3 Tel: / Fax: Huyler St / So. Hackensack, NJ 076 USA TOOLROOM GRINDING APPLICATIONS Toolrooms are found in almost every manufacturing plant throughout the country. They may be called by other names such as: machine shops, maintenance shops or repair shops, however the work done is virtually the same. Toolroom grinding involves the production, maintenance and repair of cutting tools and machinery parts used in all types of manufacturing operations. TYPE STRAIGHT TYPE CYLINDER Surface Grinding The grinding of flat, contoured or angular surfaces on a workpiece which is passed in a horizontal plane against a revolving grinding wheel. Surface grinding applications range from heavy, rapid stock removal operations to precision contouring. TYPE RECESSED ONE SIDE TYPE 7 RECESSED TWO SIDES TYPE 6 STRAIGHT CUP TYPE FLARING CUP Tool and Cutter Grinding The grinding or resharpening of milling cutters, reamers, drills or end mills for the purpose of restoring keen cutting edges or exact cutting angles. TYPE DISH TYPE 3 SAUCER Medalist Ceramic Alumina Gold 3AR AA GC Medalist blue wheels are ideal for grinding all high speed tool steels, especially the most difficult to grind. For the highest productivity, longest life and coolest grind on moderate to very heavy stock removal applications. 3AR abrasive is the industry s best, most versatile aluminum oxide abrasive for toolroom grinding and is ideal for grinding all types of tool steels. Great for medium to heavy stock removal. Gold 3AR wheels are gray/purple in color. AA is our most friable aluminum oxide abrasive. It is outstanding for cool, fast cutting action on high speed steels and cast alloy steels. Best for light to medium stock removal. AA wheels are white in color. GC is the abrasive of choice for grinding carbide tooling, as well as other nonferrous materials because silicon carbide is very sharp and very hard. GC wheels are green in color. How To Use Toolroom Basics Abrasive: Select abrasive type based on performance, stock removal rate and material style. : Select the grit size depending on finish required, stock removal rate needed and corner/form holding requirements. Bond: Select the appropriate bond based on the abrasive selected, and the contact area.* Grade: Selection based on bond selected, contact area* and heat sensitivity/thickness of material to be ground.
