5. Grinding Wheels
The art of producing high quality abrasive products consists in finding out the correct composition of raw materials,
combined with the correct production procedure for individual applications.
The raw materials used are Aluminum Oxide ( brown, pink, white & SA ) and Silicon Carbide ( black & green ).The most
important part of the grinding wheel is the vitrified bond which joins the grains.
We use various types of bonds specially developed for each operation of grinding and manufacture wheels upto 500mm in
diameter for centerless grinding ,surface grinding and cylindrical grinding. We have also developed special cool cutting
bonds for use on work pieces like drills, milling cutters ,saws, gears, thread grinding etc, where cutting quality & low heat
generation are specially important .
Special fine grit wheels for fine polishing on various materials before buffing ,have been developed by us . Our range of
these wheels are in grits 320 to 1200 as per FEPA standards.
Our range comprises of wheels for :
· Rough grinding
· Precision grinding
· Cutting of metal
· Cutting of ceramic
· Cutting of glass

10. INTERNAL GRINDING WHEELS
These are small grinding wheels which are used for grinding internal surfaces. We have developed very
special wheels for the following applications:
Grinding of inner and outer faces of Ball & Roller Bearings.
Grinding of Bores of inner rings.
Grinding of Hydraulic and Pneumatic cylinders.
Grinding of Connecting Rod ends in the automobile industry
Grinding of Gun Barrels.
Grinding of Gear bores, collets etc.
The applications mentioned call for high accuracy to the tune of microns. Conventional grinding wheels are
unable to give such accuracy due to their uneven wear while grinding. We have developed a special bond
system which gives the wheel, the most important property of shape retention. For grinding the tracks of ball
bearing races the wheels are sulphur treated to provide cool cutting even at very high speeds of 80 mps.
Mixed Aluminum Oxide wheels are manufactured to give properties lying in between the two extremes of
higher material removal and longer life.

14. PVA PRODUCTS
PVA 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 up
to 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 wheels 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 they absorb moisture and stop cutting. No coolant is required.
Storage should be in polythene bags and at a dry place. In case 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.

15. How to use
The wheels should be mounted
on the conventional machine.
The flanges should be 2/3 rd the
wheel diameter.
In case of mounted points,
conventional electric grinder can
be used. After mounting, the
wheels should be dressed to the
required shape and then some
wax or wax based compound or
oil can be applied to the wheels if
fine finish is required.
For burr-removal, descaling etc.,
nothing is to be applied. After
polishing the component with the
wheel, the same can be buffed
using a cloth wheel if mirror
finish is required.

16. RUBBER BONDED GRINDING WHEELS
Rubber bonded grinding wheels show different characteristics
compared to other grinding wheels.They are resilient and as strong
as others. These are suitable where coolant is used. The finish
obtained with them is high and rich. They can be used in precision
grinding, polishing and regulating.
Grinding :
Recommended for precision grinding of steel, 55 HRC and above , in cylindrical and centreless
operation under coolant conditions where in higher stock removal and polish are the criteria.
Cutting :
Starting fro the thinnest of cutting to deep plunge grooving of metals. They exhibit perfect
grinding and polishing in the component.
Polishing :
Wheels are flexible, imparting a high accurate finish in microns. The finish obtained under dry
conditions are free from scratches, chatter and score marks.
Regulating wheels :
Mainly for centreless machines. Their resilient character in plunge through feed and in form
grinding makes it a better product for such application.
Flute grinding :
These wheels are used for grinding flutes of drills and taps. These wheels have high material
removal characteristics.

Shapes

26. SHAPE :
All shapes and sizes available as per FEPA standards. Special shapes and sizes can also be
supplied as per customer's requirements.
GRIT SIZE :
Available in all grits and micro grits as per FEPA standards. It is chosen based on the quantity
of material removal and desired finish.
CONCENTRATION :
It means the quantity of Diamonds or CBN in the rim. 100% concentration means 4.4 carats
per Cubic Centimeter. A high concentration means the wheel lasts longer, denser and less
malleable. It is very necessary to select the right grit size and concentration to achieve the
best results while grinding.
BONDS :
The most important part of the wheel. The right bond holds the grit unit it is optimally worn out.
Insufficient bond holding causes a quick wearing out of the wheel where as an excessive
holding generates high temperature and clogs the wheel effecting its cutting action. Our
bonds are prepared with synthetic materials of various characteristics to give the best
advantage.

27. ADVANTAGES :
Faster Production rate - depth of the cut can be as high as 5 times the conventional in certain cases.
Longer Life - by a factor of 4 times over conventional Abrasives.
More accurate grinding - due to lower wear rates.
Wet or Dry grinding - with specially developed bonds.
Less heat generation - so less damage to cutting tool edges and greater dimensional accuracy.
Less noise and less dust generation.
HOW TO ORDER :
It is very important to provide the exact and all the necessary details while ordering to get the right
material at the right time when needed. The following shows the details to be informed while ordering a
diamond or a CBN wheel.
