PVA grinding stones are generally known as elastic grinding wheels. They are shaped as porous grinding wheels with high elasticity, using PVA (polyvinyl alcohol) as the bonding agent. Their polishing characteristics are that of a typical shedding type, which enables an excellent polish on finished surfaces when using an ultrafine grain. Grain sizes up to #10,000 can be used.
The PVA grinding wheel have the structure of sponge, it is bonded with Polyvinyl Alcohol . Grinding wheel have the characteristic of porosity and elasticity
Since the degree of elasticity can be controlled, customers' needs for precision-polish grinding wheels can be given
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.
Most of the Indian manufacturers have foreign technical collaborations.
The collaborators provide R&D support through product, process upgradation and manpower training
