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 of CNC machine tools?
1. High productivity
The CNC machine tool can effectively reduce the processing time and auxiliary time of the parts. The spindle speed and feed range of the CNC machine tool are large, allowing the machine tool to perform powerful cutting of large cutting amounts, the rapid movement and positioning of the moving parts of the CNC machine tool and high-speed cutting , Reduce the inter-process turnaround time of semi-finished products, improve production efficiency.
2. High processing accuracy
The machining accuracy (accuracy) of CNC machine tools can generally reach 0.005 to 0.1mm. The CNC machine tools are controlled in the form of digital signals. When the CNC device outputs a pulse signal, the moving parts of the machine tool move a pulse equivalent (generally 0.001mm), and the average error of the backlash of the machine tool feed drive chain and the screw pitch can be compensated by the CNC device, so the positioning accuracy of the CNC machine tool is relatively high. CNC machining CNC is also known as computer gong, CNCCH or CNC machine tool. It is actually a name from Hong Kong, which greatly reduces the number of tooling. CNC machining of parts with complex shapes does not require complicated tooling. CNC machining is a new type of processing technology and the main work It is to compile the processing program, that is, to convert the original manual to computer programming. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.
3. Highly flexible
In ensuring the surface accuracy (accuracy) of the workpiece, it mainly depends on the processing procedure (procedure), which is different from ordinary machine tools, there is no need to manufacture and replace many tools and fixtures, and there is no need to adjust the machine tool often. CNC machining generally CNC machining usually refers to computer digitally controlled precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. The feed route for finishing is basically carried out along the contour of its parts. Therefore, the work of determining the feed route is to determine the feed route for rough machining and empty stroke. Therefore, CNC machine tools are suitable for occasions where the parts are frequently replaced. That is suitable for single-piece, small batch production and new product development, shortening the production preparation cycle and saving a lot of cost of process equipment.
4. The processing quality is stable and reliable
Processing the same batch of parts, on the same machine tool, under the same processing conditions, using the same tool and processing program, the tool path is exactly the same, the consistency of the parts is good, and the quality is stable (Explanation: stable and stable; no changes)
5. Conducive to the modernization of Production Management
CNC machine tool (attribute: automatic machine tool) can accurately estimate the processing time in advance, and the tools and fixtures used can be standardized and modernized. CNC machine tools use digital signals and standard codes as control information, which is easy to standardize processing information. It has been organically combined with computer-aided design and manufacturing (CAD / CAM) and is the basis of modern integrated manufacturing technology. .
6. Improve working conditions
After the CNC machine tool (attribute: automatic machine tool) is adjusted before processing, enter the procedure and start, the machine tool can automatically continue processing until the end of processing. 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 shape and size of the workpiece in the form of numbers and letters. It generally refers to the process of processing parts on CNC machine tools. In order to improve production automation, shorten programming time and reduce CNC machining costs, a series of advanced CNC machining technologies have also been developed and used in the aerospace industry. The operator is mainly the work of program input, editor, loading and unloading parts, tool preparation, observation of processing status, inspection of parts, etc. The labor intensity is greatly reduced, and the labor of the machine tool operator tends to be intellectual. In addition, the machine tool is generally closed processing, which is clean and safe.
