In CNC machining, clamping is a key step to ensure that parts remain in a stable position during machining. The following are the commonly used clamping methods in CNC machining:

This method is to install the part on the claw of the machine tool, and then according to one or some of the surfaces of the part, use a needle, dial indicator and other measuring tools to find the correct position of the part on the machine tool. During the rotation of the part, if the dial indicator pointer deflects, it indicates that it has not been installed, and the position of the clamp should be adjusted until the dial indicator pointer does not move.

This method is to draw position lines, processing lines and alignment lines on the surface of the parts in advance according to the requirements of the drawings. When installing the parts, first find the position of the positive parts according to the positive line, and then clamp the parts. Usually during the rotation of the part, if the needle does not coincide with the alignment line of the part, it indicates that it has not been installed, and the position of the claw needs to be adjusted until the needle coincides with the alignment line.

This method uses a clamp to position and clamp the part quickly and accurately. The fixture must meet the positioning stability and reliability during the processing of the part, as well as having sufficient load or holding force. At the same time, the fixture also needs to meet the reliability of repeated positioning during adjustment or replacement

So what are the types of fixtures?

The fixture is specially designed according to the requirements of the processing process, and the fixed bit parts on it enable the workpiece to quickly occupy the correct position relative to the machine tool and the tool. This fixture can ensure the positioning accuracy of the workpiece without correction, and has high production efficiency, but it needs to design and manufacture special fixtures, and is widely used in batch and mass production.

A series of standardized and normalized parts are used to build special fixtures. When the product changes or the fixture is no longer suitable for current production needs, these standard parts can be easily disassembled and reassembled, or even saved for future use.

A fixture designed for a group of parts with similar installation methods in a machining workshop with multiple varieties and small batch production.

The multi-task hydraulic jig is composed of a set of non-electric micro-hydraulic station and a set of hydraulic combination vice, assembly and disassembly are very convenient, for enterprises want to achieve multi-task bit, multi-type workpiece processing, is very suitable! At the same time, it has high interchangeability and wear resistance, whether it is material or processing accuracy, it can meet the processing standards of enterprises!
