1. It can maintain the best cutting state of the tool and improve the cutting conditions
During three-axis cutting, when the cutting tool moves to the top or the edge of the workpiece, the cutting state gradually deteriorates, and to maintain the best cutting state here, it is necessary to rotate the worktable, and the five-axis machining center can rotate the working strip to keep the tool in the best cutting state, and can also avoid the situation that the linear velocity of the center point of the ball nose milling cutter is 0, and obtain better surface quality.
2. Effectively avoid tool interference
Due to interference, the three-axis machining center cannot meet the process requirements, so it cannot process parts such as impellers, blades and integral blisks used in the aerospace field; The five-axis machining center can use shorter tools for machining, improve the rigidity of the system, reduce the number of tools, avoid the generation of special tools, and effectively avoid tool interference.
3. Reduce the number of clamping, and complete five-sided processing in one clamping
Five-axis machining centers can also reduce datum conversion and improve machining accuracy. In actual machining, only one clamping is required, and the machining accuracy is easier to guarantee. At the same time, due to the shortening of the process chain and the reduction of the number of equipment, the number of fixtures, workshop floor space and equipment maintenance costs of the five-axis machining center are also reduced.
4. Improve processing quality and efficiency
The five-axis machining center can use the tool side edge cutting, and the machining efficiency is higher.
5. Shorten the production process chain
The five-axis CNC machining center can be completely processed, which greatly shortens the production process chain and can simplify production management and planning scheduling.
6. Shorten the R&D cycle of new products
Some new product parts and forming molds are very complex in shape, and the precision requirements are also very high, so the five-axis CNC machining center with high flexibility, high precision, high integration and complete processing ability can well solve the accuracy and cycle problems of complex parts processing in the process of new product research and development, greatly shorten the research and development cycle, and improve the success rate of new products.
The above are the characteristics of the five-axis machining center, but compared with the ordinary machining center, the tool control, numerical control system, programming and post-processing of the five-axis machining center are also more complex, and the price is more expensive, and it is generally used in industries with high processing needs.
