Deciphering the casting process of machine tool castings

The manufacturing process of machine tool castings usually includes the following steps:

Design and mold manufacturing: First, design the casting to determine the shape, size and material of the casting. The mold used to produce the casting is then made, usually using a sand mold, a metal mold, or a permanent mold.

Melting metal: Select appropriate metal materials, such as iron, aluminum, brass, etc., and heat them to the melting point to form molten metal.

Prepare the sand mold: Use a mold to pour molten metal into the sand mold. A sand mold can be a dedicated mold for a single casting or a continuous mold for continuous casting.

Pouring and Solidification: Molten metal is poured into a sand mold, filling the entire cavity. After the metal cools and solidifies, the initial shape of the casting is obtained.

Mold separation: After cooling and solidification, the mold is disassembled from the casting to obtain the initial casting.

Remove burrs and defects: Deburr and trim the initial castings to remove possible defects such as sand cores, pores, inclusions, etc. to ensure the quality of the castings.

Finishing: Further processing operations such as milling, drilling, threading, etc. are performed on the casting as needed to meet the requirements of the final product.

Surface treatment: Perform necessary surface treatment on castings, such as polishing, painting, plating, etc., to improve appearance quality and corrosion resistance.

Inspection and quality control: Conduct various inspections and tests on castings, such as dimensional measurement, material analysis, non-destructive testing, etc., to ensure that the castings meet design requirements and quality standards.

Final product: After the above steps, a machine tool casting that meets the requirements is obtained, which can be assembled and put into use.

It should be noted that the specific steps and methods of the machine tool casting manufacturing process may vary depending on the shape, size, material and production equipment of the casting.
