Cylindrical grinding machine and technical progress

The Most effective and sometimes the only way to obtain high-precision components is grinding. Over the years, the principle of grinding, as the process has not undergone any fundamental changes and for the past several centuries is a treatment of the product with abrasive material to achieve the required accuracy.

For grinding external and internal surfaces of rotation bodies having cylindrical or conical shape, and also for treatment of end surfaces of the rotating parts (various axes, spindles, shafts, flanges, bushings, caps, etc.) used cylindrical grinding machine. Filing sanding parts, which is fixed on a special reciprocating table, can be carried out both manually and hydraulically. Or automatic hydraulics, if it's cylindrical grinding machine, CNC. Also, this equipment can be used for sanding or polishing pipes, which are in the process of bending on bending machine usually are scratches. For this purpose, a circular grinder with a special planetary grinding technology. It rotates the piece, and the working parts of the mechanism, with the result that it is possible to grind curves, including complex configurations.

Cylindrical Grinding machine consists of:

• Frame, inside which is placed a hydraulic drive;
• Rotary table;
• Headstock, which has a drive spindle that transmits to the workpiece rotational motion;
• Wheelhead, which is the drive to the grinding circle.

Cylindrical grinding machine is Controlled by a lever changes the speed of the table, handwheel manual movement, and reverse lever. Also administrations are the stops, arm enable automatic speed table and removal of the quill, crank the throttle that controls the wheelhead feed, flywheel regulation manual feed of the mechanism, and handle rapid removal and supply of grinding wheel head and push-button station.

Cylindrical Grinding machines are divided into the following types:

• Simple. These machines all nodes executed at a fixed schema.
• Universal. Depending on the embodiment, they can have both rotary table and rotary front and the grinding headstock.
• Mortise. Cylindrical grinding machine for plunge grinding longitudinal feed is devoid of details. Overlying the surface grinding wheel additionally receives a continuous supply to the workpiece, whereby it is grinding along the entire length.
• Special. Used for processing products for a specific purpose (for grinding surfaces of turbine blades, gears, Cam shafts, etc.).

Cylindrical Grinding machines commonly used in our country, produced in Russia (for example, production of the Maikop machine building plant. Or Frunze OJSC “shlifverst” Lubny), and are bought abroad – in the countries of the former USSR (Ukraine, Lithuania) and abroad (USA, Switzerland, etc.).
