Depending on the size of your workpieces and the position of the spindle or fixture in the machine, Coby needs the door opening to be at least 470mm wide. That allows Coby to move in and out of your machine while holding a workpiece which is up to 20mm high. For workpieces which are up to 100mm, the door needs to be 550mm wide. Read more about door opening requirements in the installation guide.
