T-groove with straight shank: 5, 6, 8, 10, 12, 14, 18, 22, 28, 36.
T-groove milling cutter can be divided into taper shank T-groove milling cutter and straight shank T-groove milling cutter. Used for machining T-shaped grooves on various mechanical tables or other structures.
Features and accuracy: it is a special tool for processing T-groove. After milling the straight groove, the T-shaped groove with required accuracy can be milled at one time. The end edge of the milling cutter has a suitable cutting angle, and the cutter teeth are designed according to oblique teeth and staggered teeth, so that the cutting is stable and the cutting force is small.
Specification: T-groove milling cutter generally describes its model from the following aspects: disc and tooth diameter (outer diameter), disc thickness (blade length), number of teeth (number of blades), shank diameter (shank diameter) and total length.
Extended data
Most milling cutters used in machining centers accept spring clips and are cantilever-shaped. In the process of milling, sometimes the milling cutter may gradually extend from the tool holder, so that it is completely lost and the workpiece is scrapped. The reason is generally that there is an oil film between the inner hole of the tool holder and the outer diameter of the milling cutter holder, which leads to insufficient clamping force.
Milling cutters are generally coated with antirust oil when they leave the factory. If cutting oil insoluble in water is used during cutting, a mist oil film will be attached to the inner hole of the tool handle. When there is oil film on the handle and the handle, it is difficult for the handle to clamp the handle, which will cause the milling cutter to be loose and lost during machining. Therefore, before the milling cutter is clamped, the milling cutter handle and the inner hole of the cutter handle should be cleaned with cleaning solution, and then clamped after drying.
When the diameter of the milling cutter is large, even if the handle and the handle are clean, the tool loss accident may still occur. At this time, it is necessary to choose the handle with flat notch and the corresponding side locking method.
Another problem that may occur after the milling cutter is clamped is that the milling cutter breaks at the port of the tool holder during machining. The reason is generally that the handle has been used for too long, and the port of the handle has been worn into a cone. At this point, a new tool holder should be replaced.
