rotary boring/tapping/cutting special machine

In recent years, China has continuously made corresponding changes and adjustments to the industry, and gradually established the stage of a planned economy, following the footsteps of the information age and market economy. With the rational allocation of resources worldwide, China's manufacturing industry has entered a new stage of development, but it has also made corresponding progress in industrial demand.

rotary boring/tapping/cutting special machine The precision, stiffness and thermal deformation of rotary boring/tapping/cutting special machine parts directly affect the machining quality. These effects are exacerbated by the fact that CNC lathes do not require manual adjustment during machining. At present, rotary boring/tapping/cutting special machine spindle has three main ways.

The front bracket consists of a double row short cylindrical roller bearing and a 60° contact double row radial thrust ball bearing. The rear bracket is fitted with a pair of radial thrust ball bearings. This structure greatly improves the overall rigidity of the spindle, can meet the requirements of strong chips, and is widely used in a variety of CNC lathes from small CNC lathe manufacturers. The front bearing uses high-precision double-row angular contact ball bearings, and the rear bearing uses single-row (or double-row) angular contact ball bearings. The equipment has excellent high speed performance, but small load capacity, so it is suitable for high speed, light load and fine CNC lathe spindle.

Double and single row tapered bearings are used for front and rear bearings respectively. This structure limits the high speed and accuracy of the spindle and is suitable for spindle of medium precision, low speed and heavy duty CNC lathes. Stepper motor and single chip microcomputer are used to transform simple rotary boring/tapping/cutting special machine composed of ordinary lathe feed system, but the cost is low, but the degree of automation and function are poor, and the turning accuracy is not high. Suitable for low demand rotating parts.

According to turning requirements, CNC lathes are specially planned and equipped with a universal CNC system. Numerical control system has powerful function, high degree of automation and high machining precision. Suitable for general turning parts. CNC lathes can control two axes at the same time, namely the X axis and the Z axis.
