Tapping Attachment with Integrated Reversing Gear
April 1, 2016
Bilz GNCK tapping attachments feature a modular design to meet the specific requirements of individual machines. They can be used on machining centers with automated tool changers and on special purpose machines. "Because of the integrated maintenance-free reversing gear, changes in direction of the machine spindle are unnecessary," said a company spokesperson.
The length compensation on extension, with a ball release system that operates when in reverse, provides thread depths of 60.15 mm/2.375" up to speeds of 4,000 RPM. The GNCK tapping unit with coolant feed can facilitate pressures up to a maximum of 50 bar/725 PSI.
Precision collets (ER16-GB or ER25-GB) help ensure that the tap is securely clamped, and additional square drivers can be utilized where high torque is being generated, for example when thread forming.
The torque support locks the unit relative to the spindle, thus making automatic tool changing possible. When tool changing takes place, the locking mechanism releases the torque support and allows the tool changing operation to be effected.
"Because of the use of the reversing gears, high tapping speeds are possible, resulting in significantly shorter cycle times compared to conventional tapping," said the spokesperson. "Eliminating spindle rotation reversing in tapping operations increases productivity and reduces machine wear and tear."
