Custom Rubber Bushing Components

FlexiTurn manufactures custom precision CNC-machined grooved rubber bushings, delivering flash-free sealing grooves, strict bore-to-OD concentricity ($\le 0.015\text{ mm}$), and repeatable interface dimensions for press-fit resilient mounts and dynamic seals. Precision CNC turning and trimming resolve material elasticity, preventing cutting deflection, edge tearing, and clamping distortion across high-wear elastomeric components.

Precision Machining & Processing Capabilities

• Single-Setup Rotational Turning: Internal bores, outer diameters, circumferential lubrication/seal grooves, and end-face chamfers are turned in a single setup using custom vacuum or low-force collet chucking, eliminating re-clamping runout and preventing part distortion.
• Cryogenic Machining Options: For ultra-soft compounds (Shore A < 50) or intricate groove geometries, temporary cryogenic freeze-stabilization allows high-speed razor/diamond milling without edge tearing or thermal degradation.
• Edge & Groove Quality Control: Micro-shear rotary tooling and calibrated cutting feeds produce clean, burr-free groove edges and uniform wall thicknesses, eliminating downstream sealing failure risks.
• Secondary Feature Execution: Precision 3-axis CNC milling, side slotting, and hole punching performed on dedicated soft-material workcells for secondary-machined molded blanks.

Quality Assurance & Material Traceability

Every elastomeric order processed under FlexiTurn’s ISO 9001:2015-aligned quality system undergoes rigorous soft-material verification:

• 100% Material Traceability: Compound Batch Certificates, Durometer Logs, and Material Test Reports (MTR) provided with every production lot.
• Non-Contact Optical Inspection: Non-contact optical CMM verification guarantees accurate dimensional profiling without compressing flexible part features during measurement.
• Optical Edge Inspection: 100% microscopic inspection of circumferential grooves and sealing lips to verify zero flash, tearing, or micro-cracks.

Why Choose FlexiTurn

• Specialized Elastomer Machining Know-How: Dedicated workcells, ultra-sharp shear tooling, and deformation-free workholding effectively defeat material elasticity, edge tearing, and tool deflection.
• Deformation-Free Clamping: Custom vacuum fixtures and low-pressure soft collets maintain strict concentricity without distorting thin-wall cylindrical bushings.
• 100% In-House Production: Raw compound verification, secondary turning, groove profiling, flash removal, and optical CMM inspection are managed entirely on-site with zero subcontracting.
• Complimentary 24-Hour DFM Review: Technical evaluations analyze groove corner radii, draft angles, and wall stability to eliminate production bottlenecks and lower unit costs.
• Strict Intellectual Property Protection: All CAD models, customer specifications, and compound formulations are secured under encrypted internal protocols, with NDAs executed prior to data transfer.
