Central Mechanical Workshop (CMW) is  centralised infrastructural facility for the development, fabrication and assembly of mechanical portion of R & D projects undertaken by the organization. The workshop often suggests necessary modification in the design as per the available infrastructure and manpower. It is a matter of great pride that shop floor is equipped with sophisticated machinery for carrying out  complex operations and machining of intricate components.

Shop floor covers an area of 2500 sq mt. with a sanctioned load of 250Kw. It has healthy working environment and congenial atmosphere. There are 51 trained staff personnel well versed in their respective trades such as Turning, Milling, Fitting, Precision machining etc and are equally divided in five different sections

Section I

 Milling section

                     Section II 

 Turning section 

SectionIII                            

 Fitting & sheet metal

Section IV      

 Planning section

Section V        

 General section

 

It has an excellent metrology lab well equipped with measuring standards and instruments. Precision measuring machines/systems are of immense value and add credibility to the organization. Besides linear dimensional measurement of precision fabricated components, undertakes the inspection and calibration of measuring standards/instruments from both Govt. and private Institutions.

CMW is ISO 9002 certified and works on laid principles / procedures for maintaining Quality Policies and Objectives of the organization. The improvements in quality system through audits/surveillance help in achieving the organizational goal and establishing its credibility worldwide.

 

Facilities  available

The shop floor has many specialised area of activities so as to manage the development and fabrication of any intricate profiled components. They are

Besides the host of basic machinery like lathes, milling, grinding and other general machinery, with which an ideal bench marked shop floor must be equipped, CMW has the following list of sophisticate and precision machinery

Jig  Boring

 

Jig  Boring  Machine “ ACIERA” is designed  to bore  accurate  holes  with precise location and have  consistency, repeatability  in  measuring  system. The digital read out  enable to display  accurately  its  coordinates  axis (X,Y&Z). The data of the coordinates  are stored for any  batch  production  required. The machine is of great utility in fabrication jigs & fixtures  for large production of  components  offline. Both rotatory/angular  and Cartesian  coordinate  system are use for accurate  positioning  and  holing .  The machine is also used for milling  reference  surfaces as per the need.

Hobbing  Machine

The  Hobbing Machine  “MIKRON”  (Swiss  Make)  is  suitable  for the hobbing of  wheels  and  pinions with straight  teeth. The hobbing of involute  teeth  using the self-generating hobs  cutters  with straight profile are its salient features. The teeth so produced are  of  epicycloidal  profile and matches   with that of the driven  gear such as rack, pinion etc. The hobs have certain  limitation  towards the number of teeth  to  be cut and  are mark in reference to the module  or DP cutters. Special teeth, such as those for indexing gear  of ratchet  wheels, circular saws  and  chain  wheels can  also be produced.

Thread Grinding
Thread Grinding  Machine  “Matrix” (Swiss  Make) is designed for the usage  of minimum number of links  in transmission  mechanics  so as to have  more  reliability, less  accumulative  errors  and  precision  while machining. It is to carry  out the right  selection of pitches  and its  measurements  as per the available  standards. It provides  highly  accurate  GO-NOGO  gauges, gears, hobs, external  threads, parallel or tapered, and   plain  or relieved  of  various  standard  pitches  etc.  
     

Facilities updated/procured recently


 

Recently procured CNC (computerized numerically control) vertical milling machine, Bridgeport Interact 4, series II has unique salient features i.e visualising the component on the monitor, before it is actually being machined and also its step-by-step programming. Besides the milling basic operations, free contouring in 3D adds complexity to the machine.  Machined program if required, can be stored for any repeatability or batch production. In addition it is connected to PC  through RS-232, serial interface for off line programming.
