Furthermore, the non-parallelism of any two adjacent adsorption mounting surfaces in the six adsorption mounting surfaces is less than or equal to 1 micron, and the non-parallelism of any two opposite adsorption mounting surfaces is less than or equal to 1 micron.
A grinding method of a high-precision tool setting gauge is based on the grinding clamp of the high-precision tool setting gauge, and comprises the following specific steps:
firstly, fixing the tool setting gauge in a mounting hole of one rectangular plate;
secondly, adsorbing an adsorption mounting surface of a grinding clamp opposite to a tool setting surface to be ground of the tool setting gauge at present onto a bed surface with electromagnetic attraction of a grinding machine, and further carrying out precise grinding processing on the tool setting surface to be ground of the multi-head tool setting gauge at present;
thirdly, after the tool setting surface in the second step is ground, taking down the grinding fixture from the grinding machine, and then installing an adsorption installation surface of the grinding fixture opposite to another tool setting surface to be ground of the multi-head tool setting instrument on the grinding machine so as to precisely grind the tool setting surface of the multi-head tool setting instrument;

Has the advantages that: (1) according to the tool setting device, the tool setting gauge is clamped once, and the adsorption mounting surface on the grinding clamp, which is opposite to the tool setting surface to be ground at present, is adsorbed to the bed surface of the grinding machine in sequence, so that the precise grinding of at most five tool setting surfaces of the tool setting gauge can be efficiently completed; the grinding fixture can be used for grinding only by controlling the parallelism of the adsorption mounting surface and the tool setting surface of the grinding fixture, so that the grinding machining becomes very simple, the tool setting precision of the tool setting gauge can be greatly improved, and the production cost of the tool setting gauge is reduced.
(2) Because the non-perpendicularity of any two adjacent adsorption installation surfaces in the six adsorption installation surfaces of the grinding clamp is less than or equal to 1 micron, and the non-parallelism of any two opposite adsorption installation surfaces is less than or equal to 1 micron; therefore, the grinding tool setting surface of the grinding fixture can ensure that the non-parallelism between the tool setting instrument mounting surface and the tool setting surface is less than or equal to 1 micron, and the non-verticality between each pair of tool surfaces is less than or equal to 1 micron for the tool setting instrument above one tool setting surface.
