Internal & Involute Spline Cutting

  • Internal spline cutting and shaping
  • ANSI and DIN involute spline profiles
  • Broaching, EDM, and shaping support

Spline Hobbing Services

  • External spline hobbing for shafts
  • Rapid Production and low-volume runs
  • Multiple alloy steel capabilities

Spline Grinding Services

  • Finish grinding and surface correction
  • Improved fit and concentricity
  • Repair and reconditioning support

Spline Shaft Manufacturing

  • Complete spline shaft machining
  • Manufacturing from prints or samples
  • Reverse engineering support

Internal & External Spline Manufacturing

Internal and external spline manufacturing for gearbox hubs, couplings, spline shafts, and torque transmission components. Manufacturing support is available from drawings, CAD models, samples, or reverse engineered parts.

Spline cutting methods include shaping, spline hobbing, EDM, and milling based on spline geometry and application requirements.

Spline Repair and Reverse Engineering

Spline repair and reverse engineering support for worn, damaged, or obsolete spline components. Existing parts can be evaluated to restore geometry, fit, and interface compatibility when drawings are unavailable.  Repair & Reconstruction Includes:

  • Restore exact geometry and surface finish
  • Re-engineer obsolete parts from worn samples
  • Ensure perfect fit and interface compatibility
  • Save thousands compared to OEM replacement delay
