Manual 4th-Axis CNC 3040 Engraving & Milling Machine | 400W Spindle, C7 Ball Screws, 160x92x100mm Travel

Product Description (For Product Page)

(Product Hero Section)

From Desktop to Micro-Workshop.
This isn’t just a small engraver; it’s a serious, precision-engineered 3040-format CNC milling machine built with components worthy of much larger industrial tools. Featuring manual rotary 4th-axis capability, C7-grade ball screws, and a powerful 400W brushless spindle, it’s designed for the maker, jeweler, or engineer who demands exceptional accuracy and rigid performance in a compact, desktop footprint.

(Key Features Bullet Points)

• PRECISION ENGINEERED: Equipped with C7 precision ball screws on all three linear axes, delivering a theoretical positioning error of just 0.0045mm over its travel for exceptional accuracy.

• MANUAL 4TH-AXIS READY: Includes a high-quality manual rotary axis, enabling intricate cylindrical engraving, fluting, and 3D contouring on small workpieces that would be impossible on a standard 3-axis machine.

• INDUSTRIAL-GRADE RIGIDITY: Built on a foundation of 3-axis linear guides supported by 12 individual bearing blocks, ensuring minimal deflection and vibration for clean, precise cuts.

• POWERFUL & ACCURATE SPINDLE: Driven by a 400W brushless, air-cooled spindle with a runout tolerance of 0.007mm at the tool taper, guaranteeing fine surface finishes and prolonged tool life.

• SERIOUS DRIVE SYSTEM: Powered by NEMA 23 (57 frame) stepper motors for reliable torque and precise motion control across its entire 160x92x100mm working envelope.
