In order to meet the requirements of the main transmission of CNC lathe processing, CNC machine tools (attribute: automatic machine tools) often use a motor stepless speed regulation system. The method of combined speed regulation can realize the spindle speed regulation. In numerical control processing, the control system sends out instructions to make the cutter…

Modern CNC machine tools are CNC machine tools, which are generally composed of CNC operating systems and machine tool bodies. The equipment specially used for processing metal or wood mainly consists of the following parts.

CNC machine tool (attribute: automatic machine tool) processing is a high-precision and high-efficiency automatic machine tool. Using CNC machine tool processing can improve the processing benefit (benefit), create more value, and get rid of the backward processing technology. The processing technology of CNC lathes is similar to that of ordinary lathes. What are the advantages…

(1) The dimension marking method in the CNC machining parts drawing The size on the parts drawing is an important basis for manufacturing and inspecting parts. The production requires that the size in the parts drawing does not allow any errors. CNC machining generally CNC machining usually refers to computer digitally controlled precision machining, CNC…

The transmission gear in the feed system of the CNC machining machine must eliminate the transmission gap between the meshing gears as much as possible, otherwise the movement will lag behind the command signal after each reverse of the feed system, affecting the processing accuracy (Accuracy). There are two common methods for CNC machining machine…

The static pressure slide rail (TTW guide) of the CNC machining lathe is to transfer the oil with a certain pressure to the oil chamber between the sliding surfaces of the slide rail (TTW guide) through a throttle to form a pressure oil film to float the moving parts , The surface of the slide…

CNC machining lathe plastic (structure: synthetic resin, plasticizer, stabilizer, colorant) slide rail (TTW guide) is the same static and dynamic friction coefficients on the slide rail matched with the bed guide rail, basically the same, wear-resistant 、 Vibration-absorbent plastic soft belt, or plastic rail is made by injection molding between fixed and moving rails. This…

The feed drive of CNC machining tools has high requirements on position accuracy (precision), fast response performance, and speed adjustment range. In numerical control processing, the control system sends out instructions to make the cutter perform various movements that meet the requirements, and expresses the processing of technical requirements and processing requirements such as the…

The feed motion of CNC machining tools is the direct object of digital control. Whether point control or contour control, the final dimensional accuracy (accuracy) and contour accuracy of the workpiece are affected by the transmission accuracy and sensitivity of the feed motion (Sensitivity) and stability (explanation: stability and stability; no change). To this end,…

Generally, the spindle components of small and medium-sized CNC machining machine tools mostly use rolling bearings (bearing) as the spindle support. At present, there are mainly three deployment methods: 1. Front support adopts double-row short cylindrical roller Sub-bearing (bearing) and 60. In numerical control processing, the control system sends out instructions to make the cutter…

The most direct and effective way to reduce the processing cost is to effectively apply the turning to process different parts of the CNC tool. Therefore, in order to select the most suitable CNC tool, in addition to selecting the appropriate tool material, it is also necessary to understand the geometric characteristics of the CNC…
