V-Clamp VC4 Single-Sided Vacuum Clamp

The V-Clamp VC4 Single-Sided Vacuum Clamp is a durable and reliable clamping solution designed for CNC machining and other precision applications. This fixed, single-sided clamp must be securely mounted to a workbench or CNC spoiler board using bolts or screws, providing a stable and immovable base for work holding. Ideal for frequent use in industrial settings, the VC4 is engineered to provide exceptional clamping force without compromising material integrity. Its simple design—featuring no moving internal parts—ensures long-lasting performance and minimal maintenance.

Key Features:

• Single-Sided Vacuum Clamp: Designed to provide powerful clamping force for non-porous materials without the need for complex internal mechanisms.
• Bolted Mounting System: Requires bolts or screws for secure attachment to a flat surface, ensuring stability and preventing movement during machining.
• High Clamping Force: Ambient air pressure (800g per cm²).
• Injection-Moulded Nylon Construction: Lightweight and non-marring material that won’t damage cutters or workpieces.
• Replaceable Rubber Seal: Customisable seal ensures a tight vacuum grip, even for small or irregularly shaped workpieces.
• No Moving Parts: Designed for long-lasting reliability with minimal maintenance needs, making it the most economical option for frequent use.

Applications:

• CNC Machining: Provides stable clamping for precise cuts, engravings, and routing on non-porous materials such as wood, plastics, and certain metals.
• Woodworking: Ideal for holding various-sized pieces securely during carving, sanding, or planning operations.
• Metalworking: Offers reliable clamping for thin or delicate metal sheets without causing damage or slippage.
• Prototyping & Production: Perfect for repetitive tasks or small-batch production requiring stable and repeatable work holding.

Product Specifications:

• Product Dimensions: 160x200x22mm
• Mounting Holes: 6.5mm
• Air Consumption:  1CFM at 80psi (28l/m @ 0.6MPa)
• Weight: 325g
• Holding Force: Better than 800g per cm2 (12psi @ 80psi minimum)
• Body Material: PE/ Nylon
• Includes: 
  • • 1x Vacuum Base paired with push-fit connector ready for 6mm hose.
    • 1x 1-metre 6mm Clear hose with a Quick-fit fitting with 1/2” BSP thread compatibility with common on/off valves and air compressors.
    • 1x 3-Piece Seal/Gasket Set.
    • 1x User Manual
• Pressure Range: Performs optimally at air pressures between 80 psi and 120 psi (600–800 kPa). Pressures below 80 psi reduce clamping force while exceeding 120 psi could damage the unit.
• Clean Air Supply: Requires clean, dust-free air to avoid blockages and maintain peak efficiency. A compressor with a receiver is recommended to ensure a steady, pulse-free air supply.

Handling Small, Irregular, or Large Workpieces:

• Small/Irregular Workpieces: The replaceable rubber seal can be customized or adjusted to fit workpiece grooves for secure clamping of non-uniform shapes.
• Large Workpieces: Support blocks may be needed at the extremities for stability. Multiple VC4 clamps can be used simultaneously to distribute holding force evenly across larger materials.
• Optional CNC Shim Kit: For those materials where you need some extra support or don’t want to risk cutting through your Vac-Clamp Vacuum Clamps, this CNC Shim Kit will protect your investment.

Why CNC Machinists Need It:

• Stability: The bolted mounting system provides a solid, immovable base that ensures reliable clamping during high-precision machining.
• Efficiency: Fast, tool-free clamping adjustments reduce downtime and improve workflow.
• Reliability: With no internal moving parts, the VC4 is built for long-lasting performance with minimal maintenance requirements.
• Flexibility: Customizable seals allow the clamp to adapt to different workpiece sizes and shapes.
