Wood doors prehang machinery

The KVAL Company manufactures door hanging machinery. Their DL-NCB numerically-controlled door light cut out machine is designed to rout lock face holes, viewer holes, and lights in exterior doors made of fiberglass, steel or wood. Features on this machine include automatic door positioning and routing cycle for lock face holes and door light cut outs.

Their 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 steel, fiberglass or wood doors. Tool change is automatic or can be performed manually with the computer keeping track of tool characteristics. The tool magazine holds 6 cutters with two chucks provided as standard.

The standard DL-NCB is configured for residential steel or fiberglass doors, with capacity ranging from 12” wide sidelights to doors up to 4’ by 8’. An option is available to increase the capacity of the DL-NCB to accommodate doors up to 10' high.
This machine is equipped with a single, variable speed, high frequency motor. A precision tool holder chuck is mounted on the motor shaft. They also include a six position tool holder on the DL-NCB with chunks and programming to automatically change the tooling as needed.

Programming can be 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 Windows based screen ware to include regular shapes, rectangles, circular, or multiple cuts. Programs for irregular curves, ovals or reversing arcs may be ordered as an extra.
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.
