CNC machine for precise wood, metal and acrylic cutting, offering a generous work area and low-vibration motion, the SainSmart Genmitsu CNC Machine 4040-PRO MAX. Confident, repeatable results help small workshops and makers complete intricate projects without constant rework. Is the build quality and upgrade path right for a growing workshop?
⚡ At a Glance
- • Cutting Quality: Stable motion from SBR16 linear rails and a lead screw, reducing vibration for cleaner cuts
- • Best for: Small workshops, makers and hobbyists needing repeatable precision for wood, metal and acrylic work
- • Not ideal for: Large-scale industrial production or very heavy milling tasks beyond a compact router's capacity
X-axis uses SBR16 linear rails with a lead screw to reduce vibration and improve motion stability. Repeatable positioning accuracy is ±0.005 mm, suitable for intricate surface carving.
Stable, accurate cuts - Thanks to SBR16 linear rails and lead screw
SBR16 linear rails on the X-axis combine with a lead screw to reduce machine vibration and improve motion stability during high-speed engraving. That configuration keeps the router tracking consistently across the work area.
Reduced vibration produces cleaner edges and tighter tolerances, useful when cutting detailed shapes in wood and acrylic.
Repeatable vertical precision - With lead screw and linear rails on the Z-axis
The Z-axis uses a lead screw paired with linear rails to enhance vertical motion stability and lower vibration, yielding a repeatable positioning accuracy error of ±0.005 mm.
Consistent depth control supports intricate surface carving and reliable batch runs without constant re-adjustment.
Handle taller, tougher jobs - With 100 mm pass height and 710W router
A 100 mm pass height increases clearance by over 40% compared with the PRO version, and a compact 710W trimmer supplies higher cutting power for demanding tasks.
Ability to work on thicker stock and tougher materials reduces tool changes and speeds up project turnaround for makers and small shops.
✨ The 4 Key Reasons for SainSmart Genmitsu CNC Machine 4040-PRO MAX
