The GT-10 starts at 70 mm or 2.7" center height and has three T-Slots on the bed. We offer 18", 12" and 6" riser plates for the GT-10 that allow you to order the best tooling options for the machine depending on the live tool option or turret option you have selected. The machines original table is 24" in X-Axis length so if you want to use tool holders on the entire travel of the models you would purchase two 12" riser plates that would cover the original t-slot of the machine. This flexibility allows us to install much larger diameter spindles or grinding spindles on the machines and allows us to build much stronger tool holders and tooling to compliment the larger motors and ball screws of the machines. Optional center height riser tool plate tables available on request.
