Tool Conditions During Machining

When processing, the tools that need to be used must not only meet the conditions, but also meet the processing conditions, so that the processing can be carried out more smoothly, and the machining process is the same, so what are the requirements for the machining tools? to make a selection. 1 Regarding the selection of tools, when machining curved parts, in order to ensure that the cutting edge of the tool is tangent to the machining contour at the cutting point, and to prevent interference between the cutting edge and the contour of the workpiece, a ball-end cutter is generally used, and a two-edged milling cutter is used for roughing. Edge milling cutters for finishing and finishing; when milling larger planes, in order to improve production efficiency and improve the surface roughness of machining, generally use insert-type disc milling cutters; when milling small planes or stepped surfaces, generally use general-purpose milling cutters; When milling the keyway, in order to ensure the dimensional accuracy of the slot, a two-edged keyway milling cutter is generally used.

      CNC machining tools must adapt to the high speed, high efficiency and high degree of automation of CNC machine tools, and generally include general tools and special tools. According to the materials used in the manufacture of cutting tools, it can be divided into high-speed steel cutting tools, carbide cutting tools, diamond cutting tools, other materials cutting tools; knowledge of product structure. Since the prototype is made of a whole piece of material, most of the equipment can only process the vertical surface, and some concave side walls are difficult to be machined in place at one time, so it needs to be disassembled by programmers. If the functions required by the finished product cannot be affected, it requires the programmer's understanding and knowledge of the structure to ensure that it is made.

      However, the technical content of the corresponding CNC machining is higher than that of ordinary lathes, so it requires higher mental work than ordinary lathes.
