Press Release Body
Dongguan Changxinda Precision Technology Co., Ltd., a leading CNC machining expert and CNC machining manufacturer based in Dongguan China, today announced the formal integration of HEXAGON bridge-type Coordinate Measuring Machine (CMM) inspection into its standard sample-to-mass-production workflow for custom CNC machined precision components. This upgrade reflects Changxinda's ongoing commitment to delivering sample-confirmed precision quality for engineering procurement and international trade customers across aerospace, optical equipment, automation systems, medical devices, and high-end industrial applications. As an experienced CNC machining supplier and CNC machining factory, the company has processed thousands of sample orders and mass production batches, and the new HEXAGON CMM integration ensures that every sample part is fully measured and reported to the customer before any mass production release.
The Changxinda sample-to-mass-production workflow operates as a structured six-stage process: customer drawing and requirement intake, engineering drawing review and DFM analysis, sample CNC precision machining, HEXAGON CMM full-dimensional sample inspection with formal inspection report, customer sample confirmation, and then mass production release. Each stage is controlled with strict quality gates to ensure that the customer's design intent is fully realized before the customer invests in batch production. This systematic workflow has proven especially valuable for engineering procurement and international trade customers who require formal dimensional verification documentation before authorizing production orders.
Stage one covers customer drawing and requirement intake. Customers submit 2D drawings, 3D CAD files (STEP, IGES, SolidWorks, CATIA, Pro-E, UG, Mastercam), MBD models with PMI, or physical samples along with their application requirements, material preferences, surface treatment specifications, and delivery timelines. The Changxinda engineering team reviews every submission within 24 hours and confirms receipt of all required documentation. This intake stage ensures that the project scope is fully understood before any engineering work begins.
Stage two covers engineering drawing review and DFM analysis. The Changxinda engineering team performs detailed review of customer drawings for dimensional specifications, GD&T (Geometric Dimensioning and Tolerancing) callouts, material specifications, and surface treatment requirements. DFM (Design for Manufacturing) analysis identifies any manufacturing concerns and recommends design optimizations for improved manufacturability, reduced cost, and enhanced quality. The engineering team provides feedback on manufacturability, material selection, and tolerance feasibility before sample machining begins.
Stage three covers sample CNC precision machining. Based on the reviewed and optimized design, Changxinda's CNC machining centers produce the sample parts using the specified materials and surface treatments. The company operates advanced 5-axis CNC machining centers, turn-mill composite machines, and CNC precision milling centers capable of producing complex precision components in materials including aluminum alloys (6061, 6063, 7075, 2A12), stainless steel (304, 316, 17-4 PH, 15-5 PH), titanium alloy (TC4, TC11), brass (H59, H62, H65), engineering plastics (PC, PMMA/acrylic, POM, Delrin), and specialty alloys. Sample machining typically completes within 1-2 weeks depending on complexity.
Stage four covers HEXAGON CMM full-dimensional sample inspection. This is the critical quality gate that distinguishes Changxinda from basic CNC machining workshops. Every sample part undergoes comprehensive HEXAGON CMM 3-axis measurement with formal inspection report generation. The HEXAGON bridge-type CMM is mounted on a precision granite surface plate and equipped with precision touch probes that perform point-by-point 3D measurement of all critical dimensions, GD&T features, and geometric tolerances. The inspection report includes measured values, nominal values, tolerances, deviations, pass/fail status, and visual mapping of deviation distribution. Inspection categories include dimensional measurements (length, width, height, diameter, depth), geometric measurements (flatness, straightness, roundness, cylindricity), orientation measurements (perpendicularity, parallelism, angularity), location measurements (position, concentricity, symmetry), and runout measurements (circular runout, total runout). The HEXAGON CMM provides micron-level measurement accuracy essential for high-precision verification.
Stage five covers customer sample confirmation. The completed sample parts are packaged together with the formal HEXAGON CMM inspection report and shipped to the customer for confirmation. The customer reviews the sample physical quality, dimensional compliance, surface finish, and functional fit-up against their original design requirements. The customer provides formal sample approval or requests modifications if needed. Changxinda supports customer sample reviews via email, video call, on-site factory visit, or third-party inspection agency engagement based on customer preference.
Stage six covers mass production release. Upon customer sample confirmation, the CNC machining project enters the formal mass production stage. Changxinda applies the validated CNC programs, tooling selections, cutting parameters, and inspection checkpoints to the production batch. During mass production, the quality control team performs in-process inspection at critical stages and final pre-shipment inspection on every production part. The HEXAGON CMM is used for periodic batch sampling inspection to verify dimensional consistency throughout the production run. The HEXAGON CMM full-dimensional inspection capability is one of the key factors that enables Changxinda to maintain stable dimensional quality across production batches of complex precision components.
The HEXAGON CMM inspection service is particularly valuable for transparent material parts, where visual inspection is insufficient for dimensional verification. Transparent PC, acrylic (PMMA), and polycarbonate components require CMM-based measurement because the transparent material makes optical measurement methods unreliable. The HEXAGON CMM touch probe measurement works equally well on transparent materials and metals, providing accurate dimensional data regardless of material transparency. This capability is especially valuable for optical equipment housings, lens components, transparent medical device parts, and clear instrumentation enclosures where dimensional verification is critical but visual inspection is limited.
The HEXAGON CMM inspection also enables Changxinda to provide formal inspection reports that engineering procurement and international trade customers require for their own quality management systems. The formal HEXAGON CMM inspection report documents every critical dimension, GD&T feature, and pass/fail status with traceable measurement data. This documentation supports customer ISO 9001, AS9100, IATF 16949, and other quality management system requirements. The formal inspection report is provided in standard formats including PDF, Excel, and customer-specified formats based on requirements.
