root part keeps its R0.5, low efficiency, accuracy is just not guaranteed. This phenomenon, mcdougal after careful analysis, and using CAD-aided design, thought we would complete the initial tooling and tooling improvements. Theoretical calculation of diamond cutlery angles, shape, over, also has begun to consider shape, required is the place to processing tool.
On reflection, I personally use existing universal tool and Cutter Grinder for machining of workplace, ф 22 domestic broadband steel in spiral taper shank endmill with restructuring, front first grinding milling cutter, tyrannize tapered, single slope of 8 °. So grinding angle, enhances the chip capacity slot space, avoid more quick milling passes diamond chip stacking behavior occurs. As soon as the last operation was sharpening angle, angle is just too big small you can't start cutting pieces, therefore it is simple increase the risk for tool cutting edge break. Processing just for this tool, point after selecting 8 ° after ' quality 45# steel, try straight cutting effect is right, very smooth if the knife cuts deep 10MM.
Structure principle of three, tooling,
Its main part screw, right-handed helical teeth. Its working principle is always to turn hand wheel and drive the screw dextrorotation, helical gears for counter clockwise (based on the stress analysis of helical gear, levorotation, axial force f up), arrived a lead concurrently a week, simple structure and easy.
Tool after installation on milling machine spindle, vertical milling head turn clockwise to tug 7.5 °, level clamping tooling to milling machine working bench, where parts fit. After trying obtain the effect is shocking, the entire spiral flange process took only 5 minutes to accomplish, more cost-effective compared to original 5 times times, tool our life is the initial twice times, achieved once in most 200 grinding machining innovative, reuse tools approximately 10 times fully stick to the drawings and aspects of the standards. Ahead of that, spiral flange have try in three-axis machining vertical machining center with ball-end milling cutters (milling cutter machining helicoids interference), not really a longer processing time, and left the tool Nose Radius with the tooth root, governed by secondary processing.

Classification of diamond cutlery

Natural diamond (ND) tool
Vines for diamond peak, that's this characteristics:
(1) spike shows we have a diamond.
(2) the wave amplitude (FWHM) 4.1cm-1
Seems as a pure diamond. ND may be the hardest known mineral substances, mainly employed in the preparation of Cutter tool. Following your fine grinding of natural diamond cutter edge radius as high as 0.01~0.002μm. Natural single crystal diamond (Single Crystalline Diamond,SCD) technologically advanced part of the tool power 1500 times times but nevertheless towards the edge smooth. SCD turning of aluminum piston Ra can reach 4μm, and beneath same cutting conditions using PCD tool when machining the outer lining roughness of Ra for 15~50μm. SCD tool joined with precision and ultraprecision machining precision lathe, mirror surface can be obtained.
Polycrystalline diamond (PCD) tool
PCD adopted under conditions of heat and super high pressure cobalt gathered metal bond diamond powder sintered polycrystalline materials synthesis, also known as sintered diamond. Whole sintering of polycrystalline diamond tool cutter, milling, grain is often a random arrangement of PCD are isotropic, uniform hardness, graphitization temperature of 550 ° c. Tool with high hardness, high thermal conductivity, low thermal expansion coefficient, low coefficient of friction and high coefficient of elasticity. Blade is very sharp and so on.
Artificial polycrystalline diamond compact (PDC) tool
To reinforce PCD blade toughness and weldability, PCD and carbide knives made from artificial polycrystalline diamond composite Blade (PDc). Cemented carbide substrate with pressed 0.5~1mm thick layer on its surface formed by sintering PCD. Flexural strength of composite blades with carbide, hardness near to PCD, can be an alternative to PCD. PCD and artificial polycrystalline diamond compact (PDC) tool for sharp edges and processing with the workpiece surface quality than ND. While doing so their poor machinability, grinding than small, difficult under some of the geometric model of the. Currently using artificial polycrystalline diamond composite preparation tool could only still cannot be made indexable blade with chip breaker grooves and complex 3d surface geometry milling cutters.
