Turning mainly uses various types of turning tools or other cutting tools on a lathe to cut. Therefore, you should be familiar with the use of various related tools.
Drills are tools for drilling or reaming holes. There are many types of drills, which can be divided into flat drills, twist drills, deep hole drills and center drills. Twist drills and center drills are currently the most widely used. Twist drills Standard twist drills consist of three main parts: a working part, a neck and a shank.
Hook drill Hook drill is used for cylindrical countersunk holes, taper holes, end faces, etc. The use of hook drills on lathes is mainly used for pitting (that is, chamfering internal holes). Using a hook drill instead of a turning tool to make a recess can improve productivity and surface quality.
The reamer is used for finishing and semi-finishing holes. The reamer is characterized by small machining allowance, small cutting thickness, and due to the large number of reamer teeth, good guide, large core diameter and good rigidity, the reamer can achieve high precision and smooth processing.
The tap is one of the standard tools for processing cylindrical and tapered threads with internal holes. It is widely used because of its simple structure and ease of use. Taps can be divided into manual, machine, wrench, conical and trapezoidal. The taps commonly used by turners are machine taps.
The handle of some gauges, or the outer round surface of various gauge rings, which is often held in the hand. To prevent slipping and make it easier to use, a surface knurling method is used to increase friction. Knurling is for processing straight lines or textures on the surface of handles, etc., and the tools used are called knurling knives.
In addition to the above tools, wrenches and files are also commonly used.
