Precision Vise

Precision Vise Details

Precision Vises are highly accurate and reliable workholding tools used primarily in CNC machining, toolmaking, and metalworking tasks that demand exact positioning and secure clamping. They are designed to hold workpieces with minimal deflection, ensuring that even under high-pressure machining operations, the workpiece remains stable and precisely aligned. These vises are ideal for tasks that require high precision, such as grinding, milling, inspection, and assembly operations.

Key Components

Clamping Jaws: The jaws hold the workpiece securely in place. In precision vises, these jaws are usually ground to a very high level of flatness to ensure even clamping force and minimal distortion.

Base: The robust and stable foundation of the vise that can be mounted on machine tables or inspection tables. Precision vises often have a hardened and ground base to ensure accuracy and stability.

Lead Screw or Spindle: The lead screw or spindle is responsible for moving the jaws together or apart, applying uniform pressure to the workpiece. Precision vises often use fine-pitched screws for smoother operation and more controlled tightening.

Fixed Jaw and Movable Jaw: The fixed jaw remains stationary while the movable jaw is adjusted to clamp the workpiece. Both jaws are typically ground to precise tolerances for accuracy.

Angular Adjustment (Optional): Some precision vises feature adjustable bases or tilting mechanisms to allow angular positioning of the workpiece for complex machining tasks.

Advantages

High Accuracy: Precision vises are engineered to provide extremely accurate clamping, with tolerances often within microns. This accuracy ensures that workpieces are held securely and precisely aligned during machining.

Minimal Deflection: Due to their robust construction and precise engineering, precision vises minimize deflection even under high cutting forces, ensuring consistent results across multiple operations.

Smooth Operation: Precision vises feature fine-pitched lead screws or spindles, allowing for smooth and controlled adjustment of the clamping jaws, which reduces the risk of over-tightening or damaging delicate workpieces.

Durability: These vises are often made from hardened steel or other wear-resistant materials, ensuring long-lasting performance even under demanding conditions.

Versatility: With various types of precision vises available, such as tilting or multi-axis models, these vises can handle a wide range of tasks, from simple clamping to complex multi-angle machining.
