Technical requirements for surface finishing of castings

Reasonable selection of cast iron T slotted plate equipment. Rough machining is mainly to cut off most of the machining allowance of the cast iron inspection table, which does not require high machining accuracy. Therefore, rough machining should be carried out on a machine tool with high power and low precision, and a high-precision machine tool is required for finishing. The use of different rough and fine processing methods can give full play to the production capacity of the equipment and extend the service life of the machine.


Cast iron platform manufacturers separate rough machining and finishing to ensure the machining accuracy of the cast iron inspection platform. Rough machining, large cutting volume, large cutting force, large clamping force, large heat generation, obvious surface hardening, and large internal stress of the workpiece. If rough machining is performed continuously, the parts after finishing will lose accuracy quickly due to the redistribution of stress. For some parts that have certain requirements for machining accuracy. Before roughing and finishing, use low-temperature annealing or timely treatment to eliminate internal stress.

The cast iron inspection station usually arranges the heat treatment process during processing. To improve the cutting performance of metals, such as annealing, normalizing, quenching and tempering, etc. It is usually arranged before processing. In order to eliminate internal stress, such as aging, quenching and tempering, etc., it is generally arranged before roughing and finishing. Improve the mechanical properties of parts, such as carburizing, quenching, tempering, etc., usually arranged after processing. If the deformation after heat treatment is large, a processing procedure (fine grinding) must be arranged.


After the casting inspection platform passes the inspection, the cast iron platform manufacturer inspects its products and issues a certificate of conformity; the product certificate should have a standard number and a product number. The hardness range of the casting inspection working surface is HB170-220 or 187-255. The casting inspection platform has been widely used in the printing industry, machining, bridges, ships, petrochemicals, textile machinery, printing and dyeing, printing and dyeing, ships, petrochemicals, mechanical processing and other fields. The casting inspection platform is mainly used for marking, measuring, riveting, mold processing, mold processing, and can also be used as a mechanical test bench.
