MODEL : GH-1 AND GH-2
PRECISION CYLINDRICAL GRINDING MACHINES [LIGHT SERIES]

These machines, For a wide range of applications. Capable of working to close tolerances are a positive as set in any tool room owing to their precision and case of operation .These machines are specially useful for jobs involving fine grinding of delicate workpieces calling for high degree of precision and superior Surface finish such as :

Machine Features:

These machines have special features like single swivel configuration and double swivel configuration which are shown below.

Wheel and work spindle:

Spindles for the wheelhead and workhead are made of EN –24 nickelchrome steel ,duly ground and lapped. The wheelhead spindle runs in white metal adjusting type bush bearings and the workhead spindle runs in gun metal adjustable type bush-bearings.

These special bush- bearings are de-signed in such a way that they can be collapsed on to the spindle with progressive scraping. This ensure a uniform ultrafine oil film clearance .Oil rings also ensure positive lubrication. Backlash on the wheelhead screw is effectively eliminated by spring load,the spring also holding the wheelhead down don the slideway.

Special features:

Workpiece accuracy is constantly maintained by the throw over lever in the hubs of the feed wheels through engaging expanding clutches which switch over from coarse to fine feeds. A high degree of swivel wheelheads which can be plunged at any desired angle or can be used to traverse – grind steep tapers.

Micro fine feed controls provide the machine with light and delicate feel necessary for fine grinding of small components.

Universal type construction:

The basic G-1, G-2 and GH-1, GH-2 Cylindrical Grinding Machines can be supplied with an interchangeable self-contained internal grinding head which can be mounted in place of the external wheelhead . Thus these become ‘Universal’ type machines ,capable of both external and internal cylindrical grinding.

They have a centre height of 90 mm. The distance between centres is 300 mm for G-1, G-2, GH-1 and GH-2.
