KL-1212

Overview

The KL-1212 is a three axis (XYZ) CNC router with a 48in x 48in cutting area.

Machine anatomy

The machine consists of:

• Base table; provides a flat horizontal surface for the material to be cut; has recessed T-track grooves to accommodate hold down hardware.
• Gantry; moves the cutting tool in the Y-axis (front/back) direction
• Toolhead assembly; moves the cutting tool in the X-axis (left/right) direction
• Z slide; moves the cutting tool in the Z-axis (up/down) direction
• Water-cooled Spindle; a more powerful and quieter tool, and used in place of, a router
• Controller box, which connects to the computer that is supplying the cutting instructions, and contains the stepper motor drivers, break out board, and a power supply.
• Fountain pump and water reservoir; provides cooling to keep the spindle from overheating
• Step Up/Down transformer; Changes mains voltage to 220v; The control box plugs into this.

The cutting tool on the machine is a water-cooled spindle motor with a variable frequency driver. According to the manufacturer, the machine's accuracy and repeatability is within 0.002in.
