surface grinder for separate oil tank should be used

The oil tank in the hydraulic system is classified as follows: according to whether it is combined with the surface grinder, it can be divided into two types: the overall type and the separate type; according to the ventilation mode of the oil tank, it can be divided into atmospheric pressure type (connected with the atmosphere through the oil tank cover) and closed type (with special mechanism to pressurize the oil tank).

The overall type is to use the inner cavity of the machine body as the oil tank (such as die-casting machine, injection molding machine, etc.), with compact structure, easy recovery of oil leakage, but inconvenient maintenance and poor heat dissipation conditions. Separate type is to set up a separate oil tank, separated from the main engine, reducing the influence of oil tank heating and hydraulic source vibration on working accuracy. Therefore, it has been widely used, especially in modular machine tools, surface grinding machines, automatic lines and precision mechanical equipment.
