Types of machine vices

A machine vice, or a machine vise, is used to hold and secure objects in a stationary position to facilitate machining operations. They are typically secured to work tables and are compatible with various types of machines. Workpieces, such as metal pieces, are held tightly between the jaws of a machine vice while cutting, shaping, drilling, or milling takes place. This ensures the precision of the machine and the safety of the operator during the procedure.

Machine vices are available in multiple types to cater to different workpieces and machining needs. The most common machine vice is the machine bench vice, which is secured to tables in workshops and is often used for smaller workpieces. Like other machine vices, it has two jaws—one fixed and another movable—that is adjusted horizontally or vertically according to the shape and size of the workpiece. The bench machine vice also comes in three different styles: the anvil, swivel, and flush mounting.

A specialist in metalworking may use a milling machine vice that is specifically designed for machine mills. Their design allows for precise workpiece adjustments to ensure smooth and accurate milling procedures. One distinguishing factor of a milling machine machine vice is its jaw system. Instead of a traditional horizontal clasp, these vices often have wide jaws that imitate an alligator's mouth and adjust vertically.

Often, workpieces are irregular, so horizontal and vertical jaws won't clamp them properly. The best solution in such cases is to use a machine vice with a sliding jaw. Also known as a machinist's vice, it features one stationary jaw and one movable jaw that slides on a parallel track. Its design allows it to hold irregularly shaped workpieces.

Machine vices come with or without jaw openings. The former has slots on the jaws to grip irregularly shaped workpieces, while the latter is flat and usually features larger jaw openings. Another way to categorize machine vices is according to jaw alignment. Some vices have jaws that align parallel to the slide movement, while others have jaws that are perpendicular to the slide movements. The alignment type usually affects the clamping action of the moving jaw.

A question often asked by buyers is whether to get an automatic or manual machine vice. Manual machine vices are operated by hand. Therefore, adjustability and operability are limited. Nonetheless, they allow workmen to work at their desired pace. On the other hand, automatic machine vices increase productivity and efficiency by speeding up the work process. However, they are usually pricier than their manual counterparts.

Specification and maintenance of machine vice

Specification

• Capacity:

  The biggest size or weight that a vice can hold is known as its capacity. Larger goods may be clamped thanks to greater capacities.

• Clamping Force:

  Clamping force refers to the amount of pressure a machine vice applies to hold an object securely. It is measured in Newton (N) or Pounds (lbs). Higher clamping forces provide a stronger grip, suitable for heavy-duty applications. Choosing a vice with an appropriate clamping force ensures proper workpiece handling and prevents damage.

• Jaw Width and Depth:

  The jaw width is the measure between the two jaw plate edges, while the jaw depth is how thick the jaw plates are. Vice with broad and deep jaws can accommodate larger and irregularly shaped things, distributing clamping pressure evenly.

• Material:

  Machine vices are usually made of cast iron or steel. Cast iron provides good stability, vibration dampening, and strength. Nevertheless, it may be brittle and less impact-resistant. On the other hand, steel is typically stronger and more impact-resistant since it is more flexible.

• Accuracy and Repeatability:

  A workpiece's positioning precision when clamped and the consistency of its recurring alignment are referred to as accuracy and repeatability. Machine tasks depend heavily on accuracy and repeatability to produce exact results. It is essential to pick a vice whose straightness, roundness, and flatness tolerances are high so that workpieces may be aligned appropriately, ensuring little margin for error during machining operations.

Maintenance

• Clean:

  The best method to keep the machine vise in good conditions is to clean it frequently. Wipe off any foreign items after removing the part. To clean all of the surfaces and joints of the clamps thoroughly, use an air gun and blow-off residual lubricant, cooling liquid, and chips. To remove any rust or dirt, apply a wire brush to the clamp jaws. Use an oiled cloth to clean the surfaces after that to stop rust from developing in the future.

• Lubrication:

  Lubrication is required after cleaning the machine vice to maintain its mobility and lengthen its lifespan. To remove any dirt and rust from the cleaned sections, dip the oiled rag in oil and wipe it down. Apply oil to the threaded portion of the screw, the sliding surfaces, and the guide rails. Lubrication should be done on a regular basis to ensure proper movement and extend the life of the machine vise.

Uses of a machine vice

A machine vice is commonly used in metalworking and woodworking industries, but that is just a small fraction of its many applications. Here are some common use scenarios for a bench vice.
