Turn-Mill Machining a C63000 Aluminum Bronze Worm Gear for Automation Equipment
Richconn produced a custom irregular worm gear made from C63000 aluminum bronze for automation equipment. The project required precise tooth geometry, fine machined texture, 0.02 mm face runout control, and stable gear accuracy through MAZAK turn-mill machining.
Custom Irregular Worm Gear with Tight Tooth Accuracy and Runout Requirements
This project involved the turn-mill machining of a custom gear worm component for automation equipment. The part was made from C63000 aluminum bronze and required a smooth concave tooth area, controlled tooth profile accuracy, and face runout control.
For transmission components used in automation equipment, small errors in tooth profile, inner hole keyway position, surface finish, or runout can affect meshing quality, transmission noise, wear performance, and long-term machine stability.

Why This Worm Gear Was Difficult to Machine
The customer required a custom irregular gear with IT14/2 tolerance requirements and 0.02 mm face runout. Because the tooth form was not a simple standard geometry, the process needed to control both tooth accuracy and surface texture.
If the machining marks were too coarse or the equipment accuracy was insufficient, the tooth precision and face runout would not meet the required standard.
Main Manufacturing Risks
- Irregular tooth geometry required high equipment stability and process control.
- Coarse machining marks could affect tooth accuracy and meshing quality.
- Face runout needed to be controlled within 0.02 mm.
- The inner hole keyway needed accurate processing to support assembly fit.
- Transmission parts require stable accuracy to reduce noise, wear, and fit issues.
The Core Difficulty Was Tooth Accuracy, Surface Finish, and Runout Control
The main challenge was not only cutting the gear shape, but also maintaining fine tooth surface quality and reliable geometric accuracy. For an irregular C63000 aluminum bronze worm gear, the machine tool, cutting sequence, finishing allowance, and inner keyway machining method all affect the final transmission performance.
| Tooth Geometry Risk | The irregular gear profile required stable machining to maintain the intended tooth shape and meshing relationship. |
|---|---|
| Surface Finish Risk | Fine machined texture was required because rough tool marks could affect tooth accuracy and fit quality. |
| Runout Requirement | The customer required 0.02 mm face runout, which demanded stable workholding and finishing control. |
| Keyway Accuracy | The inner hole keyway had to be accurately processed to support assembly and transmission alignment. |
How We Controlled Tooth Profile Accuracy and Runout
Richconn used a MAZAK turn-mill machining process to combine turning, milling, and precision finishing in a controlled process route. The gear teeth were machined in stages, and the inner hole keyway was finished using slow wire EDM to protect dimensional accuracy.
MAZAK Turn-Mill Machining
A MAZAK turn-mill machine was selected to support the precision machining requirements of the irregular gear geometry.
Rough Machining with 0.5 Allowance
The part was rough-machined first with a 0.5 mm allowance, reducing finishing risk and preparing the gear area for final machining.
Secondary Tooth Finishing
The tooth area was finished in the second machining stage to achieve the final tooth geometry and smooth concave tooth surface.
Slow Wire EDM for Keyway
The inner hole keyway was processed by slow wire EDM to achieve stable internal feature accuracy.
Final Accuracy Verification
The finished gear was checked against tooth accuracy and runout requirements before delivery.
Transmission-Focused Control
The process focused on tooth accuracy, fit clearance, surface quality, and wear-related performance for long-term stable operation.

What Buyers Should Know About Custom Worm Gear Machining
Custom worm gears and irregular gear components are not judged only by whether the shape can be machined. Tooth profile accuracy, surface finish, runout, keyway accuracy, fit clearance, and material selection all influence the final transmission quality.
For automation equipment, using C63000 aluminum bronze combined with precision turn-mill machining can support better wear resistance, smoother meshing, and more stable long-term equipment operation when the process is properly controlled.
Richconn’s Practical Experience
- Select stable turn-mill equipment for irregular gear geometries.
- Use staged roughing and finishing to protect final tooth accuracy.
- Control tool marks because tooth surface texture affects fit and transmission quality.
- Use slow wire EDM for internal keyway features when precision is critical.
- Verify both tooth accuracy and runout before delivery.

FAQ About C63000 Aluminum Bronze Worm Gear Machining
Why is C63000 aluminum bronze used for custom worm gears?
C63000 aluminum bronze is often selected for transmission-related parts because it can provide strength, wear resistance, and stable performance in mechanical contact applications.
Why are tool marks important in worm gear machining?
Tooth surface texture affects meshing quality, fit, wear behavior, and transmission noise. Coarse tool marks can make it harder to meet precision and performance requirements.
Why was slow wire EDM used for the inner hole keyway?
Slow wire EDM can provide stable accuracy for internal keyway features, especially when the keyway must support proper assembly and transmission alignment.
Can Richconn machine similar custom gears or transmission parts?
Yes. Richconn can support custom machining of irregular gears, worm gears, shaft parts, bronze transmission components, and automation equipment parts based on drawings, material requirements, tolerances, and quantities.
