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.

In line with the policy of constant innovation, cumi's new peak range of precision wheels are designed to meet very high performance parameters. Grinding wheels which are truly peak in name and performance. The peak range of bonded abrasives includes centreless wheels and toolroom wheels available as standard stocks in a varied range of grits and sizes. Peak centreless wheels are made of brown aluminium oxide grains (a) and are available in 2 versions (depending on the bond used) in different sizes and grit combinations. The unique characteristics of the two special bonds v1092 and v2016 used, make these wheels distinctly superior in quality and performance. V 1092 : highly fusible and cool-cutting bond which ensures better form retention and surface finish. This high life-bond is ideal for difficult-to-grind materials. V 2016 : a special bond, with a unique characteristic of controlled fracturing. , which enhances the holding capability of the abrasive grain and also increases its life. It also ensures lesser dressing frequencies and reduces the dressing depth by half. This high-life bond also gives better form retention and a superior component finish.

Depending on the application, cutting tools are manufactured using different grades of hss. Non-cobalt and cobalt grades are widely in use and material made by powder route is also gaining increased adaption. The work material, its hardness, the machine tool used, part configuration, finish required on the components and volume of components to be produced are a few requirements that influence selection of different grades of hss for manufacture of cutting tools

Manufactured with straight flute design and 45° lead cutting angle, are suitable for ferrous metals and for many non-ferrous & non-metallic materials. Also available in left hand spiral which help cutting action load the spindle & eliminates reamer feeding too freely. Left hand spiral prevents chips from working back into the flutes & possibly scoring the hole wall. They are ideal for cast iron, brass and many plastics, when negative shear is more effective. Special tolerance available against specific enquiries/ orders. Size range: 1/64' to 5/8' / 0. 35 mm to 16 mm (0. 35 to 6. 4 mm in increment of 0. 05 mm, 6. 5 to 12mm in increment of 0. 5 mm, 12 to 16mm in increment of 1 mm).

Solid carbide end mills are a wise choice for many milling applications. They are ideal on tough or abrasive materials. Carbide also has the benifit of high heat resistance. On many jobs, solid carbide end mills can be run faster than hss or cobalt end mills, resulting in much higher productivity rates thereby lowering tool setting time / down time. Additional benefits of rigidity of carbide is its high precision and excellent surface finish. Carbide end mills are successfully being used for severe metal cutting operations (high nickel based alloys) which require high strength. In general the more flutes on end mills, the better the machined finish. If workpiece finish is of major importance select four or more flutes. For higher production rates fewer flutes will allow higher chip carrying capacity.
