In the above processing methods, EDM will be better. In the process with working fluid conditions, it
uses pulse voltage to make the working fluid near the electrode metal form a discharge channel, and
produce the partial discharge sparks, the instantaneous high temperature will make polycrystalline
diamond melt, fall off, so as to form the required triangle, rectangle or square pcd blanks.

Vacuum brazing
At present, low cost high frequency induction brazing is widely used in PCD blade welding. In the actual processing,
we can control the welding temperature (generally should be lower than 700 ℃) according to the holding time and the
depth of PCD redness . High-frequency welding using automatic welding technology, welding efficiency, good quality,
continuous production.

The high hardness of PCD leads to very low material removal rates (even one ten thousandth of the cemented carbide
removal rate). As the grinding wheel hardness is near to pcd, so the principle is complicated. Electric spark grinding
(EDG) technology isn't hardly affected by the hardness of the workpiece, soEDG grinding has great advantages. With
the continuous development of electric spark grinding technology, EDG technology will become a major development
direction of PCD grinding.

PCD Insert with Chipbreaker
In the process of semi-finish and finish turning aluminum alloy, chipbreaker insert will perform excellently:
(1)Solved the chips problems, and improve the working efficiency
(2)With high strength materials, achivieve stable process and obtain long tool life.
The main factors that we need to consider when choose pcd chipbreaker insert:
1）To make chips breaking smooth and without affecting normal cutting;
2）Need to control the chips volume, make it easily to handle with.
3）The chips need to be removed without winding the workpiece

The application details of PCD Insert
（1）Ferrous metal
（2）Non-metal materials
When machining Copper, Zinc, Aluminum ect ferrous metal and other alloy, the materials will be easily
adhesion tool, it will be difficult to machine. Because of the low Coefficient of friction and the small Affinity
with metal of the pcd tools,we can get higher surface quality and slove the problems, improve the efficiency.
When processing fiber glass-reinforced plastics, silicon-filled materials, and hard carbon fiber/epoxy resin
composites, Tunsten carbide insert will be easily wear and difficult to machine, PCD tools will have high
hardness, good abrasive resistance and high process efficiency.

PCD Insert for Aluminum alloy part---Automotive Pistons
In order to improve the performance of the Automotive engine, Most automotive pistons will change
the materials from Aluminum with low content silicion to Aluminum with medium or high content
silicion which improve the components' hardness and abrasive resistance. PCD Insert with excellent
performance is widely used for aluminum alloy.
