4. About HMT Ajmer
HMT Ajmer plant was orignally established as “
Machine corporation of India limited” in january

7. Manufacturing Department
Heavy Parts :
It is the shop which gives the shape to the
largest castings which comes from the foundry shop after
being painted rough.
This Section is divided into two sub-sections
1. Planning
2. Boring
8. 1. Planning
In this section, the job planning is one of the basic
operations done for machining process.
The figure shows
Planning operation on
a CNC bed by
Plano-Milling Machine.
9. 2. Boring
Boring is the operation of enlarging an already drilled hole.
The holes are predrilled as in casting only.
10. Small Parts
The section is primarily concerned with the manufacturer of small parts
of machine tools. The section is further divided into six subsections.
Spindle Section Round Section Turret Section
Non Round SectionGear Section Sheet Metal Section
11. Foundry Shop
It is a shop where metal is melted for casting purpose. In foundry Shop
castings of different parts of grinding machine like bed, body, work head
& wheel head are prepared by using moulding box, pattern & moulding
Induction Furnace Melting Process of Cast Iron
12. HMT has 3 furnaces, two of 3MT capacity and one of 1.5MT
capacity.
All furnaces are induction
type & temperature in the
furnaces reaches up to
1400-1450˚C.
13. Casting
In this process, a liquid material is usually poured into a mould, which
contains a hollow cavity of the desired shape, and then allowed to
solidify.
