5052 alloy aluminum plate diamond coated tool and usually coated tool geometric Angle is substantially different, therefore, in the planning of diamond coated tool, because of the graphite processing of the singularity, the geometric Angle can be appropriately reduced, chip slot is also larger, and will not reduce the wear resistance of the cutting edge. With regard to the usual TiAlN coating, although its wear resistance is significantly improved compared to the uncoated tool, compared to the diamond coating, the geometrical Angle should be appropriately reduced when machining graphite to increase its wear resistance. 5052 alloy aluminum plate for diamond coating, now many coating companies in the world are invested in a few human and material resources to study and develop relevant know-how, but so far, foreign know-how and good economic coating companies are limited to European companies. Tool edge reinforcement Tool edge passivation is not widely regarded by us, but very important question. The cutting edge of carbide tool with diamond grinding wheel has different level micro notch (i.e. small broken edge and serration). The high speed cutting of graphite has put forward a higher request for the tool function and stability, especially the diamond coating tool, in order to ensure the stability of the coating and the use of life before coating through the blade passivation treatment.
The policy of 5052 alloy aluminum plate tool passivation is to deal with the micro gap of the cutting edge of the tool after grinding, reduce its sharpness, reach smooth, reliable and used policy. Cutting conditions The selection of cutting conditions has an equally great effect on tool life. Cutting methods (down milling and down milling) The cutting vibration of down milling is less than down milling. Along milling, gear reducer cutting tool thickness is reduced from the maximum to zero, cutting tool cutting workpiece, 5052 alloy aluminum plate will not emerge because of cutting chips and formed by the spring knife scene, the skill system is good rigidity, cutting vibration is small; Conventional milling, the cutting tool from zero is added to the biggest cut thickness, cutting tool to cut into the early because of cutting thickness thin, appearance in the workpiece to draw a way, at the moment, the edge assumes that hit hard point or residual graphite material guess chip particles in workpiece appearance, will cause the cutting tool of a knife or flutter.
So conventional milling cutting vibration is larger. 5052 alloy aluminum plate blowing (or vacuuming) and dipping edM processing in time to clear the surface of the workpiece graphite dust, is conducive to reduce the tool secondary wear, extend the tool life, 5052 alloy aluminum plate adding graphite dust on the machine tool lead screw and guide rail. Other matters select the appropriate high speed and the corresponding large feed. Summary of the above points, the material of the tool, geometric Angle, coating, suzhou Shuoyuan Aluminum Co., Ltd. edge strengthening and cutting conditions, in the use of the tool life performance is not the same character, one cannot be absent, complement each other. A good graphite tool should have fluent graphite powder chip discharging groove, long service life, can carry out deep carving processing, can save processing costs.
