ALUMA MILL 3518

Compact yet precise. No more settling for mediocre desktop milling.

For years, desktop machine tools have long been dismissed as mere “hobby trial cutting toys”, plagued by insufficient rigidity and inconsistent precision. The ALUMA Mill 3518 arrives to dismantle this outdated prejudice once and for all. Equipped with our self-developed 1605 zero-gap ball screws module, it locks positioning accuracy approximately 0.01 mm.

Paired with exclusive 50160 high-rigidity aluminum extrusions, mechanical resonance is physically suppressed throughout the machine frame. Even when machining aluminum alloys, it maintains exceptional stability. Its fully enclosed protective enclosure also saves you the trouble of cleaning aluminum chips splattered all over the worktable.

This machine stands to prove one core truth: industrial-grade performance and dignity can be achieved right on your desktop.

This is not merely an upgrade—it is a qualitative leap from mere rotation to ultimate precision.

The ALUMA Mill 3518 was engineered with one pure objective: to deliver pinpoint, industrial-standard machining on a desktop platform.

We reject cheap lead screws as standard fitment, instead equipping it with 1605 precision ball screws module that deliver nearly zero backlash. The frame adopts customized 50160 aluminum extrusions with optimized rigidity-to-weight ratio, eliminating frame wobble during heavy cutting operations. Most critically, full sheet metal guarding supports both dry and wet cutting freely, with zero risk of coolant splashing onto internal circuit boards.

This is not a minor upgrade — it marks a fundamental transformation from a machine that merely “rotates cutters” to one that reliably gets demanding industrial jobs done.

Compact size, full-grade specs. We redefine what a desktop CNC truly stands for.

The ALUMA Mill 3518 easily conquers the tough machining properties of aluminum alloys, confining machining precision approxi. ±0.01 mm tolerance threshold.

Though compact in size, it makes zero compromises on industrial specifications. This is our redefinition of what a “desktop machine tool” is capable of.

The ALUMA MILL 3518 is a compact high-precision desktop CNC milling machine designed for engraving, drilling, and light milling applications. Featuring a rigid aluminum frame structure, HGR20 heavy-duty linear rails, and SFU1605 precision ball screws, it provides excellent stability and machining accuracy.

It is 100% fully self-developed, designed by BulkMan3D International R&D Team in 2026 and copyrighted by BulkMan3D.
