SPT is a leading manufacturer of Granite Inspection Systems of very high accuracy like Granite / Cast Iron Surface Plates, bench centre, all other products.
SPT has been in the field of Metrology for the past 15 years. We specialize in metrology for design, development and manufacturing of all sort of metrological calibration items.
SPT also manufactures custom built metrology products for Special Purpose Machines.
SPT metrology is a manufacturer and supplier of granite surface plates of grade 00, Grade 0 as per DIN and IS Standards.
Inspection is carried out with a High Precision Electronic Level (Wyler Swiss - Base Size: 200mm, Sensitivity: 0.001MM/M, Range: 20MM/M)
& Spirit Level (ROECKLE – Germany - L.C.: 0.10mm / M) calibrated by an NABL accredited lab at regular intervals
We are manufacturing of Cast Iron Surface Plates to Grade 1 accuracy as per IS 2285-2003.We offer wide variety of cast iron surface plate manufactured in compliance with international quality standards. Extensively used for tool making, inspection, spotting, gauging etc., Hardness between 170 to 220 BHN. Stress relieved to relieve internal stresses. Material confirm to IS 210 2009, Grade FG 260.
Manufactured as per IS: 5980, these cast iron bench centres are utilized in machine shops, tool rooms and standard rooms for checking various parameters such as concentricity , parallelism and true rotation of components.
The bench centres manufactured at our works are made up of close grained cast iron and finished to higher degree of accuracy by hand scrapping.
Granite comparator stands are precision lapped to grade – 0 accuracy. Heavy duty vertical post and adjustable gaging bracket for maximum stability and durability. Base made from finely lapped Granite, housing made from Cast Iron and Pillar from Ground Steel. Main housing slides over the pillar and can be locked at any position.
