High-precision small digital controlled lathe

Abstract

The invention relates to a high-precision small digital controlled lathe. The high-precision small digital controlled lathe comprises a main shaft power mechanism 1, a movable tailstock 2, a sliding table 3 and a knife rest 4, wherein coordination and cooperation of a high-strength bicylinder guide rail and a high-precision ball screw are adopted for the X-axis and Y-axis feeding part of the cross-shaped sliding table, so that friction resistance between the guide rail part and the sliding table is reduced, and meanwhile, the thermal deformation of the guide rail is greatly lowered; therefore the guide rail has higher guiding precision; the moving is more stable and high-efficient; and the machining precision of the lathe is improved, and the service life of the lathe is prolonged. Isosceles trapezoid design is adopted for the base of the lathe, so that the integral stability and shock resistance are effectively improved; screw sliding table feeding is adopted for the knife rest table of the lathe; and angle-rotatable dial display design is adopted under the knife rest, so that cutting, feeding and tool setting are more precise and high-efficient.

Description

technical field [0001] The invention relates to a high-precision small numerically controlled lathe, which belongs to the field of small mechanical processing equipment. Background technique [0002] Small CNC lathes are CNC lathes with small dimensions. This type of CNC lathe is mainly used for processing small-sized high-precision workpieces and mass production of small workpieces. It is widely used in military enterprises, electronic appliances, machinery manufacturing, aviation, etc. Aerospace and other fields. [0003] The guide rails of ordinary small CNC lathes usually adopt dovetail groove structure, and the iron chips are easy to accumulate in the chute during cutting, which increases the friction resistance with the slide table and reduces the processing efficiency. The contact area between the slide table and the guide rail is large, and the long The thermal deformation of the guide rail is easy to occur under long-term work. The overall volume of the lathe is sm...

Problems solved by technology

[0003] The guide rails of ordinary small CNC lathes usually adopt dovetail groove structure, and the iron chips are easy to accumulate in the chute during cutting, which increases the friction resistance with the slide table and reduces the processing efficiency. The contact area between the slide table and the guide rail is large, and the long Thermal deformation of the guide rail is easy to occur under long-term work. The overall volume of the lathe is small, and the cutting vibration generated during machining and cutting makes it difficult to ensure the stability of the center of gravity, which affects the accuracy of the processed workpiece.
