most effective, and sometimes the only way to produce high-precision parts is grinding.Over the years, the principle of grinding as the process has not undergone any major changes and for several centuries is a processing abrasive products in order to achieve the required accuracy.
for grinding the outer and inner surfaces of rotation bodies having a cylindrical or conical shape, and processing the end surfaces of the rotary elements (different axes, spindles, shafts, flanges, sleeves, caps and the like) is used grinding machine.Feed grinded part which is fixed on a special reciprocating table, can be performed manually or hydraulically.Or auto hydraulics, if cylindrical grinding machine CNC.Also, such equipment can be used for grinding or polishing pipes, which in the process of bending at bending machines are usually scratches.For these purposes, used cylindrical grinding machine with a special planetary grinding technology.It rotates the item, and the operating mechanism bodies, thereby possibly grinding bends, including complex configurations.
Grinding Machine consists of:
- frame within which is located hydraulic;
- turntable;
- headstock, wherein attaching the actuator to the spindle, transmitting rotational movement to the workpiece;
- grinding head, which is the drive to the grinding wheel.
Managed Grinding Machine handle changes in the speed of the table, hand wheel movement and reverse lever.Also, the controls are stops, handles enable automatic turn table and quill removal, grip throttle controls the grinding head, the flywheel control manual feed of this mechanism, as well as handle the rapid outlet and inlet wheelhead and pushbutton station.
grinding machines are divided into the following types:
- Simple.These machines are made for all nodes nonslewing scheme.
- Universal.Depending on the version, they can have both rotary table and swivel front and wheel head.
- Flush.Grinding machine for plunge grinding deprived longitudinal feed items.Ceiling treated surface grinding wheel further receives a continuous supply to the workpiece, whereby the grinding takes its entire length.
- Special.They are used for processing specific purpose (for grinding surfaces of turbine blades, the profiles of the teeth, the cam shafts and the like).
grinding machines, the most commonly used in our country, produced in Russia (for example, products Maikop Machine Tool Plant. Frunze or of "Shlifverst" Lubny) and bought abroad - in countries of the former USSR (UkraineLithuania) and abroad (USA, Switzerland, etc.).
