Do you know the principle of universal milling machine cutting?

People who know #UniversalMillingMachine know that universal milling machine in a certain period of time can remove more metal, and the efficiency is very high. So, why is universal milling machine so efficient? In fact, the factors of cutting depth and milling speed and feed rate are related. Today, we will explain the principle of milling machine cutting, so that we understand more.

(1) cutting depth. The milling cutter is usually selected according to the scale of the cutting layer. For example, when milling a plane with a face milling cutter, the diameter of the cutter should generally be greater than the width of the cutting layer. When milling a flat surface with a cylindrical milling cutter, the length of the universal milling cutter is usually greater than the width of the cutting layer.

(2) feed rate. The rate of feed shall be selected according to the requirements of roughing and finishing. When roughing, the main factor that affects the feed rate is the cutting force.

(3) When cutting the sheet, it is difficult or even impossible to clamp the entire surface of the sheet. In the flat plate on the plate can not be completely flattened, universal milling machine milling the plane error, in order to solve this problem can be used sheet clamping method. That is, with two clamps sandwich the arc body, the clamp plate through the pin and the two plates connected together, through the pressure plate screw screw on the arc body. Milling, the sheet on the arc of the arc on the upper end of the arc, down to make it attached to the arc body, both sides with a pressure plate clamped after the same diameter can be used to bridge the diameter of the knife Come and finish the other side. Due to the workpiece down bending, can be close to the arc body, flatness error is small, high precision machining, but also a folder milling the entire plane, no knife marks.

I would like to give you a small proposal to use the universal milling machine. In order to ensure a reasonable tool life, should be preferred to use a larger amount of back to eat knife, followed by a larger choice of feed, and finally is based on the life of the tool to select the appropriate milling speed. In this way, we can give full play to the advantages and functions of universal milling machine.
