CNC machining custom in the manufacturing process should pay special attention to many issues, such as large and medium-sized machinery factory production safety regulations, large and medium-sized machinery factory production process technical specifications, strictly enforced technical standards and requirements, etc.
1. When the commodity workpiece is too high, different specifications of the knife should be selected for roughening, and then use the knife to remove the remaining material in the corner.
2. The strong material strength should be selected for reverse milling production and processing; the low material strength should be selected for smooth milling production and processing; the finishing process should be selected for reverse milling production and processing, and the finishing process should be selected for smooth milling production and processing.
3. Mechanical parts processing clamping method should be scientific selection of fixed benchmark and clamping method. When we select the fixed benchmark, so that we should follow the "benchmark unity" and "benchmark overlap" 2 basic guidelines.
4. In determining the goods on the table workpiece, must consider the production of processing around, CNC tool specifications and rigidity of the impact on the production and processing of product quality.
5. The fixture selected in machining manufacturing should try to choose the fixture assembled by the actual parts, and can be adjusted to reasonably and effectively reduce the production preparation cycle.
6. The production and processing of all surfaces should be carried out in fixed fixtures as far as possible. Therefore, it is necessary for the precision parts processing plant to choose a fixture method that facilitates the production and processing of each surface of the commodity workpiece.
