We offer a complete product range of Super Finishing Stones and Wheels and Honing Stones

Super Finishing Stones And Wheels

As the name suggests these stones are used to achieve very high quality finishes. In certain cases it is an extension of honing operation.

We manufacture the widest range of super finishing stones for a vast number of applications. Super finishing stones are manufactured from high purity aluminium oxide and silicon carbide in grits ranging from 500 to 1200 as per FEPA standards. On special requests from our customers we can also supply super finishing stones in grits as per Japanese standards upto grit 6000. These can be supplied in any shape or size.

We have developed very special bonds for these products based on the applications, which combine a good rate of stock removal with a capacity to produce excellent finishes. on hardened steel components finishes as high as 0.01 microns can be obtained.

These stones are manufactured in vitrified bond, resin bond, rubber bond as well as flexible PVA bond and are recommended based on the application.

Application :

Our stones are specially manufactured for the following application.

Superfinishing the tracks of Ball Bearings (IR & OR)
Cylindrical bearings, Cylinder roller and taper bearings, angular and needle bearings
Finishing of rollers and shafts, piston pins etc.
Finishing of high pressure hydraulic cylinders & pistons
Finishing of ball bearing seats of cam shafts & crank shafts.
Finishing of shock absorber components.
Finishing of Textile and printing rolls.
Finishing of bearing shafts of rotary compressor and pumps

For super finishing of surface- plain & cup wheels are used for

Finishing of cylindrical & conical rollers
Engine nozzle pieces
Fuel injection pump cylinders
Video head drum shaft
Pump Impeller
Valve seats etc.

It is important to select the proper stone or wheel for your specific application. Our experts will help you to decide your requirements. The following basic information will be helpful in making the basic selection

Type of machine used and number of stations
Stone pressure and oscillation ( wheel speed in case of wheel)
RPM of job
Approximate time allowed for each operation like roughing stations and finishing stations
Material of the component and its hardness
Material removal desired
Initial finish before super finishing
Final finish required
Size of the stone and number of stones ( wheel shape & size)

Specifications of stones currently being used and the areas in which improvement is desired if any (stone/ wheel) can be mentioned

Besides conventional applications, these stones can be used for finishing or polishing on number of components, where a very high quality of surface finish is required. Kindly let us have your specific requirements and our staff will guide you to achieve the best results for your application. Although these are normally rectangular in shape but many special shapes are also being manufactured by us as per the requirements of the customer

Honing Stones,honing Stones

Honing stones are manufactured from high purity synthetic corundum (Aluminum Oxide) and Silicon Carbide. We manufacture vitrified bonded as well as Bakelite bonded, resin bonded, rubber bonded and PVA bonded honing stones depending on the special applications of our customers. We have developed special cool cutting bonds which provide high rate of stock removal with a good finish. This cuts the production costs and eliminates frequent dressing due to the self dressing property of our stones.

The grit range is from 20 to 400 as per FEPA standards and sizes are customised.
