Precision CNC machining for prototypes through production combining multi-axis milling and CNC turning. Equipment supports 4th-axis milling, bar-fed and sub-spindle turning, rigid tapping and shop-specific CAM/post-processing for machine-ready NC code. Materials machined include common aluminums, steels, stainless, copper alloys and engineering plastics with process control for repeatable, short- and long-run deliveries.

CNC Machining is subtractive manufacturing performed on computer-numerically controlled machine tools. Toolpaths generated from CAM drive multi-axis milling, turning, and mill-turn equipment to remove material accurately and repeatably. The approach enables tight tolerances, stable process capability, and scalable automation for prototypes through production across metals and engineering plastics.

CNC Machining

CNC Milling removes material with rotating cutters under precise multi-axis computer control, producing complex prismatic or sculpted parts with positional accuracy to ±0.005 mm and surface finishes ≤ Ra 0.4 µm. Machines span 3-axis vertical mills, 4-axis horizontals with pallet changers, and full 5-axis trunnion or gantry platforms, supporting everything from rapid prototypes to lights-out production in metals, plastics, and composites.

CNC Milling

CNC Turning uses computer-controlled lathes to rotate bar, billet, or cast blanks while single-point cutting tools remove material. The process excels at producing concentric OD/ID features, tapers, threads, grooves, and complex contours with tight positional accuracy. Modern CNC lathes support live tooling, Y-axis interpolation, sub-spindle part transfer, and bar-feed automation—enabling complete, high-volume production of precision cylindrical components in metals or plastics.

CNC Turning

Creation of collision-free tool-paths, fixturing strategies and machine-specific post-processed NC code for 3- to 5-axis machining centres, turning, mill-turn and probing cycles, ready for shop-floor execution.

In-house inspection and quality control supporting ISO 9001 traceability and documented acceptance. Metrology resources include calibrated manual gages, comparator/optical inspection, digital height gages and hardness tester for incoming, in-process and final verification. Controls support first-article review, dimensional checks and lot traceability to ensure parts meet drawing requirements prior to shipment.

Inspection & Quality Control (IQC) comprises the metrology, verification, and documentation activities that ensure parts conform to drawing/CAD requirements, customer specifications, and regulatory standards. IQC spans incoming, in-process, and final inspection and leverages coordinate metrology (CMMs and portable arms), laser/structured-light scanning, optical comparators and vision systems, surface-form metrology (profilometers, roundness/contour testers), nondestructive testing (NDT), and statistical process control (SPC). Results are captured in traceable reports (e.g., AS9102 FAIR, PPAP) tied to calibrated gauges and controlled environmental conditions.

Inspection & Quality Control

Dimensional Inspection verifies that a part’s physical dimensions match design tolerances. Tools include calipers, micrometers, and CMMs, ensuring geometric accuracy of length, width, height, angles, and more.

Dimensional Inspection

Measurement encompasses various techniques and instruments for quantifying dimensions, angles, tolerances, or other parameters to ensure parts meet required specifications.

Measurement

Establishes and maintains a metrology program that calibrates dimensional gauges, torque wrenches, force and pressure transducers, and electronic inspection devices traceable to NIST or equivalent standards. Includes periodic gauge repeatability & reproducibility (Gage R&R) studies to verify measurement system capability and ensure Cp/Cpk compliance for AS9100, ISO 9001, and IATF 16949 quality systems.

In-line and post-process value-added services to deliver production-ready parts. Shop capabilities include vibratory deburring and finishing, parts washing/cleaning, and preparation for coating or assembly. These tasks are integrated into production workflows to reduce touch-points, speed lead times and supply cleaned, deburred parts ready for subsequent finishing or assembly.

Secondary operations & value-added services encompass in-line or post-process tasks—deburring, tapping, assembly, labeling, special cleaning or final customization—that manufacturers perform in-house but typically do not sell as stand-alone services. This catch-all pillar groups low-visibility steps so buyers understand a supplier’s complete in-house capabilities without cluttering the primary taxonomy.

Secondary Operations & Value-Added Services

Deburring is a critical post-processing operation that removes sharp edges and burrs from metal parts resulting from machining operations. It is essential for ensuring part functionality, safety during handling, and preparing surfaces for further finishing processes. Deburring can be performed using manual techniques, mechanical methods, or through thermal energy, and is applicable across a wide range of industries where smoothness of the part surface is required.

Deburring

Ultrasonic Cleaning uses ultrasound and a cleaning solvent to remove contaminants from delicate or complex parts. Common in healthcare, electronics, and automotive where high cleanliness standards are vital.

Mechanical assembly and light integration services to deliver sub-assemblies or install hardware prior to shipment. Capabilities include PEM/insert installation, torque-verified fastening, hardware insertion and simple kitting. In-house assembly reduces supplier hand-offs and enables delivery of installed/torqued components or bag-and-tag lot-controlled kits.

Assembly & Integration Services encompasses mechanical fastening, ultrasonic welding, heat staking, electronics and hardware integration, sub-assembly kitting, and packaging services to deliver complete assemblies or kits ready for immediate installation or shipment.

Assembly & Integration Services

Mechanical Assembly delivers torque-verified installation of fasteners, snap-fits, and press-fits to build robust sub-assemblies.

Mechanical Assembly

Installs brass or stainless self-clinching, heat-set, or ultrasonic threaded inserts into plastic components using temperature-controlled soldering tips or induction heads. Precise thermal profiles ensure full material re-flow around the knurl, achieving pull-out strengths comparable to over-molding without distorting surrounding features.
