Rugged CNC router is easy to use - Scanning for Ideas

The HD Series CNC router from Techno Inc., New Hyde Park, N.Y., features solid construction with a base frame made from heavy-duty tubular steel that is welded, machined, and stress relieved to ensure the base remains true and steady over the machine’s life. The gantry is also made of tubular steel with reinforcing ribs welded throughout the length of the column.

All electronics are housed in a doubledoored NEMA-4 enclosure. This lets technicians easily get into the cabinet to work on power connections. The enclosure can also serve as a work table.

The router uses several motors, including a 4-hp high-speed spindle drive, a 10 hp unit powering a rotary-vane vacuum pump, and a series of brushless stepper motors that serve as the machine drives. The axes run on precision THK rails and bearings for smooth, play-free motion. The spindles use industry-standard ER collets which are fully programmable from 6,000 to 18,000 rpm. The vacuum plenum table is multizoned, letting operators switch from full-sheet processing to smaller part processing. Zones can be turned on or off using control valves on the front of the router. Gasketing can also be routed to accommodate various material sizes and styles.

Technicians can learn how to install, set up, and use the router by reading a series of step-by-step manuals. Most machine functions can be controlled through a user-friendly handheld controller.
