When customize some metal parts, sometimes we choose to manual machining, sometimes we need cnc machining. So, what are the differences between them? Here are something we prepare for you.
Here we take processing aluminum profile as example to show you some differences.
Common machines and CNC machines
The equipment commonly used by industrial aluminum profile processing manufacturers is cutting machine, punching machine, tapping machine, etc. These devices are all manual equipment. When the scale of industrial aluminum profile processing manufacturers is large, a high-precision equipment will be added, which is CNC numerical control. Equipment, this kind of equipment is different from ordinary equipment, specifically what is different, the following article will give you a brief introduction.
The conventional frame assembly of industrial aluminum profiles does not need to be processed by CNC milling, but in special cases, non-standard parts and profiles are used together, and when functions are expanded, aluminum profiles need to be processed by CNC according to technical requirements.
CNC numerical control machine tool is an automatic machine tool equipped with a computer control system. Usually there are CNC processing machine tools, CNC processing milling machines, CNC processing boring and milling machines, etc. Aluminum profile CNC processing is a new processing technology. Its advantage is that the precision of the processed aluminum profile parts is quite high, and the surface is bright and shiny, which can meet the requirements of most enterprises for the accuracy of aluminum profiles and can improve aluminum profile manufacturers’ efficiency in the process, as well as reduce the defective rate, save the cost of production, and shorten the delivery time.
CNC processing in industrial aluminum profile processing is a new type of processing technology. The main job is to compile processing programs, that is, to convert the original manual work into a computer. However, manual processing experience is still required. CNC processing belongs to CNC lathe processing. , The determination of the processing route generally follows three principles.
The use of CNC machining equipment first ensures the accuracy of the workpiece to be processed and the roughness of the surface, and then shortens the processing route and reduces the time of idle travel, thereby improving the efficiency of processing.
Then it is necessary to simplify the workload of numerical calculation as much as possible, so as to simplify the processing procedure. Then, for some reusable programs, you need to use subroutine operations.
Many profile manufacturers can do profile processing, but they don’t necessarily use CNC equipment. Because CNC equipment occupies a relatively large area, it needs professional personnel to operate it, which will undoubtedly increase the cost input for small businesses. But if you want high-precision processing, you must use CNC equipment to ensure that the error is in the smallest range.
Ordinary equipment cannot be programmed and controlled like CNC equipment, it is completely manual operation by personnel, and the efficiency is slow. CNC processing equipment can be operated in batches, not only with high precision, but also can be programmed arbitrarily to remove unnecessary parts, such as drilling, tapping, milling, cutting, etc., can be completed in one step, and the delivery time is shorter.
To sum up:
Advantages of CNC machining:
- Higher effiency
- Higher accuracy
- Shorter delivery time
Advantages of manual processing:
- No need large area for the machines
- No need large initial investment to buy the machines
