GMT METROLOGY RANGE
GMT manufactures surface plates, angle plates, box angle plates, straight edges, bench centres and other metrology products.
Granite Surface Plates are available in five grades. Also, the typical application of these five grades of plates is : GRADE 00 as per DIN : 876 : 84 is of laboratory grade, GRADE 0 is of inspection grade, GRADE 1 is of tool room grade and GRADE 2 & 3 are intended for use in shops for general inspection.
GMT 6-Face Master Squares finds application on any work that requires the checking of squareness or parallelism. Master squares has 6 finished faces . Finishing of square face ensures flatness and perpendicularity on the four sides, which are parallel and perpendicular to one another.
Granite Straight Edge :
GMT Granite Straight Edges find application in inspection of flatness and parallelism between two machine parts or components. GMT Straight Edges are free from curves. Lapping on both top and bottom faces to ensure flatness. Consequently, straightness and parallelism are as per International Standards and are available in various dimensions.
GMT Granite Tri-Squares provide an excellent, economical way for accurately checking the X-Y-Z axes on CNC machines, milling machines, coordinate measuring machines. Lapping all 6 sides maintains flatness, squareness and parallelism.
The Granite Cube finds application in quality, inspection, maintenance, calibration and assembling areas for inspecting and calibrating horizontal or vertical positions. Granite Cubes are also finds application in machine alignment checking and component inspection. Besides, these cubes can be a reference point to accurately measure the straightness, squareness and parallelism of 3 axis of any machine including Co-ordinate Measuring Machine.
GMT Surface plates are manufactured to three grades namely Grade-0, Grade-I & Grade-II. Grade-I & Grade-II plates are artificially seasoned. Consequently, hand scraping ensures maximum local deviation from flatness as per standard at any point on the working surface.
GMT is a Angle plate manufacturer and exporter in India. GMT Cast Iron Angle Plates are heavy duty close grain cast iron to IS: 210 Grade 20. Besides, they are well ribbed to minimize distortion and are artificially seasoned as recommended in IS 2554: 1971.
GMT Cast Iron Angle plates conform to IS 2554:1971 and are available in two grades, Grade-I and Grade-II. They are available in different sizes to meet a wide range of requirements. Besides, Grade-I plates are very carefully hand scraped on to Grade-I limits as per IS: 2554: 1971. Furthermore, Grade-II Plates are machined on all the working surfaces to accuracies conforming to Grade-II limits as per IS: 2554:1971.
Firstly, a Cast Iron Straight Edge is a Machine Tool Accessory, application is essentially in metrology, reconditioning shops and for certain specific applications in tool rooms. Straight edge is primarily for checking straightness. Hence, straightedges find application in the automotive service and machining industry to check the straightness and flatness of machined surfaces in conjunction with surface plates.
The base is made of close grained Cast Iron, heavily ribbed and stress relieved. The checking centres consist of head stock and tail stock. Head stock spindle is of Nickel-Chromium Steel. Centres are tool grade steel.
GMT is one of the oldest manufacturer of bed plates in India. Furthermore, GMT Cast Iron Bed Plates are available with a wide range of T-slot combination and base plate’s shapes and sizes.
Cylindrical squares find application in checking perpendicularity, squareness of machine parts and fixtures. Also, the master cylinders are of high quality, wear resistant hardened steel. Besides, a high precision grinding machine grinds the bottom surface and outer dia (OD) to very high accuracy. Various sizes are available to suit customer requirements.
Granite bonded with metal has resulted in specials for many applications in metrology. As a result the applications include master square for alignment of machining center, Large size Granite Plate, Granite Base Structure for Contact Lens Grinding Machine, Run out Measurement System, fine pitch accuracy granite table, granite structure for Image Processing Machine etc.
