CNC PCD Forming Cutter Diamond
overview
Diamond cutter
The choice of PCD particle size is related to the tool processing
conditions, such as the design of precision or ultra-precision
machining tools, should choose high strength, good toughness, good
impact resistance, fine grain PCD.Coarse-grained PCD tools can be used for general roughing.The particle size of PCD material has a significant influence on
tool wear and breakage.The results showed that the larger the PCD particle size, the
stronger the anti-wear performance of the tool.The PCD particle size includes submicron, 2mm, 5mm, 10mm, 25mm and
2-30mm, among which the CDW010 material with 10mm particle size is
of universal type, which has good anti-chip and wear resistance.
Generally speaking, the larger the particle size is, the more wear
resistance of the blade material is, while the CDW302 material with
mixed particle size of 2-30mm has better wear resistance.As shown in the figure, there are the comparison of anti-breakage
edge and wear resistance of different PCD particle sizes, as well
as the comparison of discharge characteristics and grindability.
The high hardness of PCD makes the removal rate of its material
extremely low (even only 10, 000 percent of the removal rate of
cemented carbide).At present, the PCD cutting tool grinding technology mainly adopts
the ceramic bond diamond grinding wheel for grinding.Because the grinding between grinding wheel abrasive and PCD is the
interaction between two materials with similar hardness, the
grinding law is more complicated.For high particle size and low speed grinding wheels, the use of
water-soluble coolant can improve the grinding efficiency and
accuracy of PCD.The choice of grinding wheel binder depends on the type of grinding
machine and processing conditions.Since EDG technology is almost unaffected by the hardness of the
workpiece being ground, EDG technology has great advantages in PCD
grinding.There is also a great demand for this flexible grinding process for
certain complex shape PCD tools, such as woodworking tools.With the continuous development of EDG grinding technology, EDG
technology will become a main development direction of PCD
grinding.
Folding cutting speed
PCD tool can be used for machining at very high spindle speed, but
the influence of cutting speed on machining quality cannot be
ignored.Although high speed cutting can improve the machining efficiency,
but in the state of high speed cutting, the increase of cutting
temperature and cutting force can make the tip of the tool damaged,
and make the machine vibration.When machining different workpiece materials, the reasonable
cutting speed of PCD tool is also different. For example, the
reasonable cutting speed of milling Al2O3 laminate floor is
110~120m/min.The reasonable cutting speed for turning SiC particle reinforced
aluminum matrix composites and silica based engineering ceramics is
30~40m/min.
Folded feed
If the feed amount of PCD tool is too large, the residual geometric
area on the workpiece will increase, resulting in an increase in
surface roughness.If the feed is too small, it will increase the cutting temperature,
cutting life.
Folded cutting depth
Increasing the cutting depth of PCD tool will increase cutting
force and cutting heat, which will aggravate tool wear and affect
tool life.In addition, the increase of cutting depth is likely to cause PCD
tool edge breakage.
PCD tools with different particle size grade show different cutting
performance when machining different workpiece materials under
different processing conditions, so the actual cutting parameters
of PCD tools should be determined according to specific processing
conditions.

ATTACTION:
- 1. Make sure work piece and machine are stable and use a precision
holder.
- 2. Please adjust the speed,feed and cutting depth according to
actual cutting conditions.
- 3. The milling conditions are for an end mill where the tool
overhang length is less than 4*D(mill diameter). When the tool
overhang length is longer, please adjust the speed,feed and cutting
depth.
