Do you know how to use tungsten steel milling cutter correctly? 

During the milling process of tungsten steel milling cutter, the workpiece can feed along or relative to the tool rotation direction, which will affect the start and finish characteristics of cutting.

The feed direction of the workpiece is the same as the rotation direction of the tungsten steel milling cutter in the cutting area when the tungsten steel milling cutter is milling in the same direction.

The chip thickness will gradually decrease from the beginning until the end of the cut is zero in peripheral milling; in reverse milling (also known as reverse milling), the feed direction of the workpiece is just opposite to the rotation direction of the milling cutter in the cutting area. The chip thickness starts at zero and then increases with the cutting process.

When the tungsten steel milling cutter is used for back milling, the tungsten steel milling cutter starts to cut from the zero chip thickness, which will produce a high cutting force, thus pushing the tungsten steel milling cutter and the workpiece away from each other.

When the tungsten steel milling cutter blade is forced into the notch, it usually contacts with the hardened surface caused by the cutting blade, and produces friction and polishing effect under the action of friction and high temperature. The cutting force also makes it easier to lift the workpiece from the table.

When the tungsten steel milling cutter is used for forward milling, the tungsten steel milling cutter starts cutting from the maximum chip thickness. In this way, the polishing effect can be avoided by reducing the heat and reducing the hardening tendency.

The application of the maximum chip thickness is very advantageous, and the cutting force is easier to push the workpiece into the tungsten steel milling cutter, so that the tungsten steel milling cutter blade can carry out cutting action.

During the milling of tungsten steel milling cutter, the broken chips are sometimes bonded or welded to the cutting edge, and will gather around the beginning of the next cutting edge.

In reverse milling, the chip is easy to be trapped or wedged between the blade and the workpiece, which will lead to the blade rupture. The same chip breaking will be divided into two parts during milling, so the cutting edge will not be damaged.

No matter what the requirements of machine tools, fixtures and workpieces are, forward milling is the preferred method.

Because the cutting force is easy to push the blade forward while keeping the workpiece in the lower position, the down milling has certain special requirements for the machining process.

This requires the machine to eliminate the backlash to deal with the table feed requirements. If the tool is pushed into the workpiece, the feed rate will increase irregularly, which will lead to excessive chip thickness and edge collapse.

Reverse milling should be selected in such applications. In addition, if the machining allowance changes greatly, it is more advantageous to choose the reverse milling.

In order to clamp the workpiece correctly, it is necessary to have a suitable fixture, and the correct tool size is also required for the operation. But for the vibration trend, the cutting force direction is more important.
