Norton Grinding Wheel Segments For Precision Grinding
£29.36 – £338.84 +VAT
Grinding wheel segments are generally used to grind flat stock or flat surfaces within a workpiece for anything from heavy stock removal to precision grinding. Available in a variety of shapes, sizes and grain types to meet your job requirement.
Description
What Is A Grinding Wheel?
The pores (hollow spaces between adjacent abrasive grains and the bond) serve to provide clearance for coolant penetration and metal chips removed in the grinding process.
When the wheel is rotated at grinding speed and applied to the workpiece, the abrasive grains cut the material that is being ground, removing the material in small chips.
The increase in grinding forces causes either the abrasive to fracture, exposing new cutting edges, or fractures the bond bridges holding the abrasive grains. In the latter case fresh abrasive grains are exposed to cut the workpiece.
In normal vitrified grinding applications, the wheel has to be dressed. By varying the properties of the abrasive, the type of bond, the make-up of the wheel, it is possible to produce grinding wheels with a vast range of different grinding characteristics.
Why Use A Grinding Wheel Segment?
Without segmented abrasives it might be impossible to grind large parts flat and parallel using a vertical-spindle surface grinder. Smaller parts can be ground with smaller vertical surface grinders using cylindrical grinding wheels, but the weight of a wheel larger than 2 foot in diameter would make it an unwieldy burden for an operator to lift and position on the machine every time the wheel needed changing.
With segmented abrasives the operator can mount the abrasive one piece at a time. The chuck holds the pieces in a circular arrangement. The smaller pieces are much easier to handle, and in arrangements that leave spaces between the segments, the spaces provide chip clearance. These segments are used in machines with reciprocating or rotating worktables.
