Advantages and features of the turning and milling combination on a machine tool
1.Shortening the product manufacturing process chain and improving the production efficiency.
A lot of types of special cutters can be installed on the CNC turning and milling combination center. With a new cutter arrangement, reduced cutter changing time and increased machining efficiency, the turning and milling combination center can achieve all or most machining processes completed with just one-time setup, greatly shortening the product manufacturing process chain. This reduces not only the auxiliary production time caused by setup change but also the tooling fixture manufacturing cycle and the waiting time, which can significantly improve production efficiency.
As to machining efficiency, the new turning and milling combination center can have more special machining cutters equipped and arranged in a way totally different from the traditional CNC machining machinery in the past. This can both reduce cutter changing time and increase machining efficiency in a good way. The turning and milling combination center can achieve all or most machining processes completed with just one-time setup, greatly shortening the product manufacturing process chain.
2.Reducing the times of setup and improving machining precision.
ewer times of setup decrease or avoid the error accumulation due to positioning datum change. Besides, nowadays most of the turning and milling combination devices have the online testing function which can achieve in-place testing and precision control for key data in the manufacturing process, so as to improve product machining accuracy. High-strength integrated design of the machine tool body leads to better gravity machining capabilities for the materials difficult to machine. This turning and milling combination machine tool is quipped with an automatic feeding device for continuous automatic feeding, and the assembly line work of a single machine tool can be basically achieved.
The cutting speed can break up into the workpiece’s rotational speed and the cutter’s rotating speed. Based on mechanical characteristics, increasing the cutter’s rotating speed and decreasing the workpiece’s rotational speed can also achieve the same machining effects. This is especially effective for the machining of large forging blanks, because its speed decrease can eliminate the vibration or the periodic radial cutting force change due to workpiece decentration, guaranteeing stable workpiece cutting and reducing workpiece machining errors.
When a workpiece is being machined on the turning and milling combination machine tool, its low rotation speed can effectively decrease its centrifugal force to avoid deformation, which is good for machining accuracy improvement. During turning and milling, a larger longitudinal feed can also lead to accurate cutting, with surface roughness effectively guaranteed. The turning and milling combination machine tool can achieve workpiece machining in various ways such as turning, milling, drilling and boring, and multiple machining jobs can be completed for a workpiece with just one-time setup while guaranteeing machining accuracy.
3.Reducing floor space and decreasing production costs.
The compact and beautiful appearance design not only improves the space usage but also makes maintenance and repair easier, for the purpose of maximum customer satisfaction. Although a single turning and milling combination device has a higher price, overall fixed asset investments, production operations and management costs can be reduced effectively because of a shortened manufacturing process chain, fewer devices required, as well as decreased number of tooling fixtures, workshop floor space and device maintenance costs.
Additionally, it is obvious that the turning and milling combination machine tool can save a lot of production costs. Its compact design of appearances improves the space usage and makes maintenance more convenient. Although presently a single turning and milling combination device has a higher price, the operation and management costs for production can be well controlled because the expenses of equipment and its maintenance required for the manufacturing process is reduced.
In summary, according to the drawing and customer requirement information as well as final communication with the customer, this custom machining aluminum part has a very complex structure and needs the turning and milling combination, so it is right to choose this CNC machining method. Besides, the part to be machined this time is a shaft part which is made of light aluminum alloy. When installed on the remote control racing car, it is partially exposed. We carried out surface treatment for this machining aluminum part based on this point, and the customer was very satisfied with the effects of the finished product.
