Scope

JB/T 12668.1-2016 is the English-translated version of 超硬刀具数控电火花磨床第1部分：精度检验.

JB/T 12668.1-2016 is the first part of a recommended Chinese machinery industry standard on numerically controlled electrical discharge grinding machines for superhard cutting tools, and it is the part on accuracy testing.

It prescribes the geometric accuracy tests for the machine, the checks on positioning accuracy and repeatability of the NC axes, a machining test, and the tolerance values that go with each of these.

Its provisions are confined to the accuracy of the machine, which is verified before running tests or machine parameters are considered. It also names the main components of the machine and identifies the coordinate axes with reference to GB/T 19660-2005. It quotes GB/T 17421.1-1998 and GB/T 17421.2-2000.
