Precision CNC Machining Bronze Parts

FlexiTurn manufactures precision bronze flanged bearing housings like the parts shown above through our end-to-end custom CNC machining services. FlexiTurn does not carry off-the-shelf standard parts — every component is custom machined to your exact CAD specifications, delivering finished, dimensionally verified bronze wear and bearing parts tailored to your specific application conditions.

Advanced Processing & Multi-Axis Machining Capabilities

• Precision Boring & Bearing Seats: High-speed CNC boring centers deliver tight bearing-fit tolerances down to ±0.01 mm, maintaining strict bore roundness and wall uniformity.
• Multi-Axis Milling & Hole Patterns: Integrated 4-axis CNC milling for precise mounting bolt hole arrays, radial lubrication ports, circumferential notches, and locking pin slots.
• Flange Flatness & Perpendicularity Control: Advanced face-milling toolpaths ensure precision parallelism and true perpendicularity between the locating flange face and central bore axis.
• Comprehensive Bearing Bronze Processing: Specialized machining across tin bronze (C90500/C90700), leaded bearing bronze, aluminum bronze (C95400), and phosphor bronze (C51000/C54400) with complete material traceability.

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.
