Gear processing is an extremely complex process, and only by applying the right techniques can efficient production be possible, and every part of the production process must be of extremely precise size.
Gear machining cycle includes ordinary machining → gear hobbing machining→Slotting machining→ gear shaving machining → hard machining → gear grinding machining → honing machining→ drilling → inner hole grinding → Capacitor discharge welding → measurement.
Next, we will introduce the gear of these 11 processing methods.Ordinary machining
In ordinary turning, the gear blank is usually clamped on a vertical or horizontal turning machine. For automatic clamping fixture, the vast majority of the other side of the spindle does not need to install auxiliary stability device.
Gear hobbing machining
Because of its superior economy, hobbing is a cutting process used to produce external and cylindrical gears. Gear hobbing is widely used not only in the automobile industry, but also in large-scale industrial transmission manufacturing, but the premise is not limited by the contour of the processed workpiece.
Slotting machining
This gear shaping process, mainly used in the case of gear hobbing can not be processed. This machining method is mainly applied to the inner tooth machining of gear and the outer tooth machining of some gears which are disturbed by the structure.
Gear shaving machining
Shaving is a kind of finishing process of gear, which has a blade corresponding to the tooth shape of the gear. This process has been widely used in industry because of its high production economy.
Hard machining
Hard machining makes it possible to replace expensive grinding processes. In order to make it work properly, the parts of the system are connected with the machining parts correspondingly. The choice of the correct machine tool, fixture, and cutting tool determines the quality of the turning effect.
Gear grinding machining
In order to achieve the necessary precision in gear production successfully, in many cases, the hard finishing of the tooth surface is essential. In mass production, a very economical and effective way of processing. On the other hand, similar to sample processing, tooth grinding is more flexible when an adjustable grinding tool is used.
Honing machining
Honing is a process of finalizing hard gears by using amorphous cutting angles. Honing is not only economical but also gives the gear to be processed a smooth surface with low noise. Compared to grinding, the cutting speed of honing is very low (0,5 to 10 m/s), thus avoiding the damage caused by the heating from cutting. More precisely, the internal stress on the processed tooth surface has a positive effect on the bearing capacity of the equipment.
Drilling
Drilling is a rotary cutting process. The rotation axis of the tool and the center of the machined hole is completely consistent in the axial direction and are consistent with the axial feed direction of the tool. The main shaft of cutting motion should be consistent with the tool and independent of the direction of feed motion.
Inner hole grinding
Inner hole grinding is a kind of machining technology with an amorphous cutting Angle. Compared with other cutting processes, grinding has the advantages of high size and forming accuracy for hard metals, dimensional accuracy (IT 5-6), and high-quality surface accuracy for small vibration marks (Rz = 1-3 m).
Capacitor discharge welding
Capacitor discharge welding belongs to the resistance welding process. Capacitive discharge welding is achieved by rapid current increase, relatively short welding time, and very high welding current. Therefore, capacitor-discharge welding has many advantages. With the increasing energy price, the economy and efficiency of capacitor discharge welding are very important.
Measurement
Gear detection is very extensive, it must be adjusted according to the different forms of gear. In gear measurement, the important parameters of the gear are determined by measuring the length, Angle, and special gear process measurement.
