1st MTA explains that the automatic system, which maximises spindle uptime, uses a deeper clamping head to accommodate the low pressure (35 bar) hydraulics, and a mounting plate with dedicated adapter to suit the 3-, 4- or 5-axis vertical or horizontal machining centre. Pneumatic detection of correct seating of the head ensures accurate machining and the elimination of scrap, while air blow from the underside prevents swarf from entering the mechanism during exchange.
As with the manual Swift Klamp system, the automated variant is available in HSK-A40, HSK-A63 and HSK-A100 sizes. Depending on the equipment, skills and requirements that a potential customer may have, a package is configured by 1st MTA that could include: a workpiece stocker; a 6-axis industrial robot with gripper; the Swift Klamp work-holding system with head, multiple work holders, control unit and pump; an engineered interface to the machine tool comprising electrical control circuitry and plumbing of the hydraulic and pneumatic channels through the table; and a tombstone if necessary.
The Swift Klamp system per se uses a rigid HSK face-and-taper interface, normally used for holding cutting tools, to provide a high-precision, secure, low-interference, quick-change method for clamping workpieces. Sitting on top of the interface are multiple options for holding the workpiece, including a vice, flange clamps and side clamps. Alternatively, a dovetail interface with compact clamping surface allows enhanced tool access. Billets must be pre-milled with a slot to match the holder profile using a solid-carbide cutter provided specifically for the purpose. Steel or aluminium blanks in various sizes – pre-machined with a dovetail – can also be supplied.
