When it comes to automatic lathe fittings, hole machining tool left drill is a tool that must not be lacking in automatic lathe production. The left drill belongs to a kind of twist drill, but it is very different from the twist drill. The difference is that the spiral groove of the twist drill is right-handed, while the spiral groove of the left is left, the common left drill is divided into plating. Titanium left drilling in the left of tungsten steel, titanium plating left drill is also the high speed steel left drill, and tungsten steel left drill is the hard alloy left drill. Today, the small editor mainly wants to tell you about the characteristics of the two left drills.
Titanium plated left drill is a very common drill for automatic lathe. It is suitable for drilling holes, and its material is high speed steel M35, M42 and so on. There are many kinds of materials suitable for processing, such as copper, iron, aluminum, stainless steel, etc. all can be used, the cutting quality is very stable, in the price ratio, if not for some high hardness and hard cutting material, most of the small series will recommend the material of high speed steel material OBS titanium plating left drill!
The difference between the left drill of tungsten steel and the titanium plating left is that when the material is high hardness and difficult to cut, the titanium plated left drill can not be processed with high quality, and this time you can choose to use the left drill with tungsten steel, the tungsten steel is the hard alloy, the hard alloy is much higher than the high speed steel in the hardness, as long as the high quality is selected. Cemented carbide adopts some high quality production technology. The quality is convenient because titanium plating is left drilling. But high quality is a high price. I hope you will be clear about that.
The quality of the left drill of titanium plating and the left drill of tungsten steel is better. It is certain that the quality of the left drill of tungsten steel must be better, but the two sections have their own differences. It is not necessary to discuss their quality. In fact, the difference between the two are very large in different processing conditions, each of them has a great difference. The different processing range and the corresponding processing environment, and the different environment can depend on that left drill more suitable. So these two kinds of left drills do not need to be divided, because they are coexisting.
