Straton Industries fuses simultaneous 5‑axis machining, high‑speed 3‑/4‑axis surfacing, 120‑inch long‑bed turning, and 78‑inch‑swing vertical turning into a lights‑out, palletized cell driven by SPC and in‑process probing. The integrated platform holds ±0.0002‑inch true‑position and 16 µin Ra finishes on aluminum, titanium, Inconel, and hardened steels—from one‑off prototypes through midsize production—accelerating aerospace, defense, and energy programs.

Machining encompasses a variety of manufacturing processes aimed at shaping and removing material from a workpiece. This includes both computer-controlled processes, such as CNC milling, turning, and routing, as well as non-traditional methods like Electrochemical, Chemical, and Photochemical Machining.

CNC Machining

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

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

Boring is a precision machining process focused on enlarging pre-existing holes in a material. This operation is essential in both CNC milling and turning, where it's used to achieve greater accuracy and smooth internal surface finishes. Boring allows for the creation of holes with tight tolerances and is often employed in applications requiring precise hole sizes, such as in engine cylinders and hydraulic systems.

Boring

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

Large-diameter vertical turning (up to 2 m swing) with live-tool milling/drilling for flanges, rotors and bearing journals requiring < 0.01 mm run-out and Ra ≤ 0.8 µm surfaces.

Vertical Turning / VTL Machining

High-Speed 3-D Profiling employs lightweight cutters, small step-overs, and spindle speeds above 15 000 rpm to machine free-form surfaces with minimal hand finishing. Advanced look-ahead controls and trochoidal toolpaths maintain constant chip load, enabling precision sculpting of mould cavities, turbine blades, and biomedical implants with surface finishes as fine as Ra 0.2 µm.

High-Speed 3-D Profiling & Surfacing

Specialised CNC strategies for nickel-, cobalt- and refractory-alloy machining (Inconel®, Hastelloy®, Waspaloy®…) using high-pressure coolant and torque monitoring to maintain ±0.005 mm size repeatability.

Exotic-Alloy CNC Machining

Precision CNC Machining

Straton Industries’ EDM department combines high‑precision wire, sinker, and fast‑hole drilling to generate burr‑free features unattainable by conventional machining. Multi‑axis wire machines cut 30° tapers, 0.004‑in kerfs, and 0.010‑in radii while unattended for up to 100 hours; sinker EDM produces deep, sharp‑cornered cavities; fast‑hole EDM drills start‑holes and cooling circuits through hardened Inconel in minutes. The cell routinely holds ±0.0001‑in geometry and 8–12 µin Ra finishes across aerospace, turbine, medical, and semiconductor alloys.

Electrical Discharge Machining removes material from electrically conductive workpieces by rapidly recurring spark-erosion between an electrode and the workpiece immersed in a dielectric. Because the process is non-contact and generates virtually no cutting force, EDM can machine hardened tool steels, super-alloys, and complex internal cavities that are impractical for conventional machining, with dimensional accuracy to ±0.005 mm and surface finishes down to Ra 0.2 µm.

Electrical Discharge Machining (EDM)

Cuts precise slide lugs, gate inserts, and other through-features in die components using continuous wire spark-erosion for ±0.005 mm accuracy.

Wire EDM

Creates deep core details, ejector slots, and sharp interior corners in die steel by spark-erosion where conventional milling cannot reach.

Sinker EDM

EDM Drilling (also called Fast-Hole or Micro-Hole EDM) uses a rotating tubular electrode with pressurised dielectric to rapidly erode small, high-aspect-ratio holes in any conductive material. Diameters down to 0.2 mm and depths exceeding 100× Ø can be produced without burrs, making the process ideal for turbine blade cooling holes, fuel-injector orifices, starter holes for Wire EDM, and micro-fluidic components—even after heat treatment.

EDM Drilling (Fast-/Micro-Hole)

Straton Industries’ finishing cell blends CNC jig, cylindrical, contour‑surface grinding and precision Sunnen honing to achieve sub‑micron form, <8 µin Ra surfaces, and geometric alignment impossible by milling alone. Controlled temperature, air‑bearing spindles, and SPC‑driven gauging hold ±0.0001‑in size and 0.000020‑in roundness on hardened steels, carbides, Inconel, and titanium—delivering flight‑critical bores, tooling dies, and seal surfaces fully certified for aerospace, medical, and semiconductor assemblies.

Polishing / Grinding encompasses abrasive stock-removal and surface-refinement operations applied after rough machining or heat treat. Grinding with bonded-abrasive wheels (Al₂O₃, SiC, CBN, diamond) brings parts to final size, geometry, and flatness, routinely holding ±0.002 mm and roundness < 0.001 mm on hardened steels > 60 HRC. Subsequent polishing stages—belt, buff, super-finishing, micro-finishing, or lapping—reduce surface roughness to Ra 0.05 µm–0.20 µm, produce plateau finishes for bearing surfaces, or achieve mirror cosmetics before coating or plating. Coolant-flooded machines, automatic size-control gauging, and filtered oil or water emulsions ensure thermal stability and contamination-free finishes for aerospace, medical, mould-and-die, and precision fluid-power components.

Polishing / Grinding

Closed-loop contour and form grinding on CNC jig grinders achieving ±1 µm positional accuracy and < 0.4 µm Ra surface on hardened tool-steel cavities and punch profiles.

CNC Jig Grinding

OD / ID Cylindrical Grinding uses precision cylindrical grinders to finish external (OD) and internal (ID) diameters to sub-micron accuracy. The workpiece is held between centers or in chucks while abrasive wheels traverse or plunge-feed to achieve tight roundness, concentricity and mirror finishes. Match-grind capability produces mated shaft/bore sets with controlled clearance or interference fits, supporting aerospace, medical and gauge manufacturing.

OD / ID Cylindrical Grinding

Precision Flat Surface Grinding uses abrasive wheels to create exceptionally flat and smooth surfaces on a workpiece, crucial for applications requiring tight tolerances and high surface quality.

Precision Flat Surface Grinding

Honing refines geometry, surface texture, and dimensional accuracy using abrasive stones, typically in cylindrical forms (e.g., engine cylinders, hydraulic bores). This precise finishing process is vital in industries requiring tight tolerances.

Honing

Plateau honing or abrasive super-finishing of cylindrical bores to Ra ≤ 0.1 µm, taper < 2 µm and cross-hatch 40–60° for extended seal life and oil retention.

Bore Super-finishing / Micro-Honing
