Advantages of Single Crystal Diamond Tools
With the advent of modern integrated technology, machining is developing in the direction of high precision, which places very high requirements on tool performance. Due to the small friction coefficient, low thermal expansion coefficient and high thermal conductivity of single crystal diamond, it can cut extremely thin chips. The chips flow out easily. It has low affinity with other substances and is not easy to produce built-up edge. It generates little heat and has high thermal conductivity. It can Avoid the impact of heat on the blade and workpiece, so the blade is not easily dulled, the cutting deformation is small, and a higher quality surface can be obtained.
Customer CVD diamond tools grinding case
Workpieces :Inner concave MCD/CVD cutting tools
Grinding Requirement:Chipping control under 5μm
Grinding machine:Anca cnc grinding machine
Customer try to use resin bond diamond grinding wheel for grinding CVD single crystal diamond tools,But there are two problems that need to be solved.
1.Chipping control:The chipping is not up to standard and cannot be controlled within 5μm.
2.Low grinding efficiency:The grinding wheel is consumed too quickly, but the amount of workpiece removal is not obvious.
Moresuperhard has rich experience in grinding CVD/MCD diamond cutting tools.Usually,vitrified bond diamond grinding wheels are more suitable for grinding single crystal diamond cutting tools and moresuperhard' fine grain sizes ceramic diamond grinding wheel has good performance in grinding diamond tools.
According to the customer's grinder, Moresuperhard customizes a 1A1 parallel ceramic diamond grinding wheel for testing.Let’s look forward to a successful test result.
Comparison of the grinding effects of single crystal diamond tools with different particle size ceramic diamond grinding wheels in Moresuperhard
| Grain Sizes | Chipping |
| W20 | 30μm-35μm |
| W10 | 15μm-20μm |
| W5 | 5μm-7μm |
| W1.5 | 3μm-5μm |
This is a grinding experiment data,the specific grinding results need to be determined according to the grinding machine and grinding parameter settings.
<< ：Applications of diamonds with different crystal structures
<< ：The future of indexable inserts and peripheral grinding wheels
PDC cutters are widely used for gas,oli drilling,coal minning etc.Grinding procession will directly influence the quality od PCD cutter.Moresuperhard provide diamond grinding wheel for grinding different parts of pdc cutter like surface grinding,external grinding wheel ,double-sided grinding disc and centerless grinding wheel.
In the grinding industry, ceramic diamond double-end grinding discs have attracted much attention for their high efficiency and high precision. In order to help newcomers quickly master the core knowledge in this field, Moresuperhard specially invited Jim, a sales expert in double-end grinding discs, to conduct a systematic training. From basic concepts to practical applications, this training content is full of practical content. Of course, in order to test the learning results, Jim assigned homework to everyone. The students' answers are all very good, which are summarized as follows for everyone to learn and refer to.
