PNEUMATIC AND HYDRAULIC THRUSTERS

Zagar Pneumatic and Hydraulic Thrusters series drilling units are capable of meeting a wide variety of production requirements. Available in three basic thrust sizes, they offer a solid solution for drilling operations. Requiring both rapid advance and controlled feed. The same unit features the choice of pneumatic or hydraulic operation, powered by a three- phase 230/460 V motor.

Zagar Tapping units incorporate a lead screw assembly with our standard drilling units. Tapping units are powered by a reversing brake motor. These serve a wide range of tapping applications, accommodating pitch sizes from 8 to 56 TPI (metric sizes also available) and motor sizes up to 7.5 HP.

FEATURES AND BENEFITS

  • Greater drilling thrust since our double acting cylinder requires no springs for return
  • Efficient power transmission actuated by our involute spline driven spindle
  • Rear support bearing on spindle makes for higher radial load capability and reduced spline wear.
  • Spindle TIR of .0005”
  • Adjustable positive stop with .0005” repeatability for accurate depth control
  • Peck feed options for seep hole drilling in small diameters
  • Quick speed changes made possible through the interchangeable synchronous belt and pulley kits

  • Wide variety of spindle nose options including; Jacob’s Taper, drill head tang drive and Zagar threaded nose for standard Zagar Accessories.
  • Protective guarding for operator safety
  • 1,2 or 3 limit sensor kits for full-back, full-depth, and peck of intermediate positioning control.
  • Adjustable limit sensor cams
  • Standard four limit sensor kit provided for tapping units.
  • Easily interchangeable lead screw and nut assembly, enabling quick changeover of tap pitches (tap units only)
  • Oil mist assembly for automatic lead screw and nut fabrication. (tap units only)
