Custom CNC Machined Bronze Bushings

FlexiTurn manufactures precision bronze sleeve bushings like the components shown above through our full-spectrum CNC machining services. We do not carry off-the-shelf standard bushing inventory — every part is produced to your exact CAD dimensions and material requirements, delivering finished, dimensionally verified bronze wear components tailored to your application.

Advanced Processing & Precision Machining Capabilities

• High-Precision Turning & Boring: CNC lathe turning and boring centers ensure strict wall-thickness uniformity, accurate bore concentricity, and flat flange seating faces.
• Internal Micro-Grinding & Surface Finishing: OD/ID precision grinding capabilities achieve bore tolerances down to ±0.01 mm and smooth surface finishes of Ra 0.4–0.8 μm for reduced wear and optimal lubrication retention.
• Complex Feature & Grooving Operations: Custom CNC toolpaths for oil retention grooves (figure-8, spiral, annular), radial lube holes, keyways, and chamfered entry lead-ins.
• Comprehensive Bronze & Brass Material Processing: Specialized machining across tin bronze (C90500/C90700), aluminum bronze (C95400/C95800), phosphor bronze (C51000/C54400), leaded bronze, and high-tensile brass.

Why Choose FlexiTurn for Custom Bronze Bushings?

Integrated Turning & Grinding Under One Roof: All turning, boring, grinding, and deburring operations are performed in-house on our own precision equipment. Eliminating third-party sub-contracting ensures tighter process control, faster lead times, and direct factory pricing.

Free 24-Hour DFM Engineering Review: Every submitted CAD file receives a complimentary Design for Manufacturability evaluation within 24 hours. Our engineering team assesses press-fit tolerances, wall integrity, lubrication channel geometry, and material selection to optimize costs and prevent field failures.

Rapid Toolless Prototyping & Zero MOQ: Skip expensive casting patterns and long lead times! We machine functional prototype bushings directly from certified bar stock in 1–3 business days, with zero minimum order quantity for both initial trials and production runs.

Single-Source Multi-Material Capability: Beyond bronze and brass, FlexiTurn machines aluminum, stainless steel, alloy steel, and engineering plastics in the same facility, making us a single-source supplier for multi-material shafts, housings, and bushing sub-assemblies.

ISO-Aligned Quality Assurance: All manufacturing operations align with our ISO 9001:2015 quality management system. Every order includes dimensional inspection reports, surface roughness verification, and raw material batch certifications with RoHS/REACH compliance.

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.
