Measurement is the essence of precision tool fabrication as each minute value can bring about a major change. JASH offers measuring machines with 3D coordinate compilation and layout marking capabilities. Leave no scope for errors in measured values with our state of the art measuring machines.
JASH Vibration Isolation Work Table (VIWT) is mainly known as Optical & Opto-Electronics Laboratory Work Table used in Laboratories as Work Station for PASSIVE ISOLATION for sensitive equipment like Laser, Optics, Optical and Electronic Scales, Medical Equipment and measuring instruments.
JASH Granite Surface Plates are used for precision gauging, inspection, layout and marking purposes. They are preferred by Precision Tool Rooms, Engineering Industries and Research Laboratories because of their following outstanding advantages.
No rust, no corrosion, relatively warp-free, no compensating hump when nicked, longer wear, smoother action, greater precision, non-magnetic, less care after commissioning, lower co-efficient of thermal expansion and non-glaring surface. These features make JASH one of the best granite surface plate manufacturers in the industry.
