Any technique verses a person knows how important visks for a drilling machine. First of all, they are needed for reliable fixation of the details – without this it is impossible to carefully and accurately drove the cavity. The modern market is rich in all sorts of modifications of vice, and each model has its own characteristics and scope.
The main feature of all vice – Easy to use and non-hard design.
With a great desire, many models can be made independently, but there are such that it is better to buy, for example, vice cross.
The modern market offers a large number of different models that are complemented various functions and devices.
However, the basic model of the vice includes:
- The base of the vice, which should be quite strong, therefore it is most often made of high-strength steel or thick cast iron;
- a fixed sponge (bed), welded to the base;
- a movable sponge connected to the running screw;
- Screw with a lever that moves a movable sponge, providing fixation of the part;
- Pads that are attached to the sponges and can have various forms.
Visits for the fitter’s table are divided into two main types: Rotary and non-referential.
Rotary (or coordinate) can rotate 360 degrees. The design allows you to drill a few holes without getting a piece of sponges. Crusades, equipped with crosses, and allowing the movement of the product at an angle and with a longitudinal, and with a transverse feed, called Two-coordinate.
Another type of vice – global (sine) or three-way – works with a detail in three axes, which allows drilling holes at various angles for a much smaller hours of work.
In the market of equipment among swivel double-chiced tees, have proven themselves perfectly Chinese vice kobalt 246-012. Owners celebrate high quality, fixation without product deformation. The disadvantage is an uncomfortable handle.
Novelty among cross-nosed coordinate vice – Tool BG 6368 3 “/ 75. This model perfectly claps cylindrical parts due to a special two-axis groove, has screws for the backlats (in the number of three pieces) and high quality. However, small disadvantages are small dimensions.
Non-reflective visks are otherwise called stationary. Look like a base with welded sponges and handle. Fix the item strictly in one position. Non-reflective visks can be easily done independently. The most common type of non-reflective vice – machine. Things are attached to the machine bolts that are included in special T-shaped slots.
Some of the best stationary vice is the brand tool Sparta 186255. Owners celebrate compactness of dimensions, impressive force of the clamp, strengthening in places subject to deformation. The base of the cast iron has one flaw – With a strong tightening of the bolts of the eye can be deformed.
“Enkor 100” of Russian production – Machine crossing vice. Strong design, comfortable handles and hardened sponges. From disadvantages – non-primary species.
How to choose?
To begin with, decide which Sponge breeding width Maybe you need – it will depend on it, which thickness of the part can be fixed by visk. Then it is necessary to decide, vice will be Removable or fastened to a locksmith table forever and ever. For non-removable equipment, a significant mass will be a plus, and for removable it is necessary to take into account your physique and the availability of the place where they will be stored. Many tasks are solved by a removable tool weighing 8-10 kilograms with a width of sponges in 100 millimeters.
Be sure to check the quality of the vice prior to purchase: the sponges must be moved softly, without jerks and jams. High-quality tool at the end of the running screw is a fuse in the form of a nut or washers – it is necessary to prevent full sponge outlet from the bed.
All broadening at the ends of the turn is needed a large diameter to eliminate the screw.
When compressing sponges, the lining must be close to each other, Maximum allowable discrepancy – 0.5 mm. It is checked. It is quite easy – we hold the thin metal rod on one edge of the sponges, and measure the width of the sponges, then the same rod clamp on the other edge, and also measure distance. The difference between these numbers should not exceed the maximum allowable 0.5 mm.
You can check the quality of the linings themselves like this: remove the lining from the sponges and install them on the contrary, the adjacent planes should also match.
Sponges strictly parallel to each other, movable – does not walk around. Thoroughly Inspect the face for cracks, Feel free to knock on it. The chassis must be thick – this indicates his strength stock. With high quality processing on the surface of the screw is shine. Inspect the screw for burrs and jackets on it, you can even touch your fingers in doubt. If they are, the quality of the instrument leaves much to be desired, or they have already enjoyed them. Weakening the side screws, see if the rotating part will rotate.
Quality tool can not be cheap, But during the operation, you will not regret the money, because such equipment serves a very long time and may well move away from you to the inheritance for children.
Sometimes found Remains of the Earth from the shape or rust on the bottom In places adjoining the foundation and stationary sponge. It is removed by a brush for metal, a file.
It is impossible to remove the use of any abrasives, since particles of such materials can settle on the move screw or the nut, thus accelerating their wear.
Many masters, minimizing the working noise, often stick to the bottom of the basics of a rubber gasket, or screw the equipment to the workbench. It is not necessary to do if you do not use them all the time, but for constant work, the Council, indeed, useful.
It is possible to discuss what vice is better, and which models will be more useful to perform certain tasks, but first of all You need to focus on your needs and opportunities. Almost all the vice can Make yourself Based on its requests, but you can spend time in life, but buy a good tool.
