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.

General knowledge of diamond cutter
Before user inside the selection and use of diamond coated cutting tools, you will need to understand the subsequent several points regarding the diamond-coated tools common sense:
(1) Difference between CVD diamond-coated with amorphous diamond coating?
Amorphous diamond (generally known as diamond-like carbon--photograph) coating can be a carbon film deposition using the PVD process. It has both section of SP3 diamond, and part of SP2 carbon; a higher film hardness, but under the hardness of diamond-like carbon film; its thickness is thinner than we usually deposited diamond film. When processing graphite, amorphous diamond coating cutlery life usually are not 2-3 x the coated cemented carbide tool. By contrast, CVD diamond can be a pure diamond coatings deposition while using the CVD process, is the tool lifetime of cemented carbide cutting tools in machining graphite 12-20, so that you can reduce tool change times, increase the reliability, consistency and accuracy of processing.
(2) No machining of hardened steel with diamond tool?
Diamonds are formed from carbon atoms. Some material when heated, will aspirate carbon atoms in diamond and form carbides inside workpiece. Iron is just one of such materials. Whenever using diamond tool machining of iron materials, friction heat generated will spread for the carbon atoms of iron in diamond, which caused early failure as a result of chemical wear of diamond coating.
(3) heavy grinding and (or) heavy coating of diamond film coated tools quality challenging maintain because of the tool surface coating for pure diamond, diamond grinding wheels for cutter Regrinding needs a number of years. Furthermore, make it possible for the development of diamond cutting tools. Chemical properties in the preparation process will change the tool surface, due to the coating requires very precise control on the chemical characteristics, effect of cutter coated again can hardly be guaranteed.
(4) the life span of diamond coated cutting tools vary?
As with every other tool, diamond coated cutting tool life expectancy varies, dependant upon cutting materials, number of cutting speed and feed rate, and also the geometry of the workpiece. In the main, graphite machining carbide tools coated with diamond coated cutting tool life's not 10-20, in some instances even longer. In this way, you can do nearly every task processing by having a tool, no tool wear and tool change, avoid processing interrupt and recalibrate, rendering it possible to offer the unattended processing. Inside the processing of composite materials, may also get yourself a longer tool life.
It can be reported that in processing high density fiberglass, when machining composite materials like graphite and Gl0-FR4, of diamond coated cutting tools which aren't coated cemented carbide tool life can be as high as 70 times.
(5) coated with diamond peeling on the coating can prevent peeling is really a significant issue of diamond coated cutting tools, or a faqs (particularly machining materials such as carbon fibre), will result in tool own life is hard to forecast. Late 90 'of the past century, surface chemistry characteristics were identified as is a factor influencing the performance of diamond-like carbon coating adhesion. By choosing the good compatibility of pretreatment of cemented carbide chemical characteristics, the employment of appropriate technology and sedimentary respond to reasonable conditions, it is possible to reduce or remove the diamond coating peeling, stability of steady wear pattern. Within microscope observation of normal depreciation of diamond coated cutting tools come in, diamond was worn before cemented carbide substrate by stability, without edge collapse or slack.
