Designed to check the positioning of CNC Machines, Machining Centers and Coordinate Measuring Machines, which is the optimum quality tool to improve the fixing accuracy by error compensation method. For calibrating various application measurements including dial calipers, digital calipers and height gauges and the like. Gauge blocks arrangement can be designed according to customers' needs. Available with stainless steel gauge blocks, carbide-tipped gauge blocks and ceramic gauge blocks. The steel type is the most economical, but it should pay attention to avoid rust. Carbide-tipped gauge blocks (conductivity) are ideal for checking the accuracy of linear cutting machines. The ceramic one is free from rust and abrasion.
