Nowadays, many fields use PCD cutting tools, and selecting the right tool is essential to meet work demands. Choosing an incorrect tool can decrease efficiency and directly affect work quality. Therefore, it's important to select the right tool based on practical production conditions to achieve optimal results.
The dimensions of PCD cutting tools must be suitable for the surface dimensions of the workpiece being processed.
In production, a milling cutter is often used for processing peripheral contours of planar parts.
When milling a flat surface, a hard metal alloy PCD milling cutter should be used.
When processing a convex platform or groove, a high-speed steel milling cutter should be used. When processing the surface of a blank or rough-holed part, a corn milling cutter with embedded tungsten carbide can be used.
For processing some three-dimensional surfaces and variable angle contour shapes, a ball head milling cutter, ring milling cutter, cone milling cutter, or disc milling cutter are commonly used.
When using a machining center, various cutting tools are placed in the tool magazine and can be selected and changed according to a programmed sequence.
Therefore, standard shanks must be used so that standard PCD cutting tools for drilling, boring, expanding, and milling can be quickly and accurately mounted on the machine spindle or tool magazine. Programmers should understand the structural dimensions, adjusting methods, and adjustment ranges of the tool holders used on the machine tools so that they can determine the radial and axial dimensions of the cutting tools when programming.
In the case of freeform surface (mold) processing, the cutting speed at the end of a ball head tool is zero. Therefore, to ensure precision processing, a close pitch is typically used in cutting paths of the tool's tip. Thus, ball head cutters are commonly used for surface finishing on curved surfaces.
Flat head cutters have better surface processing quality and cutting efficiency than ball head cutters. Thus, as long as overcutting is avoided, flat head cutters should be preferred for both rough and finishing processing of curved surfaces.
In summary, material selection for PCD cutting tools is also very important when making a selection. Only by understanding the performance of PCD milling cutters and other cutting tool materials can efficiency be improved and costs saved. These materials have high hardness and wear resistance at high temperatures, necessary bending resistance, shock toughness, chemical inertia, good processability, and are not easily deformed.
