Gear Grinding is very high precision finishing operation constitutes removal of considerable amount of excess material from gear teeth flank. Gear Grinding Process is generally executed on gear teeth after Heat Treatment process to achieve desired Quality Parameters within permissible dimensional tolerences, i.e surface finish as well as surface texture, accuracy in form & profile.
Cumi's Gear Grinding Products are manufactured through in-house state-of-art facility. As per recent advances in Gear Grinding process, CUMI has emerged with next generation high performance Bond as well as special Abrasive. Through special Krystal Bond (V500 & V736) and Micro - Crystalline Abrasives (MSB & 83R), we are very much capable to customize our products to fulfil customer expectations on cost & quality.

Gear Honing Process takes place by rolling off the work piece on cross-axis against Honing Ring. Honing Profile can lead to significant reduction of noise. Power Honing leads to stock removal with sufficient rate which makes pre-grinding process unnecessary or obsolete.
CUMI offers Gear Honing for extremely profiled Honing Ring.
CUMI's high Performance vitrified bonds achieve controlled stock removal rate upto 0.1 mm per flank.
CUMI's Expoxy resin bond along with a special treated Aluminium Oxide results into controlled as well as high stock removal rate.

These are divided into Vitrified, Resinoid & Rubber products and Thin Wheels and are manufactured by mixing grains with bonding material, moulding them to shape and then subjecting the output to firing or baking in high temperature and finishing the same to desired dimensions. The composition of the product depends on the type of grains and type of bonding materials used. Sizes will vary between 10 mm to 1200 mm with thickness ranging from 1 mm to 650 mm. Bonded abrasives are mostly in the form of wheels but also in other shapes such as segments, sticks etc. Bonded abrasives for internal purposes classified as Standard Products i.e. those products which are made to standard dimensions, grit sizes, shapes and grain / bond composition. These are sold largely through the distribution channel. Non Standard Products are those products which are made to exact requirements of customers. CUMIs product range boasts of over 20,000 varieties of abrasives. Bonded Abrasives are used in diverse applications like floor polishing, fabrication, polishing, off-hand tool grinding and precision grinding of diverse products like crank shaft, balls and razor blade across a wide spectrum of industries ranging from automobile, construction, fabrication, steel, bearing etc.

These are manufactured by depositing grains over a backing material like cloth, paper or fibre. depending on the requirement of the customer, the backing material and type of grains will vary. There are various types of grains like sintered aluminium oxide, silicon carbide, zircon, emery and flint. The grains are of varied sizes referred as grits and their sizes also vary from grit 12 to grit 2000. The backing on which these grains are coated will vary depending on the industry and application to which the coated abrasives are supplied. Initially, the grains are deposited over adhesive rich backing materials and jumbos of coated abrasives up to 1000 metres are manufactured. Then, depending on customer order/usage, these jumbos are converted into various shapes like sheets, belts, rolls, discs and flap wheels. The geometry of the product also differs from each other based on application equipment.
Coated abrasives are used in light polishing applications in automobile, auto ancillaries, white goods, hand and power tools, sanitary ware, furniture, fabrication and construction industry.
