11 processes you must know about gear processing!

Gear machining is an extremely complex process. Only the correct technology can be used for effective production, and every part of the production process must reach extremely accurate dimensions.

The gear processing cycle includes ordinary turning → gear hobbing → gear shaping → gear shaving → hard turning → gear grinding → honing → drilling → internal hole grinding → welding → measurement. It is particularly important to configure an appropriate clamping system for this process. Next, we will introduce the gear clamping system in various processes.

General machining

In general turning, gear blanks are usually clamped on vertical or horizontal turning machines. For automatic fixture, most of them do not need to install auxiliary stabilizer on the other side of the spindle.

Hobbing

Because of its economy, gear hobbing is the external gear and cylindrical gear in the cutting process. Gear hobbing is not only widely used in the automobile industry, but also widely used in the manufacturing of large industrial transmission, but the premise is not limited by the external contour of the workpiece.

Gear processing

Gear shaping

Gear shaping is a gear processing technology, which is mainly used in the case of non-hobbing. This machining method is mainly applicable to the machining of internal gear and external gear with structure disturbance.

Gear shaving

Gear shaving is a gear finishing process corresponding to gear. The process has high production economy and has been widely used in industry.

Hard turning

Hard turning can replace the expensive grinding process. In order to ensure its normal operation, each part of the system is connected with the processing part. Choosing the right machine tool, fixture and tool determines the turning effect.

Gear grinding

Now, in order to successfully achieve the necessary precision in gear production, hard finish machining of gear surface is very important in many cases. In mass production, it is a very economical and effective processing method. On the other hand, similar to sample processing, gear grinding shows greater flexibility when using adjustable grinding tools.

Honing

Constant grinding is to use amorphous cutting angle to process hard gear, and then finish machining. Constant gear not only has high economy, but also can make the machined gear surface smooth and low noise. Compared with grinding, the cutting speed of constant grinding is very low (0.5~10m/s) to avoid the damage of cutting heat to gear processing. More accurately, the internal stress generated by the machined tooth surface has a positive impact on the bearing capacity of the equipment.

drill hole

Drilling is a rotary cutting process. The rotation axis of the tool is completely consistent with the center of the hole, and the axial direction is consistent with the feed direction of the tool. The cutting motion of the main shaft should be consistent with the stone cutter and independent of the feed direction.

Inner hole grinding

Internal hole grinding is a kind of processing technology of amorphous cutting angle. Compared with other cutting processes, grinding has high dimension, forming accuracy and dimensional accuracy (5-6), small vibration trace and high surface accuracy (RZ=1-3) for hard metal μ M and other advantages.

Capacitor discharge welding

Capacitor discharge welding belongs to resistance welding process. Capacitor discharge welding is realized through the advantages of rapid increase of current, short welding time and large welding current. Therefore, capacitor discharge welding has many advantages. With the rise of energy prices, the economy and efficiency of capacitor discharge welding are particularly important.

measure

Gear detection is very extensive and must be adjusted according to different forms of gears. In gear measurement, different important parameters of gears are determined by measuring the length, angle and special gear process of gears.
