The Schmalz Alu-Blocksauger VCBL-K2-HD 170x128x100 is the large-area high-performance block suction cup for CNC machining centres with 2-circuit console system — in heavy-duty aluminium construction, freely rotatable through 360° in 15° increments.

With its particularly wide contact surface of 170 × 128 mm, it offers maximum contact area with the workpiece and thus maximum holding force for large and heavy panels — ideal for demanding milling, drilling and 5-axis machining operations where smaller block suction cups reach their limits.

More surface. More hold. More safety — even with large-format workpieces.

When is this block suction cup the right choice?

• Large-format workpieces: The 170 × 128 mm contact surface offers significantly more holding force than smaller VCBL-K2 variants — ideal for panels from 600 × 400 mm
• Intensive milling operations: With high feed rates, deep plunges or strong side loads, the large surface ensures secure holding without slipping
• 5-axis machining: 360° rotation in 15° increments enables optimum workpiece alignment for complex machining angles
• Upgrade to a larger contact surface: As a replacement for smaller block suction cups when holding force is insufficient for existing projects
• Hardwood and composite materials: Maximum safety thanks to the 2-circuit system, even with particularly heavy or difficult-to-clamp material

Advantages of the 2-circuit system

• Double safety: Two separate vacuum circuits hold the workpiece securely even if one circuit becomes leaky
• Higher holding force compared with 1-circuit suction cups — essential for heavy panels and intensive milling operations
• 360° rotation in 15° increments for maximum flexibility during setup and optimum workpiece alignment
• Heavy-Duty aluminium housing for the longest service life, even under heavy use and chip impact
• Tool-free height adjustment thanks to the Schmalz stepped system — quick changeover without a key
