Precision mold must be done before processing machine tool operations
Nov 11, 2016

In the mode key mold machining process in order to reduce the error of thermal deformation of processing system must first fully cooled, reduced temperature rise; machine in a State of thermal equilibrium for processing for precision machining in the condition of constant temperature. Must be before processing all no-load operation for a period of time to preheat, after thermal equilibrium is reached, and then processed. Because the thermal deformation of machine tool on Machining accuracy of precision mould more influence. Due to the large volume and quality of the machine, from starting to heat up to the temperature is essentially the same, namely, thermal equilibrium State, takes a long time. Continued deformation of machine tool during the heating process, difficult to control processing of the workpiece.
