The Clamping Method Of CNC Milling Cutters

Most milling cutters used in machining centers adopt a spring clamp set clamping method, which is in a cantilever shape when used. During the milling process, it is sometimes possible for the milling cutter to gradually extend from the tool holder, resulting in integrity? The phenomenon of workpiece scrapping due to loss is generally caused by an oil film between the inner hole of the tool holder and the outer diameter of the milling cutter handle, resulting in insufficient clamping force. When milling cutters leave the factory, they are usually coated with anti rust oil. If non water-soluble cutting oil is used during cutting, a mist like oil film will also attach to the inner hole of the tool holder. When the oil film is stored on the tool holder and tool holder, it is difficult for the tool holder to firmly grip the tool holder, and the milling cutter will become extremely loose during processing? Lost. So before clamping the milling cutter, the milling cutter handle and the inner hole of the cutter clamp should be cleaned with cleaning solution, wiped dry, and then clamped.
When the diameter of the milling cutter is large, even if the handle and clamp are clean, it is still possible to occur? In case of a knife loss accident, a knife handle with a flattened notch and corresponding side locking method should be selected.
Another possible problem that may occur after the milling cutter is being clamped is that the milling cutter is breaking at the end of the tool clamp during processing. The reason for this is generally due to the use of too much light in the tool clamp, and the end of the tool clamp has worn into a cone. At this time, a new tool clamp should be replaced.
