The precision milling vice is an essential tool for those who work in the mechanical milling sector. This type of vice, especially when revolving, allows you to secure the workpiece safely and precisely, ensuring stability during the milling process.
Visually, the precision swivel vise looks like a sturdy block of metal, usually made of cast iron or hardened steel. The base is solid and heavy to ensure excellent stability, while the upper part is made up of two parallel jaws which, once tightened, hold the piece in place. The feature that distinguishes it is the 90 degree rotation both to the right and to the left, making this vice particularly versatile in angled milling operations. The rotation system is equipped with a locking mechanism that allows you to fix the vice in the desired position.
The precision vice in question has a maximum opening of 200 mm , while the width of the jaws is 160 mm . These dimensions are ideal for processing medium-sized workpieces, allowing for secure and stable clamping. The ability to rotate 90 degrees left and right makes this vise extremely flexible, allowing you to work from different angles without having to reposition the workpiece.
The clamping mechanism is generally operated via a fine pitch screw which allows the jaws to be gradually and precisely tightened around the workpiece. The jaws themselves are often made of hardened steel to resist wear and ensure long life. The smooth movement of the rotation and clamping mechanism is essential to ensure precision, a crucial aspect in milling.
Using the precision swivel vise is relatively simple, but requires attention to ensure quality results. First of all, place the vice on the router table, making sure that it is well fixed with bolts. Once installed, you place the piece between the jaws and tighten it using the clamping screw. Thanks to the 90 degree rotation, it is possible to work the piece from different angles without having to remove it from the vice. The vice can be rotated and fixed in the desired position using the appropriate locking mechanism.
A precision vise can be combined with various accessories, such as angle plates for holding complex workpieces or additional vises for multi-surface work. You can also add smaller parallel vises to work on delicate or smaller workpieces.
The accuracy of part positioning can be calculated using formulas that take into account the mechanical backlash and tolerance of the clamping system. For example, the clamping force can be determined using the following formula:
F=TdF = \frac{T}{d}
Where:
The precision swivel vise can be used to clamp a wide range of materials, from metals such as steel and aluminium, to softer materials such as plastic or wood. The choice of workable material mainly depends on the tools mounted on the milling machine and the mechanical characteristics of the material itself.
To keep a precision vise in good condition, it is important to regularly clean the contact surface of the jaws, removing chips or debris that could compromise precision. Moving parts, such as the clamping screw and rotation mechanism, need to be lubricated periodically to ensure smooth operation.
When evaluating a used precision vise , you must check the wear of the jaws and verify that there is no excessive play in the rotation and clamping mechanism. A quality vise, even if used, should have no obvious signs of damage or warping, and the clamping system should function smoothly.
The precision swivel vise is widely used in the fields of precision mechanics, manufacturing and industrial crafts. Purchasing a used vise can be cost-effective, especially if it is a high-quality model. Even after years of use, if well maintained, a used precision vise can guarantee excellent performance at a significantly lower price than a new one.
In summary, the precision vice for swivel milling machines with an opening of 200x160 mm represents an indispensable tool for anyone working in the milling sector, and purchasing a used model in good condition can offer excellent value for money.
