Surface Finish	As-machined: Ra 3.2 µm; Optional finishes: Ra 1.6 µm, Ra 0.8 µm, and polishing available
Maximum Work Envelope	Milling: 1000 mm × 600 mm × 500 mm (X-Y-Z); Turning: Ø300 mm × 500 mm length
Spindle Speed (Milling)	Up to 24,000 RPM for high-precision finishing
Positioning Accuracy	±0.002 mm per axis
Repeatability	±0.003 mm
Primary Materials	Stainless Steel (303, 304, 316, 17-4 PH), Aluminum (6061, 7075, 2024), Carbon Steel (1018, 4140), Plastics (ABS, Nylon 6, Nylon 6/6)
Material Suitability	Stainless Steel: Ideal for corrosion-resistant, high-strength parts; Aluminum: Lightweight, high machinability; ABS: Prototyping, low stress; Nylon: Wear resistance, low friction

From CAD to Part: The Process

Honyo Prototype delivers precision stainless steel CNC machining services through a rigorously defined five-stage workflow designed for technical accuracy, cost transparency, and on-time delivery. This process is optimized specifically for stainless steel alloys including 303, 304/L, 316/L, 17-4 PH, and other demanding grades requiring controlled machining parameters and post-processing.

Upload CAD
Clients initiate the process by uploading native CAD files (STEP, IGES, Parasolid, or native SOLIDWORKS) via our secure customer portal. We require complete geometric data including critical dimensions, datums, and material specifications. For stainless steel components, explicit identification of alloy grade and finish requirements (e.g., #4 brushed, 2B mill, or electropolished) is essential at this stage to ensure downstream process alignment. Unsupported formats trigger immediate client notification for resubmission.

AI Quote Generation
Our proprietary AI engine analyzes the CAD geometry against real-time stainless steel machining parameters, material costs, and machine availability. The algorithm factors in stainless-specific variables: work hardening tendencies requiring optimized feed rates, coolant requirements for thermal management, tool wear compensation for abrasive alloys, and secondary operation needs like passivation or deburring. Clients receive a detailed quote within 2 business hours, including DFM-noted recommendations, firm pricing, and lead time validated against current shop floor capacity. No manual intervention occurs at this stage, eliminating estimation variance.

DFM Analysis
Before production, our engineering team conducts a mandatory Design for Manufacturability review focused on stainless steel challenges. This phase identifies geometric features prone to deflection during machining, evaluates tolerance stack-ups against stainless steel’s thermal expansion properties, and verifies surface finish feasibility. Critical DFM checks include:

Parameter	Standard Practice	Stainless Steel Specific Action
Wall Thickness	Minimum 0.5mm	Enforce ≥1.0mm to prevent chatter in 304/316
Internal Radii	Match standard tooling	Specify ≥0.8mm radius; avoid sharp corners
Deep Cavities	Step-down depth analysis	Limit depth-to-diameter ratio to 3:1
Tight Tolerances	GD&T validation	Flag tolerances <±0.025mm requiring slow-speed finishing
Surface Finish	Roughness requirement assessment	Mandate stress-relieving before fine finishes

Clients receive a formal DFM report with actionable revisions. Approval is required before proceeding to production.

Production Execution
Machining occurs on dedicated stainless steel-optimized CNC equipment (Haas, DMG MORI, Okuma) with rigid setups and carbide tooling specifically graded for stainless alloys. Key production protocols include:
Pre-machining stress relief annealing for complex geometries
Minimum 8% concentration soluble oil coolant to prevent galling
In-process CMM verification at critical feature completion points
Dedicated fixturing to avoid cross-contamination from carbon steel jobs
Sequential operations: roughing → semi-finishing → finishing with tool wear monitoring
All components undergo post-machining passivation per ASTM A967 (Method 5 for 300-series) and decontamination prior to final inspection.

Delivery Assurance
Completed parts undergo tripartite validation: first-article inspection (FAI) per AS9102, batch-level dimensional verification, and material certificate traceability. Stainless steel components include Mill Test Reports (MTRs) confirming chemistry and mechanical properties. Parts ship in anti-tarnish VCI packaging with humidity indicators, accompanied by full inspection documentation (including surface roughness reports for critical faces). Logistics utilize tracked freight with climate-controlled options for sensitive applications, with delivery confirmation including digital POD and real-time shipment tracking.

This closed-loop process ensures stainless steel components meet stringent aerospace, medical, and semiconductor industry requirements while maintaining Honyo’s 99.2% on-time delivery rate. All stages comply with ISO 9001:2015 and IATF 16949 quality management systems.
