Why This Matters for Small Gears

Micro gears leave little margin for deformation, burrs or unstable inspection. Early drawing review helps reduce production risk before tooling, process planning and batch manufacturing.

CNAS Lab Capability

In-house inspection and testing capability supports dimensional, material, environmental and functional verification needs.

Gear Cutting and Small-Part Machining

Representative equipment includes Tokyo Wako H102C / 120A hobbing machines, Mikron 102-0.5, Ningjiang YG3612 / YKJ3610, Baocheng T-YG3603, Schaublin SBL series lathes, Hardinge T42 / ST-216B and MAZAK INTEGREX i-250 for small precision parts.

Heat Treatment and Surface Finishing

When drawings call for hardened steel gears, wear resistance or corrosion protection, MH can plan vacuum quenching, vacuum tempering, vacuum annealing, plating, passivation, blasting or other surface routes according to the material and drawing notes.

Finishing for Bores, Shafts and Tooth Edges

Grinding, EDM, low-speed wire cutting and deburring steps are selected when the part has small bores, thin walls, slots, shoulders or tooth edges that cannot be treated like ordinary machined components.

Inspection for Customer Drawings

ZEISS CMM, ZEISS CONTURA, Mitutoyo LH-600E/EG height gauge, Mitutoyo SJ210 roughness tester and toolmaker microscopes support dimensional checks, surface finish review and key feature verification before delivery.

Drawing and Gear Data

Send the 2D drawing, 3D model if available, module, tooth count, pressure angle, accuracy requirement, datum, tolerance notes and any mating gear or assembly information.

Material, Process and Quantity

Include material grade, heat treatment, surface treatment, hardness, sample quantity, expected batch quantity and whether the part is for prototype validation or stable production.

Can MH review a drawing before quoting?

Yes. MH can review module, tooth count, tolerance, material, heat treatment, datum and inspection points before confirming the production route.

Can you manufacture prototypes and batches?

Yes. The process can start from drawing review and sample validation, then move toward repeatable batch production after key dimensions and inspection standards are confirmed.

What makes micro gears difficult?

Small teeth, thin sections, integrated shafts, hardened surfaces, burrs, runout and inspection access can all affect assembly quality if they are not considered early.

Do you accept confidential drawings?

Yes. Customers can send masked drawings for initial discussion, and sensitive project information can be handled according to the customer's confidentiality requirements.
