Secure and adaptable workholding for irregular and large components
Aufspann sets, also known as clamping sets or prong sets, provide modular and universal workholding for machining tables with T-slots, enabling the rigid fixation of complex, irregular or very large workpieces that cannot be held in a standard vice. By combining adjustable support jacks, clamping prongs and T-slot nuts, these systems permit precise placement of clamping force to resist high radial and axial cutting loads and prevent distortion of the part; materials are commonly high-strength quenched and tempered steel for long-term durability. Ideal for jobbing and small-series metalworking, these sets deliver exceptional setup flexibility and fast, secure fixturing for castings, large plates and welded assemblies, protecting tool life and improving machining accuracy.

Flexible clamping for irregular and oversized workpieces
Clamping kits, often referred to as clamping sets or workholding kits, are modular mechanical aids designed for rigid workpiece fixation on milling and drilling machine tables with T-slots. Used everyday in workshops, these kits let machinists secure complex, irregular or very large components that cannot be held in a conventional machine vice.
How these systems work and where they are indispensable
A clamping kit combines adjustable supports and robust clamping elements to place force exactly where it is required. By pairing adjustable screw jacks as counter supports with sturdy clamp jaws for force transmission, the system counters both radial and axial cutting forces and prevents bending or movement under heavy loads. This makes clamping kits indispensable for single-part and small-batch machining, repair work and fabrication tasks on the machine periphery.
Measurable benefits you see at the machine
- faster, repeatable setups and reduced machine downtime
- precise placement of clamp pressure for improved machining stability
- reliable fixation under heavy radial and axial cutting forces, increasing process consistency
- adaptable clamping for castings, large plates and bulky welded assemblies
- durable components for long service life and fewer replacements
