CNC machining is a kind of high-precision automatic machine
tool. The use of CNC machine tools can improve processing efficiency, create
more value, and get rid of backward processing technology. The process of
CNC lathes is similar to that of ordinary lathes. So, what are the advantages
and characteristics of CNC lathe processing?
1. High productivity
CNC lathe processing can effectively shorten the processing time of parts and
auxiliary time, shorten the processing time of semi-finished products, and
improve production efficiency.
2. High machining accuracy
CNC lathe machining accuracy can generally reach 0.005-0.1 mm. Controlled by
digital signals. The moving parts of the machine move one pulse equivalent
(usually 0.001 mm) for each pulse signal output by the device. In addition, the
average error between the feed chain backlash and pitch can be compensated.
Therefore, position accuracy can be set high.
3. Highly flexible.
In order to ensure the accuracy of the workpiece surface, mainly depends on
the processing technology different from the ordinary machine tool, so do not
need to manufacture and replace a lot of tools and fixtures, also do not need to
adjust often. So suitable for frequent replacement parts. Suitable for
single-piece, small batch production, and new product development, shorten the
production preparation cycle and save a lot of process equipment costs.
4. Stable and reliable processing quality.
Processing the same batch of parts, on the same machine tool, under the same
processing conditions, using the same tool and processing technology, tool
trajectory is exactly the same, parts consistent, stable quality.
5. It is conducive to the modernization of production management
CNC lathe processing can accurately estimate the processing time in advance,
and the use of tools and fixtures can be standardized, and modernized
management. Digital signals and standard codes are used as control information
to facilitate the standardization of processing information. At present, it has
been organically combined with computer-aided design and manufacturing
(CAD/CAM), which is the basis of modern integrated manufacturing technology.
6. Improve working conditions
Before processing, the CNC machine tool is adjusted, and the program input
and the start can be automatically continuous processing, until the end of the
processing. Operators mainly input, edit, load, and unload parts, prepare tools,
observe machining status, check parts, etc. The labor intensity is greatly
reduced, and the work of machine tool operators tends to be intelligent. In
addition, machine tools are usually closed, which means clean and safe.
7. Through the use of "virtual software", you can conduct training on the use
of numerical control. This software allows an operator to practice using a CNC
lathe on a computer screen. This software is similar to computer games, which
can make the learning process fun and easy to learn.
8. Acceleration and deceleration measures are adopted for fast movement and
positioning of moving parts, and high speed is selected for empty stroke.
Compared with the ordinary lathe, much less time is spent on fast forward,
fastback and positioning. One person can program many CNC lathes and then
supervise, sometimes, the need to change the tool only occasionally.
