Detailed description

Custom CNC Turned Conical Tapered Hollow Nozzle Bushing

Our Custom CNC Turned Conical Tapered Hollow Nozzle Bushing is a precision industrial fitting featuring smooth conical taper section, stable cylindrical mounting base and concentric hollow inner bore, designed for fluid convergence, automatic guiding alignment and precise locating assembly. As a professional CNC turning manufacturer based in Dongguan, we produce customized tapered hollow nozzle bushings with ±0.01mm ultra-precise tolerance strictly following customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for total length, base diameter, taper angle, inner bore size and wall thickness. These conical hollow bushings are widely used for fluid spraying, mold guiding, fixture locating, pneumatic exhausting and precision equipment fitting in manufacturing, automation and fluid equipment industries.

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 multi‑sided profiles, satisfying diversified precision positioning component demands for industrial equipment.

Product Definition & Industrial Value

Conical tapered hollow nozzle bushing is a multi-functional precision fitting composed of gradually reduced conical head, cylindrical mounting base and concentric hollow through bore. The tapered conical section realizes automatic centering and guiding during assembly, and forms stable flow convergence for fluid or gas media; the cylindrical base provides accurate positioning and stable installation reference; the hollow inner bore ensures unobstructed medium circulation with controllable flow rate. It solves common industry pain points such as difficult alignment during butt assembly, uneven fluid spraying and poor installation positioning accuracy. The integrally machined structure ensures stable taper precision and reliable concentricity, effectively improving assembly efficiency and working stability for fluid systems and positioning mechanisms.

Our Product Service

We provide one-stop custom CNC turning service for conical tapered hollow nozzle bushings for global fluid equipment, mold and automation equipment suppliers. Our product scope covers various conical nozzles, guide taper bushings, locating cone fittings and other non-standard precision turned components. We complete full precision turning, conical profile finishing, inner bore fine machining, end face chamfering and deburring strictly based on customer engineering drawings. Value-added services include diversified surface treatment, full-dimension inspection, prototype sampling and large-batch OEM production.

5 Core Advantages

Precision conical taper with stable guiding convergence effect

The conical taper section is machined with high precision, featuring accurate taper angle and smooth continuous surface. It realizes automatic centering and guiding during assembly, reduces insertion resistance, and forms stable flow convergence for fluid and gas media, effectively improving assembly alignment accuracy and fluid transmission stability.

Integral hollow structure with uniform wall thickness

The whole fitting is machined from solid bar stock in one clamping, with no welding or splicing seams. The wall thickness is strictly controlled to be uniform, and the inner bore is smooth and concentric with the outer contour, ensuring unobstructed medium flow, high structural strength and good pressure resistance, suitable for long-term stable operation under pressure.

High-quality stainless steel material with excellent corrosion resistance

Standardly made of high-grade SUS304/SUS316 stainless steel, it has excellent corrosion resistance, temperature resistance and fluid compatibility, suitable for water, gas, oil and most conventional industrial media. Optional materials such as carbon steel and brass are also available to match different application scenarios and cost requirements.

High coaxiality for accurate installation and operation

The conical section and cylindrical base are machined with strict coaxiality control, and the end face of the base has high perpendicularity to the axis. It ensures accurate installation positioning, stable operation without eccentricity, and good interchangeability, fully meeting the precision requirements of mold guiding, fixture positioning and precision equipment assembly.

Full-parameter drawing-based customization

All key parameters including total length, base diameter, taper angle, inner bore size and wall thickness can be fully adjusted according to your 2D/3D drawings or physical samples. We accept both small-batch prototype verification orders for new product development and large-volume mass production orders for formal projects.

OEM Custom Service Range

We provide comprehensive customized solutions for custom conical tapered hollow nozzle bushings and all kinds of precision CNC turned components. Available materials include SUS304/SUS316 stainless steel, carbon steel, C36000 brass and 6061‑T6 aluminum alloy, with sufficient bar stock to match different corrosion resistance, pressure resistance and cost requirements.
Our custom product range includes nozzle fittings, guide bushings, locating pins, connecting shafts and other rotational precision machined parts. Selectable surface treatments: natural machined finish, passivation, polishing, zinc plating, nickel plating, black oxide and anodizing.
We can supply single parts or matched hardware kits according to assembly needs. Custom machining will be developed based on your drawings or samples. Small batch prototype testing is available before formal mass production.

Typical Application Scenarios

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.