CVD diamond thick film (TDF) welding tool
Welding of diamond thick film cutting tools are great CVD diamond thick film laser cut welded on the substrate (typically cemented carbide to the k class), occurance of PDC and polishing compound, welded to the body with the second time, grinding into the required shape and leading edge. Figure 3 (a) below, and CVD diamond thick films (diamond-like carbon film thickness up to 30μm), rich in hardness, wear resistance, low friction characteristics, is right material for cutting non-ferrous metal and non-metal tool manufacturing. Because of diamond welding technology complex, CVD diamond thick film (TDF) welding tool will never be high-volume applications.
Diamond coated cutting tools
Diamond-coated tools are directly within the cemented carbide by CVD method (k kind of cemented carbide) or 1~25μm Diamond-like carbon films deposited on a ceramic substrate layer, no cleavage surface of isotropic. Figure 3 (b). Thin film coating tool hardness approximately 9800~10000HV. High thermal conductivity, thermal conductivity at room temperature as much as 2000W · m-1 · K-1, thermal conductivity only cemented 80~100m-1 · K-1。 CVD diamond coated tool on any complex shapes, the vast majority of this can be PCD cannot have significant advantages.
Cubic Boron Nitride (PCBN) tool
Cubic nitride boron (PCBN) is following artificial synthesis diamond zhihou appears of second species inorganic super hard material, its hardness slightly times Yu diamond, hot stability good, heat sexual can reached 1400~1500du, than diamond of heat sexual (700~800du) almost high 1 time times. cubic nitride boron (PCBN) tool main for processing various ferrous metals and alloy material; most for Yu various quenching hard steel (carbon pigment tools steel bearing steel die steel high speed steel) Pearlite ash mouth certain (vanadium titanium cast iron) Chilled cast iron high temperature alloy (nickel base alloy cobalt base alloy) plus the surface spray heap welding of processing. has using long term, reduced for knife number, compensation downtime by spent of their time, makes NC machine and Automation brand of efficient can tend to be stuffed with play, can alter traditional of machinery processing way (is quenching Qian with tool roughing and quenching Hou with wheel fine processing of method), to can in the Taiwan NC machine for quenching Qian quenching Hou of turning processing (to car generation mill), has is great of statistics.

The innovation is the diamond tool enterprise develops the source power

It is well known, the diamond tool industrial production started from the 20th century 60's, to have been through repeatedly from the European and American developed country, to Japan, to South Korea, arrived China's all previous industrial shift again, domestic was starts from 1990s to start, although started late, but passed through 20 year about development, the diamond tool profession already occupied the pivotal status in the international market.These result acquisition with fellow colleagues who presents, upstream the profession revolutionary technology transforms, as well as the association leads, is employed enterprise's joint effort is in particular cannot separate, in recent years, the profession development tendency appeared some encouraging changes in particular.
One is the diamond tool manufacturing industry from the initial simple colony type development to the intensive -like development.
Yesterday Chairman Yin Yuhang mentioned domestic at present is engaged in the diamond tool profession enterprise quantity to be multitudinous, the market competition is day by day intense, even achieves the pure price competition aspect, but this kind of competition also has positive one side, competition at the same time, also further is impelling the enterprise technology advancement, even is forces the enterprise in the fine profit, the low consumption, the high quality to enlarge the strength, also developed the positive function to the entire profession.
Two is the profession segmentation and the enterprise specialization development tendency is day by day obvious.
Along with the national economy fast development, the downstream industry segmentation and the specialized degree are more and more high, the diamond tool terminal user is more and more mature, more and more specialized, more and more is also clear about to the tool individuality demand, also will certainly to lead the tool manufacturing industry the profession segmentation and the specialized development, who complied with in this time the market demand, who will be able to grasp the market pulse, will obtain the considerable development.Yesterday the Zhengzhou New Asia's river total speech will make the extremely profound impression to me, the profession subdivided, the domain subdivides itself is one kind of specialized expanding, one product will hit the world the phenomenon to become the history.
