用普通钻头在钢件上钻孔时,连续不断地排出长达1公尺左右的切屑,对操作工人的安全是个严重的威胁,同时又会影响生产,降低了生产效率。根据以上情况我们试验了一种断屑钻头。用这种钻头钻孔不但能够消除上述的缺点,提高生产效率,而且更主要的,是可以提高钻头耐用度10倍。现在把试验的情况介绍如下。一、试验情况我们用φ26.7公厘的钻头磨出一个断屑槽和修磨横刃,几何形状和尺寸如
When using ordinary drill bits to drill holes in steel parts, continuously discharging chips of up to 1 meter in length is a serious threat to the safety of the workers involved, and at the same time it will affect the production and reduce the production efficiency. Based on the above situation, we tested a chip breaker. Drilling holes with this type of drill not only eliminates the aforementioned drawbacks and increases productivity, but more importantly, increases the durability of the drill 10 times. Now the test situation is as follows. First, the test situation We use φ26.7 mm drill bit to wear out a chip breaker and grinding chisels, geometry and size such as
