VEVOR CNC Router Machine, 500W Spindle, 3-Axis Wood Engraving Milling Machine, with Dual Linear Rails & Ball Screw, 15.75 x 15.75 x 3.74 in Working Area, Trim Router, for Wood Acrylic Carving Cutting

Yes, this 500W spindle CNC is capable of milling 1/4" aluminum plate, but it requires much slower feed rates and shallower passes than wood. The dual linear rails and ball screws provide the necessary rigidity to handle the lateral forces of cutting aluminum without excessive vibration. For slotted holes and grooves, use high-quality carbide end mills and take passes of 0.1mm to 0.3mm to ensure a clean finish and prevent tool breakage.

It is essential to use a lubricant or mist coolant during the process to keep the aluminum from melting and sticking to the cutting flutes. Since elevator bolts require precise flat-bottomed grooves, this 3-axis machine is well-suited to create the exact depth needed for the heads to slide freely.

Candle software included, ready to use right out of the box. This 500W CNC engraving machine comes with Candle control software and supports Mac/Windows/Linux systems. Candle is an open source control software based on GRBL firmware. It has a simple interface and is suitable for beginners.

It is ER11. You can easily buy different size collets on Amazon, just make sure they are ER11 size.

You can just buy an ER11 1/4-inch collet.

If the milling cutter used can cut a thickness of about 1.8–2 cm, if it is a pointed cutter then it is around 1–1.5 cm. However, one point to note is that the Z-axis single plunge feed rate should not exceed 2 mm. For example, a material with a thickness of 1 cm needs to be cut through in at least 5 passes.
