Pneumatic vises

Types of pneumatic vises

The main types of pneumatic vises include lift jacks, split cylinders, tuck jabs, and jaw slides.

• Lift jacks

  A lift jack vice works like a normal jack lift, with a base that remains locked to a work surface. Air control determines whether or not the top element of the lift moves, which is the part that closes in on the object to be held. The control element is also known as the pneumatic cylinder, and it can determine how fast or slow the jack will move up or down.

• Split cylinders

  In this type of jack, there is a left and right part that holds the objects firmly when airpower is on. Unfortunately, hold strength is affected by the natural expansion occurrence of metals, known as thermal expansion. The downside of the split cylinder is that the object's expansion could affect the grip of the vice, thereby making it ineffective.

• Tuck jabs

  This type of vice uses a pocket or tuck to hold onto an object firmly. The pocket is secured to a moving square, which is also known as a jaw. The jaw moves when air control is on, and it moves toward the object to be held. This kind of air vice works excellently on flat materials.

• Jaw slides

  Usually mounted on a linear rail, the jaw moves forward and backward to hold an object. In most cases, the jaw would need to move further back for larger objects, which means more air pressure would be needed to grip the object.

Specification and Maintenance of Pneumatic Vise

The specifications will vary depending on the type of vise and the model chosen. The factors listed here are the main ones to consider when purchasing a pneumatic vise for sale.

• Clamping Strength

  This is the measure of force applied by the jaws of the vise when they are holding an object. It is measured in foot-pounds and is an important aspect to consider because it allows users to hold objects of different sizes with ease. Choosing a pneumatic vise with adjustable clamping strength is ideal because it enables users to work on objects made of different materials.

• Jaws

  The jaws have various features that make them suitable for different objects. For example, the smooth jaw plates prevent marring of the object's surface, while the soft and hard interchangeable jaws are ideal for working with irregularly shaped objects. Another great feature in pneumatic vises is the jaw swivels that allow the jaws to pivot and adjust to different angles.

• Size

  Awordpresshas the size of an object the vise can hold when fully opened. Most pneumatic vises have a standard size of 16 to 24 inches, making them suitable for different projects. Consider the project size when purchasing a vise with a specific size rating. A correctly sized vise can improve work efficiency.

• Control Mechanism

  Aside from the air compressor, the control mechanism brings torque and rotational power to the workpiece. Commonly used control mechanisms include pneumatic motors and pre-set torque control wrenches. Motors with high torque ratings are suitable for heavy-duty applications, while those with less torque are for light and moderate duties.

• Construction Material

  An air compression machine uses metal to build the frame, which affects the overall weight.

Maintenance

Most pneumatic tools require some basic care to function optimally and serve the owner for many years. Here are some basic maintenance tips for a durable tool that aids in metal work.

• Daily Lubrication

  Lubricating moving parts daily keeps them free from dust and debris. Regular cleaning before lubrication keeps the tool in the best condition. The air compressor tool and accessories remain functional for many years with minimal downtime from breakdowns.

• Periodic Oil Change

  Change the lubricant on the vise after a set period, even if the tool works perfectly well. Doing so prevents risk and prolongs the equipment's life. Change the oil based on usage. If the motor runs constantly, change the oil often. However, if running time is less, the oil can stay longer in the machine.

• Storage in a Dry Place

  Always store the tool in a dry, moisture-free place. Moisture in the air can lead to rust and corrosion, reducing lifespan.

Usage scenarios of pneumatic vises

Pneumatic vises have diverse application scenarios in different industries. The following are some usage scenarios of pneumatic vises:
