Engraving Spindle
Standard 800watt (1HP) spindle with a depth regulating nose attachment. The spindle can be locked after the floating attachment has been removed. Depth adjustments made by turning a knurled wheel.

High Frequency Spindles
Available in various sizes, the High Frequency (HF) spindles offer a variable speed controlled by an electronic frequency drive. The HF spindles have upgraded bearings with less runout over the life of the spindle. These spindles are more expensive than the 800watt spindle, but for production work they offer less downtime and the ability to take a larger cut without loading down the motor. The HF spindles use typical ER 20 collets.

2D Vacuum Shroud
Floating vacuum shroud. Placed on the Z axis around the cutter, this floating shroud eliminates most of the chips created in the cutting area when connected to a vacuum system.

Tool Sensor
Included with all CharlyUSA machines, the Tool Sensor compensates for the difference in the length of cutting tools being used. When installed, the machine will plunge down and the cutter will touch the probe sensing the length of the installed cutter.

Automatic Tool Changer
(Not available on the 4U machines). The tool changer on the 2U has 5 different tool locations. The tool is located in a holder and placed in the changer. When the program prompts for a different tool, the machine moves to the existing tool location and unloads the tools then moves to the new location and inserts the new tool

Remote Control Pendant
Allows the user to manually control the machine without going to the computer. Setting the offset location for machining, jog speed and jog directions are all done with separate buttons on the pendant.

Micro-Lubrication
The micro-lubrication option provides an adjustable mist directly to the bit, providing a cooling effect without the use of flood coolant. We recommend this option when extensively machining metals.

Vacuum Table
Allows for holding down of sheet components on MDF or a porous material. The vacuum hold down is placed on the bed of the machine and a switch is placed on the faceplate of the machine allowing the user to select whether the vacuum switches on manually, automatically with the spindle, or if the vacuum is disabled.

800 Watt Spindle
Variable speed spindle operating at 10,000 – 30,000 RPM. The speed is controlled by a potentiometer on the front panel of the machine. Typically an excellent and affordable option for prototyping and non-production work.

4th Axis
Rotary axis for 2U and 4U machines. The rotary axis is a horizontal rotary along the X axis. This allows for double sided machining or constant rotary machining. The Rotary axis comes with a 4 jaw chuck and a tailstock. The 4th axis on the 4U machine takes most of the work area but on the 2U machine, you still have work area for standard 3 axis machining when the 4th axis is mounted.

Air-Cool Option
Instead of using a fine mist, the air-cool option is a dry system using compressed air thru a vortex tube. The air coming out of the vortex is far cooler allowing for a longer tool life.
