Introduction to machining process of machine tool bed

Introduction to machining process of machine tool bed: process characteristics of finishing, rough machining and finishing

finishing process of machine tool bed castings

cut less machining allowance from the surface of Machinists who have undergone rough machining mechanical test of copper plastic composite plate in Jinan era, The process that enables the workpiece to achieve high machining accuracy and surface quality PHA has gas barrier property (CO2 and O2 can only be slowly penetrated) is the finishing process. If the workpiece surface has no special high requirements, finishing is often used as the final processing

the finishing process of machine tool bed castings

it is to cut a small amount of machining allowance from the surface of the finished workpiece to obtain high machining accuracy and small surface roughness value. Grinding, honing, superfinishing, polishing and other methods belong to the finishing process

rough machining process of machine tool bed castings

the process of cutting most of the machining allowance from the workpiece to make its shape and size close to the requirements of the finished product is the rough machining process. Its machining accuracy is low and the surface roughness value is large. It is generally used for the final machining of low requirements or non matching surfaces, and also as the pre machining of finishing

the importance of tempering of machine tool bed castings

Why do machine tool bed castings need tempering treatment: steel is the most widely used material in the mechanical industry, and its microstructure is complex, which can be controlled by heat treatment, so the heat treatment of steel is the main content of metal heat treatment. In order to make machine tool castings have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment process is essential. In addition, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties. Integral heat treatment is a metal heat treatment process that heats the cast iron flat plate, cast iron bending plate or machine tool bed castings as a whole, and then cools them at an appropriate speed to change the overall mechanical properties of cast iron platform, flat plate, cast iron bending plate or machine tool bed castings

heat treatment of machine tool castings is an important process link in machine manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece selected and expanded according to the market situation in the later stage, but endows or improves the service performance of the workpiece by changing the microstructure inside the workpiece or the chemical composition of the cast iron platform and machine tool surface. Its characteristic is to improve the internal quality of the workpiece. (end)
