overview

Polycrystalline Diamond PCD Insert:

PCD (Polycrystalline Diamond) is a synthetic diamond product that is produced by sintering together selected diamond particles with a metal matrix, using sophisticated technology. The diamond and matrix, when sintered together under high temperatures and pressures, creates a PCD tool blank that is high in uniform hardness and is abrasive resistant in all directions. PCD Inserts is made of PCD tips( cutting from PCD blank) and a carbide substrate.

Diamond tool has the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, which can obtain high machining accuracy and processing efficiency in high-speed cutting. The above characteristics of the diamond tool are determined by the crystal state of the diamond. In diamond crystals, the four valence electrons of carbon atoms are bonded by tetrahedral structure, and each carbon atom forms a covalent bond with four adjacent atoms, thus forming a diamond structure, which has a strong binding force and directivity, so that diamond has extremely high hardness. Because the structure of polycrystalline diamond (PCD) is a fine crystalline diamond sintered body with different orientation, the hardness and wear resistance of PCD are still lower than that of single crystalline diamond although the binder is added. However, because the PCD sintered body is isotropic, it is not easy to crack along a single cleavage plane.

The hardness of cubic boron nitride (CBN) is second only to PCD and single crystal diamond. It can maintain the hardness of cemented carbide at 25 ℃ at 1000 ℃. The high strength of CBN comes from its intergranular bond. With the hardness alloy matrix with good hardness and toughness, the tool made of it can bear great cutting force when deep cutting high hardness and toughness materials, and the intergranular bond can also provide high impact strength, which is very necessary when cutting continuous and discontinuous sections.

1. Look at the processing process: if the processing process, continuous regular sparks, indicating that the tool has been worn, according to the average life of the tool
Change knives in time.
2. Look at the color of the iron filings: the color of the iron filings changes, indicating that the processing temperature has changed, and this time the tool has begun to wear.
3 Look at the shape of the iron filings: zigzag on both sides of the iron, abnormal curling of the iron filings, and the iron filings become finer, which are all tools
The judgment basis of damage.
4. Look at the surface brightness change of the workpiece: the brightness continuously reduces the tool has been worn.
5 Processing vibration sound changes: tool wear will cut the resistance is too large, pay attention to avoid "knife", resulting in workpiece scrap
6. Observe the change of machine load data: If there is a significant incremental change, it indicates that the tool has been worn.
7. Observe the burr change on the edge of the workpiece: when the tool is cut out, the workpiece has a serious burr and the phase roughness decreases.
8. Observe the size change of the workpiece: obvious phenomena such as the size change of the workpiece are also the criteria for tool wear.
9. Tool life table (based on the number of processed workpieces): some high-end equipment manufacturing or single product mass production enterprises use it to guide production, this method is suitable for processing expensive aerospace, steam turbines, automotive key components such as engines and other production enterprises.

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.
