The more advanced programmable lead guide gear shaper ST40A, incorporating a CNC relieving mechanism, realizes the programmed shaping of tapered and/or crown gears through the use of a newly developed NC relieving mechanism.

Gear shaper ST series

Feature

Programmable Lead Guide with CNC Relieving (Optional)

  • The programmable lead guide is the most important feature of the ST series. It incorporates advanced high-speed and high-precision NC control technologies to allow for spindle movement based on the helix angle of the cutter. This enables flexible production of helical gears with either a left-hand or right-hand helix at a different helix angle, in addition to spur gears.
  • The ST40A's CNC relieving mechanism enables the shaping of tapered and/or crown gears, for the production of gears with higher added value.

High Flexibility to Support All Gear Types

  • The built-in software simplifies the production of a variety of special gears including double-gear clusters.
  • The wide cutter stroke (30 to 600 strokes/min) supports both productivity-focused high-speed cutting and low-speed cutting for rigid gears.

High Flexibility

  • The quick return function (optional) improves the spindle return speed for cycle time reduction, thus eliminating the need for changing the cutting conditions.

Easier Operation

  • The built-in programming software automatically sets cutting conditions, so you can cut gears only by entering the specifications of the workpiece and cutter.
  • The operation panel uses easy-to-use pushbutton switches and a high-visibility liquid crystal display (LCD). On the LCD, the built-in software displays dedicated conversational programming screens based on Microsoft Windows graphical user interface for user friendly operation.
  • The swivel type operation panel improves operability.
