2D CNC Machinery has added S&T Dynamics competitively priced range of high production gear cutting machinery and related automation equipment to its portfolio of metal cutting CNC machining centres, cell and system technology.


Said Director David Holden: “The S&T Dynamics agency is an important addition to 2D CNC’s portfolio of high quality and specialist CNC process equipment and like the existing product ranges we represent, has very strong links to leading manufacturing enterprises around the world.”


S&T Dynamics, previously trading as Tongil Heavy Industries Co., until 2005 is a leading manufacturer of automotive and military powertrain, axles and transmissions that include gearboxes for helicopters, and wind-power applications, dual-clutch transmissions and hybrid power trains. It also supplies both civil and military aerospace, medical and general sectors such as motorsport and has been listed on the Korean stock market since 1976. It has a turnover of $517 million and employs 1,200 people of which almost a third of the office based workforce are engineers.  


As the company is a precision gear manufacturer it has developed and builds its own gear cutting machine tools which is a sub-division of its larger global CNC machine tool build operations that include its own castings, production and build facilities.  Machines can be supplied as complete turn-key packages including production of crowned gears, tapered gears, skiving and deburring.  In addition, associated automation can include ring loaders, stockers, conveyors and robotic loading.


The gear cutting machines include hobbing, shaping and shaving processes plus a range of gear chamfering and deburring equipment.  Initially 2D CNC will be marketing and supporting the high speed hobbing machine range.  These machines start at the H80 which has a maximum capacity of 80 mm, module M2.5 with a high speed (3,000 revs/min) zero backlash 7.5 kW hob spindle to the H500 with a capacity of 500 mm.  The H500 has a workpiece module M12 and a 25.5 kW spindle.  


The range of machines feature zero-backlash, high rigidity torque motors for the table rather than the more traditional worm-drive system.  Each machine has control options of Siemens 828D or Fanuc 18iMB.
