Of 6 kinds of clutches best: how to choose the pros and cons, features

vise intended for fixing the workpiece. On how the workpiece is secured, the final result depends. By choosing a tool is required to approach thoroughly weigh all the "pros" and "cons."

How to choose a vice

The quality of the workpiece depends on:

• instrument;
• the skill of the performer;
• device, wherein the workpiece is fixed.

Important parameters:

What to look for:

• Functionality. Vices correspond to the operation. Metal products are fixed in metalwork models. Wooden blanks - in joinery.
• dimensions. This characteristic determines the dimensions of the workpiece. With the increase in mass increases the design dimensions. For stationary tool is not as important with portable weight constrains.
• Material. Purpose design - reliable fixation of goods. Emitted wherein forces act on the preform elements and clutches, however for the manufacture of durable materials are used.

• Fixing to the base. When machining a workpiece fixture can move. To avoid this, in the design of a mechanism fixed to the ground.
• rotatable. In working with the workpiece is often a need to change the position of the processing from a different angle. For this main body is rotated about a vertical or horizontal axis.
• Changing fixing elements. The workpiece is clamped in a vice through the cheek. To secure grip cheeks surface relief is performed. But this can lead to deformation of the material. To avoid negative consequences, cheeks make interchangeable.

Native elements are made in the form of rectangular flat plates. They are easy to use when working with flat surfaces. But curved to fix the product difficult.

Increasing efforts at consolidating leads to deformation of the part. It uses replaceable prismatic devices.

• Build quality. Estimated by appearance during operation. There should be no distortions. The form has a finished look. Straight line, and if curved, the presence of a smooth transition.

Burrs are unacceptable, sharp edges are dulled. Backlash in the compounds no. Threaded pairs are covered with grease. Rubbing each other on the surface subjected to fine grinding. The movement of adjacent parts smoothly without jamming.

• Warranty period. It indicates the quality of manufactured products. No manufacturer warranty for workmanship in the product.
• cost of. Determining factor in the purchase decision. It added to the consideration of the above information. The price effect "untwisted" trademark.

Specialists who regularly use opportunities clutches, there may be additional criteria for the selection of devices. But for most consumers these data sufficient to determine the necessary tool.

Secondary parameters:

In addition to the basic indicators, there are a number of characteristics that do not affect performance.

• color. It performs a decorative and protective function. Therefore, the background color will not affect the work of the device.
• grease. The abundance of lubricant which are covered vise, - a layer which protects the construction from rusting during transportation or storage. This is typical of domestic production.
• Ease of application. Devices of the same type are similar to each other.
• Packaging. The task - to carry the information function and ensure easy transportation of the goods. External registration will not affect the product properties.
• brand name. Trademark carries the information for the professional. For most consumers, a highly specialized product brand label fades into the background. Importantly - the country of origin.
