VMC Hydraulic Multiple Clamping Fixture is a custom-engineered hydraulic workholding solution designed to clamp multiple components simultaneously on a Vertical Machining Center (VMC). By using hydraulic cylinders and precision locators, the fixture delivers very high and uniform clamping force, enabling heavier cuts, better accuracy, and shorter cycle times compared to pneumatic systems.
Ideal for mass production, tough materials, and automation-ready CNC environments, this fixture maximizes spindle utilization and ensures part-to-part consistency.
🔑 Key Features
- 💧 Hydraulic Clamping (High & Consistent Force)
