Longmen milling machine body casting

When producing the casting of the gantry milling machine body, it is divided into two sections for casting. For rough machining, it can also be done in two stages. However, for precision machining, they can be connected together and processed as a whole using our factory's 3.2 * 16 meter gantry planer. This improves the overall straightness of the 16 meter bed and the machining accuracy of the machine bed.

Resin sand molds have good rigidity, and in the early stage of casting, it is possible to utilize the graphitization expansion, shrinkage, and porosity defects during the solidification process of cast iron to achieve low riser and no riser casting of gray cast iron and ductile iron parts.

Large molds such as Longmen milling machine body castings have significant advantages over traditional sand molds. They not only save expensive wood mold costs, but are also easy to operate, shorten production cycles, improve production efficiency, and have advantages such as small size, small machining allowance, and good surface quality.

The casting material of the Longmen milling machine body is delicate boring machine columns, with a ratio of gray cast iron HT200-HT300 and tensile and bending strength, making your purchase worry free.

The popular heat treatment process reduces the stress and deformation of castings to a minimum. The usage tends to be stable.
