In the current CNC machining technology, the concept of high-speed cutting has been mentioned more and more. The CNC vertical machining center v850 has become a processing equipment suitable for high-speed cutting due to its unique spindle position and processing operation mode. So what is the difference between high-speed cutting and traditional cutting? What equipment conditions are needed to realize high-speed cutting?
The concept of high-speed cutting can actually be understood from the literal meaning, first of all, high speed is required. The high speed here refers to the high spindle speed (above 9000 rpm/min), and also refers to the greater limit of the feed rate. In addition, the acceleration time from the static state to the required speed after the rapid movement, rapid tool change, and spindle tool change are all It is a measure of high-speed cutting.
Regarding the applicability of high-speed cutting, in fact, not all processing procedures are suitable for high-speed cutting. It is necessary to select the corresponding reasonable processing parameters according to the different processing objects, the different hardness of the workpiece material, and the different shape of the workpiece after forming, instead of blindly pursuing high speed.
Especially in the process where the shape of the box-shaped workpiece is complicated and the tool diameter is small. Since the motion path of the tool is not a simple linear motion but a curve, even when there is a right-angle turn, the rationality of the process parameters is particularly important.
Machining goals that can be achieved by high-speed cutting
In most linear cutting processes, due to the small depth and thickness, but due to the high spindle speed and fast feed speed, the amount of metal removal per unit time is increased, and the processing efficiency is also improved. During processing, rough machining, semi-finishing and finishing can be integrated, all of which are completed on one machine tool, which reduces the number of machine tools and avoids errors in accuracy due to multiple clamping. The most important thing is that the processing time is short and the economic performance is good.
For workpieces made of non-ferrous metals, such as aluminum and aluminum alloys, especially thin-walled processing of aluminum, graphite and hardened molds, high-speed cutting technology has a wide range of applications, so it has become commonly used in CNC machining workshops. processing methods.
