Arrangement principle of CNC processing sequence
The processing sequence shall be arranged according to the structure of the parts and the condition of the blanks, as well as the need for positioning and clamping, with the focus on ensuring that the rigidity of the workpiece is not damaged.
Generally, the sequence shall follow the following principles:
- The CNC processing of the previous process shall not affect the positioning and clamping of the next process, and the general machine tool processing process shall also be considered comprehensively.
- The internal shape and cavity processing procedure shall be carried out first, and then the external shape processing procedure shall be carried out.
- It is better to connect the CNC machining processes with the same positioning, clamping method or the same tool to reduce the number of repeated positioning, tool change and moving the pressing plate.
- For multiple processes carried out in the same installation, the process with little damage to the rigidity of the workpiece shall be arranged first.
Classification of CNC hardware surface processing
What are the common types of metal surface processing? According to the summary of our production experience for many years, it can be divided into several common processing methods: metal painting processing, electroplating, surface polishing processing and metal corrosion.
- Spray painting processing: now the hardware factory adopts spray painting processing when producing relatively large hardware products. Through spray painting processing, the hardware can be prevented from rusting, such as daily necessities, electrical enclosures, box type handicrafts, etc
- Electroplating: electroplating is also one of the most widely used processing technologies for hardware processing. Through modern process technology, the surface of hardware parts is electroplated to ensure that the products will not be mildewed and embroidered under long-term use. Common electroplating processes include screws, stamping parts, battery pieces, car parts, trinkets, etc,
- Surface polishing: surface polishing is generally a long-term method used in daily necessities. For example, we produce a comb, which is a metal part made by stamping. Then the edges and corners of the punched comb are very sharp. We need to polish the sharp parts of the edges and corners into a smooth face, so that the human body will not be damaged in the process of application.
The above are several common ways of metal surface processing.
