CNC Machines — Factory Direct from Shenzhen, China

The SZGH-540 is a compact vertical CNC milling machine engineered for high-mix, small-batch production — a 1,900 kg anti-deformation base in a 1,350×1,050 mm footprint, letting one operator run two or three machines simultaneously and cut per-part labor cost without sacrificing rigidity or accuracy.

The SZGH-540D is the high-speed electric spindle variant of the SZGH-540 platform — a compact CNC milling machine that ships with a 24,000 RPM electric spindle and an 8-station BT30 tool magazine as standard equipment. Where the SZGH-540 offers a mechanical spindle (6,000 RPM, 3 kW) with ATC as an optional add-on, the 540D comes pre-configured for high-speed aluminum, copper, and light alloy machining from the first part program: electric spindle loaded, tool magazine installed, ready to run automated multi-operation cycles without additional configuration. The 540D retains the 540's 1,900 kg anti-deformation base, Taiwan 25 mm P-grade ball screws, Taiwan Precision C3 linear rails, and 500×400 mm work envelope. The difference is the spindle assembly: a 4.5 kW electric spindle integrated directly into the spindle cartridge — no belts, no gears, no mechanical transmission — delivering 24,000 RPM with lower vibration, tighter runout, and better surface finish on aluminum and non-ferrous materials compared to mechanical spindles at the same speed range. Combined with the standard 8-station servo ATC, the 540D enables fully programmed multi-tool cycles — drill, tap, face mill, contour mill — without operator intervention per part. For shops whose primary production is aluminum alloy housings, copper electrodes, brass fittings, electronics enclosures, or precision fixtures, the 540D eliminates the decision of whether to add the electric spindle and ATC options. Both come as standard.

The SZGH-650 bridges the gap between compact CNC mills and full-size VMCs — a 2,900 kg anti-deformation base, BT40 spindle taper, 32 mm precision ball screws, and a standard 10-station servo tool magazine deliver mid-range machining center capability in a footprint small enough for one operator to run two machines simultaneously.

The SZGH-650D is a small vertical CNC milling machine built around a 24,000 RPM electric spindle — the high-speed variant of the SZGH-650 platform, engineered for manufacturers whose primary production involves aluminum alloy, copper, brass, engineering plastics, and other light-to-medium materials where maximizing surface speed, minimizing tool deflection, and achieving fine surface finishes take priority over heavy-duty low-speed torque. Where the SZGH-650 uses a mechanical spindle (BT40, 6,000 RPM standard) optimized for steel drilling, stainless steel face milling, and cast iron work, the SZGH-650D replaces the mechanical spindle assembly with a 7.5 kW electric spindle unit rated at 24,000 RPM with BT30 taper — delivering the high surface speeds that aluminum alloy machining demands for chip evacuation, tool life, and surface finish quality, without the resonance and heat buildup that mechanical spindles generate at high RPM. The 650D ships with a 12-station servo tool magazine as standard — two more stations than the standard 650 — and achieves ±0.01 mm repeatability across the 600×500 mm work envelope, making it suited to multi-operation aluminum programs where dimensional consistency across large batches is a production requirement.

A heavy-duty 30° slant bed CNC turning machine for high-volume batch production of precision parts up to Ø35mm bar stock — 400kg heavier than entry-level 25mm lathes, with a 4kW spindle, two-axis Harbin angular contact bearings, and the self-developed SZGH control system. The direct replacement for aging hard-rail and hydraulic automatic lathes in metal workshops upgrading to automated production.

A heavy-duty 30° slant bed CNC lathe for high-precision, high-rigidity turning of large parts — 45mm bar stock capacity, ±0.0075mm machining accuracy, 5.5kW servo spindle, 3,000kg anti-deformation cast base, and SZGH's self-made high-rigidity barrel spindle unit. The precision step up from the 36-series, built for demanding aerospace, medical, and automotive applications where tighter tolerances are non-negotiable.
