Cast Iron Surface Plate By Cangzhou Zhongbo Heavy Industry Mechinery & Equipment Co., Ltd

These Cast Iron Surface Plate is called Working Platform(working plate),Worktable. The gross structure of Cast Iron Surface Plate (worktables) is divide into box type and rib type. The shape of working surface is rectangle,square and roundness. According to the precision machining,Ita s divided into finish plane and scraping.
There are V-Slots,T-Slots,U-Slots,dovetail slots,round holes,slotted holes etc.The material is HT200-300 etc,the working surface hardness is between HB160 and HB 210.
There are two tempering treatment (artificial annealing (seasoning):600 to 700 centigree,natural seasoning:2 to 3 years to keep the platesa stability and abrasion resistance.According to national standard metrological verification regulation regulation,the accuracy class of plates are divided into a 0a grade,a a a grade,a a a grade,a a ca grade.And the plates can be machined on the working surface of plates.
