The function of cutting fluid in CNC machining

The equipment of hardware machining manufacturers, whether it is lathes, milling machines or grinders, is inseparable from cutting fluids. Mastars uses CNC technology to make prototypings and mass production, providing customers with rapid prototyping services and high-precision parts production. CNC should be more and more widely used in today's industrial manufacturing services.

Cutting fluids can be divided into oil-based and water-based. It needs to be selected according to different equipment. For grinding machines, lathes, milling machines, and wire cutting, water-based cutting fluids should be selected, and oil-based cutting fluids should be selected for electrical discharge machining.

The cutting fluid should have good cooling, lubricating, anti-rust, degreasing cleaning, anti-corrosion functions, and easy to dilute and so on.

The first function is lubrication: the lubricating effect of metal cutting fluid in the cutting process can reduce the friction between the rake face of the tool and the chip, the flank face and the machined surface of the precision machined part, and form part of the lubricating film, so as to reduce cutting force, friction and power consumption, reduce the surface temperature and tool wear of the friction part between the tool and the workpiece blank, and improve the cutting performance of the workpiece material.

The second function is cooling: the cooling effect of the cutting fluid is to take the cutting heat away from the tool and the workpiece through the convection and vaporization between it and the tool (or grinding wheel), chip and workpiece, so it effectively reduce the cutting temperature, reduce the thermal deformation of workpiece and tool, maintain the hardness of the tool, and improve the machining precision and tool durability of precision mechanical parts.

The third function is cleaning: in the process of metal cutting, the cutting fluid is required to have a good cleaning effect, remove the generated chips, grinding chips, iron powder, oil stains and sand particles, prevent the contamination of the machine tool, the workpiece and the tool, so as to keep the cutting edge of the tool or grinding wheel sharp, so that it does not affect the cutting effect.
