Product Description

Machine Introduction

Follow the Dynamic Lathe-Grinding Composite
Seamless switching between turning and grinding, an excellent choice for precision machining!

A sub-micron follow-up turning and grinding integrated compound grinding machine, which can realize integrated processing of various eccentric shafts, turning of various shafts and shaft sleeves, internal and external cylindrical grinding, taper grinding, thread grinding, groove grinding, follow-up forming contour grinding, etc.
 

Machine Features

Bed body: HT300A high-strength fine-baked casting, integrally cast bed body.

Permanent magnet synchronous motorized spindle: High-precision and high-rigidity built-in permanent magnet synchronous motorized spindle, A2-6 spindle specification.

Servo turntable: High-precision positioning 4-station servo turntable.

Inner circular grinding spindle: A high-speed inner circular grinding spindle with a maximum rotational speed of 36000 rpm.

External cylindrical grinding spindle: High-rigidity external cylindrical grinding spindle with a maximum speed of 4000 rpm.

NC intelligent tailstock: The sleeve is driven by hydraulic pressure to extend and retract, and the center point pressure is adjustable; the coaxiality of the tailstock can be finely adjusted at the micron level.

Grinding wheel dressing device: A wide range of dressing methods are available, including diamond pen dressing and high-speed roller dressing.
