MW1420 universal cylinder grinder machine

 

Features:

 

 

The M14 series universal cylindrical grinders are one of the most important products . We started our career by manufacturing the cylindrical grinders. For these years we have supplied many high quality cylindrical grinders for domestic and abroad market.

 

 

 M14series type universal cylindrical grinding machines are used for grinding external or internal surfaces of rotary work-pieces of cylinder and taperworkpiece in almost every country all over the world because of the high quality with competitive price.

 

 

 

The longitudinal movement of the worktable is driven by hydraulic or by hand wheel. The worktable can rotate to a certain degree so as to be suitable for grinding taper. 

 

 

 

 The wheel head cross feed is driven by hydraulic, which realizes automatic periodical feed and rapid feed. It can also do rough and fine feed through hand wheel.

About the Cross Guideway, we choose the linear guieway, so that to make the MW1420 more efficient.

 

 

About the head stock, we adopt the coverter to control the headstock rotating speed. We put the controller on the control panel to make the operation much easier.
