Technical Capabilities
Honyo Prototype – Secondary Machining Capabilities
Honyo Prototype specializes in high-precision secondary machining for prototypes and low-volume production runs. Our in-house CNC machining center supports complex geometries and tight-tolerance components across a range of engineering-grade materials. We support 3-axis, 4-axis, and 5-axis milling, as well as precision turning operations, ensuring high repeatability and surface finish consistency.

We routinely machine components requiring tight geometric tolerances (GD&T), including true position, flatness, and runout control. Materials such as aluminum and steel are machined with coolant for thermal stability, while plastics like ABS and nylon are processed using optimized speeds and feeds to prevent deformation. Our 5-axis simultaneous machining capability enables complex organic shapes and deep cavity features with minimal setup, reducing lead time and improving accuracy.
From CAD to Part: The Process
Honyo Prototype Secondary Machining Workflow for Partner Companies
Honyo Prototype delivers precision secondary machining services tailored for partner manufacturing firms requiring post-primary process operations such as tight-tolerance milling, turning, grinding, or complex feature integration. Our streamlined workflow ensures technical rigor, cost transparency, and accelerated time-to-part without compromising quality. Below is the end-to-end process:
Upload CAD
Partners initiate the process by uploading native CAD files (STEP, IGES, or native formats like SOLIDWORKS or NX) via our secure customer portal. We require complete geometric data, including critical dimensions, datums, and surface finish specifications per ASME Y14.5 standards. Non-disclosure agreements are automatically applied upon upload to protect intellectual property.
AI-Powered Quoting Engine
Uploaded CAD data undergoes automated analysis through our proprietary AI quoting system. This engine cross-references 10+ million historical machining datasets to evaluate geometry complexity, material machinability (e.g., 7075-T6 aluminum vs. Inconel 718), tooling requirements, and fixture strategies. The output is a detailed quote within 2 business hours, including:
Breakdown of machining hours by operation (milling, turning, etc.)
Material waste calculations based on stock size optimization
Real-time pricing aligned with current commodity rates
Lead time estimates factoring in machine availability and priority scheduling
Engineering-Driven DFM Analysis
Quotes trigger a mandatory Design for Manufacturability review by our senior manufacturing engineering team. Unlike automated-only checks, this phase combines AI insights with human expertise to identify:
Geometric clashes in 5-axis toolpaths
Non-optimal wall thicknesses risking chatter or deflection
Unnecessarily tight tolerances inflating costs (e.g., suggesting ±0.005″ instead of ±0.001″ where functional)
Suboptimal stock allowances for subsequent grinding operations
We provide a collaborative DFM report with annotated CAD markups and actionable recommendations, requiring partner approval before proceeding.
Precision Production Execution
Approved designs move to dedicated CNC cells equipped with industry-leading Haas, DMG MORI, and Makino machines. Key production protocols include:
First-article inspection using calibrated CMMs with full GD&T validation against CAD
In-process SPC monitoring of critical dimensions (Cpk ≥1.33 maintained)
Real-time tool wear compensation via IoT-enabled machine sensors
Dedicated material traceability logs from bar stock to final part
All secondary operations adhere to ISO 9001:2015 and AS9100D standards, with non-conformance protocols triggering immediate engineering escalation.
Certified Delivery & Documentation
Completed parts undergo final inspection per the agreed quality plan, generating comprehensive documentation:
Dimensional reports with actual vs. nominal values
Material certification (mill test reports)
Process capability data for critical features
Cleanliness verification for aerospace/medical applications
Parts ship via tracked logistics with real-time ETA updates. Standard lead time from CAD upload to delivery is 7–12 business days for 1–50 part quantities, adjustable for urgent requirements through our expedited tier.
This integrated workflow eliminates traditional quoting ambiguities and DFM rework cycles, reducing time-to-part by 35% compared to conventional secondary machining vendors while ensuring first-pass yield rates exceed 98.5%. Partners maintain full visibility via our customer portal, which provides live production dashboards and revision-controlled documentation access.
