OEM CNC Machined Brass Parts

Precision Brass Machined Guide & Mounting Block

FlexiTurn delivers custom precision machined brass and copper alloy components engineered for self-lubricating guidance, locating, and connecting functions in precision motion systems, instrumentation, and fluid control actuators. Leveraging the excellent machinability of free-cutting brass, we produce tight-tolerance small-form parts with consistent surface finish and geometric accuracy, supporting low-volume prototypes through mid-volume production runs.

Standard Grades: C36000 (H62) free-cutting leaded brass; C93200 bearing bronze available for high-wear applications.

Traceability: Full material traceability with certified mill test reports (MTRs) provided per batch.

Compliance: Compliant with ASTM B16 / EN CW614N material standards; RoHS-compliant lead-free brass options available upon request.

CNC Turning: Precision turning for all cylindrical features, including locating bosses and inner bores, with in-process concentricity control.

3-Axis & 4-Axis CNC Milling: 3-axis milling for contoured profiles, slot features, and mounting faces; 4-axis indexing for complex circumferential features.

Drilling & Tapping: CNC drilling, countersinking, and reaming for all mounting and locating holes.

Deburring: Full deburring and edge break on all contours, holes, and slots; zero residual burrs on mating surfaces.

Precision Grinding: Optional finish grinding for ultra-tolerance mating surfaces.

Dimensional Tolerance: IT6 – IT8 standard grade; IT5 achievable with finish grinding.

Bore-to-Boss Concentricity: ≤0.01 mm.

Surface Roughness: Ra 0.8-1.6μm  as-machined; Ra 0.4 μm with ground finish.

Inspection: 100% feature verification according to customer drawing specifications.

Automation Machinery: Actuator guide blocks, valve actuator connecting parts, precision locating mounts for production line equipment.

Robotics: End-effector mounting bases, low-speed joint guide components, auxiliary actuation locating parts for industrial robots.

Medical: Precision actuation components for diagnostic equipment, non-implantable device structural parts, fluidic actuator blocks.

Automotive: Electronic actuator structural parts, transmission auxiliary guide sliders, precision lock components for vehicle systems.

Telecom: Conductive mounting seats for passive RF devices, structural support parts for communication modules, internal locating connectors for base station equipment.

Consumer Electronics: Precision shafts, latch structures, and thermal/conductive connectors for high-end 3C products.

Semiconductor: Peripheral actuator guide blocks and auxiliary connecting parts for non-cleanroom semiconductor equipment.

Aerospace: Non-load-bearing auxiliary instrument components for ground support equipment (GSE / non-flight-critical applications only).

Produced strictly under an ISO 9001:2015-certified quality management system.

Full dimensional inspection via CMM and optical measurement equipment.

Material certifications and dimensional inspection reports supplied with every shipment.

Strict zero-defect outgoing quality standard enforced across all production batches.

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.
