Method of manufacturing index device of machine tool

摘要

A method of manufacturing an index device of a machine tool includes providing a jig having an outer periphery of the same outer diameter as an outer diameter of a motor for driving the index device, inserting the jig into a casing configured to house the motor for driving the index device prior to setting the motor into the casing, filling a material with higher thermal conductivity than the air into gap space created between the casing and the outer periphery of the jig through an opening provided in the casing; removing the jig from the casing when the material filled in the gap space becomes solidified; and setting the motor into the casing with the jig removed therefrom.

1. A method of manufacturing an index device of a machine tool, the method comprising:
providing a jig having an outer periphery of the same outer diameter as an outer diameter of a motor for driving the index device; prior to setting the motor into a casing configured to house the motor, inserting the jig into the casing; filling, through an opening provided in the casing, a material with higher thermal conductivity than the air into a gap space created between the casing and the outer periphery of the jig; removing the jig from the casing when the material filled in the gap space becomes solidified; and setting the motor into the casing after said removing the jig from the casing.
