A Basic Guide to Abrasive Mounted Points

What are Abrasive Mounted Points?

Abrasive mounted points are very small bonded abrasives or superabrasive wheels with a ball, point, cone, cylinder, or bullet shape. They are mounted on a pin or mandrel for portable die grinder and deburring applications. Abrasive mounted points are the general name for a kind of small grinding tool with shank. Product specifications for abrasive mounted points include abrasive grain type, abrasive grain size, grit or grating system, performance parameters, applications, and bond type. Abrasive grain size is usually specified according to ANSI, FEPA, or JIS standard. So far, vitrified mounted points, resin-bonded mounted points, rubber mounted points, diamond mounted points, center lap mounted points, and abrasive cloth mounted points have been listed as major classifications of abrasive mounted points. The shapes of abrasive mounted points vary. Ball, cone, cone-ball nosed, countersink 60°, cylinder, cylinder-ball nosed, inverted cone, and other.

Different Bonding Agents

Abrasive grains for vitrified mounted points are usually brown fused alumina, white fused alumina, pink fused alumina, silicon carbide, zirconia alumina, synthetic diamond, cubic born nitride (CBN), tungsten carbide, and abrasive grains with a metal layer or coating are made by vitrified bond, supported by a metal shank in the center. Major application fields of vitrified mounted points include grinding of all kinds of metal, bore inner diameter, and mould amendment. Rubber mounted points are made by finer grit abrasive grains and used for mould polishing. Abrasive cloth mounted points are composed of pieces of rectangle abrasive cloth that are bonded around the metal shank. The grit size is from 60# to 320#. Abrasive cloth mounted points are used for polishing bore inner diameter. Diamond mounted points are a kind of grinding tool for nonmetallic materials, such as stone and porcelain materials. Diamond mounted points have a high grinding performance and are east to be manufactured at a low cost. As a result, diamond mounted points are suitable for large-scale grinding and processing. Center Lapping is used when you need to finish center holes in parts that require turning or grinding between centers. Center Lap Mounted Points are wax treated to minimize loading.

Performance Specifications

There are three main performance specifications for mounted points: rotary speed, shank diameter or bore inner diameter (ID), and outer diameter (OD). Rotary speed is the maximum speed or range recommended by the mounted points supplier. The bore is the ID of the center mount of the abrasive product, and is used to mount or hold the abrasive on a spindle or mandrel. The shank diameter is the diameter of the integral shank, pin, shaft or mandrel on mounted points or wheels. When selecting mounted points, OD should also be considered.

Different Applications

Mounted points are used in many different applications. Some products are used in dry grinding, wet grinding, material removal or roughing, blending or intermediate cutting, or finishing and deburring. Others are used in polishing and honing, cylindrical or centerless grinding, form or gear grinding, bench or backstand grinding, or portable grinding. Mounted points for cleaning or surface preparation, creep-feed grinding, and tool room or sharpening applications are also available.Almost all types of abrasive mounted points that are used in a great variety of applications can be found on iAbrasive.com, an international abrasives trading marketplace.
