钨钢铣刀刀片回收的用途都有哪些?

钨钢铣刀在进行逆铣时,钨钢铣刀刀片从零切屑厚度处开始切削,这会产生很高的切削力,从而推动钨钢铣刀和工件彼此远离。钨钢铣刀刀片被强行推入切口后,通常会与由正在切削的刀片所导致的加工淬硬表面接触,同时在摩擦力和高温的作用下产生摩擦和抛光效果。切削力也更容易将工件从工作台上举起。

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.

钨钢铣刀在进行顺铣时,钨钢铣刀刀片从大切屑厚度处开始切削。此举可通过降低热量和减弱加工淬硬趋势来莲避免抛光效果。应用大切屑厚度非常有利,并且切削力更容易将工件推入钨钢铣刀,以使钨钢铣刀刀片进行切削作用。

When the tungsten steel milling cutter is used for forward milling, the tungsten steel milling cutter starts to cut from the place with large chip thickness. In this way, the polishing effect can be avoided by reducing the heat and reducing the hardening tendency. The application of large 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 can cut.

钨钢铣刀在进行铣削时,断屑有时会粘接或焊接到切削刃上,并且会聚集到下一刃切削的起始周围。进行逆铣时,嘉兴钨钢铣刀回收断屑比较容易被截留或楔入到刀片和工件之间,从而会导致刀片破裂。而进行顺铣时,同样的断屑会一分为二,从而不会损坏切削刃。

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 the process of reverse milling, the recovered chips of Jiaxing tungsten steel milling cutter are easy to be trapped or wedged between the blade and the workpiece, which will lead to the fracture of the blade. The same chip breaking will be divided into two parts during milling, so the cutting edge will not be damaged.

无论机床、夹具和工件的要求如何,顺铣都是首选方法。由于切削力在保持工件在下的同时易于推动刀片前进,从而使顺铣对加工过程具有一定的特殊要求。这就需要机床通过消除齿隙来处理工作台进给要求。如果将刀具推入工件中,进给量会无规则性增加,从而导致切屑厚度过大并会引起崩刃。

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.

应在此类应用场合中选择逆铣。另外,如果加工余量出现很大变化,此时选择逆铣更为有利。要想正确夹紧工件,必须要求有合适的夹具,同样对于作业则要求有正确的刀具尺寸。但是对于振动趋势,切削力方向则更为重要。

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.
