1. The type, model and actual use of the machine tool. 2. According to the requirements of the machine tool instruction manual, formulate and establish the necessary period. 3. Grading maintenance system. Mechanical system—mainly includes: spindle unit, guide rail, additional rotary table, automatic tool changer, large support structure casting, hydraulic system, lubrication system, air pressure system, cooling system: cooling pump, water pipe, water storage tank, cutting fluid.
Moreover, computer-aided simulation technology of the cutting process has also appeared, which is very meaningful for predicting tool temperature, stress, and prolonging tool life. The applications of casting, die, hot press and injection moulding represent an expanded range of high speed cutting applications for cast iron, cast steel and alloy steel.
In the die and casting mould making in the leading industrial countries, most of the development time is spent on machining and polishing operations. The machining and polishing of the die or casting mold account for about 2/3 of the entire processing cost, and high-speed milling can be used to shorten the development cycle and reduce the processing cost.
