Cumis crankshaft grinding wheels are made using special, high performance bond systems in an unique manufacturing process, tailored to suit each market segment. This manufacturing technology coupled with the application engineering expertise offers, makes Cumis crankshaft grinding wheels highly cost-effective. Besides optimizing grinding efficiencies, these wheels also provide a surface finish as 4 microns. Cumi also makes dual grade, sandwich wheels with harder sides and softer centres, ideal for grinding crankshafts of differential hardness in diameter and fillet radius. These provide surface speeds up to 60 mps.

Cumis versatile range of cylindrical grinding wheels are used for a variety of grinding operations that require size generation, fine surface finish and fast stock removal. Special wheels are also available for multiple diameters and shoulder grinding with pre-formed wheel faces, where wheel grindings are adjusted for plunge grinding. Cumis cylindrical grinding wheels find wide application in the grinding of valves, plunger pins, eye bolts, transmission shafts, bearing races, Camshafts, crank shafts etc.

Cumi wheels cater to bench grinding, low speed snagging and various other general purpose applications. These wheels are made of specially processed brown aluminum oxide (A) and green silicon carbide (GC) abrasives that give rapid grinding action, cooler cutting and excellent finish. The self dressing property of these abrasive result in higher productivity of the wheels. Suitably designed bond systems are used to hold the abrasive strongly, thereby resulting in higher material removal rate and longer life. Cumi produces the largest volume of these products in India and reaches them to customers through an excellent distribution network.

Cumis Razor Blade wheels are made of a special resilient bond with fine grit silicon carbide manufactured under a strictly monitored hot press moulding process. These include: Rough Hone Wheels First Hone Wheels Final Hone Wheels The Razor Blade Wheels are extensively used for grinding carbon steel blades, stainless steel blades, stainless steel blades, double edge and twin track blades. Cumi one of the few manufacturers world-wide has the advanced technology for making semi finishing and finishing wheels.

Cumi was the first abrasive manufacturer to import-substitute Rubber Bonded Control Wheels and Centerless wheels in India, where it enjoy 90% market share. Special features of these wheels are Longer wheel-life Lesser dressing frequency Superior from retention Superior surface finish Cumi offers rubber bonded control and centreless grinding wheels for Bearing Industry Automobile Industry Hydraulic Industry Cutting Tool Industry

Cumis Roll Grinding Wheels are extensively used in steel rolling mills for grinding the rolls in their roll in their roll shop. Cumi has the complete product range to grind various types of rolls for Hot as well as Cold rolling mills. Cumi has both conventional and microcrystalline abrasives. It offers exceptional cutting action with less wheel wear.

Cumi is one of the very few manufacturers today producing the complete range of wheels for the cutting tool industry. Cumis unique bond system cater to variety of applications in the cutting tool industry. These bond systems provide better form retention and also reduces cycle time through higher material removal rate. The latest generation SG products gives much higher in feeds, lower cycle time and generates high tolerances at lower cost per tool.

Cumi also manufactures Crank Wheels for Engine re-building industry. These wheels are used for re-grinding crankshafts with the traverse grinding method.

Internal grinding is a process of finishing the inside diameter of the component to and accurate size and desired finish. The high contact areas in this application poses a challenge and Cumi offers Both conventional & high performance wheels.

These wheels are made with Silicon Carbide Grains and Available in Green (GC) and combination (CGC) grains. Silicon carbide are harder than Aluminum oxide which makes them ideal for grinding low tensile materials like tungsten carbide, grey iron, unannealed malleable iron and Non-Ferrous materials, A special bond system goes into the making which imparts superior properties like: Excellent form retention Dimensional accuracy Surface finish

Used for polishing Valve seats and disks

Cumi wheels cater to Saw grinding application, These wheels are made of specially processed brown aluminum oxide (A) that give rapid action, cooler cutting and excellent finish. The self dressing property of these abrasive result, 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.

The Snagging wheels designed for Pedestal Grinding comes in the full range for Grinding various work material, These wheels are designed for giving long wheel life while maintaining good cutting action.

Product Features High safety and consistency New Generation Bond system Excellent free cutting action Heavy Stock remova Better form retention Excellent component finish Lesser dressing frequency
