Quality, Reliability & Values Since 1968
Industrial & Mining Tools Co utilizes modern equipment, which performs all the turning, milling and drilling operations. In the machine shop, the equipment is kept thoroughly up-to-date and some machines have been customized for production of certain components. Others have been adapted for particular requirements, and indigenously developed jigs and fixtures are extensively employed. The latest machines allow skilled personnel to hold dimensions to very close tolerance. All parts are subjected to quality inspection using air gauges and other electronic and standard quality control processes. Super precision internal and external grinding provides the high tolerance finishes and accurate fits that are so critical for today's mining and construction tools.
The only way to ensure the necessary accuracy is to start right. Our tool room is therefore kept busy making jigs and fixtures, taps, hobs, broaches and other special tools, and gauges for use in the machine shops and inspection rooms. Equipment is of the finest obtainable and includes measuring instruments of almost incredible accuracy.
The spare parts of our Pneumatic tools are manufactured only from premium quality raw-materials. The valves, pistons and other moving parts are made from shock resistant alloy steels and then heat-treated to a specified Rockwell hardness for toughness and durability. The heat treatment of parts are carried out in furnaces of many types - each chosen as being the most suitable to obtain consistent results with the components for which it is used - and by methods devised by our metallurgical staff. The carburizing heat treating process results in parts which have hard surfaces and resilient cores that withstand and dampen shock waves.
Accuracy is of equal importance. If a Pneumatic Rock Drill is to be efficient as well as fast, working parts must be close fitting. Another reason for extreme accuracy is the necessity for perfect interchangeability. All components are made in large batches and after inspection, passed into stores from where they are drawn for assembling complete machines or for despatch as spares. There must be no doubt as to whether a part will fit - the assembler at the works or the rock drill fitter on a mine does not have to pick and choose or use a file to make a part go into its correct position. An IMT tool can be assembled in a few minutes from components taken at random from stores.
