Surface Grinding Report

Surface grinding is a machining process that uses an abrasive wheel to remove material from the surface of a workpiece to create a flat surface. The grinding wheel cuts chips as it spins, making the surface smooth. A surface grinder holds the workpiece in place with a magnetic or mechanical chuck and moves it past the grinding wheel. There are several types of surface grinders including horizontal spindle, vertical spindle, and double disc grinders. Surface grinding provides benefits like grinding hard materials, high accuracy, easy workholding, and a smooth finish. Calculations are provided for feed rate, depth of cut, velocity of the workpiece, and grinding time.

SURFACE GRINDING REPORT

DJJ 5032: MECHANICAL WORKSHOP PRACTICE 4

THEORY
Surface grinding is used to produce a smooth and flat surfaces product. This process is widely
used which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or non-
metallic substance from a work piece, making a face of it flat or smooth.

Surface grinder is composed of an abrasive wheel, a work holding device known as a chuck,
and a reciprocating or rotary table. The chuck holds the material in place while it is being worked on.
It can do these one of two ways: ferromagnetic pieces are held in place by a magnetic chuck, while non-
ferromagnetic and non-metallic pieces are held in place by vacuum or mechanical means. A machine
vies (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold
non-ferromagnetic work pieces if only a magnetic chuck is available.

Types of surface grinders:

1. Horizontal-spindle (peripheral) surface grinders.

2. Vertical-spindle (wheel-face) grinders

3. Disc grinders and double-disc grinders.


Benefit of Surface Grinding:
 Can grind very hard or abrasive materials.
 High degree of dimensional accuracy.
 Work holding is easier because of magnetic chuck.
 Produces surface textures of very high finish.

CALCULATION

Feed of Rate (FOR):


FOR = 0.02 × 10
= 0.2 mm @ 200 μm

Depth of Cut (DOC):


DOC = 0.002 × 15
= 0.03 mm @ 30 μm

Velocity (VOT):
Distance = 15.14 × 2
= 30.30 cm @ 0.303 m

Time = 1.92 seconds

0.303
VOT =
1.92

= 0.16 m/s
