Detailed Description:

The 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, It’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 plates’ stability and abrasion resistance. According to national standard metrological verification regulation, the accuracy class of plates are divided into “0”grade,“Ⅰ”grade,A“Ⅱ”grade,“Ⅲ”grade. And the plates can be machined on the working surface of plates.

The Cast Iron Surface Plate is the benchmark measuring tool which can be applied to testing, lineation, assembling, welding, installing and rivet welding for the work pieces and equipments.

The Cast Iron Surface Plate accessories have anchor bolts, anchor devices, levelling bolts, T-bolts, levelling pad iron, cover plate etc.

T-SLOT ACCURACY TO DIN 650

Tolerance on slot width H12.(Tolerance H7 or H8 on request)

Example:

A T-slot DIN 650-28 H12 has a nominal slot opening (a) of 28mm for bolt size M24(1”).

The T-slot height (H) according to the table below is 48mm.

(1 mm = 0.03937 inch, 1 inch = 25.4 mm)
