Table vices from China have a stranglehold
It is difficult to imagine a country cottage without a garage. In this holy place, the master often takes his soul away, repairing all kinds of mechanisms. Without a desktop vice, it will be difficult to quickly and efficiently perform such work. Chinese manufacturers offer to buy surprisingly high-quality goods from them.
With the help of a simple device, a locksmith can easily fix parts, as well as special blanks. Indeed, only in a stationary position the structure lends itself to the required processing.
General characteristics
The tool is made of high carbon steel - cast iron. There are no soft elements in its design. The material easily withstands dynamic loads and high temperatures (up to 450 ° C), while not losing its properties. Also, it is not subject to corrosive effects, which significantly increases its wear resistance. Despite its significant weight (1.55 kg), it is a pleasure to work with it. Among other things, the vise has useful characteristics:
- Fastening mechanism. The capture width is 50 mm. Install the device on tables, stands, as well as workbenches, tightening the screws tightly. The coefficient of adhesion to the surface is high because the clamps are cup-shaped.
- Static and movable jaws. They are made of hardened steel. The opening range of the plates varies from 0.5 to 65 mm. There is a slight backlash in the connected state, but for rough work with large parts this is not a problem.
- Rotary device. The device rotates around its axis. So, parts can be processed at different angles.
- The presence of an anvil. It is used to trim the workpiece with a hammer. The advantage of a cast iron vice is that it can withstand a series of strong impacts without deforming.
The retractable handles of the fastening device allow easy control of their movement. Each screw has a clearly made thread, so it can be screwed in quite easily and quickly.
You can not be silent about the shortcomings
The compact, and most importantly stable, device is not without its drawbacks. In addition to the play between the jaws, the weak point of the vice is in the lock washers. They wear out too quickly, which is why they need to be replaced frequently.
The width of the plates in such tabletop instruments is relatively small. For this reason, they do not hold well long workpieces, the other edge of which often outweighs the center of gravity. At the same time, with strong and prolonged impacts, the device goes off its axis. So, it has to be constantly corrected.
On the Aliexpress site, they offer to buy a table vise made of cast iron (made in China) for only 1,034 rubles. Domestic online stores ask for the same model up to 1,200 rubles. and more.
