overview
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.
Main indicators
The hardness of PCD can reach 8000HV, which is 8~12 times of the
hard alloy;
The thermal conductivity of PCD is 700W/mK, which is 1.5~9 times of
cemented carbide, even higher than PCBN and copper, so PCD tool
heat transfer quickly;
The friction coefficient of PCD is generally only 0.1~0.3(the
friction coefficient of carbide is 0.4~1), so PCD tool can
significantly reduce the cutting force;
The thermal expansion coefficient of PCD is only
0.9×10^-6~1.18×10^-6, only equivalent to 1/5 of the cemented
carbide, so PCD tool thermal deformation is small, high processing
accuracy;
PCD tools and non-ferrous and non-metallic materials between the
affinity is very small, in the process of processing chip is not
easy to stick on the tip of the knife to form a chip tumor.

Q: Are you Manufacture?
A: Yes, we are manufacture. we produce our “JOEBEN“brand tools for gurantee the quality.
We also trading related tools for customers because we are in these
field over 10 years, we are very familiar Chinese market tools. we
usually help our customer choose the best suitable related tools
for them.
Q: What is your delivery time?
A: Most of models are ex-stock, if out of stock,there usually need
about 3-5 days or 7-10 days.
Q: Can you produce non-standard tools?
A: Yes, we can produce non-standard tools as per your drawing.
We also can design tools for you as per your usage requirement
Q: What is your advantages?
A: We are factory who produce our own brand “JOEBEN” tools, we must gurantee our brand quality. Also, we have factory
price and fast delivery.
Our advantage:
- 1. 10 years experience in carbide roll and cutting tool
manufacturing
- 2. From row material to tool produdtion.
- 3. World top level prodution equipment and rich experience team
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.
