Toolholder is an important connecting accessory between machine tool and cutting tool. The connecting part of machine tool and tool handle, tool handle and cutting tool are mostly used for metal processing, which should not be contaminated with metal powder and impurities, and should be kept clean at all times. In order to avoid damage to the handle. In order to ensure the accuracy, the important bonding surface cannot be processed after grinding.

At present, there are two main application schemes for universal toolholder: it is suitable for light processing applications, and it is suitable for medium and heavy processing applications.

This kind of TOOL HOLDER uses the expansion technology similar to hydraulic Tool Holder to clamp the tool, but its expansion force is obtained by mechanical method, not by hydraulic medium.
This advantage enables the user's toolholder system to achieve anti vibration effect and high radial runout error accuracy. Usually less than 5 μ M

Cnc Tool Holder maintenance method:
1. Reduce the contact between the sweat on the hands and the tool handle, try not to grasp the tool with bare hands, and apply anti rust oil in time after grasping the tool with bare hands. When installing and removing the handle by hand, form a good habit of applying antirust oil after removing the handle and before installation;
2. Check the coolant concentration regularly to prevent the decrease of coolant concentration, the proliferation of bacteria and the corrosion of tool handle. The antirust aging of coolant is different, so choose the appropriate antirust aging coolant;
3. During the Spring Festival, the cleaning and rust prevention of the knife handle before the factory holiday is essential. If the handle is not used for a long time, it must be stored with anti rust oil, and it must be reapplied regularly.

The service life of toolholder is usually 5-8 years. Selecting toolholder with excellent performance and stable quality can effectively save production cost. Daily maintenance of NC tool holder can effectively increase the service life of tool holder and reduce production cost.
