Vises, Tailstocks and Drivers: Essential Tools for Mechanical Workshops
In the vast world of mechanical workshops, precision and efficiency are decisive factors for the success of any machining operation. In this context, tools such as vices, tailstocks and drivers play a crucial role, ensuring that materials are correctly clamped, centred and supported during mechanical operations.

What are Vices?
Vices are one of the most common and indispensable tools in any machine shop. They are clamping devices that allow a workpiece to be firmly clamped, ensuring that it remains stable during machining operations.

Types of vices
Vices vary greatly depending on their specific use. Among the most common are:

- Precision machine tool vices: used for machining operations requiring the highest accuracy.
- Bench vises: more versatile and used for a wide range of manual operations.
- Hydraulic vices: used in contexts where very high clamping force is required.

Use of Vices in Mechanical Workshops
The main task of professional workshop vices is to ensure that the workpiece is securely clamped, minimising vibration and unwanted movements that could compromise the end result.

The main advantages include:

- Stability during cutting, drilling or milling operations.
- Safety for the operator, who can work without the risk of sudden movements of the workpiece.
- Precision in maintaining the alignment of the workpiece with respect to the machining tools.

Tailstocks: what they are and what they are used for
Tailstocks for mechanical lathes are another crucial element for machine tool workshops. The tailstock is used to support one end of the workpiece during machining, preventing unwanted bending or flexing.

Different Types of Tailstocks
There are different types of tailstock, depending on the type of machining and specific requirements:

- Fixed tailstocks: used for standard operations on workpieces requiring stability without rotary motion.
- Rotary tailstocks: designed for higher speed machining, where the workpiece needs to rotate around its own axis without friction.

Advantages of using tailstocks
The support provided by tailstocks during machining has several advantages, including:

- Prevention of workpiece bending during operations on long axes or materials that require a high degree of precision.
- Improvement of surface finish quality as the workpiece remains centred and stable during rotation.
- The use of tailstock accessories can further improve the efficiency of operations, increasing versatility and adapting the tool to different applications.

Drivers: how they optimise the machining process
Drivers for machining are devices used to synchronise the movement of the workpiece with that of the machine tool spindle, ensuring that the operation is performed with maximum precision.

Operation of Drivers
A drive unit is connected to both the machine spindle and the workpiece. This system allows rotary motion to be transmitted to the workpiece synchronously, ensuring that machining is uniform over the entire surface.

Different types of drive units include:

- Jaw feeders: used in large machining operations, where it is necessary to ensure a firm grip on the workpiece.
- Disc feeders: more suitable for precision machining on smaller workpieces.

Advantages of using pinch rollers
The use of pinch rollers in machining enables the following to be achieved:

- Perfect synchronisation between the workpiece and the movement of the machine, avoiding measuring errors.
- Reduction of defects due to uncontrolled movements, improving overall efficiency.
- Improved workpiece finish, thanks to the precision with which the material is machined.

The correct selection of vices, tailstocks and drivers can make a substantial difference in terms of machining quality and operational efficiency. Although they may seem secondary accessories compared to machine tools, these tools play a critical role in ensuring that each operation is performed correctly.

Frequently asked questions

What is the difference between a fixed tailstock and a rotating tailstock?
A fixed tailstock does not move and is used for low-speed machining, while a rotating tailstock rotates with the workpiece and is used for high-speed operations.

How do I choose the right vice for my workshop?
It depends on the type of machining you do. If you do precision work, opt for a vice for precision machine tools; for more general work, a bench vice is more suitable.

When is it advisable to use a drag chuck?
A drag chuck is essential when uniform machining over the entire surface of the workpiece is required, especially in turning operations.

In a machine shop, the efficiency and quality of the work depends not only on the power of the machines, but also on the choice of auxiliary devices such as vices, tailstocks and drags. These devices, if chosen and used correctly, can increase productivity and improve the end results of machining operations.
