Gear Grinding Centers
CNC gear grinding machines hold tooth profile and lead accuracy on large-module gears used in heavy reduction gearboxes.
Engineered Gearbox Systems
Heavy-Duty Gearboxes Built for Continuous Rolling Duty
From single-stand mill gearboxes to multi-unit drive systems, every unit is engineered to your load, ratio, and installation envelope.

Explore familyIndustrial applications
Built around the duty, not a catalogue shortcut
Custom engineering
A replacement that fits the real installation
Jinxin develops new and replacement transmission systems from field dimensions, installed shaft heights, power and speed data, and the operating duty—not assumptions about a legacy nameplate.
- Footprint and shaft-interface matching
- Load-path and lubrication review
- Project-specific materials and bearing selection
- Independently engineered legacy replacements
Manufacturing flow
Five controlled stages from duty data to dispatch
- 01
Application Review
Load, ratio, interfaces, duty cycle, and installation limits are defined with your engineering team.
- 02
Transmission Design
Gear geometry, shafts, bearings, lubrication, and housing structure are engineered for the operating envelope.
- 03
Precision Machining
Large components move through controlled turning, hobbing, heat treatment, and gear grinding operations.
- 04
Inspection & Assembly
Critical dimensions, tooth geometry, alignment, bearing settings, and running condition are checked.
- 05
Project Handover
The finished drive is prepared with order-specific documentation and export packing requirements.
Factory proof
Large-scale machining in a bright, controlled production environment
Precision Machining Line
A bright, temperature-managed machining bay houses the CNC turning and grinding centers used for shaft and gear-blank finishing.
Heavy Fabrication & Crane Bay
Overhead crane-served bays handle housing fabrication and large-component assembly for heavy gearbox platforms.
FAQ
Before you send a gearbox inquiry
The fastest engineering review starts with motor power and speed, output requirements, duty cycle, and available installation dimensions.
