What are the advantages of CNC machine tools in processing
CNC machine tool is a good solution to the complex, precision, small batch, many varieties of parts processing problems, is a flexible, efficient automatic machine tool, represents the development direction of modern machine tool control technology, is a typical electromechanical integration products. What are the advantages of CNC machine tools in processing?
1. The precision is high
(1) THE structure of CNC machine tool has high stiffness and thermal stability, and measures to reduce errors have been taken. The error can also be compensated by the NUMERICAL control device, so the NUMERICAL control machine tool has a higher processing accuracy.
(2) THE transmission system of CNC machine tools adopts no clearance ball screw, rolling guide rail, zero clearance gear mechanism, etc., which greatly improves the transmission stiffness, transmission accuracy and repeat accuracy of machine tools. Advanced CNC machine tools adopt linear motor technology, so that the mechanical transmission error of machine tools is zero.
(3) The error compensation function of numerical control system eliminates the system error.
(4) CNC machine tool is automatic processing, eliminate human error, improve the processing size of the same batch of parts - induced, stable processing quality. One installation can carry out continuous processing of multiple processes, reducing installation error.
2. Able to process parts with complex shapes
The CNC machine tool with more than two axis linkage can process the parts of rotating body, CAM and all kinds of complex space surface with the bus line as the curve, and can complete the processing difficult to be completed by ordinary machine tools. For example, Marine propeller is a complex part of space curved body, which can only be processed by end milling cutter and five-axis linkage horizontal CNC machine tool.
3. High productivity
(1) Save auxiliary time
CNC machine tools are equipped with transposition tool rest, tool storage and other automatic tool change mechanism. Manipulator can automatically load and unload tools and workpiece greatly save auxiliary time. Production process without inspection, save inspection time. When machined parts change, in addition to re-clamping the workpiece and changing the tool, only need to change the program, saving preparation and adjustment time. Compared with ordinary machine tools, the productivity of CNC machine tools can be increased by 2 ~3 times, and the productivity of machining centers can be increased by more than 10 times to dozens of times.
(2) Improve the feed speed
CNC machine tools can effectively save maneuvering time, fast moving shorten the time of empty stroke, the range of feed is larger. Can effectively choose reasonable cutting dosage.
(3) Using high speed cutting
Nc machining using small diameter tool, small cutting depth, small cutting width, fast multiple cutting to improve the cutting efficiency.
The cutting force of high speed machining is greatly reduced and the spindle torque required is correspondingly reduced.
The workpiece deformation is also small. High speed cutting not only improves productivity, but also improves machining accuracy and reduces surface roughness.
