Eliminate distortion and facilitate accurate inspection with JASH's Bed, Clamping and Welding Plates. The products in this category serve as excellent reference bases for inspection, tool making, spot marking, layout operations and gauging. Enhance the precision of your welding methods with high quality plates, clamps and welding beds.
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 C.I. Surface Plates and Tables serve as a precision reference base for inspection, tool making, gauging, spotting marking and layout operations. Granite or Cast Iron Surface Plates are supported on suitable stand called Surface Tables Stands enable proper levelling of plate and also provide the top surface at a convenient working height of approx. 850 to 900 mm from the floor. The adherence to high quality standards and precise configurations makes JASH a leading surface plate manufacturer and supplier in the industry and one of the best Cast Iron and Granite surface plate manufacturers globally.
