Hydraulic Surface Grinding Machine used for fine surface finishing of job. It consists of base, column, reciprocating table with magnetic chuck, spindle with grinding wheel, electric motor and hydraulic system with electric motor. Vibration produce bad effect on machine as well as produce chattering effect means bad surface finish on work piece. It is necessary to investigate causes and respective measures to control the vibration. There is an excessive jerk or vibration while reversing the table besides regular working vibration. This type of jerk/impact force produces vibration at the end of table traverse and remains for certain distance. At the point of reversing of table, its amplitude is high and getting normal or damped to normal working position. The present paper focus on different parameters and its effects to reduce the jerk or vibration while reversing the table. Vibration in grinding machine is hard to measure while reversing the table. Such vibration occurs due to impulsive force of table. This vibration further damped by varies means. The vibrations of table of hydraulic grinding machine are minimizing by controlling the speed and pressure of fluid. Vibration occurs when a system is displaced from a position of stable equilibrium. The system returns to equilibrium position under the action of restoring forces (such as the elastic forces, as for a mass attached to a spring, or gravitational forces, as for a simple pendulum). The system keeps moving back and forth across its position of equilibrium. A system is a combination of elements intended to act together to accomplish an objective. Vibration in grinding machine is hard to measure. It is observed from the formation of waviness on the work piece and grinding wheel. The major causes of vibration in grinding machine are misalignment and unbalancing. These unwanted vibrations will reduce the life of both machine and tool, resulting in loss of production. Vibration measurement is done by different approaches. This paper explains the vibration measurement done by vibrometer. The vibrations are minimized by introducing dampers, made of rubber and springs. The vibration is isolated due to the elasticity and energy absorbing property of rubber. The vibrations of table of hydraulic grinding machine are minimizing by controlling the speed and pressure of fluid.
