High precision vises

Types of High Precision Vises

High precision vises are used in various industries to hold workpieces securely during machining operations, assembly, and inspection. There are several types available, each designed for a specific application and workpiece.

• Heavy-Duty High Precision Vise

  A heavy-duty high precision vise is a type that is built to withstand extreme use and hold heavy workpieces securely. It has a solid cast iron body with reinforced stress points and large capacity jaws. The jaw faces can accommodate larger workpieces and are compatible with various jaw face materials. Despite its massive build, a heavy-duty precision bench vise is a high-quality product that offers fine control. It is usually mounted on a workbench or stationary surface using bolt-down holes or flange surfaces. A heavy-duty precision machine vise, on the other hand, is typically mounted on a milling machine or machining table with T-slots.

• Universal High Precision Vise

  A universal high-precision vise is designed for clamping workpieces of different shapes. It is used as a bench vise or machine vise and features jaw plates that can be interconnected to fit irregularly-shaped workpieces. Additionally, the body of a universal vise can be swiveled in any direction and tilted on its horizontal axis and vertical axis relative to the machine's cutting tool. Therefore, a universal machine vise must not be limited to rectangular and cylindrical workpieces. It is a fantastic tool for metal fabrication workshops that often work with various shapes. Besides the standard control levers, a universal high-precision machine vise may also feature control knobs, clamping studs, and mounting holes for easier workpiece clamping.

• Precision High Vise

  The distinction between heavy-duty and standard precision vises lies primarily in their jaw capacities. A standard precision vise has adequate jaw capacity to hold average workpieces tightly. Just like a heavy-duty precision vise, it features a solid cast iron body and finely machined jaws for maximum gripping power. An ordinary high-precision bench vise provides reliable service and reasonable performance specifications under normal use.

• Low Profile High-precision Vise

  Also referred to as short high-precision vises, low-profile vises are more compact and easier to access than regular high-precision vises. These vises are stable and allow effortless workpiece clamping. On the other hand, the jaw capacity may be limited. Low-profile precision machine vises are ideal for use in machining applications where accessibility and stability are paramount. They are used to machine parts with low profiles or to access tight spaces and contours. Moreover, they are great for improving the operator's sightlines.

Specifications and maintenance of high precision vises

Specifications

High precision vises' specifications can vary according to the models and types.

• Material: The high precision vise body is usually made of ductile iron or iron, and the jaw is of steel or hardened steel. Ductile iron is favored for its combination of strength and impact resistance. This allows for secure workpiece retention, even during high-intensity operations. Steel, known for its superior strength and durability, ideally provides stability. Moreover, it's able to withstand regular use without succumbing to wear and deformation. Hardening processes not only enhance toughness but also ensure maintained precision over time. Many high-precision vises incorporate a cast iron or aluminum brake. Cast iron, with its excellent dimensional stability and resistance to deformation, ensures that the brake remains precisely where it's positioned. This prevents sudden movements of workpieces during machining, especially during milling, that may lead to accidents or damage.
• Jaw width and height: Jaw width and height determine workpiece accommodation. The parameter is usually represented in millimeters, such as 75*45, 100*50, and 125*63.
• Clamping range: The clamping range is a scope that specifies how wide and thick workpieces can be held. It is usually around 0–14 mm, depending on different types of high-precision vises.
• Net weight: It is a weight of the precision vises themselves, which is usually between 6.7 kg and 29 kg.

Maintenance

Regular maintenance can help high precision vises to prolong service life and keep in good condition. Here are some tips for maintaining precision vises:

• Regular cleaning: Cleaning the vises is the first step in maintaining them. Regularly wiping dust, shavings, and dirt off the vises can prevent debris from accumulating and affecting their precision and smoothness. In addition, it is vital to pay attention to cleaning the internal parts, such as screw rods and guide rails, to avoid the accumulation of dirt.
• Lubrication: Lubrication is critical to ensuring smooth operation and prolonging service life. Use the right lubricants and apply them to the screw, guide rail, and other moving parts.
• Rust prevention: Rust is one of the main enemies of precision vises. Use rust-proof oil or spray to prevent it, especially in humid environments.
• Use and storage: Avoid excessive force when using precision vises and ensure that clamped objects are within their applicable ranges to prevent damage. When storing, choose a dry and airy place and avoid direct sunlight or damp environments.
