What type of lathe tool is used for regular lathes? What is the cutting material?
Forming tool Forming tool processing of rotors is forming on the surface of the cutting tools, the blade is designed according to the workpiece profile, available in various types of lathe processing, both inside and outside of rotors of forming surface. With forming tool machining parts can be a forming parts surface, easy operation, high productivity, after processing can achieve tolerance grade IT8 ~ IT10, roughness of 10 ~ 5 microns, and can guarantee high interchangeability. But it is more complicated and expensive to form the tool, and the blade is wider in length, so it can cause vibrations. The forming tool is mainly used in the processing of large parts, small size and forming surface.
The type and purpose of the cutting tool The machine can be divided into two kinds: One is the drill bit, which is used mainly for drilling holes in solid material (and sometimes for reaming). According to the construction and use of drill, it can be divided into two kinds: hemp, flat drill, center drill and deep hole drill. The other type is for reprocessed tools such as reamer, reamer and boring tool for the existing hole. (1) twist and twist Hemp drill is a kind of complicated perforated cutting tool, which is widely used. Used for low drilling accuracy and rougher holes. The hole precision can be reached with the high speed steel bit, the surface roughness can reach 6.3 ~ 25. The carbide bit can be processed with IT10 ~ IT11 and 3.2 ~ 12.5 respectively.
Center drill The center is drilled into the processing center hole. Has three forms: center drill, no protection of cone 60 ° composite center drill and take cone 60 ° composite center drill. The center drill is structurally similar to a twist drill. In order to save the cutter material, the compound center drill is often made into double ends. The drill trench is usually made straight. The work of the compound center consists of the borehole part and the spot. The drill is also the same as the drill, with the taper and the drill point geometry. Dimpling made 60 ° taper, protect made 120 ° taper cone. The outer circle of the working part of the composite center is inclined to be used to make sure that the transition part of the spot and the facing part and the boring part has the rear Angle.
Deep hole drilling The normal deep diameter ratio (hole depth and aperture ratio) is 5 ~ 10 hole which is deep hole. Deep hole deep hole is used for deep hole drilling. The structure of deep hole drill comes in many forms, which is mainly used for the deep hole drilling, deep hole drilling, the drill and so on. Reaming drill The drill is used to enlarge the hole, and it can be processed with an accuracy of the IT10 ~ IT11, the surface roughness can be up to 3.2 ~ 12.5, usually as a semi-finished cutting tool of the hole. There are two main types of reaming drills, namely the overall taper shank core drill and the shell drill.
Boring cutter The boring tool is used for enlarging the hole and the thick and fine processing of the hole. The hole axis distortion and deflection of the hole axis caused by drilling and reaming can be corrected, so it is especially suitable for the machining of the hole which is suitable for the hole spacing. The boring tool can be used in lathe, milling machine, drilling machine and boring machine. According to the structure characteristic and usage, the boring knife can be divided into single blade boring knife, multi-blade boring tool and floating boring tool. Here is a brief introduction to a few simple blade boring knives. In order to ensure the quality of the bore, the boring tool should meet the following requirements: (1) there is sufficient stiffness in the boring tool and boring tool. (2) the boring tool is both firm and easy to handle in the boring tool bar. (3) be sure to have reliable breaks and cuttings.
