KVAL's DL-NCB Numerically-Controlled Door Light Cut-Out Machine is designed to rout lock face holes, viewer holes, and lights in doors made of fiberglass, steel or wood. Features include automatic door positioning and routing cycle for lock face holes and door light cutouts.

The High frequency spindle option provides a three phase 11 HP Columbo motor and variable frequency inverter. Spindle speed and tool are selected by the computer program corresponding to the door type, e.g. steel, fiberglass or wood. Tool change is fully automatic or can be performed manually. The computer keeps track of tool characteristics. The Tool magazine holds six cutters with two chucks provided.

The standard DL-NCB is configured for residential steel or fiberglass doors, with capacity ranging from 12” wide sidelights to doors up to 4’0” wide by 8’0” high. An option is available to increase the capacity of the DL-NCB to accommodate doors up to 10'-0" high. Adjustment to incoming door width is also fully automatic.

The DL-NCB is equipped with a single, variable speed, high frequency motor. A precision tool holder chuck is mounted on the motor shaft. Also included on the DL-NCB is a six (6) position tool holder with chunks and programming to automatically change the tooling as needed.

Programming is done from the operator’s console, or from a personal computer in the office via an Ethernet connection. It requires only a few minutes to create a new program for a new cut-out specification by filling in blanks on the Kval Windows based screen ware. These include regular shapes such as rectangles, circular, or multiple cuts. Programs for irregular curves, such as ovals or reversing arcs may be ordered from Kval for a charge.

Maximum shape sizes are limited to within 3” of the door’s top, and 1-1/2” from the stiles. Once these shapes have been entered and saved, they may be instantly called up and placed on a run-list. If created in the office, the run-lists can be transferred over a standard PC network.

The DL-NCB may also be equipped with an option to add barcode scanning hardware to the machine with integration of the scanner input into the computer.

KVAL can work with a company’s data processing department to further automate the generation of run-lists through the use of barcode reading or other means of interface with a customer’s existing order entry system.
