CAPABILITIES
Laser Welded Assemblies
Our Nd:YAG pulsed laser welding equipment specializes in achieving seam widths as small as 0.008” (0.2mm), making it ideal for micro-welding of stainless steel wires, hypodermic tubes, CNC machined parts, and other components. We offer rotary micro laser welding for shafts and casings, surgical instrument assemblies, and pull-ring assemblies. Press HERE to submit your enquiry for custom made laser welded assemblies.
Hypodermic Tube
We offer hypodermic tubes crafted from stainless steel, nitinol, titanium, and other exotic metals. Our standard sizes range from 0.008” (0.2mm) diameter to ¼” (6.35mm) diameter. If you need custom CNC machined parts, click HERE to submit your enquiry for a custom-made tube. Specializing in thin wall tubes, we deliver products with wall thicknesses as low as 0.003” (0.075mm). Additionally, we provide laser welded assemblies to meet your precise requirements.
Sliding Head CNC Machined Parts
Medical Titanium Tube, Wire & Profiles
Paarl Precision utilizes sliding head machining, also known as Swiss-type machining or sliding headstock machining, as a highly precise and efficient manufacturing process for producing small, complex parts, such as CNC machined parts, with tight tolerances. This technique is widely used across sectors like aerospace, medical, automotive, and electronics for components including hypodermic tubes, screws, pins, connectors, and laser welded assemblies.

Precision Manufacturing Capabilities Specialist Laser, Machining and Assembly Solutions
Surface-finish requirements for CNC machined parts are considered alongside dimensional tolerances and the functional purpose of the component, such as hypodermic tubes or laser welded assemblies.
Depending on the material, geometry, and machining operation, a typical turned surface finish of approximately Ra 0.8 µm may be achieved. Finer finishes approaching Ra 0.4 µm may be possible on selected features following an engineering review.
The achievable finish can be influenced by:
- Material grade.
- Component rigidity.
- Tool access.
- Feature size and geometry.
- Machining direction.
- Required production quantity.
- Subsequent cleaning, welding, or assembly processes.
Any critical surface-finish requirements should be stated clearly on the customer drawing.
Manufacturing Capability Summary
Our miniature CNC machining capability includes production of high-precision CNC machined parts, specifically designed for manufacturing hypodermic tubes and other small, complex components. Our equipment features Rofin Baasel Select laser welders and Fibre Tube Laser Cutters available in femtosecond and non-femto options ranging from 100w to 1kw. We utilize Citizen and Star Micronics Swiss-type sliding-head CNC lathes to ensure general machining tolerances of ±0.01 mm, with critical dimensions achievable to ±0.005 mm and selected features approaching ±0.0025 mm, subject to engineering review. We specialize in prototype, low-volume, and repeat production runs while offering complementary laser welded assemblies, tube processing, and precision assembly services. Our Keyence vision measurement and inspection systems support our ISO 9001:2015-certified quality management processes. Please send us your drawing, material specification, required quantity, and critical tolerances. Our engineering team will review the component and confirm the appropriate manufacturing and inspection route.
