Main indicators

PCD milling cutter shall be used for turning various non-ferrous metals such as aluminum, copper, magnesium and their alloys, hard alloys and fiber plasticizer with strong wear resistance, metal matrix composites, wood and other non-metallic materials.The cutting speed, feeding speed and cutting depth conditions depend on the material and hardness of the workpiece.Due to the residual bonding metal and graphite between diamond particles, the bonding metal distribution in a coalesced or veined state will reduce the wear resistance and service life of the tool.
In addition, there are residual solvent metals, which contact the diamond surface directly.Reduce (PDC) oxidation resistance and tool heat temperature, so the cutting performance of the tool is not stable.The preparation of diamond thick film tool is complicated because of the high interfacial energy between diamond and low melting point metal and its alloy.Diamonds are difficult to infiltrate into general low - melting solder alloys.TDF welding tools cannot be used in high speed milling because of their poor weldability and difficulty in making complex geometric tools.
Diamond coated tools can be used in high speed machining because, in addition to their excellent mechanical properties, diamond coated tools can be used to prepare arbitrary complex shape milling cutters for high speed machining of aluminum and titanium alloy aviation materials and difficult to process non-metallic materials such as graphite electrode.

1. The hardness of PCD is up to 8000HV, which is 8~12 times of the hard alloy;
2, the thermal conductivity of PCD is 700W/mK, 1.5~9 times of hard alloy, even higher than PCBN and copper, so PCD tool heat transfer quickly
3. The friction coefficient of PCD is generally only 0.1~0.3(the friction coefficient of cemented carbide is 0.4~1), so PCD tool can significantly reduce the cutting force;
4. The thermal expansion coefficient of PCD is only 0.9×10^-6~1.18×10^-6, which is only equivalent to 1/5 of the cemented carbide. Therefore, the PCD tool has low thermal deformation and high machining accuracy.
5. The affinity between PCD tools and nonferrous and nonmetallic materials is very small, and the chips are not easy to bond to the tip during the processing, forming chip deposits.

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.

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.
