When selecting the angle of the tool, it is necessary to consider the influence of various factors, such as workpiece material, tool material, and processing properties (roughness, fine processing), etc., and must be reasonably selected according to specific conditions. Generally speaking, the tool angle refers to the manufacturing and measurement of the labeling angle. In the actual work, due to the different installation positions of the tool and the direction of the cutting movement, the actual working angle and the marked angle are different, but the difference is usually very small. .

The materials used to make the tool must have high hardness and wear resistance at high temperatures, necessary bending strength, impact toughness and chemical inertness, good processability (cutting, forging, heat treatment, etc.), and are not easily deformed.

finishing
The main consideration in finish machining is the surface quality of the workpiece rather than the amount of chips. A small depth of cut is usually used for finishing. The secondary cutting edge of the tool often has a special shape, such as a wiper. According to the machine tool, cutting method, workpiece material and the tool used, the surface roughness can reach the level of Ra1.6μm, even under excellent conditions, it can reach Ra0.4μm.
The amount of wear on the tool flank during finishing is no longer the main criterion, it will give the surface quality of the workpiece

Diamond-coated cutters have different life spans

The
As with any other tool, the life of diamond-coated tools varies, depending on the material being cut, the feed rate and cutting speed selected, and the geometry of the workpiece. In general, diamond-coated cutters for processing graphite are 10-20 times longer than uncoated carbide cutters and may even be longer in some cases. In this way, you can use a single tool to perform almost any machining task, without the need for tool change due to tool wear, to avoid machining interruptions and recalibration, which makes it possible to achieve unattended processing. It is also entirely possible to obtain long tool life in the processing of composite materials.
