Vise machine: features, characteristics, types and

A Vise called a universal fixture designed to hold the workpieces in the course manual (in this case, a vise mounted on bench bench) or mechanical (using special machine vise) processing.

Machine Manufacturers offer a wide selection of clutches of different types. Each has certain characteristics and has a number of features. Thus, based on the characteristics of the technological process and equipment, it can be concluded that the selection of clutches is quite a difficult task. How to make the right and optimal choice taking into account the existing Park of machine tools? The article provides an answer to this and other questions that may arise when planning and purchasing equipment for their own workshop.

What materials are made clutches

The grip is executed from steel or gray cast iron. Most often there is a cast housing. This is because cast iron has very good casting qualities (melt freezes for quite a long time and manages to fill the mold) and a lot cheaper steel. While the mechanical properties of the alloy with a high content completely satisfy the requirements for materials used for the manufacture of both manual and machine Vice.

The Market was flooded with equipment from China, Europe and America. In these countries developed and used their own standards. As for the Russian Federation, its territory, the production of such equipment is strictly regulated by GOST 16518-96.

The most Important technical characteristics grip

When choosing a specific fixture, you must read its technical parameters and capabilities. First of all, not to throw away money, you need to find out to install on which machines they are intended (milling, surface grinding, planing, broaching, drilling or other machines).

Then you need to check whether the width of the working jaws are sufficient or too narrow and will take great effort to put pressure on the surface of the workpiece, leaving dents in it. Another important factor is the clamping force. Stroke length allows to determine the maximum linear dimensions of the installed in the grip of the workpiece.

In that case, if the clutches are purchased for a hobby machine small size, installed in a garage or in the basement of an apartment building, and even on the balcony (there is!), it is critical, of course, is their weight. The limit on the weight of the product installed on a small workbench for hobby, not to exceed, as mechanical components in such a machine will fail.

Types and varieties of Vice for metal working

• In accordance with the specified standard commercially available vise normal precision, high accuracy and high precision, are equipped with manual or automatic (hydraulic, pneumatic, electric) drive.
• Depending on destination are divided into manual vise, bench, machine, special (with automatic drive).
• Type of drive distinguish machine vise with manual clamp, hydraulic-actuated, with detent (or eccentric clamp), spring clamp.
• Depending on the workpiece material and its mechanical properties in a vise can be mounted sponge of different hardness and with different notch.

Basic elements the grip

Modern machine vise structurally significantly different from the classical grip. However, the principle of work and actions has remained unchanged, and it is possible to allocate following basic components: a housing, movable and fixed jaw, arm, power trapezoidal screw with thrust thread handle.

Features vise mounted on the table of a milling machine

Milling Machine vise there are, perhaps, in every workplace. And if in the conditions of mass production tend to make a special fixture to mount on the desktop of the blanks in terms of unit production, and repair production, not to mention garage workshop, such vices are simply irreplaceable thing.

For the clutches to be installed on the machine, rigidity is critical and the most important parameter. If the design does not provide the rigidity, in the course of treatment will be unpleasant and annoying hearing a loud screech of metal. The mill will rattle. As a result – premature failure of very expensive tool and poor surface roughness of the treated surface. Sometimes detail can even go into marriage, which means more financial losses.

If universal plumbing grip sponges have a distinctive grooved surface on the vise for a machine they should always be smooth. And not allowed rough untreated smooth surface after casting. These sponges are processed by the cutting tool (cutter or cutter), and then polished on surface grinding machine to achieve the desired indicators of roughness and geometric shape.

Swivel machine vise

These clutches are mounted on a rotary mechanism. He has no restrictions and can be rotated to any arbitrary angle. To rotate you must loosen the two nuts at the base. Once exposed to the right angle, the nuts are clamped in a certain position with open end wrench with great effort.

The Disadvantage of such clutches is the lack of rigidity. But the rotation plate can be removed, and then it will be a regular fixture.

Machine vise for drilling machines

A Vise mounted on the base frame vertical drilling machine should ensure the possibility of displacement of the workpiece in two directions in the horizontal plane. This statement is not true for radial drilling machines, as they moved the spindle installed in it by a drill. In General, the machine vise for drilling units have much less rigidity compared to milling, as they have many degrees of freedom.
