Detailed description

Custom CNC Turned Slotted Brass Collet Chuck Sleeve

Our Custom CNC Turned Slotted Brass Collet Chuck Sleeve is a precision stepped cylindrical component with longitudinal elastic slots for clamping positioning. As a professional CNC turning manufacturer based in Dongguan, we produce customized brass collets with ±0.01mm high precision tolerance for global automation fixture and testing equipment suppliers. We support drawing-based OEM & ODM manufacturing, with flexible customization of inner bore, outer diameter, overall length, step dimensions and slot layout. These brass collet sleeves deliver reliable elastic clamping force, widely adopted for positioning, clamping and fixing workpieces in test jigs, electrical connectors and precision assembly equipment.

Introduction to CNC Lathe Turning Technology

CNC lathe turning is one of the most precise and efficient manufacturing methods for rotational metal components used in industrial automation and precision equipment. Using programmable multi-axis turning centers, metal bars are processed through continuous cutting, facing, grooving, threading and boring with computer-controlled accuracy.
Compared with manual machining and conventional milling, precision CNC turning achieves stable dimensional tolerance down to ±0.01mm, smooth surface quality and outstanding consistency during mass production. It is widely applied to fabricate pins, shafts, bushings, connectors and threaded parts for mold, electronics, medical, automotive and automation machinery.
Equipped with secondary milling and cutting capacity, CNC turning supports complex customized profiles including stepped cylinders, grooved structures and slotted features, satisfying diversified precision positioning component demands for industrial equipment.

What Is Slotted Brass Collet Chuck Sleeve & Its Industrial Function

A slotted brass collet chuck sleeve, also known as split brass clamping mandrel, is an elastic fixture part with multiple axial slots. When receiving external compression, the collet shrinks evenly to clamp inner or outer workpieces tightly and achieve accurate positioning.
Brass material brings good ductility, excellent elasticity and wear resistance, making it ideal for repeated clamping applications. Concentricity, slot uniformity and surface roundness directly affect clamping stability. Poor processing precision will cause uneven clamping force, workpiece deflection and positioning deviation. Therefore, custom CNC turned slotted brass collets are essential elastic clamping components for high-precision automation fixtures and testing equipment.

Custom CNC Turned Slotted Brass Collet Chuck Sleeve

We provide one-stop custom CNC turning solutions for slotted brass collet chuck sleeves, serving precision fixture manufacturers, automation equipment enterprises and electronic component suppliers worldwide.
Our product portfolio covers various elastic clamping parts: stepped slotted brass collets, single/multi-split clamping sleeves, thin-wall brass collets, positioning mandrels and non-standard customized collet components.
All parts are machined on multi-axis CNC lathes, including turning contour, internal boring, slot cutting, chamfering and precision deburring. All machining procedures are implemented strictly according to your 2D/3D engineering drawings. Besides individual collet products, we can also supply matching accessory parts to simplify your procurement and assembly work.

Key Advantages of Our CNC Turned Slotted Brass Collet Chuck Sleeve

Stable concentricity & uniform elastic clamping

Manufactured on multi-axis CNC turning equipment, the inner hole maintains excellent concentricity. The evenly processed slots ensure consistent shrinkage force during clamping for accurate workpiece positioning.

Customizable slotted structure and stepped profile

In addition to turning and boring processes, we support slot cutting, chamfering and secondary machining. The slot quantity, depth and stepped dimensions can be adjusted fully to match your fixture assembly requirements.

Brass material with superior elasticity and wear resistance

Adopt high-quality brass stock featuring good ductility, reliable repeated clamping performance. Multiple surface treatment options enhance wear resistance and anti-oxidation performance for long-term continuous operation.

Fully customizable dimensional parameters

Inner bore size, outer diameter, total length, shoulder height and slot distribution can be modified freely per your drawings or samples. Non-standard new structural designs are acceptable for new product development.

Complete capacity from prototype to mass production

We support small-batch prototype trial production and large-volume bulk orders. Unified quality standards are implemented in every batch to meet long-term procurement demands of global industrial clients.

Frequently Asked Questions

FAQ 1

Q: Can you produce custom CNC turned parts according to my drawings or samples?
A: Yes, we mainly focus on OEM & ODM customized precision turning services. We accept 2D files like PDF/DWG and 3D files such as STEP, IGES. You can also send physical samples for us to reverse-engineer and optimize the structure. Our engineering team will review your design and offer professional suggestions on cost saving and manufacturability (DFM) for free.

FAQ 2

Q: What kinds of metal materials can you use for CNC turning processing?
A: We support a full range of common precision machining metals, including SUS304/SUS316 stainless steel, 1018/1045 carbon steel, 6061/7075 aluminum alloy, C36000 brass, copper and titanium. We can select suitable raw materials based on your product usage, working environment, strength requirements and budget.

FAQ 3

Q: Can I get trial samples before mass production? How long is the sample lead time?
A: Trial samples are available for all customized turning orders. The sample production cycle is 3–7 working days after drawing confirmation. After you test and confirm the sample quality and dimensions, we will arrange mass production. Small batch trial orders are also acceptable if you do not need large volume at first.

FAQ 4

Q: What surface finishing options do you provide for CNC turned metal parts?
A: We offer multiple surface treatments to meet anti-rust, anti-corrosion, wear resistance and appearance demands: passivation, electropolishing, zinc plating, nickel plating, black oxide, powder coating, anodizing for aluminum, sandblasting and polishing. If your products are exported to Europe, we can provide surface treatment that complies with RoHS and REACH standards.

FAQ 5

Q: How do you control the dimensional tolerance of precision CNC turned parts?
A: Our standard tolerance for general turned parts is ±0.01mm, and ultra-precision components can achieve ±0.005mm with grinding processes. We carry out strict three-step quality inspection: IQC for raw material incoming check, IPQC for in-process production monitoring, and FQC full dimension testing before shipment. We provide inspection reports and accept third-party quality inspection as requested.
