General Information

In order to make operation of this machine as easy as possible for use by low skill operator the CNC unit is preprogrammed for most stair routing application. However, the CSR-750CNC still retains full capability of programming using standard CNC codes.

What operator has to do is simply pick the stair style, enter the rise, run and number of stairs, insert the pair of boards and press Start button. As the machine takes over, two high speed router motors simultaneously rout both left and right hand stringer with dovetail bit. As a bonus, machine is capable of cutting the open horse stringer and open stringer with 45° riser relief
