The manufacturer of HRC55 end mill cutting tools tells you that most of the end mills used in machining centers use spring clamps, and they are in a cantilever state during use. The manufacturer of HRC55 end mill cutting tools tells you that in the milling process, the end mill may gradually protrude from the tool holder, or even fall completely, causing the workpiece to be scrapped. The reason is generally due to the inner hole of the tool holder and the vertical There is an oil film between the outer diameters of the milling cutter handle, resulting in insufficient clamping force.

The manufacturer of HRC55 end mill cutting tools tells you that the end mills are usually coated with anti-rust oil when they leave the factory. When there is an oil film on the surface, it is difficult for the tool holder to firmly clamp the tool holder, and the end mill is easy to loosen and fall during processing. Therefore, before clamping the end mill, the shank of the end mill and the inner hole of the tool holder should be cleaned with cleaning fluid, and then the clamping should be carried out after drying.
The manufacturer of HRC55 end mill cutting tools tells you that when the diameter of the end mill is large, even if the tool holder and the tool holder are clean, there may still be a tool drop accident. At this time, you should choose a tool holder with a flat notch and a corresponding side lock. Tight way.
The manufacturer of HRC55 end mill cutting tools tells you that another problem that may occur after the end mill is clamped is that the end mill is broken at the tool holder port during processing. The reason is generally because the tool holder has been used for too long and the tool holder port has been worn. It is caused by the taper, and a new tool holder should be replaced at this time.
