Note: Tooling is not included in the sale but can be purchased separately or newly manufactured at additional cost. The machine is based on the DRZ1250 platform; however, the currently installed main drive shaft limits the usable machining length to approximately 680 mm. Installation of a new drive shaft would increase the usable length to approximately 1,050 mm.
