 products are chemically bonded and unlike vitrified or resinoid products. These are very soft and flexible. The structure of these wheels is like a natural sponge and has three dimensional pores.

Grades and sizes :

The product is available in 46 grit to 400 grit in green silicon carbide but we can supply any grit upto 1200 grit in silicon carbide or aluminium oxide. These are available as grinding wheels, mounted points, honing stones and blocks in size upto 260 mm in diameter. Bigger sizes can be manufactured on request.

Usage :

These products are mainly used for polishing applications like polishing of watch cases, audio and video heads, printing rolls, cylinders, compressor parts, surgical equipment, vehicle rims, tools and auto parts, dies & moulds etc. PVA products can polish any material ferrous or non-ferrous, metal or non-metal. Some examples are stainless steel, brass, steels, copper, aluminium, bronze, glass, stones etc. Besides polishing, these products can be used for burr removal, descaling, rust removing and for any such applications.One can achieve finishes as high as 0.03 micron on steel components. Basically a mirror finish can be easily obtained with these products.

Equipment :

No special machines are required to use PVA wheels. The whels can be used with all conventional machines like bench grinders, electric hand grinders, surface grinders, cylindrical grinders, tool and cutting grinders, etc. The wheel is flexible and hence can be easily dressed with conventional dressing tools or even by a used piece of a vitrified grinding wheels. It can be dressed to any desired shape easily. These products are used mainly for polishing and as such too much of material removal cannot be expected. For burr- removal coarse abrasives can be used

Limitations :

Due to its flexible nature the maximum operating speed is 25 mps

  • Wheels are hydrophilic in nature , hence absorbs moisture and stops cutting. No coolant is required.
  • Storage should be in polythene bags and at dry place. In cas of efficiency going down due to moisture absorption, the wheels can be dried in sun for an hour or so or can be dried in oven at 45 deg. C for about an hour for regaining its original properties.
  • For fine finished, some wax or a drop or two of oil can be applied to the cutting surface.
