High-efficiency deep hole turning and boring machine and deep hole machining method thereof

Abstract

The invention discloses a high-efficiency deep hole turning and boring machine and a deep hole machining method thereof. The high-efficiency deep hole turning and boring machine comprises a machine bed, a headstock, a turning device, an oil feeder, a boring device, a control system and a cooling liquid system; the oil feeder is mounted at the middle part of the machine bed; a conical seat sleeve is arranged at the front end of the oil feeder; the conical seat sleeve is supported in a housing of the oil feeder through a bearing; a shaft seal is arranged at the inner end of the oil feeder to prevent the cooling liquid from flowing out; an anti-splash cover which can be turned over is arranged outside; and the conical seat sleeve presents a 3-5-degree conical surface. The oil feeder can be equipped with a center and a boring cutter guide sleeve, so that the machining of an outer circle of and the boring of a deep hole can be completed on one machine bed; and with the arrangement of a bracket, a central bracket function is provided, so that the straightness precision of boring and the multi-purpose effect and the effects of convenient and efficient machining are ensured.

Description

technical field [0001] The invention belongs to the technical field of deep and long hole pipe workpiece processing, and in particular relates to a high-efficiency deep hole turning and boring machine and a method for processing deep holes. Background technique [0002] At present, deep hole boring and cylindrical machining for long pipe workpieces are generally processed on two machine tools: deep hole boring machine and lathe; due to the difficulty of clamping and positioning, the straightness of inner hole processing and The coaxiality of the outer circle is difficult to guarantee, and the processing accuracy requirements cannot be met. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency deep hole turning and boring machine and its method for processing deep holes, so as to solve the unfavorable situation that the workpiece is difficult to be mounted on the same axis in the existing boring deep hole processing, and...
