Characteristics and operation specifications of special CNC machine tools

Special machine tool is a kind of machine tool specially suitable for the processing of specific parts and specific processes. It is an indispensable variety of machine tools in the automatic production line manufacturing system. Because the special machine tool is a customized product with the advantages of automation, it is an ideal equipment for mass production enterprises.

With the progress of equipment manufacturing technology and the popularization of numerical control technology, the numerical control of special machine tools is also developing rapidly. Special machine tools occupy a certain proportion in production practice. The manufacturing of special machine tools and their automatic production lines is different from the mass production of automobiles and ordinary machine tools. It has two extremely distinctive characteristics.

One is integration, which integrates the development, design and selection of machine tools, fixtures and tools, inspection and measurement, logistics transportation, chip and coolant protection and treatment. It not only solves one of these problems, but also solves every problem that may be encountered in a wide range of technical fields. Second, unity. Almost all special-purpose machine tools are single production. According to the requirements put forward by users, they should be developed and manufactured at one time, and ensure one-time success.

In the operation of special CNC machine tools, the staff should stick to their posts, operate carefully and do nothing irrelevant to the work. When leaving the special machine tool for something, stop the machine and turn off the power and air source. Process according to the process regulations. It is not allowed to arbitrarily increase the feed, grinding and cutting (grinding) speed. It is not allowed to use special machine tools beyond the specification, overload and weight. Rough use of fine machines and small use of large machines are not allowed.

The cutting tools and workpieces of special machine tools shall be clamped correctly and fastened firmly; Special machine tools shall not be damaged during loading and unloading; Align the cutting tools and workpieces, and do not knock them with a heavy hammer; It is not allowed to fasten the cutting tools and workpieces by lengthening the handle and increasing the torque; It is not allowed to install thimbles, cutting tools and tool sleeves that are inconsistent with their taper or hole diameter, with nicks on the surface and unclean in the spindle taper hole, tailstock sleeve taper hole and other tool installation holes of special machine tools.

The mechanical speed change of the transmission and feeding mechanism, the clamping and alignment of the tool and the workpiece, and the manual measurement between the working procedures of the workpiece shall be stopped after the cutting and grinding are terminated and the tool and abrasive tool are retreated from the workpiece. The cutting tools and abrasives shall be kept sharp. If they become blunt or crack, they shall be sharpened or replaced in time.

Tools, workpieces and other sundries are not allowed to be placed directly on special CNC machine tools, especially on the guide rail surface and worktable. Always remove the iron filings and oil stains on the special machine tool, and keep the guide rail surface, sliding surface, rotating surface, positioning reference surface and worktable clean.
