CNT Motion CNC Stair Stringer Machine

CNT-1000 Dual-Head Stair Stringers and Treads Machine

CNC Stair Stringer MachineSince 1992, CNT Motion has been building machines for cutting stair stringers and treads. Our standard CNT-1000 Stair Stringer Machine has two individually programmable X-axes, each attached to a Z-head for mirror-image and split-head machining to optimize material for the best possible yield. A custom software program allows you to pick material type and thickness, rise and run, style of stringer (box, open, horse cut, winder, etc.) and end cuts. Also available in our CNT-950 configuration.

WinStair, Stringer Gcode Generator

Apply your specifications and generate Stair Stringer G-Code in seconds. WinStair supports tool changers and stored confgurations to meet the users specifications. This software can be setup to use a machine with a single router, or for a machine with dual routers for faster production. Different types of stair stringers can be setup parametrically and again the GCode is sent directly to WinCNC. There is also a batch option where a spreadsheet of stringers can be loaded automatically and then the user can select the groups of stringer to cut. A materials list is also imported and the stringers are grouped to reduce material waste. This software also has an add-on that automatically prints custom labels on a label printer.
