The characteristics of red copper
oxygen-free red copper has no hydrogen embrittlement, high electrical conductivity, good processability, weldability, corrosion resistance and low temperature performance. Copper has good heat transfer, elongation and corrosion resistance.
The scope of application of copper
Red copper materials are mainly used in electric vacuum instrument parts. Widely used in busbars, conductive strips, waveguides, coaxial cables, vacuum seals, vacuum tubes, parts of transistors, etc. It is also used in the processing of motor short circuit rings, electromagnetic heating sensors, high-power electronic components, terminal blocks, doors, windows, handrails and other furniture and decorations.
Why choose PCD tools to process copper?
Copper is widely used due to its good toughness and plasticity, but it is easy to stick to the cutting tools during processing.
PCD tools can process non-ferrous metal materials and their alloys such as: aluminum alloy, aluminum casting alloy, magnesium aluminum alloy, silicon aluminum alloy, copper alloy, red copper, brass, tungsten carbide hard alloy, ceramics and other materials.
PCD inserts can be used for high-speed cutting, which can effectively improve production efficiency and save production costs. PCD tool processing copper materials can obtain better surface finish and improve surface processing quality.
How to grind PCD tools for processing copper?
when the copper material is relatively sticky to the cutting tools, the most important thing in processing is that the rake angle must be large when grinding the turning tool, and the chip flute must be opened greater than 5mm, and the depth is best Between 2mm and 3mm, it is not easy to generate heat when turning copper materials, and the turning process is smoother and the surface finish is better.
Moresuperhard provide vitrified diamond grinding wheel for grinding PCD tools including pcd turining tools,pcd milling tools and pcd reamers.Moresuperhard provide 11A2,1A1,3A1,14A1 and other specifications diamond grinding wheel for pcd tools chipping breaker processing.
Customers use ceramic diamond cylindrical grinding wheels to grind PCD roller tools. At first, the customer was not satisfied with the chipping effect of using a domestic brand grinding wheel. Currently, customers use a resin diamond grinding wheel from a certain European brand to achieve better grinding results, but the cost is relatively high.
A diamond roller is a high-efficiency, long-life, low-cost grinding wheel dressing tool that uses electroplating or powder metallurgy methods to inlay a large number of diamond particles on the surface of a steel roller. It is used for special machine tools and gear grinders for mass form grinding. Rotating at a certain speed (thereby reducing the relative speed between the roller and the grinding wheel) produces grinding and rolling effects on the surface of the high-speed rotating grinding wheel, so that the grinding wheel obtains a sharp working surface that matches the roller profile.
