Problems solved by technology

[0002] The current lathes are only suitable for the processing of small workpieces, but when processing large workpieces of 15-100 meters, there is no corresponding processing equipment, resulting in the deformation of the guide rail due to the large gravity of the large workpiece when processing large parts. Unable to meet the customer's precision requirements for large parts, only rough machining can be carried out, which makes it difficult to process some special equipment parts

Abstract

The invention discloses a machine tool capable of machining large-sized workpieces and a use method of the machine tool. The machine tool comprises a base and a control box. A motor is mounted on oneside of the base, and a first belt wheel is mounted on a rotor of the motor. The first belt wheel is in transmission connection with a second belt wheel at one end of a transmission shaft through a triangular belt, and a tightening disc is mounted at the other end of the transmission shaft. A stepping motor is mounted at the other end of the base, and a workpiece supporting device is mounted between the stepping motor and the tightening disc. A cutting and feeding device is mounted on the front side of the base. According to the machine tool capable of machining the large-sized workpieces andthe use method of the machine tool, the machine tool can complete some workpieces with special requirements, especially some workpieces incapable of being completely on common machine tools, the difficulty that the huge workpieces cannot be machined can be overcome by the machine tool, and the difficulty in special equipment requirements is solved.

Description

technical field [0001] The invention relates to the technical field of lathes, in particular to a lathe capable of processing large workpieces and a use method thereof. Background technique [0002] The current lathes are only suitable for the processing of small workpieces, but when processing large workpieces of 15-100 meters, there is no corresponding processing equipment, resulting in the deformation of the guide rail due to the large gravity of the large workpiece when processing large parts. Unable to meet the customer's precision requirements for large parts, only rough machining can be carried out, which makes it difficult to process some special equipment parts. [0003] Therefore, it is necessary to provide a lathe that can process large workpieces and has good machining accuracy. Contents of the invention [0004] The object of the present invention is to provide a lathe capable of processing large workpieces and its use method, in order to solve the problems r...
