Solving the Clamping Challenge for Irregular Workpiece Machining
Our project addresses the challenge of clamping irregular-shaped workpieces, which cannot be effectively positioned using traditional 3 jaw or 4 jaw chucks. Since the core task is precision boring of the inner diameter, achieving accurate centering is critical: misalignment leads to eccentric cutting and dimensional errors, severely impacting machining accuracy and stability.
To overcome this, we adopted a Finger Power Chuck (2J) with a compensating jaw mechanism. Originally designed with a rotational down press motion for vertical positioning and clamping, the chuck’s rotation could interfere with the auxiliary centering fixture.
Therefore, we reconfigured the jaw actuation sequence: centering is first accomplished by the auxiliary fixture, after which the Finger Power Chuck(2J) performs vertical clamping. This ensures precise centering and significantly improves turning stability and machining quality.
Custom-Designed
Jaws and Support Plate for a Perfect Fit
Supporting this application, we developed custom jaws and a matching support plate to conform precisely with the workpiece’s end face and locating holes. This ensures instant centering at the moment of clamping, while preventing lateral slipping or lift during machining—thereby enhancing clamping rigidity and operational safety.
