Coupling sleeve machining centers

USC 27

  • Spindle diameter, max.: 290 / 380 mm | 11.5 / 15 in
  • Nominal diameter: Inch 4 ½ – 13 ⅜
  • X-axis travel: 300 mm | 12 in

Horizontal Center-Drive lathe Machine for the complete machining of couplings and tool joints

The USC 27 horizontal coupling machine center for the machining of couplings and tool joints with a nominal diameter of 4 1/2 - 13 3/8" inches.

USC 27 – High quantities of the highest quality

The USC 27 center-drive lathe machine stands for efficiency. It impresses through its capability to simultaneously complete-machine both sides of coupling sleeves and tool joints with international threads, like API and GOST, or threads of proprietary standard. The machine base is made of the high-quality polymer concrete MINERALIT®, a material of outstanding damping quality.

The EMAG 4-station flat-bed turrets are mounted on the compound slides to the right and left of the center drive headstock. The high rapid traverse speeds of the compound slides and the automatic workhandling system minimize idle times. Rapid-reaction, frequency-controlled, maintenance-free AC motors and high-precision ground ball screws control the movement of the slides on their linear guideways.

Advantages USC 27

  • The ideal platform for multifunctional manufacturing solutions – single- and multi-spindle – up to fully automated production systems
  • Very sturdy, vibration-resistant machine base in high quality MINERALIT® polymer concrete
  • Powerful, direct-driven spindle motors
  • Direct-indexing tooling systems
  • High-precision, preloaded linear roller guides for maximum precision and great dynamic
  • Absolute position feedback systems for constantly maintained precision
  • Fluid-cooled, temperature-controlled main assemblies – including spindle motor, tooling systems and electrical cabinet – form the basis for high quality workpieces
  • Safe, wear resistant, maintenance free machining area
  • Ideal chip flow conditions, with the chips falling unhindered to the bottom, causing no damage
