GMT METROLOGY PRODUCT RANGE
GMT manufactures surface plates, angle plates, box angle plates, straight edges, bench centers, 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 which conforms to DIN 876 – 84 is of laboratory grade, GRADE 0 is of inspection grade, GRADE 1 which is of tool room grade, and GRADES 2 & 3 for use in shops for general inspection.
GMT SIX-FACE MASTER SQUARES can be used to check of squareness or parallelism of any component. Master squares have six finished faces.
GMT GRANITE STRAIGHT EDGES
GMT GRANITE STRAIGHT EDGES are used to inspect flatness and parallelism between two machine parts or components. Lapping both top and bottom faces ensures flatness. Consequently, straightness and parallelism can be achieved to conform to 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 six sides maintains flatness, squareness, and parallelism.
GMT Granite Cubes are used in quality control, inspection, maintenance, calibration, and assembling areas for inspecting and calibrating horizontal or vertical positions. Granite Cubes also find applications in machine alignment checking and component inspection. Besides, these cubes can be a reference point to accurately measure the straightness, squareness, and parallelism of three axes of any machine, including the Coordinate Measuring Machine.
CAST IRON SURFACE PLATES 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 CAST IRON ANGLE PLATES are made of heavy-duty, close grain cast iron to IS: 210 Grade 20. 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 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.
THE GMT CAST IRON STRAIGHT EDGE
THE GMT CAST IRON STRAIGHT EDGE is a Tool Room Accessory. Its application is essentially in metrology, reconditioning shops, and for certain specific applications. The Straight Edge is primarily for checking straightness. Hence, The Straight Edge is used in the automotive service and machining industry to check the straightness and flatness of machined surfaces in conjunction with surface plates.
The base is of close-grained Cast Iron, heavily ribbed and stress relieved. The checking centers consist of headstock and tailstock. The headstock spindle is of Nickel-Chromium Steel. Centers are tool-grade steel.
GMT CAST IRON BED PLATES: GMT is one of the oldest manufacturers of bedplates in India. Furthermore, GMT Cast Iron Bedplates are available with a wide range of T-slot combinations and base plate shapes and sizes.
MASTER CYLINDERS-CYLINDRICAL SQUARES:
CYLINDRICAL SQUARES are used to check the perpendicularity and squareness of machine parts and fixtures. Also, the Master Cylinders are of high quality, wear-resistant hardened steel. Besides, high-precision grinding machines are used to grind the bottom surface and outer diameter (OD) to very high accuracy. Various sizes are available to suit customer requirements.
SPECIAL APPLICATIONS OF GRANITE IN PRECISION MANUFACTURING AND MACHINE ASSEMBLY
Granite bonded with metal has resulted in specials for many applications in metrology. As a result, the applications include Master Squares for alignment of machining center, Large size Granite Plates, Granite Base Structures for Contact Lens Grinding Machine, Runout Measurement Systems, Fine Pitch Accuracy Granite Tables and granite structures for Image Processing Machines.
