We Should Improve Precisiion Machining

/in /by

Ultra precision machining technology was developed and perfected in 1960s. It has become the key manufacturing technology of high technology products. Over the past 20 years, ultra precision machining has not only entered into every field of the national economy, but also has shifted from single piece production to large-scale production. It can be met, with the emergence of new products, the application of ultra precision machining will be further expanded.

Now the precision machining technology we have is in a lot of practice, take advantage of an opportunity, we continuously improve the precision and density. There is still a long way to go for Precision Machining in our country.

Importance of Maintainking CNC Turning?

/in /by

CNC Turning is a high precision and high efficiency automated machine tools. Equipped with multi-station turret or power turret, it has a wide range of processing technology performance and can processed various complex parts and kinds of compensation functions. CNC lathe plays a good economic results in the mass production of complex spare parts.

In order to ensure the work accuracy of lathe bed CNC lathe and prolong its service life, it is necessary to carry out reasonable maintenance work timely for the CNC lathe. Lathe maintenance is good or bad, affect the workpiece processing quality and production efficiency directly. After the CNC lathe running 500h later, it need A class maintenance. Slant bed CNC lathe maintenance work five priority to operators, maintenance workers to cooperate. When Maintenance, you must cut off the power firstly, and then maintain it according to the contents and requirements.

Requirements for Fixture in CNC Machiining

/in /by

CNC Machining characteristics of the fixture put forward two basic requirements: first, to ensure that the coordinates of the fixture and the direction of the machine tool coordinate direction are relatively fixed. The second requirement is to coordinate parts and machine tool coordinate system dimensional relationship. In addition, we should consider the following points:

1. When the parts processing is not large, we should try to use modular fixture, adjustable fixture, and other general fixture to shorten the production preparation time and save production costs.

2. In the mass production, you can only consider the use of special fixture, and strive for simple structure.

3. The loading and unloading of parts should be fast, convenient and reliable to shorten the stop time of machine tools.

4. Fixture parts should not prevent the machine tool on the surface of each part of the processing, that is, the fixture to open, and its positioning, clamping elements can not affect the processing of the cutter.
