"JPT" electroplated diamond & cubic boron nitride (CBN) mounted points (grinding pins) are manufactured in a state-of-the-art plant, incorporating automatic process control & unique plating technology. Specially selected grades of blocky natural or synthetic diamond & CBN are used for our pins. This ensures smooth free-cutting action with minimal heat buildup & long service life. Our unique plating process provides exceptionally high bond strength, reducing the risk of premature pull-out of diamond / CBN abrasive grains. The blanks are made of medium carbon steel, which is tougher than ordinary mild steel, in order to minimize bending of the shank during use.
The pins can be used for external & internal grinding of a wide variety of materials. Diamond pins are used for fibre-glass, bakelite (printed circuit boards), carbides, ferrites, graphite, ceramics, glass, etc. CBN pins are used for high speed steels, tool & die steels, cast irons, hardened steels (45 Rc & up), etc.
Standard pins are available in a range of 1mm to 30mm diameter. Alternatively we can manufacture custom made pins to your specifications, and we can also undertake diamond/ CBN coating of blanks supplied by you. |
