Introduction to Inverted Hydraulic Vises

Inverted hydraulic vises are specialized tools used primarily in machining processes for securely holding workpieces. Unlike standard vises, these vises utilize hydraulic pressure to maintain a firm grip, allowing for more precise and stable operations.

Mechanism of Inverted Hydraulic Vises

An inverted hydraulic vise operates through the use of hydraulic fluid to create pressure within a chamber. This pressure moves a piston, which in turn applies force to the jaws of the vise, securely gripping the workpiece. The design is termed inverted because the hydraulic cylinder is located below the base, creating a lower center of gravity that improves tool stability.

Technical Specifications and Parameters

• Clamping Force: Typically ranges from 1000 to 5000 kgf
• Operating Pressure: 70 to 140 bar
• Jaw Width: 100 mm to 300 mm
• Maximum Opening: 200 mm to 500 mm
• Piston Stroke: 20 mm to 80 mm
• Material: High-strength steel or alloy composites

Advantages of Using Inverted Hydraulic Vises

• Enhanced stability due to a lower center of gravity
• Improved precision in workholding
• Quick clamping and releasing capabilities
• High repeatability and durability

Applications of Inverted Hydraulic Vises

Inverted hydraulic vises are used in various machining applications, including CNC milling, drilling, and grinding. They are particularly useful in high-precision environments where maintaining strict tolerances is critical.
