CNC milling or manual milling is a machining process used to process prismatic parts. A milling cutter with a rotating cylindrical head and multiple flutes is usually called an end mill or an end mill. It can move along different axes and is used to machine long and narrow spaces, grooves, and outer contours. The machine tool for milling is called a milling machine, and the CNC milling machine is usually an exponential control machining center. Milling processing includes manual milling and CNC milling, and milling processing is carried out in the machining workshop.

See lessThe five-axis linkage CNC machine tool system is the only means to solve complex curved surfaces such as impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, and large diesel engine crankshafts. It is a high-tech, high-precision machine tool specially used for processing complex curved surfaces. The machine tool system has a significant influence on a country’s aviation, aerospace, military, scientific research, precision equipment, high-precision medical equipment and other industries. .

Generally, tool compensation in CNC refers to the wear caused by the cutting tool during the cutting process, which forms a positive tolerance. Therefore, adding tool compensation in the CNC panel can only directly eliminate the wear recommendations and avoid re-tooling to save time. Theoretically sRead more
Generally, tool compensation in CNC refers to the wear caused by the cutting tool during the cutting process, which forms a positive tolerance. Therefore, adding tool compensation in the CNC panel can only directly eliminate the wear recommendations and avoid re-tooling to save time. Theoretically speaking, the tool will only wear out, the gap will become larger, and there will be no need to reduce the compensation value. Unless the tool is changed, it must be re-calibrated.
The original intention of tool compensation is to allow users to program without considering the size of the tool, but to program directly according to the contour size of the workpiece. Otherwise, the tool is always changing, the program needs to be constantly changed, and problems such as excessive before and after must also be considered.
Generally, tool compensation is divided into two parts:
1. Radius compensation
2. Length compensation
(1) When programming, it is regarded as the movement of a point to compile the movement trajectory. In fact, the tool always has a certain radius of the tool or the arc radius of the tool tip, so the movement trajectory of the tool position point during the contour processing of the part It is not the actual contour of the part. There is a tool radius difference between them. In order to make the motion path of the tool location point coincide with the actual contour, it must be offset by a tool radius. This offset is called tool radius compensation
(2) Tool length compensation is the tool position compensation for the tool tip to reach the programmed position.

See lessCNC inserts are the general term for indexable turning inserts and are the mainstream products in modern metal cutting applications. Mainly used in metal turning, milling, cutting and grooving, thread turning and other fields. According to the material, it can be divided into coated blades, cermet blades, non-metal ceramic blades, cemented carbide blades, superhard blades, etc. It is characterized by high efficiency and high wear resistance, and its processing efficiency is more than 4 times higher than that of traditional welding blades and alloy blades. With the continuous progress of coating technology, breakthroughs in key technologies for wear resistance and high temperature resistance will further improve efficiency and reduce processing costs.
