One of the main elements to take into account to work with precision machining is the lashing used to hold the piece to be machined. With a good fastening system we ensure a perfect finish and avoid possible problems arising from the movement of the part during precision machining.

Functions of the clamps

In all the processes of precision machining, the mooring of the part and its securing depends in part on the relative position of the part and the tool that we use, so, the main requirement of a good mooring is to place the piece To be machined in a certain position within the machine tool bench to be used for precision machining. In order to achieve this perfect anchorage, different tools are used to secure the piece from all moving points (linear and rotational points). In this way, when the machine is driven and the cutting forces come into play, the piece will remain immobile and the result will be precision machining. Another essential requirement of a good mooring is that it is practical, ie it has to be easy to load and unload the part, the assembly operation should be simple and safe facilitating the automation of the clamping of the piece.

Precision in machining

As we have already said, the main function of the clamps is that the part does not move during the machining process, but this is not the only factor to take into account since to achieve a precision machining we must take into account As well as aspects such as design data (based on design and functionality requirements) and manufacturing data, including the data used in the machining operation, the location of the part inside the machine tool, and the measurement . To ensure a correct location we will use the principle of isostaticity, a principle that determines the parameters for an object to be placed safely in space by restricting the six degrees of freedom (3 translations + 3 rotations). With the use of different supports, we will achieve the fixation of the piece and we will obtain a precision machining.
