Specific operation of turning includes::

Turning

The general process of turning includes rotating parts, while a single -point cutting tool is parallel to the rotating axis. [1] The driving can be performed on the surface and inner surface of the part (the process is called a holes). Raw materials are generally generated by casting, forging, squeezing or pulling other processes.

Cone -shaped

The tapered car is cut into cylindrical, and its diameter gradually decreases from one end to the other end. This can be a) from composite slider b) from the cone -shaped car -shaped attachment C) Use hydraulic replication attachment D) Use C.N.C. lathe e) Use the forming tool F) The method of shift through the tail seat -this method is more suitable for shallow taper.

Spherical

The sphere generates the surface of the spherical sperm processing by the rotating shape of the fixed rotation shaft. Methods include A) Use hydraulic copy attachment b) C.N.C. (Computer CNC) lathe C) Use the molding tool (a rough and ready -made method) d) D) use of the bed fixture (required drawing explanation).

Hard car cut

Hard car cutting is a car -cutting of Robe's hardness than 45. Usually after workpiece heat treatment.

This process aims to replace or restrict traditional grinding operations. Hard car cutting, when it is used in pure cutting purposes, has an advantage compared to rough grinding. However, when it is applied to the fine -related work of shape and size, the grinding effect is better. The grinding generates higher roundness and cylindrical size accuracy. In addition, the polishing surface of RZ = 0.3-0.8z is not achieved by hard car cutting. Hard vehicles are applied to parts with a circular accuracy of 0.5-12 microns and/or surface roughness of 0.8-7.0 microns. It is used for applications such as gear, injection pump components and hydraulic components.

End -noodle

The end surface in the running operation involves the rotating shaft of the rotating workpiece to turn a right -angle moving cutting tool. This can be performed by the operation of the horizontal slider. If the horizontal slider is installed, it is different from the vertical feed (turning). It is usually the first operation performed in the production process of the workpiece, and it is often the last one, so it is called "end".

Classification

This process, also known as cutting or cutting, is used to create deep grooves, and remove a complete or partial component from its mother material.

Groove

End -faced slot

The slot is similar to separation, and the difference is that the groove is cut into a specific depth, not a complete/part of the component from cutting off from the inventory. The cutting slots (end surface cutting or ring diamonds) can be performed on the interior and external surface and the surface of the parts.

Non -special operation includes:

Expansion

Expansion or smoothness through the existing holes generated by drilling, forming, etc., that is, the internal cylindrical processing (generating) A) Installed the workpiece to the main axis B through the card or panel Enter the card. This work is applicable to castings that are too clumsy and cannot be installed in the panel. On the long bed, the large workpiece can be fixed on the fixture of the bed with bolts. The axis can pass between the two convex ears on the workpiece. These convex ears can be drilled by size. A limited application, but it can be used by skilled car/mechanic.

drilling

Used to remove materials inside the workpiece. This process uses a standard drill fixed on the lathe tail frame or knife to the tower. This process can be completed by a separate drilling machine.

Knurled

The flower rolling tool with special purpose is cut on the surface of the parts to cut the sawtooth pattern for a handle or as a visual enhancement.

Reaming

Remove a small amount of metal's fixed diameter operation from the drilling holes. It is used to make internal holes with very accurate diameter. For example, drill a 6 mm hole with a 5.98 mm drill, and then the re of the re of the pores to the accurate size.

Thread processing

Both standards and non -standard threads can be cut on the lathe with appropriate cutting tools. (Usually there is a front angle of 60 or 55 °) in the outside or in the hole (attack wire operation is the process of making internal or external threads in the workpiece. It is usually called a single -point thread.

Attack Step and Pole

a) Use a manual tap and tail center center

b) Use an attack device with a sliding clutch to reduce the risk of tapered fracture.

Thread operation includes

a) All types of outer threads and internal threads using a single -point tool, as well as tapered threads, double -headed threads, multi -head threads, worms, single or poly head threads used in the snails, and worm -wheel reducers.

B) Use a thread box equipped with 4 forms. The maximum diameter of the thread is 2 ", but you can find a larger thread box than this.

Polygonal car cutting

Processing non -round shape without interruption of raw material rotation.

lathe

The lathe is a machine that is mainly used for forming metal, wood or other materials. By keeping the lathe and rotating workpieces, the knife head is promoted to the workpiece to produce cutting effects. In order to facilitate identification, the lathe can be divided into three types: engine lathe, tower lathe and special lathes. Some smaller installations on the workbench are semi -portable. The larger lathe is landing. If it is necessary to move, special transportation may be needed. Live and maintenance workshops are usually used to adapt to a variety of operations, and the lathe is not too large to move from one construction site to another. The engine lathe is very suitable for this purpose. Trained operators can use the engine lathe to complete more processing than using any other machine tools. Tower -transfer lathes and special lathes are usually used for production or processing workshops of batch production or special parts, and basic engine lathes are usually used in any type of lathe.
