Custom CNC Machined Brass Worm Gears

FlexiTurn provides custom CNC turning for tin bronze worm shafts used in high-precision rotary drives, robotics, and industrial motion control systems. Machined from solid tin bronze bar stock in a single setup, these components integrate full-profile worm threads, a precision through-bore, and finished end faces for smooth torque transmission and low-friction operation.

To minimize tooth profile distortion, lead error, and concentricity drift common in non-ferrous thread turning, FlexiTurn applies validated cutting parameters, specialized tool geometries, and single-setup machining. Our process controls lead error and maintains concentricity within 0.01 mm TIR, supporting GD&T requirements and repeatable assembly fit across production runs.

Why Choose FlexiTurn for Custom CNC Turning

Single-Setup Geometric Accuracy

All rotary and helical features are machined in a single workholding setup, eliminating cumulative error from re-fixturing. This delivers consistent concentricity, lead accuracy and tooth alignment across every part — a level of geometric stability multi-operation machining cannot match. We do not compromise accuracy for throughput.

Drive-Specific Quality Control

Quality control follows ISO 9001:2015 protocols with inspection criteria tailored to rotary drive components: 100% lead and profile verification for worm features, in-process concentricity runout checks, full CMM dimensional validation on final parts, and complete material traceability from raw bar to finished component. Material certification and inspection reports are provided with every shipment.

Consistent Batch-to-Batch Repeatability

We use locked, validated process parameters for every part number, not discretionary operator adjustment. This ensures dimensional, tooth profile and surface finish consistency from the first piece to the last, reducing customer incoming rejection rates and assembly fit issues. No batch drift, no unexpected deviations.

Flexible, Reliable Order Fulfillment

We support prototype, design validation and production volume orders with transparent lead times and scheduled delivery. Our production scheduling prioritizes engineering change responsiveness and urgent line-maintenance orders, so your development and production schedules stay on track. No overpromising, no uncommunicated delays.

For all custom CNC turned mechanical and drive component requirements, submit your engineering drawings and project specifications to FlexiTurn. We deliver precise, repeatable, traceable precision machining services from prototype through full production.

Q1. What types of machining services do you offer?

We provide comprehensive CNC turning and milling services. FlexiTurn machines are equipped with 8-station programmable turrets and support both turning and 5-axis milling operations, making them suitable for everything from simple cylindrical parts to complex multi-axis components.

Q2. What materials can you work with?

We machine a wide range of materials including carbon steel, stainless steel, aluminum, plastics, and other engineering-grade materials. If you have a specific material in mind, just send us your requirements and we'll confirm feasibility.

Q3. What is your typical lead time?

Lead times vary depending on part complexity, quantity, and material availability. For prototypes and small-batch runs, we typically deliver within 5–10 business days. For high-volume production, we'll provide a customized schedule after reviewing your drawings. Contact us with your project details for an accurate timeline.

Q4. How do you price your services?

Pricing is based on several factors: material cost, machining time, tooling requirements, setup complexity, and order quantity. We offer competitive rates for both low-volume prototypes and high-volume production runs. Request a quote with your CAD files or drawings and we'll get back to you within 24 hours.

Q5. What quality control measures do you have in place?

We follow strict quality control procedures throughout the machining process. Our CNC systems support programmable precision down to 1 μm, ensuring high accuracy and repeatability. Every batch undergoes dimensional inspection before shipping, and we can provide inspection reports upon request.