Three is the profession technical equip fast promotion.
In the recent two years, follow the social aging degree to enhance unceasingly in particular, after as well as 90 crowds enter the society, the original technical equip already could not meet the need.At the same time, the equipment manufacturing industry specialization degree unceasing enhancement, has provided the guarantee for the diamond tool manufacturing industry technical equip promotion.The technical equip specialized promotion manifests in two aspects, one is the precise and advanced equipment appearance, two is the automatic equipment popularization.
Four is the diamond tool manufacturing industry third industrial shift starts to appear.
Regarding the diamond tool manufacturing industry, European and American developed country today is our tomorrow, this will be a law of development.The home industry appears the shift two very important factors to be decided once more by our country national economy development and the third party state economy development, along with the domestic resources class commodity regulation and the cost pressure, the industrial shift demand starts to appear, simultaneously, is following the third party country economical development and the market demand expansion, the industrial shift becomes one kind of necessity.
The above is I to diamond tool profession trend of development several understanding, mainly is positive one side, certainly we are undeniable, the vigorous development behind, we also have very many insufficiencies.Yesterday Chairman Yin Yuhang already summarized extremely comprehensively, I wanted to elaborate from three aspects.
One is the profession enterprise is multitudinous, but big and is not strong.
On the century at the beginning of 90's, the domestic diamond tool manufacturing industry starts to start, simultaneously also is the profession practitioner's best market enters the time, through got rid of Japan the Han enterprise while domestic market monopoly status, the practitioner has also obtained the rich profit, and obtained the considerable development.But the recent years practitioner entered the market massively, the market competition is day by day intense.The certainly full competition is advantageous to the impetus profession whole development, but we do not accommodate a fact which avoids are, the profession practitioner's increase, is one kind of simple fission to a great extent, is the fund and the technical simple duplication, very little has the archery target change.
Two was the profession high end technology and the product still grasps in Europe and America, Japan and so on in the developed country hand.
In any international domain industrial shift process, all is containing the helpless, is containing inevitably, but simultaneously is containing strategically.On the diamond tool manufacturing industry, the European and American developed country practitioner cannot break its monopoly status to give up the profit on own initiative, but along with its cost pressure as well as the overseas technical economy development, it reduces gradually in the competition superiority status, the industry shifts into, simultaneously also is inevitably containing overseas practitioner's many helplesses.On the other hand from looked, industrial shift inevitable behind, also has its strategically, is one resources and the manpower cost shift, the high end technology and the product still grasped in Europe and America and so on in the developed country hand, like in the aerospace, the electron and so on many domains, these domain product still had the very high added value.
Three was the international brand and the channel construction still waits for the enhancement.
Looked from the entire profession development and the market distribution that, at present the domestic enterprise also is in the disadvantageous aspect in the international market competition, in Europe and America and so on the developed country, it passes through in particular many year development, quite was already mature in the brand and the channel construction aspect, the industrial shift became one kind to produce to a great extent can shift, the European and American countries still obtained the high income on the brand and the channel.
Above viewpoint is my some views, because I am engaged in the diamond tool manufacturing industry time quite to be short, some views can exist biased some.But I believed that, this is one developing nation profession development one must pass through the stage, if everybody sets level the point of view, finishes the enterprise solidly, this stage will be able to reduce greatly.How the correct analysis at present the profession present situation and do the trend of development, achieve adroitly guide action according to circumstances also are maintain the enterprise healthy development the essential condition.Below I discussed the abundant deep tool limited liability company the situation, encourages each other with everybody.I was join abundant deep tool this big family in 2002, in these 10 year work period, I experienced the company to develop the success going on the market stage fast.What if abundant deeply makes the impression deeply to me is? That is the innovation.
