The Kontec KSC from Schunk is a multi-functional manual clamping system that can be adjusted for conventional clamping; five-sided machining with low clamping depths; molded parts; plates; or workpieces with saw-cut surfaces. Its design facilitates the assembly of high supporting jaws for five-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, the company says. It can be modified from a centric clamping device to a clamping module with a fixed jaw.
The base body is equipped with an integrated coolant groove. To reduce setup time, the system can be retrofitted with a Unilock quick-change pallet system. Clamping force is 25 kN, jaw width is 100 mm and clamping width is 292 mm, depending on the type of top jaws.
The power-grip jaw enables the operator to increase the clamping force to 35 kN where the top of the jaw meets the workpiece. This feature offsets typical clamping force losses due to tall jaws, the company says. In addition, the power jaw is said to be the optimum way to clamp workpieces for five-axis machining because the manual clamping system lifts the part up to provide needed tool clearance. The power jaw is also ideal for clamping high-strength materials, the company says.
