Floating chuck with a parallel float mechanism for perfect reaming processing.
What is a floating chuck? When using a reamer on a lathe, it is necessary to correct the misalignment between the chuck and the axis of the pilot hole. This misalignment can be corrected by using a floating chuck with a self-centering mechanism. The floating chuck perfectly aligns the axis of the reamer with that of the workpiece's pilot hole, allowing for machining with the reamer's inherent precision. Advantages of a floating chuck The excellent self-centering mechanism prevents tapering of the hole and enlargement of the hole diameter, thereby improving the surface accuracy of the hole. Problem-solving with a floating chuck By increasing the speed of reaming, productivity is enhanced. This is due to improvements in surface roughness and hole accuracy. Additionally, because the reamer wears evenly during machining, tool life is significantly extended, allowing for machining over long periods without a loss of precision.

basic information
The technical mechanism of the floating chuck The parallel float mechanism corrects the misalignment between the reamer and the workpiece's pilot hole. The structure of the special ball bearings and axle drive shaft incorporated in the floating chuck enables smooth floating in both vertical and horizontal directions even during high-torque reaming operations. In machine tools such as semi-automatic lathes, Swiss-type lathes, or boring machines, achieving perfect surface accuracy in hole processing with a reamer is very challenging. This difficulty arises in the case of semi-automatic lathes due to spindle expansion during machining, while in Swiss lathes, it is generally due to wear.

Applications/Examples of results
The floating chuck solves the following problems during reaming: - Misalignment between the pilot hole and reaming - Increased hole dimensions - Conical shape of the hole (widening at the entrance) - Conical shape of the hole (widening at the bottom)
