YoraHome CrossRiver Benchtop CNC Router 6060

About the Machine

The CrossRiver Benchtop CNC Router 6060 is YoraHome's mid-size benchtop machine, with a 60 x 60 cm (24 x 24 in) working area, a 500W air-cooled spindle, NEMA 23 closed-loop steppers, and linear rails with ball screws on the drive. Its controller is an Arduino board running GRBL firmware.

Cut Settings on this Machine

Every cut starts with one formula: Feed Rate = Spindle Speed (RPM) x Chip Load x Number of Cutting Edges (flutes). Chip load is the thickness of material each cutting edge removes in one revolution of the bit. This number comes from the manufacturer of the bit, which publishes a chip-load chart for each bit diameter and material. Look up your exact bit and material, start from the middle of the published range, and you have the third number in the formula. The chart below shows the recommended spindle speed for each material and bit type.

The CrossRiver 6060 pairs closed-loop NEMA 23 steppers with linear rails and ball screws on every axis, a rigid drive system for a benchtop machine. YoraHome doesn't publish a max RPM for the 500W spindle, though, so check the rating plate on your unit against the chart. A rigid drive train like this can generally handle a deeper pass than a lighter belt-and-wheel setup, but depth per pass still comes down to spindle power: a truly rigid machine with a powerful spindle can cut as deep as the bit is wide in a single pass, while a lower-power spindle needs shallower passes to avoid trouble. Push too deep and the bit deflects and chatters, leaving scalloped edges, or it rubs instead of cutting and burns the material. The fastest way to dial in a cut is to see what has already worked for other people.

Worked example for feed rate: 1/8in (3.175mm) two-flute solid carbide end mill in hard wood. The chart says 16,000 RPM; YoraHome doesn't publish a max RPM for this spindle, so check the rating plate on your unit and use whatever it allows, up to 16,000. With the bit maker's 0.025mm per tooth (0.0010 in) at 16,000 RPM: 16,000 x 0.025 x 2 = 800 mm/min (31 in/min) feed. Scale that number down if your spindle's actual RPM is lower. For depth per pass, start shallow and check Community Cut Settings in Easel for what works on this machine. If the cut sounds strained, reduce the depth, not the feed. Slowing the feed below the chip load makes the bit rub instead of cut.

Community Cut Settings shows the spindle speed, feed rate, and depth per pass other makers actually run for your machine, material, and bit.
