Technical Capabilities

CNC Brass Parts – Technical Specifications Overview

Honyo Prototype delivers high-precision CNC machined brass components utilizing advanced 3-axis, 4-axis, and 5-axis milling technologies, as well as multi-axis turning centers. Our processes are optimized for tight tolerance requirements, surface finish consistency, and complex geometries. While brass is our primary focus, we also support precision machining of aluminum, steel, ABS, and nylon materials for integrated or comparative applications.

The following table outlines key technical specifications for CNC brass parts, with comparative data across compatible materials:

All brass components are machined from certified C36000 (free-cutting brass) stock, ensuring optimal machinability and dimensional stability. Our 5-axis milling centers enable single-setup production of complex 3D contours, reducing cumulative tolerance stack-up and improving repeatability. Tight tolerance runs are verified using CMM (Coordinate Measuring Machine), optical comparators, and laser micrometers to ensure compliance with ISO 2768-f or customer-specific GD&T standards.

For mission-critical applications in aerospace, medical, and automation industries, we offer full first-article inspection (FAI) reporting and PPAP documentation upon request.

From CAD to Part: The Process

Honyo Prototype CNC Brass Parts Production Workflow

Honyo Prototype employs a rigorously optimized process for CNC brass parts manufacturing, designed to ensure precision, cost efficiency, and rapid turnaround. The workflow begins with secure CAD file submission via our encrypted client portal, accepting industry-standard formats including STEP, IGES, and native SOLIDWORKS files. This initial step validates geometry integrity and material specifications, with immediate automated feedback on file compatibility to prevent downstream delays.

AI-Powered Quoting with Material Intelligence
Upon CAD validation, our proprietary AI quoting engine analyzes part geometry, tolerances, and brass alloy requirements to generate an instant preliminary quote. The system cross-references real-time brass market pricing (e.g., C36000, C26000), machine utilization rates, and historical production data for brass-specific machining parameters. Crucially, this phase includes AI-driven material substitution suggestions—such as recommending free-machining C36000 for complex geometries to reduce cycle times by 15–20% versus standard C26000—while flagging potential cost drivers like thin-wall sections prone to chatter in brass. Human engineers review all AI outputs within 2 business hours to validate feasibility.

Brass-Specific DFM Analysis
The Design for Manufacturability (DFM) phase is where Honyo’s brass expertise is critical. Our engineers conduct a material-focused review addressing brass’s unique properties:

Parameter	Brass-Specific Consideration	Honyo Mitigation Strategy
Chip Formation	Long, stringy chips in non-lead brass alloys (e.g., C26000) risk tool damage	Recommend C36000 or adjust feed rates/spindle speeds; implement high-pressure coolant
Wall Thickness	Minimum 0.5mm walls prone to vibration-induced deformation	Suggest localized ribbing or alternative alloy (C37700) for rigidity
Surface Finish	Tarnishing risk during extended machining	Specify passivation post-machining; optimize toolpath stepovers
Tolerances	Thermal expansion (19.3 µm/m°C) affecting tight tolerances	Apply thermal compensation algorithms in CAM programming

This phase includes actionable feedback on draft angles for brass’s low friction coefficient, avoidance of sharp internal corners to prevent micro-cracking, and plating compatibility assessments. Clients receive a detailed DFM report with revision suggestions, typically within 24 hours.

Precision Brass Production
Production leverages Honyo’s dedicated brass machining cells equipped with hardened spindles and corrosion-resistant coolant systems to handle brass’s lead content (in alloys like C36000). Key protocols include:
Machine-specific parameter sets: 500–800 SFM surface speeds, 0.003–0.010 IPR feeds tailored to brass alloy hardness
In-process metrology using coordinate measuring machines (CMMs) for critical features, with real-time SPC tracking of brass’s dimensional stability
Secondary operations (e.g., threading, knurling) performed in the same setup to minimize handling-induced deformation
Strict scrap segregation for brass recycling compliance, reducing material waste by 22% versus industry averages

All brass parts undergo final cleaning in non-ionic solutions to prevent oxidation before packaging in anti-tarnish VCI paper.

Traceable Delivery
Completed parts ship with full documentation: first-article inspection reports (FAIRs), material certificates (including RoHS/REACH compliance), and batch-specific process logs. Honyo’s logistics system provides GPS-tracked shipping with delivery confirmation, typically achieving 7–10 day lead times for prototypes and 12–15 days for low-volume production runs. Critical brass components (e.g., hydraulic fittings, electrical contacts) include serialized traceability from raw material lot to finished part, ensuring full auditability for regulated industries. This integrated workflow eliminates typical brass machining pitfalls while maintaining cost transparency from CAD upload to doorstep delivery.
