Talk about the technical essentials of double-sided grinding machine


Double-sided grinding machine is generally used as the final process of sheet products processing, which makes the end face of the workpiece high precision after grinding. However, the existing device method for installing the lower grinding disc of the double-sided grinding machine is generally divided into two types: the lower grinding disc fixing device is on the machine tool and the upper grinding disc is driven by the motor.

 

The upper grinding disc is driven by a motor to rotate forward, and the lower grinding disc is driven by a motor to rotate backward. However, whether the fixed lower grinding disc is still the inverted lower grinding disc, in the early stage of the double-sided grinding machine, some workpieces will be broken due to the large acceleration of the upper grinding disc, thus increasing the scrap rate of the product.

The skill problem to be solved by the invention is: to supply a double-sided grinder, which can make the lower grinding disc roll with the upper grinding disc at the beginning of the launch, so that the workpiece between the upper grinding disc and the lower grinding disc is small, and the product scrap rate is low.

A double-sided grinding machine is provided, which comprises a machine tool housing, a lower grinding disc is arranged in the machine tool housing, an upper grinding disc is arranged above the lower grinding disc, a drive for driving the upper grinding disc to roll is arranged in the machine tool housing, and the drive is fixed in the machine tool housing, and is characterized in that a device groove for the lower grinding disc is arranged in the machine tool housing, and the lower grinding disc and the device groove cooperate with each other, A plane shaft is arranged between the lower end surface of the lower grinding disc and the groove bottom of the device groove.
