A benchtop ultra-precision diamond lathe combining turning, milling and grinding. Built for infrared lenses, optical mirrors and precision moulds of φ80–100 mm aperture: mirror turning, milling and grinding complete in a single set-up. Suited to laboratories and small production lines.

• Consumer electronics
• Precision molds
• Turn-mill-grind integrated

Vertical spindle layout with the workpiece face up, for nanometre-level face and curved-surface turning of φ10–200 mm small and medium face parts and precision components. Granite base, full-closed-loop nanometre grating, active vibration isolation and precision thermal control; X/Z two axes or X/Z/B three-axis interpolation. The B axis keeps the cutting point fixed, markedly reducing the effect of tool arc error on form — ideal for steep aspheres.

• Vertical face-turning integration
• Three-axis fixed-point turning
• Sub-nanometer dynamic accuracy
• Cost 1/3–1/2 of imported equivalents

X/Y/Z direct-drive linear motors and a continuously indexing C-axis torque motor turn gratings and micro-structure arrays with 140–180 μm period and 20–50 μm groove depth directly into 1060×940 mm nickel substrates. Forty-five 20×20 mm cells are seamlessly stitched in four-axis interpolation to cancel accumulated error, reaching an optical-grade mirror in one pass with no polishing; after first- and second-order straightness compensation the diffracted wavefront PV improves to about 83 nm.

A dedicated horizontal roller-engraving machine for high-aspect-ratio rollers: 1200 mm working length, Φ300 mm diameter, workpieces to 1 t. It mirror-turns micro-nano imprint rollers, grating master rollers and security imprint rollers in one set-up over the full length, avoiding segmented tool marks.

An ultra-precision horizontal lathe for medium and large flats and spheres up to Φ320 mm. X/Z direct-drive linear motors, hydrostatic or air-bearing guides and full-closed-loop nanometre grating hold spindle axial and radial runout to ≤15 nm.

• Large-aperture flats
• Spherical and aspheric
• Infrared windows

A benchtop footprint with laboratory-grade accuracy. The machine occupies less than one bench and suits prototype development, process validation and small-batch nanometre turning; with low site and utility requirements it deploys quickly into university and research laboratories.

An ultra-precision flat grinder with a vertical-spindle rotary table: table axial runout 0.000050 mm, ground surface Ra 0.05 μm, table rotational accuracy 0.05 μm (50 nm). It mirror-grinds hard and brittle materials — ceramics, glass, sapphire, cemented carbide and semiconductor substrates — with stepless table speed from 0.000001 to 30,000 r/min and loads of 0.1–500 kg.

Built on the GM3207B platform with an IC-specific cleanroom interface, dedicated coolant system and in-line inspection, for back-thinning wafers up to 12 inch: wafers thin to below 100 μm, the Φ320 table covers 12 inch, surface Ra 0.05 μm, table axial runout 0.000050 mm.

Multi-beam interference from an ArF excimer laser (193 nm) exposes nanometre-period fringes directly, with no conventional photomask: feature linewidth ≤55 nm, linear grating period ≤120 nm, 4-inch wafers, effective pattern area ≥94 mm, intensity uniformity ≤2% and alignment accuracy ≤0.8 μm. Changing the pattern means changing the optical path and phase mask — no new chrome mask set.

The final form of a single-point diamond-turned surface is set by spindle rotational accuracy and guide straightness. Guangbo Technology builds every air-bearing spindle, guide and rotary table in house: machine and component share one origin, the accuracy chain contains no third-party black box, and customers can buy the components separately as drop-in replacements for imported units.

A high-speed air-bearing spindle that is both air-supported and air-driven: 0.1–120,000 rpm, maximum dynamic runout DRO 0.1 μm at 300 rpm, synchronous radial deviation below 1 μm and asynchronous below 0.25 μm, with an ER11 self-centering collet clamping up to 6.35 mm.

An air motor spindle rated to 200,000 rpm. Factory measurements: axial float 5 μm, static deviation ≤1 μm, dynamic deviation ≤6 μm and collet engagement 99% — static and dynamic accuracy both better than the standard values.

1–300,000 rpm, drilling from 0.05 mm to 6.35 mm; 750 W continuous output, 700 W water-cooled dissipation, reluctance/TTL speed sensing — for micro-hole drilling and micro-tool grinding.

Radial and axial rotational accuracy both ≤0.05 μm, power from 0.5 to 6 kW, radial and axial load capacity above 40 kg (customizable), air or water cooling — for heavy-duty precision grinding and large optical components.

800 W at 220 V, stepless 0–24,000 rpm, ER11 collet for 1–7 mm shanks, Ø65 mm body 195 mm long with a 35 mm collet section, net weight 2.8 kg. Grease-lubricated and water-cooled; a VFD is required.

A high-speed drilling/milling motor spindle in three ratings, 6.00 / 5.50 / 4.50 kW, all at 380 V, 18,000 r/min and 0.1 μm rotational runout, with an ER32 spindle nose, IP54 protection, air cooling and manual tool change.

Cylindrical shaft with an air-bearing slide, in single- or dual-slide configuration: positioning accuracy ≤0.1 μm, displacement accuracy ±0.2–0.5 μm, guide stiffness 8 kg/μm, maximum acceleration 5G, radial load 0.1–600 kg, travel 500–2000 mm in 11 standard steps and customizable to 4000 mm.

A short-travel precision stage with dual-layer aerostatic support: closed-loop positioning ±50 nm, repeatability ±20 nm, minimum step increment 1 nm, motion straightness and flatness ≤0.1 μm per 25 mm, non-contact air gap 8–15 μm, with a 0.1 nm / 1 nm nanometre grating scale.

The ABR standard series covers six platter sizes from φ120 to φ300 mm with axial runout <0.1–0.3 μm, radial runout <0.1–0.4 μm and 300–2000 N load capacity, plus full-circle grating indexing better than ±1″. Above φ300 mm, tables are customized up to φ1000 mm.

Spindle accuracy ±0.035 μm, system accuracy ≤0.05 μm, resolution 0.01 μm and up to 8192 points per revolution. It measures roundness, waviness, concentricity, coaxiality, parallelism, flatness, squareness, eccentricity and runout; effective table diameter is 200 mm on the GP326H, 256 mm on the GP316H and 300 mm on the GP306H, with a 450 mm measuring height.
