Tractor Hydraulic
It is a system which used to lift the weight using the pressurized hydraulic oil.
The important component of the system are following:-
Hosing Distributer Main shaft Torsion shaft Draft tube Lever with cam Cylinder piston and connecting rod
PATTERN: - PATTERN IS SIMPLY THE REPLICA OF THE DESIRED CASTING.

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.
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.
Plano milling machine
This is similar to a double housing planer but the tool can be milling tool. One of the machines is TNC (three axis turning centre) in which only one axis can be moved at a time. Thus round jobs cannot b machined here.
Another machine is CNC in which two axis can be moved simultaneously to machine round job. The length of the bed is 2800mm.
Maintenance shop
Type of Maintenance: Break-down Preventive ReconditioningImportance of Maintenance: To maintain the accuracy of machine. For the safety of operator. To maintain the efficiency of machine.

CNC TRAIN MASTER MACHINING CENTRE VMC 200T PC:- An economical and user-friendly PC based system specially designed to train
operators, technicians and engineers in CNC machine tools operation and programming.
Compact table top mounted model most ideal for training institutes & technical institutes.
3-Axis continuous path CNC system. Manual tool changing with CNC prompting. Stepless DC drive with RPM and load indication for headstock. Hardened and ground spindle runs in precision antifriction bearings. PC Based economical CNC system best suited to educational institutions. Recirculating ballscrew and nut arrangement for longitudinal axis.
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.
