PPT on HMT Ajmer (Mechanical Dept.)

  1. 1. Summer Traning Presentation on HMT Machine Tools Ltd. SUBMITTED TO: Department of Mechanical Engg. Bhagwant University, Ajmer (Raj.) SUBMITTED BY: Ashu Ranjan B.Tech (Mechanical Engg.)
  2. 2. About HMT  Established in 1953. HMT Machine Tools Ltd was formed as a wholly owned subsidiary of HMT Limited in August 1999. Over the years diversified into Watches, Tractors, Printing Machinery, Metal Forming Presses, Die Casting & Plastic Processing Machinery, CNC Systems & Bearings. Manufactured and supplied over 100,000 machines till date for domestic market. Exported over 18,000 machines.
  3. 3. HMT,AJMER  HMT AJMER PLANT WAS ORIGNALLY ESTABLISHED AS “MACHINE CORPORATION OF INDIA LIMITED” IN JANUARY1967.  THIS UNIT WAS SUBSEQUENTLY MERGED WITH HMT LIMITED ON 1 APRIL,1975.
  4. 4. HMT UNITS IN INDIA  Topics to be Covered  Part Design  Tooling Design  Machine
  5. 5. Departments •MACHINE TOOL DEPARTMENT •TRACTOR DEPARTMENT •FOUNDRY DEPARTMENT •MAINTENANCE DEPARTMENT •ASSEMBLE DEPARTMENT
  6. 6. Machine Tools Machine Tools Departments Heavy Parts & Tool Room Small Parts Pattern & Material Testing Cnc Assembly
  7. 7. 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
  8. 8. Pattern Shop PATTERN:- PATTERN IS SIMPLY THE REPLICA OF THE DESIRED CASTING.
  9. 9. Commonly Used Pattern Materials 1 . WOOD 2 . METAL (ALUMINIUM, CAST IRON, BRONZE) 3 . THERMOCOL 4 . RUBBER
  10. 10. Types of Patterns Used  Match Plate Pattern  Cope and Drag Pattern  Loose Piece Pattern  Gated Pattern  Skeleton Pattern  Shell Pattern
  11. 11. Types of Patterns Used  Loose Piece Pattern  Gated Pattern
  12. 12. 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.
  13. 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.
  14. 14. 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 Gear Section Non Round Section Sheet Metal Section
  15. 15. 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 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. 2. Boring
  16. 16. Boring: Boring is the operation of enlarging an already drilled hole. The holes are predrilled as in casting only.
  17. 17. 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.
  18. 18. Maintenance shop  Type of Maintenance: Break-down Preventive Reconditioning  Importance of Maintenance: To maintain the accuracy of machine. For the safety of operator. To maintain the efficiency of machine.
  19. 19. CNC TRAIN MASTER MACHINING CENTRE An economical and VMC 200T PC user-friendly PC based system to meet training requirements in CNC machine tools operation & programming Table size mm 420x125 Max. job weight kg 20 Axes travel – Longitudinal mm 200 Axes travel – Cross mm 125 Axes travel – Vertical mm 200 Spindle motor kW 0.44 DC Feed rate mm/min 2-550 Rapid traverse rate mm/min 700 Feed rate mm/min 2-550 Spindle taper Spindle speed range (stepless) ISO 30 rpm 200-2000
  20. 20. 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.
  21. 21. 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, GC175/225 ,GCL-140/200,IG-100/150 etc.
