Die Sets

H & J Associates offers Die Sets. Different variations of standard models for various applications are available. All steel Top and Bottoms are machined and grounded to an accuracy of 0.00025 - 0.0005. Pillar and bushes are made from good quality steel, hardened 58/ 60 Rc and grounded to B. S. specifications. Ball Bearing Die Sets: Standard Die sets are manufactured to a very close limit, but where the nature of work requires extreme accuracy or where high speed presses are used, the use of precision die sets fitted with ball bearing bushes is recommended. Ball Bearing Bushes: Made from specially treated solid alluminium alloy, Ball bearing bushes are invaluable in high production presses where precision is vital. The close helical pattern of balls fitted in the cage is specially created to increase lubrication resulting in smooth, frictionless movement. This freedom of movement facilities are the accurate setting of punches and dies. Other applications for Ball bearing bushes are those involving moving loads freely over a distance as movement involving both linear and rotary motion.
