CNC Mill System, Light Duty (5400)
The CNC mill can machine pieces of soft materials, such as wax and Plexiglas, as well as harder materials, such as aluminum and brass.
The CNC Mill consists of a milling table, a headstock carrying the spindle motor, and a vertical column with dovetail slide.The stock can either be mounted directly on the mill table or secured in a vise that holds it to the table.
Two lead screws, each driven by a stepper motor, are used to move the table along the X axis (left and right) and Y axis (backward and forward) to feed the stock through the periphery of the end mill.
A third lead screw, also driven by a stepper motor, is used to move the headstock along the Z axis (up and down) for positioning the end mill.
The speed of each stepper motor can be programmed separately for feed rates up to 356 mm/min (14 in/min). A 160-W (0.21-hp) motor rotates the spindle at speeds programmable up to 2800 r/min.
The end mill can be changed to accommodate different stock materials and milling designs. A computer (not included) is used to create NC part programs with the G and M machine codes or their conversational code equivalents. The created programs are downloaded to the on-board microprocessor of the CNC mill, which stores and executes them.
