9. Foundry Shop
Foundry is a shop where metal is
melted for casting purpose. The
melted metal is poured into the
mold and left for sometime for
solidification.
HMT has 2 furnaces, One of 5T
And other of 3T capacity .
All furnaces are induction type & temperature in the furnaces
reaches up to 1400-1450˚C.

10. 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.

11. 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
Gear Section Non Round Section Sheet Metal Section
Turret SectionRound Section

12. 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
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.

13. Boring: Boring is the operation
of enlarging an already drilled
hole. The holes are predrilled as
in casting only.

15. CNC Assembly
Computerized Numerical Control
Conventionally, an operator decides and adjusts various machines
parameters like feed , depth of cut etc depending on type of job , and
controls the slide movements by hand. In a CNC Machine functions and
slide movements are controlled by motors using computer programs.
Various CNC machines produced in HMT Ajmer unit are: GDS-15/22, GC-
175/225 ,GCL-140/200,IG-100/150 etc.
