How to choose the cutting tool for machining hardware parts

CNC milling machine is divided into two categories: without tool library and with tool library. The CNC milling machine with tool library is also called machining center. Be able to process sophisticated hardware parts with unique and complex appearance or difficult to control size, such as mold parts, shell parts, etc. The cutting tool used in the machining center of the sophisticated hardware parts is composed of the general cutting tool and the tool handle matched with the taper hole at the front end of the spindle of the machining center. In the process of machining, there are many factors to be considered, such as the function of the machine tool, the rigidity of the fixture, the function of the workpiece raw material, the cutting amount and other related factors.

The general principle of tool selection in machining center is: good rigidity, easy installation and adjustment, high durability and precision. In addition, in order to increase the rigidity of the tool and ensure safety, the extension length of the tool should be as short as possible. On the machine tool of the sophisticated hardware parts processing center, all kinds of tool farewell are installed in the tool magazine and processed according to the regulations of the program.

Variety of cutting tools in machining center: there are many kinds of cutting tools in the machining center of well-designed hardware parts, which are widely used and compared with various kinds of surface and hole machining tools. The milling cutters of various types are mainly selected for the machining of plane and curved surface, while the hole machining tools can select drills, reamers, reamers, boring cutters, etc. according to the form, location and accuracy requirements of the holes to be machined. The carbide spiral end milling cutter is mainly used for processing cast iron, steel, non-ferrous metal and other materials. The blade is usually welded. The indexable spiral end milling cutter is mainly used for rough milling of large workpiece steps, elevations and large grooves.
