Machine Tool Builders

Custom gears and power transmission components for spindle and headstock drives, feed systems, indexing mechanisms and auxiliary drives in machine tools.

We manufacture to customer specifications for CNC machines, lathes, milling machines, grinding equipment and specialized production equipment—for new machine builds, replacement components and existing designs.

Haas CNC vertical mill
Manufacturing range

Spur and internal gears to 36 in.; splines and shafts up to 36 in. long.

Built into the machine

Precision power transmission for CNC machines, lathes & machine tools

Machine tool performance depends on more than motors and controls. Mechanical transmission components inside the machine must repeatedly transmit torque, change speed, synchronize movement and maintain accurate positioning through thousands of operating cycles.

Commercial Gear manufactures custom spur, helical, bevel and miter, worm and internal gears, splines, shafts, sprockets, timing pulleys, worms and lead screws—from compact positioning mechanisms to larger mechanical drive systems, built to customer drawings and specifications.

A gear manufacturer that understands machinery

Why machine tool builders work with Commercial Gear

Machine tool gears operate inside equipment whose purpose is itself to manufacture accurate components. That makes transmission behavior—accuracy, backlash, repeatability—particularly important.

Gear-Focused Experience

Custom gears and related components manufactured since 1946.

Broad Gear Manufacturing Range

Spur, helical, bevel, worm and internal gears plus splines from one manufacturer.

Gear Cutting + CNC Machining

Turning and milling complement gear cutting for more complete components.

Build-to-Spec Geometry

Ratios, shaft centers, bores, hubs and splines made around your machine architecture.

New Builds & Rebuilds

Components for new platforms, repeat models, replacements and machine rebuilds.

Dedicated Inspection

Gear-inspection equipment verifies profile, lead, runout and critical dimensions.

Application Problem Solving

Evaluation of wear, noise, engagement and tolerance problems in existing drives.

OEM & Machine Builder Focus

OEMs and machine tool builders are core markets Commercial Gear serves.

Machine tool gear FAQ

Machine tool gear & component FAQs.

Common questions from machine builders about custom gearing for drives, feeds and indexing systems.

Commercial Gear manufactures spur, helical, bevel and miter, internal and worm gears along with worms, splines, shafts, sprockets, timing pulleys and other custom power-transmission components that can be used throughout machine-tool drive and positioning systems.

Depending on the machine design, gearing may be used within spindle and headstock drives, mechanical feed systems, rotary tables, indexing mechanisms, automatic tool changers, speed-change transmissions and auxiliary drive systems.

Yes. Custom components can be manufactured to customer specifications for established machine designs as well as new equipment programs. Submit available drawings and component requirements for manufacturing review.

Spur and helical gears are commonly used where parallel-shaft power transmission is required. The appropriate gear type, ratio, material and geometry depend on the spindle architecture, torque, speed and operating requirements.

Commercial Gear manufactures worms and worm gears that can be specified for machine mechanisms requiring speed reduction, angular positioning or compact right-angle transmission arrangements.

Yes. Commercial Gear combines gear-cutting processes with CNC turning and milling capabilities for custom power-transmission components such as blanks, hubs, shafts and related machined features.

Commercial Gear lists both internal and external splines and shafts among its manufacturing capabilities, supporting torque-transmission connections used in industrial machinery.

Where possible, provide the component drawing, gear geometry, material, quantity, dimensional tolerances and any known mating-component or application requirements. For replacement applications, include as much information about the existing component and machine as available.
