Central Workshop

Central Workshop of the CSIR-National Physical Laboratory provides technical services related to design, drawing and development of new experimental set up/instruments, fabrication of high precision components, repair and maintenance of existing instruments/setup required by the various section of the laboratory. In addition to that this facility also provides inside campus mechanical maintenance and other related work etc. The central workshop equipped with the state-of-the-art facilities:- 
  • 4-Axis Deckle Make CNC Milling Machine with FANUC Controller
  • Precision Lathe Machines
  • Micro Milling Machines
  • Tool and Cutter Grinder
  • Precision Surface Grinder
  • Sheet Metal and Fitting Shop
  • Welding and Glass Technology Workshop
During Covid-19 pandemic condition, the Central Workshop supported the Testing Facility Project for PPE Kits, Ventilators and IR Thermal Body Scanner by fabricating a number of components/ parts in shortest possible time. Some of the items/ parts fabricated are Hydrostatic Resistance Test set-up as per ASTM D-751, Spray Head of Impact Penetration Set–up, Particles on Mask Sampling (PMS) probe as per IS/ASTM standard, Set-up for Water Wave Transmission Rate (WVTR) Testing. Also some of the fabrications and fitting works were carried out for Mechanical Blood Pressure Measuring System for Legal Metrology Department, Govt. of India. Beside this, the central workshop helps in the maintenance of Apex level standards and establishment of new facility/Instrument, fabrication of the accessories and components used for calibration and testing in the different standards lab.
