    Sheffield Model 110 Multiform Grinder

    The model 110 grinder is a versatile, high speed production machine designed for grinding cylindrical parts of intricate and precise profile. Feed and control functions are performed automatically permitting the operator to manage more than one machine at a time. The principle uses of this grinder are:
  • .250 Rt, .250 elevated temperature and .350 diameter tensiles.
  • Combinations and smooth stress ruptures.
  • NACE stress corrosion.
  • Gleebles and slow strain rate test specimens.
  • Fatigue tests with gauge length up to 1.00".


    • Two Sheffield Model 187 Multiform Grinders

    In addition to the above mentioned benefits, the model 187 is used to grind:
  • .500 diameter room temperature and elevated temperature tensiles.
  • Fatigue tests with gauge length up to 2.00".


    • Jones and Lamson Model 410 Thread and Form Grinder

    This equipment is used to:
  • Notch cylindrical specimens to final dimension.
  • Thread grinding.


    • Three Charpy "V" Broach Machines
  • Notch Charpy and Izod specimens.


    • Two Thompson Surface Grinders

    For precision grinding of impact and fracture mechanics samples.


    Two Engine Lathes

    Lathes are used for general turning operations with specific uses presented below:
  • Turning straight and step down magnetic particle test.
  • Jominy hardenability.
  • Fixtures for test machines.


    • Two Vertical Mills
  • Vertical mill is used primarily for locating and drilling clevis pin holes at precise locations in
        compact tension and DCB samples.
  • General light milling operations.


    • Horizontal Mill

    Horizontal mill operations are:
  • Milling crack starter notch in compact tension and DCB specimens.
  • Reduced section tensiles.
  • V and U notch in high temperatures alloys and austentic stainless steel charpys.
