High-precision CNC machining combining multi-axis milling and turning to deliver complex prismatic and cylindrical components. Machines range from 3-axis to 9-axis interpolation and include mill-turn platforms enabling single-setup, tight-tolerance production for aerospace, medical, and communications parts with in-process probing and lights-out automation for repeatable dimensional accuracy and reduced cycle times.

Automated machining cell / robotics integration

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 Mill-Turn Machining combines multi-axis turning and milling in a single setup. Workpieces are clamped once and processed on opposed spindles with live tooling, Y-axis milling, and simultaneous interpolation up to 9 axes. This eliminates part re-clamping, improves concentricity between turned and milled features, and compresses overall cycle time for complex prismatic-plus-cylindrical components used in aerospace, medical, and high-mix/low-volume production.

CNC Mill-Turn Machining

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

Simultaneous 5-Axis Machining enables continuous, synchronized movement of all five machine axes, drastically reducing setups and facilitating the creation of highly intricate geometries with superior surface finishes.

Simultaneous 5-Axis Machining

Precision CNC Machining

In‑house engineering and Design for Manufacturability (DFM) services that reduce cost and speed time‑to‑production. Engineers perform manufacturability reviews, part/assembly optimization, cost‑driver analysis, and prototyping feedback loops to simplify features, select optimal materials/processes, and minimize tooling and cycle time prior to production release.

Design-for-manufacturability and design-for-assembly consulting evaluates product designs for optimal manufacturability, assembly cost reduction and quality control. Experts deliver actionable reports on feature simplification, material selection, draft angles and assembly gauge strategies to reduce cycle times and scrap rates.

Product Design – Industrial Design

Engineering & Design for Manufacturability (DFM)

Comprehensive inspection, metrology, and quality control to ensure parts meet drawing and regulatory requirements. Capabilities include CMM and portable arm measurement, optical/laser scanning for CAD comparison, surface metrology, SPC, and first‑article/PPAP documentation with traceable calibration and data delivery.

Coordinate measuring machine (CMM) inspection

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

3D Coordinate Measurement uses coordinate measuring machines (CMMs) or other 3D metrology tools to capture precise data points on a part’s surface, essential for verifying complex geometries and alignment.

3D Coordinate Measurement

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

Post‑process finishing and value‑added services performed in‑house to deliver ready‑to-use components. Services include deburring, surface treatments (anodize, plating, electropolish), light assembly, marking/serialization, cleaning, and custom packaging—reducing supply‑chain handoffs and ensuring consistent final quality.

Finished anodized housings and assemblies

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

Surface treatment & finishing encompasses chemical, mechanical and thermal operations—tumbling, vibratory deburr, abrasive blasting, electropolishing, anodizing, chromate conversion, hard-chrome or nickel plating, powder coating, wet painting and ceramic or PVD/CVD overlays—that modify a part’s surface for appearance, corrosion resistance, wear protection or adhesion. Processes routinely achieve ≤ 8 µin Ra finishes, controlled coating thickness from 0.0001 in to 0.010 in and salt-spray performance exceeding 1 000 h to ASTM B117.

Surface Treatment & Finishing

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

Anodizing is an electrochemical process that enhances the natural oxide layer on metal parts, primarily aluminum. It improves corrosion resistance, wear resistance, and surface hardness, and can also be used for color finishing. Anodizing is essential in industries like aerospace, automotive, and consumer electronics. The process includes Type II for decorative finishes and Type III for hard anodizing, providing a thicker, wear-resistant layer.
