For efficient machining center to process metal material cutting, the raw material to be processed, cutting special tools, cutting standards are three major factors. Such decisions determine the processing time, tool life and processing quality. The economic development of reasonable processing methods must be effective selection of cutting standards.
Machining center processing cutting use of effective selection
Machining center processing cutting standards of the three elements.
Cutting speed, feed and depth of cut immediately cause damage to the tool. With the increase in cutting speed, the sharp knife temperature will rise, which will cause mechanical equipment, organic chemical, thermal wear. A 20% increase in cutting speed, CNC precision machining, tool life will be reduced by 1/2.
The standard of tool walking and tool back edge wear association is caused in a very small range. However, high feeds and elevated cutting temperatures result in high trailing edge wear. It is less harmful to the tool than the cutting speed. The harm of depth of cut to the tool although there is no cutting speed and feed is large, but in the fine depth of cut cutting, the raw material being cut causes a hard bottoming layer, which will harm the tool life as well.
Customers should select the applied cutting speed according to the raw material to be processed, strength, cutting situation, type of raw material, feed, depth of cut, etc. The most suitable machining standard is selected on the basis of such elements. There is a standard, smooth wear to achieve the life of the standard is considered idealized.
I do not know, in the specific work, the selection of the tool life and tool wear, being processed specifications shift, process performance, cutting noise, processing heat and other related. CNC machining for stainless steel plates and heat-resistant alloys and other difficult-to-machine raw materials, the ability to choose coolant or the use of good rigidity of the edge.
