Our step brass hollow sleeve is a fully custom CNC turning machined component fabricated from seamless brass tube raw stock. The base raw material is 6mm outer diameter brass tubing with a 4mm through inner bore, processed on high-precision CNC turning equipment to turn one segment down to a 5.5mm outer diameter stepped section.
After mechanical CNC turning processing, every brass component undergoes full degreasing ultrasonic washing to eliminate machining oil residues, then chemical passivation treatment to boost brass corrosion resistance and preserve its metallic luster long-term.
As a dedicated CNC machining manufacturer, we deliver full OEM custom service for this brass sleeve and all similar tubular brass fittings. We welcome clients to submit custom engineering drawings or physical samples for bespoke dimension, tolerance, surface finish modification to match unique industrial equipment assembly requirements.
Tolerance Customization: Tighten dimensional tolerance standards for high-precision industrial CNC turning parts
Batch Customization: Support low-volume trial orders and large-scale mass production
Packaging Customization: Custom export safe packaging for overseas wholesale clients
Product Advantages
Advanced CNC turning processing with ±0.01mm tight tolerance, uniform dimensions in every production batch, no assembly mismatch issues
Standard passivation post-processing delivers long-lasting anti-corrosion performance, avoids surface discoloration during equipment storage & operation
We source qualified seamless brass tube raw stock in bulk, no material supply shortage delays for your CNC turning part orders
Our engineering team reviews customer drawings/samples fast, offers professional technical feedback to optimize part structure for lower CNC turning production cost
Full automatic ultrasonic degreasing cleaning removes all cutting oil residue, clean inner and outer tube surfaces for smooth assembly
Flexible CNC turning production line supports both small prototype batches and large wholesale mass orders, meets all client order volume demands
Quality Control
Raw Material Inspection: All incoming brass tube blanks pass outer diameter, inner hole and material composition test before entering CNC turning production
Post Surface Treatment Inspection: Full visual inspection after degreasing & passivation, screen out parts with surface stains, scratches or incomplete passivation coating
Finished Product Full Dimensional Test: Random batch sampling to verify all key dimensions (outer diameter, length, inner bore) meet drawing tolerance requirements for CNC turning components
Batch Quality Record Keeping: Save all inspection reports for every production batch to enable full traceability of all CNC turning brass parts
Pre-shipment Quality Audit: Final overall check before export packaging to guarantee zero defective CNC turning goods delivered to overseas clients
FAQ
Q1: Can I customize the dimensions of this stepped brass sleeve?
A1: Yes, we are an OEM custom CNC turning manufacturer, we can adjust OD, ID, length, step sizes per your drawings or samples via CNC turning processing.
Q2: What is the minimum order quantity for custom brass CNC turning parts?
A2: We support small trial sample orders, no strict MOQ requirement, and we offer competitive unit prices for large mass production batches of CNC turning brass components.
Q3: What surface treatment options do you offer for brass CNC turning components?
A3: Our standard process is degreasing cleaning plus anti-corrosion passivation; we also provide mirror polishing, nickel plating custom surface finishes on request for CNC turning brass parts.
Q4: How long will it take to make custom prototypes based on my drawings?
A4: Normally custom CNC turning prototype samples can be finished within 3-7 working days, mass production lead time depends on your total order quantity.
Q5: What tolerance level can your CNC turning machining achieve?
A5: Our standard dimensional tolerance is ±0.01mm, we can achieve tighter customized tolerance standards for ultra-precision industrial CNC turning applications.
