Fully integrated operations include mining, fusioning, power generation (wind & hydro), manufacturing, marketing and distribution. Manufacturing facilities at Tiruvottiyur (Chennai) and Hosur with ISO 9000 accreditation for quality standards.




Crankshaft Grinding Wheels
CUMI with more than 75% market share in India offers crankshaft wheels for grinding an entire range of crank shafts used in Light and Heavy Commercial vehicles, motor cars, two wheelers, generators and even in marine engines.
 
Cylindrical Grinding Wheels
CUMI's versatile range of cylindrical grinding wheels are used for a variety of grinding operations that require size generation, fine surface finish & fast stock removal. Special wheels are also available for multiple diameters & shoulder grinding with pre-formed wheel faces, where wheel grindings are adjusted for plunge grinding. CUMI's cylindrical grinding wheels find wide application in the grinding of valves, plunger pins, eye bolts, transmission shafts, bearing races, cam shafts, crankshafts etc.
 
General Purpose Grinding Wheels
CUMI offers speciality wheels to cater to bench grinding, low speed snagging and various other general purpose applications. These wheels are made of specially processed brown aluminium oxide (A) and green silicon carbide (GC) abrasives that give rapid grinding action, cooler cutting and excellent finish. The self-dressing property of these abrasives results in higher productivity of the wheels. Suitably designed bond systems are used to hold the abrasives strongly, thereby resulting in higher material removal rate and longer life. CUMI produces and markets the largest volume of these products in India and reaches them to customers in diverse user industries through an excellent distribution network.
 
Rubber Control and Centreless Wheels
CUMI was the first abrasive manufacturer to import substitute Rubber Bonded control wheels and Centrelss wheels in India, where it enjoys 90% market share.
 
Tool Room Grinding Wheels
Tool room grinding wheels find vast applications in the manufacture and regrinding of cutting tools like drills, reamers, milling cutters etc., These wheels are of white aluminium oxide (AA), green silicon carbide (GC), pink aluminium oxide (RAA) and brown aluminium oxide (A) abrasives. Owing to their friable nature and sharp edge retention properties, CUMI's Tool Room wheels give very high productivity. An exclusive bond system goes into their making which imparts superior properties like:
  • Excellent form retention
  • Dimensional accuracy
  • Surface finish
 
Vitrified Centreless Grinding Wheels
CUMI's range of Centreless grinding wheels include the versatile and time tested bond systems V10, V45 and V60. Available in different sizes and grit combinations, these wheels find wide application in all centreless grinding operations. Ideal for difficult-to-grind materials, these wheels give safety tolerance of upto 60 mps. The unique characteristics of the highly fusible and cool cutting bonds used also impart:
  • Better form retention
  • Excellent component finish
  • Lesser dressing frequency
 
HSS Cutting Tool Manufacture
The cutting tool is one of the most important elements necessary for realizing the full potential of any metal cutting operation. Carefully chosen grinding wheels are essential to enable the cutting tools obtain sharp edges and accurate geometry.

The prominent cutting tool materials that are being used today are High Speed Steels (HSS), Carbides, Ceramics, Cubic Boron Nitride (CBN) among these materials, HSS still dominates the field because of their versatility and low cost. Table I gives the approximate composition of commonly used Molybdenum - based HSS.
