US Concepts CSR-750CNC Automatic CNC Stair Router

CALL FOR AVAILABILITY 

The CSR-750CNC Stair Router is designed for high speed precision trenching and open stair cuts. To make the operation of this machine as easy as possible for use by any operator, the CNC unit is pre-programed for most stair routing applications. However, the CSR-750CNC still retains full capability of programming using standard CNC codes.

The operator simply chooses the stair style from the 5 preprogrammed styles, enters the rise, run and number of stairs, insert the pair of boards and then presses the Cycle Start button. Two high speed router motors simultaneously route both the left and right hand stringers with dovetail bits from above and below the boards. One of the 5 preprogrammed styles included is the capability of cutting the open stringer and open stringer with 45ï‚° miter riser relief (changing of the top & bottom router bits is necessary).
