JASH Vibration Isolation Work Table (VIWT)is mainly known as Optical & Opto-Electronics Laboratory Work Table used in Laboratories as Work Station forPASSIVE ISOLATIONfor sensitive equipment like Laser, Optics, Optical and Electronic Scales, Medical Equipment and measuring instruments. These precision work tables are also used in Metrology Rooms / Laboratories for measurements of very precise components like roundness testers, gear measuring machines, surface measuring machines, etc. The top working surface of Vibration Isolation Work Table (VIWT) can have very precise top working surface conforming to Grade II or Grade I or Grade 0 flatness accuracy as per DIN 876 or IS: 2285 / IS: 7327 or other Customer specified surface flatness accuracy finer or coarser as may be required. The work table can be of Granite Stone or SH-V Stress Relieved Gray Cast Iron. The Work Table top surface can have features of drilled holes, tapped holes, guiding grooves, milled T-slots or any other features as may be required for applications.

VIWT has feature of low frequency isolation and self leveling of Work Table. Work Table can be isolated from vibrations up to (a) Vertical natural frequency approximately 2.0 Hertz or better and (b) Horizontal natural frequency approximately 3.0 Hertz or better. For some applications coarser vibration isolation up to about 102 Hertz or more can also be supplied. Get high quality vibration isolation table from the leading manufacturer and supplier of precision tools.The basic structure of typical Vibration Isolation Work Table (VIWT) starting from bottom is as follows:

1. SH-V stress relieved torsion free welded steel tube frame that is supported onto adjustable feet underneath frame legs essentially resting onto firm, rigid, non-flexural and stable floor. Optionally, in addition to adjustable feet the VIWT frame can also have as an option castor wheels mounted onto VIWT frame to facilitate move / relocate work table system as required. Unless specified otherwise the standard adjustable working height of work table surface is 90025 mm from floor level. Standard supply is frame without castor wheels.

2. Vibration Isolation Air Springs are strategically located and fixed on to top of the VIWT frame. Work table is supported on to minimum four air springs at Airy / Bessel Points of supports (1/4 to 1/5 from sides) and is leveled on 3-point leveling system. Depending upon overall work table size air springs could be more than four. Unless specified otherwise standard passive vibration isolation will be about 102 Hertz.

The frame also has mounted air filter regulator unit with respective air tubing for air springs and level control system. A 3-point level control valve unit is mounted on to the VIWT frame. The system requires on-line clean, moisture free & oil less dry air at 5 bar pressure. No oil lubrication is required for the system.

If not specified, standard active / auto level control will have approximate leveling accuracy up to 150 microns.Optionally, the system can have very accurate active / auto level control system that can approximately auto level the work table to an accuracy up to 20 microns.

3.As required the work table that can be of either Granite Stone or SH-V Stress relieved Gary Cast Iron or non-magnetic stainless steel. The top working surface can have array / grid of tapped holes or any other features like drilled holes, guiding groves, T-slots as well as User specific.

JASH C.I. Layout and Marking Tables serve as a reference base for inspection, tool making, gauging, spotting marking and layout operations, supported on suitable stands. Stands enable proper leveling of plate and help provide the top surface at a convenient working height of approx. 750 to 800 mm from the floor.

JASH have manufactured and supplied large number of big size Surface Plates / Tables in India as well as for Exports. More than 1000 numbers Cast Iron Surface Plates of 3000 x 2000 mm unit size and 500 numbers 4000 x 2000 mm unit size made from single casting are being used by various industries in India and abroad.
