APSX SPYDER CNC Machine can cut ALUMINUM, STEEL, BRONZE, BRASS, DELRIN (ACETAL), WOOD and other plastics with high precision.
Portable CNC MachineAPSX SPYDER is a precise and rigid CNC milling machine that can cut metals, wood and plastic. It fills the void in the market for CNC routers to cut specifically metals not just wood. APSX SPYDER is a complete system that includes configured LinuxCNC, embedded PC, monitor, keyboard, and pendant. There is nothing else you need to start milling parts. It also uses a standard wall outlet for the control box and monitor.
Metal cutting requires specific cutting speed vs. spindle speed ratios for quality machining. Most air-cooled routers are rated between 10,000 and 30,000 RPM. They usually have low torque on the low end of the RPM range.
Keeping temperature as low as possible around the cutting environment including the spindle, end mill and workpiece is critical for cutting metals. Water cooled spindles do a better job than anything that is air cooled. APSX SPYDER has a liquid-chilled spindle with a wide range of RPM, 2000-20000 and high torque at low speeds. It can keep the RPM constant and controlled using G-Code.
APSX SPYDER uses a water air mixing system to facilitate cooling both the workpiece and the end mill. Without cooling, machining metals becomes harder as the temperature increases. At some point aluminum will gum up the end mill and will stop cutting effectively or at all. This can sometimes damage the end mill and it is difficult to remove molten plastic on it. Pressurized air mist also helps to remove the chips before any gumming occurs.
If an aggressive cutting strategy is used or if there is not enough coolant, the spindle may be forced above its abilities. APSX SPYDER is able to detect and stop motion before further damage is imposed on the workpiece and the end mill. It will also keep XYZ coordinates so you can continue machining without homing.
APSX SPYDER has steel shafts, hard anodized aluminum blocks, precision lead screws and strong stepper motors making it a very rigid machine. Its rigidity is more comparable to vertical machines than CNC routers. The optional solid concrete base adds extra rigidity for higher precision milling.
