Abstract
A machine tool includes a table, a main shaft, and an electric heating piece. The table includes an upright post and a main shaft support element connected to the upright post. The main shaft is rotatably disposed at the main shaft support element of the table. The electric heating piece is disposed at the main shaft support element of the table and positioned on a side of the main shaft, wherein the side of the main shaft manifests a lower thermal deformation level. The regulation of the electric heating piece minimizes the nonlinear thermal deformation of the main shaft, thereby enhancing processing precision.
