Both vise and chuck are fixing devices used in metal processing. In the metal processing industry, a vise is a mechanical device used to fix the position of a work piece for processing. The vise has two parallel jaws, one is fixed and the other is movable, screwed in and out by screws and levers. Although woodworking also uses vises, in this article we only discuss vises for metalworking.

Mounting and installation

Mechanical vises are mostly installed on machining centers, drilling machines, grinding machines and milling machines. In lathes, chucks and cylinders are standard components used for similar purposes. The abrasive chop saw has a built-in vise. In addition, there are a variety of magnetic vises, their purpose is to fix the work piece to ensure the completion of processing tasks.

Magnetic and hydraulic chucks are the most important components in the machining process of machine tools, for work piece clamping and fixing. Magnetic chucks for machine tools have a huge market in the industry, and account for a large share of Taiwan's exports, not less than the number of machine tools, and contribute a lot of income to Taiwan's economy.

The list of machine tool components is very extensive, such as casted parts, spindles, motors, servo equipment, saddle, locknut, shells, hydraulic cylinders, magnetic chucks, claw, precision screws, tailstock, tools and holders, power turret, chip conveyor, belt unit, safety cover, controller, handle, display screen, etc.

The chuck holds the work piece to be cut in place. Depending on the material of the work piece, chucks can be divided into two categories. The first is to fix the ferro-magnetic pieces in place by magnetic chucks, and the second is to fix the non-ferro-magnetic pieces or non-metal pieces in place by vacuum or mechanical methods. If the machine is equipped with only magnetic chucks, you can use the mechanical vises placed on the chucks to hold non-ferro-magnetic pieces. In surface grinding applications, the deciding factor of the chuck type also includes the material of the grinding wheel.


Chuck & cylinders

In a cylinder-driven chuck mechanism, users may find similarities between the two. Taiwan's spindle and chuck and corresponding hydraulic cylinders are highly developed. In the CNC lathe market, a variety of lathe products and accessories are widely used around the world. Among them, the CNC horizontal lathe is a conventional design, which has been developed and widely used for more than 100 years.

The structural characteristics of the horizontal lathe make it easy to use and maintain, so it is widely used in many industries. For lathe users, the horizontal or vertical structure does not have absolute advantages and disadvantages, but depends on the machine application and work piece type. On the other hand, twin spindle lathes are not so common, but when considering a lathe equipped with a turret, the twin spindle lathe needs to be mentioned. According to the way of clamping the work piece, they are divided into two types: vertical lathe and horizontal lathe.

What is a clamping system? The clamping system and the power turret are two related machine accessories. In the vertical clamping mechanism, the spindle is located behind the chuck. The spindle may be driven by belt or other types.

Like milling machines and machining centers, lathes can also be equipped with power tools and tool magazines to improve their functionality and versatility. Power turret is a modern accessory of many CNC lathes. On the other hand, the machine equipping twin spindle can greatly improve the machining area and productivity, which will bring huge production efficiency for business owners.


Future Trend

Combined with automation, the twin spindle turning center is a very efficient machine in the production line. Due to many practical problems such as lack of manpower, raising wages, environmental protection, raising the requirements of professional standards, etc., automation is the future trend of all manufacturing plants in the world. At present, factory owners must deal with stricter standards than before and keep up with the latest manufacturing trends, prompting many business operators to build automated factories. But automation still depends on the improvement of corresponding technology.
