Vices

Vices hold workpieces in place while they are being machined. They typically consist of a mechanical device consisting of two jaws, one of which is fixed and the other movable. The movable jaw is pressed against the workpiece by a screw or spindle to hold it securely in place.

Vices are used in many different areas. They are standard equipment in workshops and are used to hold workpieces in place during drilling, cutting, grinding or filing work. In industrial manufacturing processes, they are used to hold workpieces while they are being processed by machines. In wood and metal processing, vises are used to hold materials securely in place during cutting, milling or grinding. In electronics production, they help to stabilize circuit boards or small electronic components during assembly or soldering. During assembly work, vices make it easier to hold and manipulate components. Hobby craftsmen and DIY enthusiasts use vices for a wide variety of projects, such as model making, repairs and the production of DIY constructions.

What types of vices are there?

There are different types of vises, each designed for specific applications and requirements:

Machine Vise
A machine vise is a tool used in metalworking and other precision machining processes to securely hold workpieces during machining. It is mainly used on milling machines, drill presses, and grinding machines. The machine vise is made of durable materials such as cast iron or steel and has precisely adjustable jaws that firmly secure the workpiece. Depending on the model, the jaws may be operated manually or hydraulically. A machine vise ensures high repeatability and stability, which is essential for precision machining.

Pipe Vise
A pipe vise is a specialized type of vise designed to securely hold and clamp pipes and cylindrical workpieces. It is commonly used in plumbing and pipeline work. The pipe vise features specially shaped jaws that wrap around the pipe's curvature, holding it securely without causing damage. These jaws are often equipped with non-slip surfaces to prevent the pipe from slipping. Pipe vises are typically made of cast iron or steel to withstand high loads.

Drill Press Vise
A drill press vise holds workpieces firmly and securely while they are being drilled or machined. It is commonly used in conjunction with a drill press and provides a stable and precise clamping solution to enhance accuracy and safety during drilling. The vise is typically made of robust materials such as steel or cast iron and has adjustable jaws to secure the workpiece.

Zero-Point Clamping System
A zero-point clamping system is a high-precision clamping solution used in manufacturing and machining. It allows for quick and repeatable positioning of workpieces or fixtures on machines and fixture systems. This system typically uses spherical clamping modules and zero-point clamping pins, which are anchored in precise bores or holders. The main advantages of a zero-point clamping system include drastically reduced setup times, increased machine uptime, and improved precision and repeatability in machining.

Are there accessories for vices?

There are a variety of accessories that can be used with vises to enhance their functionality and adapt them to specific needs. Here are some of the most common vise accessories:

• Protective jaws: Replaceable jaws made of softer materials such as rubber, plastic, or aluminum to protect delicate workpieces and prevent scratches. They can be replaced periodically due to wear.
• Rotating base: A base that allows the vise to rotate, enabling work on the piece from different angles without repositioning it.
• Clamping jaws: Additional clamping devices attached to the vise jaws to improve grip on special-shaped workpieces.
• Clamping fixtures: Additional attachments mounted on the vise to increase holding force and secure complex workpieces.
• Workpiece stops: Adjustable stops attached to the vise to quickly and precisely position workpieces, facilitating repeat machining.
• Magnetic jaws: Jaws with a magnetic surface that make it easier to clamp metallic workpieces and provide extra holding force.
• Centering jaws: Special jaws designed to precisely align and center round workpieces.

What should I bear in mind when using vices?

When using vises, it is important to follow some key guidelines to ensure safety, functionality, and longevity:

• Proper mounting: Ensure that the vise is securely attached to the workbench or machine to prevent shifting during use.
• Correct workpiece clamping: The workpiece should be firmly and evenly secured between the vise jaws. Avoid clamping at an angle to prevent damage and inaccuracies.
• Use appropriate jaws: If necessary, use protective jaws made of softer materials (rubber, plastic, aluminum) to prevent scratches and damage to delicate workpieces.
• Avoid overloading: Do not overtighten the vise to prevent damage to the spindle and jaws.
• Regular maintenance: Clean and lubricate the spindle and guides regularly to ensure smooth operation and reduce wear.
• Safety precautions: Wear appropriate protective gear, such as gloves and safety glasses, especially when working with materials that produce chips or splinters. Ensure that no body parts or loose clothing get caught in the vise jaws.
• Use the right size: Select a vise that is large enough to hold the workpiece securely but not so large that it becomes difficult to handle.
• Proper application: Use specialized vises for specific tasks (e.g., pipe vise for plumbing work) to ensure optimal results and safety.
