CNC Machining Solutions forPrecision Transmission Components
Precision-machined gears, shafts, splines, couplings, and transmission components for demanding motion systems.
We machine spur gears, helical gears, bevel gears, worm drives, spline shafts, planetary carriers, and couplings for servo systems, industrial drives, and precision motion applications — with gear inspection reporting and heat treatment coordination.
The manufacturing pain points our customers in this industry face most often — and how we address each one before it becomes a problem on your assembly line.
Tight Tolerance Control on Transmission Features
Servo and precision motion applications require AGMA Class 10 or better — pitch error, runout, and tooth profile deviation all controlled within specification. Standard turning alone is not sufficient for gear-quality requirements.
Accuracy Requirements for Mating Parts
Transmission systems involve multiple mating parts — gear pairs, shaft-hub interfaces, spline couplings. Each part must meet its individual tolerance so the assembled system achieves the required backlash and load-sharing performance.
Wear Resistance and Stable Performance
Gears and spline shafts accumulate millions of load cycles. Heat treatment, post-heat grinding, and surface treatment must be executed correctly to deliver the designed wear life — not just adequate first-article dimensions.
Consistency Across Repeat Batches
Production quantities of transmission parts must be dimensionally consistent from batch to batch. Gear quality and shaft fit variations between batches cause assembly issues and field reliability problems for your end customers.
Gears, shafts, splines, couplings, and planet carriers for servo drives, industrial gearboxes, and precision motion systems. Every precision gear ships with a full gear inspection report.
Specific machining, quality, and project support capabilities that match what this industry actually demands — not generic claims.
Gear Inspection on Every Precision Order
Every precision gear receives a full profile, helix, pitch, and runout inspection report. This is not sampling — it is 100% inspection of critical gears with results you can use for your own incoming quality records.
Better Fit Control for Shaft and Hub Interfaces
We hold spline shaft and bore fits to DIN 5480 / ISO 4156 standards with the consistency that gives correct torque transmission and predictable backlash — reducing the assembly adjustment that wastes production time.
Heat Treatment Loop Managed In-House
Pre-heat cutting allowance and post-heat grinding are managed as a coordinated single process. No tolerance stack from multi-supplier handoffs. Final dimensions are correct after hardening, every batch.
Stable Repeatability from Sample to Production
Locked gear cutting programs and inspection fixtures from first article through production. Gear quality class is maintained across every batch — not just demonstrated on the first article.
From your first drawing to stable production delivery — a clear process that keeps your development and production schedule on track.
Gear Data & Drawing Review
Submit your gear drawing with module, pressure angle, helix angle, accuracy class, and material. We review for cutting feasibility and heat treatment compatibility before quoting.
Quote with Inspection Plan
You receive a quote including cutting process, heat treatment, post-heat grinding, and inspection protocol — complete process plan, not just a unit price.
First Article with Gear Inspection Report
First gears cut, heat treated, ground, and inspected. You receive a full gear inspection report (profile, helix, pitch, runout) before bulk delivery.
