Custom Gear Manufacturing
Drawing-based CNC machining for metal and engineering-plastic gears used in prototypes, low-volume orders, and repeat production.
Gear Types for Different Motion Systems
Select the closest structure, then define tooth data, shaft arrangement, interfaces, load, speed, lubrication, and required accuracy.
Spur & Helical Gears
External gears for parallel-axis drives, from direct engagement to smoother helical motion.
Internal & Ring Gears
Compact internal-tooth and annular structures for planetary and circular assemblies.
Bevel Gears
Angle-drive gears for intersecting or offset shaft arrangements.
Worm Gears
High-ratio worm and wheel sets for skew-axis transmission.
Gear Racks
Linear tooth elements paired with pinions for controlled travel.
Gear Shafts & Compound Gears
Integrated teeth, shafts, hubs, and multiple stages with controlled datum relationships.
Gear Materials, Grades and Treatments
Choose metal or engineering plastic first, then compare grades by tooth strength, fatigue life, wear, corrosion, lubrication, and dimensional stability.

From Gear Drawing Review to Protected Delivery
The production route is planned around datum control, tooth generation, treatment timing, and inspection checkpoints.
Confirm the specification
Review tooth data, material, treatment, quantity, and records.
Set datums and sequence
Define workholding, allowances, and process order.
Machine the geometry
Produce blanks, bores, hubs, shafts, and tooth features.
Verify and protect
Check specified features and protect teeth for shipment.
Prepare a Complete Gear Drawing Package
Clear technical inputs reduce assumptions and help confirm the process, inspection scope, and delivery plan.
Tooth profile, lead, pitch, backlash, and gear-grade verification are confirmed after review of the applicable standard and inspection method.
Custom Gear Project Questions
What information is needed for a custom gear quote?
Provide gear type, module or DP, tooth count, pressure angle, interfaces, material, treatment, quantity, and required accuracy.
How long does custom gear production take?
Lead time depends on material, geometry, tooling, heat treatment, inspection, and quantity. Complete drawings and prompt sample approval shorten the schedule.
How can custom gear manufacturing cost be reduced?
Use standard modules, practical tolerances, and available materials. Control only functional features and request a DFM review before production.
How is the correct gear material selected?
Selection follows load, speed, duty cycle, lubrication, temperature, corrosion, noise, and target service life.
How is gear accuracy verified?
Specified bores, faces, runout, and tooth characteristics are inspected against the drawing and applicable gear standard using the agreed method.
