Milling process is essentially a kind of intermittent processing process. This causes the temperature at the cutting edge to fluctuate between high temperature (about 1000 \u2103) and low temperature.<\/p>\n\n\n\n

Effect of cutting fluid<\/h2>\n\n\n\n

When the cutting edge cuts in and cuts out, the temperature change will increase. As a result, the cutting edge is subject to thermal shock and periodic stresses, which may result in cracks and, in the worst case, premature end of tool life.<\/p>\n\n\n\n

The higher the temperature of the cutting area, the less suitable the cutting fluid is.<\/p>\n\n\n\n

In the finishing process, the use of cutting fluid will not shorten the tool life as much as in rough machining due to the reduced heat generated.<\/p>\n\n\n\n

dry milling<\/h2>\n\n\n\n

Dry milling can prolong the life of cutting edge. The temperature does change, but it will remain within the design range of cemented carbide materials.<\/p>\n\n\n\n

Rough milling should always be carried out without cutting fluid.<\/p>\n\n\n\n

wet milling with cutting fluid<\/h2>\n\n\n\n

There are some exceptions to the use of cutting fluid:<\/p>\n\n\n\n

1) Finish machining of stainless steel and aluminum alloys – used to prevent metal particles from sticking to the surface structure<\/p>\n\n\n\n

2) Milling superalloys at low cutting speeds – for lubrication and cooling of parts<\/p>\n\n\n\n

3) Cast iron milling, used to wet and remove dust to protect the environment and health and ensure the accuracy of parts<\/p>\n\n\n\n

4) Milling of thin wall parts to prevent geometric deformation<\/p>\n\n\n\n

5) When machining deep cavity, micro lubrication system (i.e. compressed air containing a small amount of special oil) can be used to assist chip removal<\/p>\n\n\n\n

In the micro lubrication system, the “oil mist” is only a few milliliters of oil per hour, and is discharged through the ordinary filtering ventilation system.<\/p>\n\n\n\n

If wet milling must be carried out, a sufficient amount of cutting fluid should be used.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
