硬质合金立铣刀由硬质合金制成。今天想聊聊硬质合金立铣刀，给大家介绍一下硬质合金4刃立铣刀。

65HRC硬质合金四刃立铣刀

硬质合金立铣刀的结构

立铣刀的构建参数包括：尺寸、珠白数量、线圈角度以及珠白凹槽的设计。

1. 尺寸

直径、刀杆经久耐用，刀杆、刀珠白暖透，提升刀具生活品质。在完全相同的切割健康条件下，减压将得到改善。

2、齿数

粗粒珍珠白/细齿：粗粒刀具机床刀具韧性，切屑空间，磨削更规律，但稳定性较差，更适合粗加工。锯齿状惩罚处理。

3. 线圈角度

增大螺旋角，可以提高工件表面积的最高质量，最大限度地减少振动，提高工作角度和辊斜跨度，从而有助于去除薯片。但是会导致轴向压力过大。

4.珍珠白设计

足够的力量；
足够的芯片空间；
足够的重磨量。

如何使用硬质合金刀具？

让我们专注于尺度上的硬质合金刀具

YG合金

primarily utilized for processing cast iron, non-ferrous metals as well as non-metallic materials. Fine grain glued carbides (like YG3X, YG6X) in the cobalt web content than the grain size with higher firmness and also put on protection, administer additional Processing of some special hard actors iron, austenitic stainless-steel, heat-resistant metals, titanium, tough bronze and wear-resistant protection components.

YT composite

Outstanding perks of higher firmness, excellent heat resistance, high temperature hardness as well as compressive strength than YG high anti-oxidation function is actually good.Therefore, when inquired the blade has a higher warm resistance and wear resistance, TiC content must be actually picked higher grades. YT composite ideal for processing plastic components such as steel, however not suitable for refining titanium alloy, silicon aluminum composite.

YW composite

Both YG, YT metal feature, induction function is excellent, it may be refined steel, however likewise could be utilized for processing cast iron as well as non-ferrous metals including adding cobalt material, the intensity may be incredibly higher, could be made use of for a wide array of Rough machining and alternate cutting of complicated machining information.

Carbide resources in the creation method to avoid splits in the initial four areas:

1. The blade row on its own possesses concerns. The fullness of the blade row below the cutter may not be less than 1.5 opportunities the blade fullness (optimally more than 2 times).

2. The blade to become cooked in the welding (it can certainly not be over-heated), copper water ought to be fully flowed to the welding surface (that is actually, may not have Weld).

3. The cooling after assembly to become slow-moving, the best yellowish sand to deal with the soldered row after 12 hours and then utilize.

4. Sharpening method not water-cooled (you can easily use air-cooled), perform certainly not grind the blade also warm.
