Schunk Inc. has introduced the Kontec KSC – a multi-functional manual clamping system. The unit is easily and quickly adjusted, whether for conventional clamping, very low clamping depths for 5-sided machining, molded parts, plates or workpieces with saw cut surfaces.
Its design facilitates the assembly of high supporting jaws for 5-axis machining. The clamping module is easy to actuate with a torque wrench and can be aligned on the machine table via longitudinal and transverse slots. It can easily be modified from a centric clamping device to a clamping module with a fixed jaw.
The base body of the Kontec KSC is equipped with an integrated coolant groove. To reduce set-up time, the module can be retrofitted with a Schunk Unilock quick-change pallet system. The clamping force is 25 kN, the jaw width 100 mm and the clamping width 292 mm, depending on the type of top jaws.
The new power grip jaw lets the operator increase the clamping force to 35 kN at the top of the jaw, where the jaw meets the workpiece. This feature offsets typical clamping force losses due to tall jaws. In addition, the company said the power jaw is the optimum way to clamp workpieces for 5-axis machining because the KSC lifts the part to provide needed tool clearance. Additionally, the power jaw is ideal for clamping high-strength materials.
