Material for abrasive belt:


The abrasive unit contains 2importanntsorts of abrasives.

SiC: it can be terribly not smooth and intensely arduous, however this is used as associate abrasives is restricted to many places by its crispness. Carbides ought to be employed of chipping of lower durable materials like gray robust, chilled iron, bronze, aluminium, copper, brass and non-metallic materials. A special kind of carbide, inexperienced in color, is employed to grind carbide-pointed tools.

AlO3: this can be comparatively not sharper than carbides however are way harder. It ought to be employed in the chipping of material having higher tensile strength like Steels, toughenedmalleable iron and robust alloys. There is conjointly another kind of corundum that is white in color as against the traditional brown selection. This white aluminiumoxidetends to fracture a lot of without delay than the regular (brown) corundum, and a lot ofand slicker cutting edges area unit thus conferred to the work. Grinding wheels of white aluminium oxide ought to be designated once grinding hardened tool steels or to be used normally tooling area
Grit size.


The stand (or) base is to hold the entire machine. The 2 conveyor roller is fastened to the 2 finishs of the frame stand with the assistance of end bearing (6202) with bearing cap. The conveyor roller shaft is coupled to the one section induction motor with the assistance of v-pulley and belt drive mechanism. This total arrangement is employed to rotate the abrasive belt from one place to a different place with the assistance of conveyor mechanism.

Bearings square measure coated by bearing cap that is welded to the frame stand. The motor block and roller block is connected by the v-belt drive mechanism. The abrasive belt is mounted on these 2 roller wheel so it'llrunning endlessly.

Working of unit

This machine is fastened on the work table, wherever the compound rest. Wherever the motor is on, the abrasive belt and therefore the roller wheel are revolved, on the rate of concerning. Job is persisted the hand, for instance, if we tend to grind a surface of a body, the abrasive belt are rotating on higher rate.

Depth of grinding is also given by cross slide, and therefore thelongitudinalmovement are given by manual feed. Usually depth per cut are zero.02 to 0.05 mm. The grinding stone is connected to the roller shaft so the emery wheel is revolved. The delicate grinding operation is completed with the assistance of emery wheel.


design and drawings

design calculation: rate of the abrasive belt ought to be high.for this victimisation commonplacemotor having 1440 rate, the abrasive belt speed is reborn to higher rate.

Formula:d x rpm = d1 x rpm1
d - the motor block diameter
d1 - main shaft block diameter
as per our style
d - 76 millimetre
d1 - 47 millimetre
motor rpm - 1440
main shaft rate = (d x motor rpm )/d1
= (76 x 1440)/47= 2300 rpm
