With the adjustment of the industrial development, also is to have an increase of the relative to the requirement of industrial products, at the same time the development of heat pump technology is also in constant, at the same time, the production efficiency of heat pump and related industries manufacturing quality put forward higher request, in order to achieve high temperature oil pump cavity and its related parts of the high speed machining, machine tool needs to have the following features:
1. Because the high temperature oil pump is developing to large-scale direction, a few tons to dozens of tons of high temperature oil pump is very common, so the machine tool workbench can bear large weight, which requires the equipment must have large bearing and high rigidity characteristics, but also must have large enough table size and work stroke to adapt to it.
2. High speed and high power high speed machining is the developing direction. High speed milling has shown great superiority in high temperature oil pump machining.
3. High temperature oil pump cavity is mostly composed of complex space six curved surfaces and grooves, and many high temperature oil pumps have deep hole cavity.
