How To Deal with Chips in Milling And Turning Composite Machine Tools

In the process of turning milling composite machining, chip processing requires precise control.
Good chip management not only ensures processing efficiency, but also extends equipment life and improves workpiece quality.
In the face of the diverse chips generated by milling and turning composite processing, it is necessary to establish a systematic processing plan.

The recognition of chip morphology is the first step in processing.
The continuous strip-shaped chips generated by turning have completely different characteristics from the fragmented chips generated by milling.
When processing aluminum alloys, it is necessary to prevent the generation of excessively long winding chips to avoid damaging the surface of the workpiece.
By adjusting cutting parameters and tool geometry angles, the fracture effect of chips can be actively controlled.

The optimization of the coolant system is crucial for chip processing.
High pressure cooling (70-100 bar) can effectively crush chips and quickly flush them out of the machining area.
For deep cavity machining or difficult chip removal conditions, directional cooling technology can be used to accurately guide the coolant to the cutting edge.
Regularly cleaning the sediment in the coolant tank and keeping the filtration system unobstructed are the basic conditions for maintaining stable chip discharge.

Adjusting processing strategies can often achieve twice the result with half the effort.
Reasonably arrange the cutting path to allow the chips to naturally flow towards the chip discharge port;
Adopting variable parameter cutting, changing the feed rate at different processing stages to optimize chip morphology.
The flexible application of these process techniques can significantly improve the chip removal effect.

In practical operation, the experience and vigilance of operators are equally important.
Regularly inspect the chip removal situation of equipment, promptly detect and remove abnormal chip accumulation;
Record the chip status under different materials and processes, and accumulate valuable on-site data;
Keep the work area clean and orderly, creating a good environment for chip processing.
These seemingly simple work habits are often key factors in ensuring long-term stable production.

The chip processing of milling and turning composite machining is not an optimization of a single link, but requires full process collaboration from process planning, equipment configuration, tool selection to operation and maintenance.
Good chip control is not only to maintain cleanliness on site, but also an important measure to ensure machining safety, improve tool life, and ensure workpiece quality.
