Mintek CBN inserts improve the efficiency by 10 times and increase the life by 3 times compared with carbide inserts.
About cutting parameters:
1, The cutting parameters are related to the characteristics of the CBN insert, the hardness, strength, and cutting characteristics of the workpiece material.
2, The cutting parameters are related to the machine tool's stability, power, chip-breaking ability, processing method, tool stress state and other factors.
3, The choice of feed rate is related to the tool's main declination angle (Kr), cutting depth, CBN inserts size, CBN inserts thickness, and its shape.
4, Selection of cutting depth. If its possible, choose the large cutting depth, but we should pay attention to balancing the load of the tool.
5, The choice of cutting speed is related to the shape of the workpiece, the organization of the workpiece, the path of the tool, the hardness and strength of the material, and the life of the designed tool.
The setting of cutting parameters is related to many factors such as machine tool rigidity, workpiece shape, workpiece material, tool structure, tool material, tool geometry angle, tool durability, etc. Choosing appropriate cutting parameters could give full play to the effectiveness of machine and tools.
Matters that should be paid attention to when using tools (not only focus on tools, but also focus on the entire cutting system)
1, Work pieceWork piece name, material, hardness, dimensional accuracy, surface quality requirements.2, Tool HolderTool holder rigidity, tool shim material, accurate positioning, reliable clamping.3, ClampingNo deformation, clamping reliability, rigidity, geometric accuracy, motion accuracy.4, CBN insertsCBN inserts, model specifications, geometric angle, edge treatment.5, Cutting parametersCutting speed(Vc), cutting depth(ap), feed rate(F).6, ProcessTool life, cutting force, surface integrity, chip breaking shape.
