Reference base for inspection, tool making, gauging, spotting marking and layout operations, supported on suitable stands. 
ccording to standard JB/T7974-99 (and can produce according to customer's request)
Accuracy: Grade 1 to Grade 3 Grade: 1-3
Material: Hardness Hardness HT200-300
Rate belongs to cast iron platform series, mainly used for ground boring and milling machine, CNC boring and milling machine, general milling planer, CNC gantry milling machine, main effect is to use the platform to be processing parts of the operation, the platform itself have T trough, etc.; Platform using anchor to reinforce installation, deb ing and so on. Test plate, crossed platform, combined platform, T slot platform material for: HT200-300. The working surface hardness is HB170 ~ 210. After two aging treatment (artificial aging and natural aging 2 ~ 3 years). The accuracy of the product is stable and good abrasion resistance. Cast iron plate, platform is mechanical parts inspection plane, parallel degree, vertical degree, Angle, straightness and shape measurement of position tolerances.

Specifications can be made or agreed production and processing according to buyer's drawings
