Commonly Used Pattern Materials
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 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.
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.
Mould
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
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.
Boring: Boring is the operation of enlarging an already drilled hole. The holes are predrilled as in casting only.
GPM Assembly
General Purpose Machine.
These are generally manually worked machines involving no computerized or numerical control. These are semiautomatic in nature. Following machines are manufactured in GPM assembly section.
In HMT, Pinjore unit primarily four types of GPM are manufactured-1. FN2 Milling Machine2. FN3 Milling Machine3. Turret Ram Milling Machine4. Broaching Machine
Machines are further classified into Horizontal, Vertical and Universal Milling Machines.
FN2 Milling Machine FN3 Milling Machine
Broaching Machine Turret Ram Milling Machine
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 Pinjore unit are:HMC 320M, HMC 400M, HMC 500M, HMC 600M, HMC 800M, VMC 400M, VMC 500M, VMC 800M, VMC 1000M etc
