In essence, any device intended for accurate and fine works in a workshop with various parts and blanks can be used complete with machine vibrations.

At the same Tire versions are not always present in the package when purchased, although their presence is not very affected by the value of the model in general. Sometimes Machine vice in the case of a wizard kit is also called checked for the convenience of designation specifics.

But the use of vice depends largely on the materials that will have to work in the future. For example, for wood or plastic they do not need. To fix the item on the spot, it takes a minimum of effort. And in the case of plastic, excessive pressure may even deform the material.

Visks are needed when working with steel, cast iron or any other heavy metals. Their presence in the kit will allow not only to effectively fulfill the task, but also to comply with all security requirements.

Design device

There are a number of major elements at the heart of any machine tools:

  • steel strips at the base of vice;
  • Mobile and stationary sponges that directly clamp and hold the workpiece during operation;
  • a knob with a screw to control the entire design changing the position of the sponges;
  • Additional plates and fasteners, ensuring the integrity and reliability of vice in the process of work.

With the help of basic Plank All other details of the vice are recorded. This is a kind of foundation, providing the work of vice throughout the operational period. Therefore, it is chosen hard and durable metal. In the specified place Burned hole Under the screw for the future fastening of sponges. At the movable sponge below Install a small steel plate – This makes it possible to fix their movement and reliably protects from the scraping from the grooves.

Another detail worth paying attention is screw. It connects with a sponge with a small steel ring by rotating in a specially done threaded hole in one of the main planks.

The sponge moves, thereby ensuring the clamp between the movable and fixed parts. But the screw action in different models may differ – it all depends on the features of the selected design. Simple models combine the screw and movable sponge directly. The clamp is provided by either due to the fact that the screw pulls the sponge behind it, or repels in the process of movement. The concept will differ depending on which side of the screw rotates.

Concerning Rotary models, That to facilitate the work, the energy for the screw is supplied by several gears interconnected in several lines. In this case, the master does not need to apply too much effort while treating heavy and massive blanks. This is only one of the examples of a more complex design.

Views

Machine vice can be divided into several types.

Non-referential vice Also called stationary. Their design is most simple in order to make their homes. The vice themselves are fixed in the same position on the working surface of the machine.

Only one hole is made in such models. In order to change the position of the workpiece, moving either themselves via the working surface, or sponges are squeezed, and the part is pulled out. The design itself is rigid, does not imply small, cosmetic operations, in contrast to turning models. For the price they are located in the category below average and therefore available to almost everyone.

Models with a swivel mechanism are more expensive than the rest, they are more effective for processing parts at an angle, there are also universal vice, which include all the advantages of swivel and non-refining structures.

But they have a higher cost, so do not always fit for a home workshop.

Rotary vice allow you to work throughout the coordinate plane without removing the blank from the clamp and without changing the position of the tool itself. The difference from previous models is that there is a special turntable up to 360 degrees around the circle, so the item can be deployed literally at any angle for subsequent processing.

Visits globe type make it possible to work in three planes immediately at the expense of a special platform, thanks to which you can reproduce even inclined holes. The most important thing in the process is to choose the right corner. Working with the detail with this tool will be painstaking and long-term.

Sinuous quick-swing vice – auxiliary tool for machine tools of various types, with which you can perform a series of operations ranging from milling and ending with planing or grinding. As a rule, they are actively used in fitter work when processing the workpiece at an angle to the vertical. The processing angle is usually sharp, it all depends on its size and complexity of the task set before the master.

Three-axis machining vice Installed on milling and trusted machines as an additional equipment element. The material of the manufacture serves the cast iron, the design includes a rotary platform and a number of additional small parts that significantly increase the accuracy of working with any materials. The total weight of the tool is from 4 kg, the climbing zone is quite wide, so that the Master has the opportunity to work with overall billets.

There are more complex models with a pneumatic. Such Hydraulic reinforced vice Installed on milling machines as the main tool for processing. Material for manufacture serves cast iron or any other metal, similar to technical specifications and resistance level by mechanical damage, corrosion and other breakdowns during operation. When the part of the part it turns out a certain proportion of pressure on it.

You can work in several ranges, if necessary, moving the locking pin.

Pneumatic vice often additionally equipped with hydraulic amplification. With their help, you can work with heavy metal blanks without risk to spoil the product. Cabinet and fasteners are made of steel and cast iron, sponges have a wide moving course – up to 250 mm inclusive. You can install vice on any horizontal surface with special fasteners. In the clamping mechanism there are several springs, which additionally enhances the indicator of its reliability and safety under pressure during operation.

Criterias of choice

In the process of choosing the design of suitable vigors, a number of parameters are taken into account:

  • Functional application of the model;
  • Features of the fastening mechanism;
  • Production material of sponges and other major parts;
  • sizes of sponges and their maximum move;
  • the level of pressure on the workpiece during the processing process;
  • maximum and minimum during the screw;
  • Weight and weight of vice (if a desktop assembly is planned, the size of the future work surface is also taken into account);
  • Drive mechanism.

If we talk about the benefits of vice, then first of all it is worth remembering the possibility of working with overall and heavy blanks.

Steel and cast iron As basic materials guarantee high wear resistance and corrosion protection. You can perform thin and accurate work without fears. To spoil the item.

Manufacturing at home

Machine vice – a tool designed to work with hard material, so for the reliability of their main and most important parts in the designs are made of durable steel or cast iron. The designs themselves may differ from different models depending on the type and profile of the use. If the wizard first manufactures the vice with their own hands, It is best to choose non-reflective vice to dial the necessary experience and skills.

The only complexity in the reproduction of some vice at home is the features of the design of rotary and non-reflective models.

How to install?

Machine vice, like self-made, can be attached to the table using special bolts, which are in special notches at the base plate. If the design is made manually, you can come up with another, more comfortable type of fasteners. The grooves are fixed perpendicular to one to the other on the surface of the table or machine, the base of the vice is wiped before that. And also for fixation there are several steel plates. If the vice is fixed across, these plates are also inserted into transverse grooves. The use of bolts and fastening nuts is required to comply with technical safety requirements.
