ANALYSIS AND CONTROL OF VIBRATION IN GRINDING MACHINES

Vibration in grinding machine is hard to measure. It is witnessed 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.

the machine while controlling the head of the grinder. A vibration reducing flange (VRF) used to clamp grinding or polishing disks produced mixed results. In some cases it was found to reduce vibration levels by between 1% and 12% on either the support or the throttle handles; but it also caused increases of between 3% and 94% in others. The manufacturer of the VRF claimed to reduce the

Technologies -- Balancing, Acoustic & Vibration Sensors

In recent years, there has been an increase in the rotation speed of grinding machine spindles and in the use of CBN grinding wheels. The reason for this, is to obtain machines that are capable of achieving superior levels of surface finish. With such levels of performance, the vibrations caused by the imbalance of rotating mechanical parts, in particular the grinding wheel support spindle, as

Sources of vibration magnitude data

Reducing vibration exposure by choosing lower vibration models of machine 7 For many machines, there is scope for reducing vibration exposures by avoiding high-vibration models of a machine type. There will always be some range in the vibration magnitudes due to differences in the work activity, the operators' techniques, and the condition of the tool etc. The greater the difference between

Vibration & Chatter Control of Machinery

We are typically commissioned to carry out surveys of floor vibration levels at the proposed sites of installation of grinding machines, coordinate measuring machines and sensitive measuring instruments such as speckle pattern interferometers. We have also been consulted about the likely isolation systems required when mounting service plant machines such as chillers, onto the roofs of new

Analysis and control of vibration in grinding machines

26/08/2014· Floor vibration is also a source of vibration. 1.2.2 Self Excited Vibration These vibrations are caused from the cutting process in grinding machines. Regenerating effect is the main cause of this vibration. On the rotation of the grinding wheel, there is the chance of formation of waviness between the grinding wheel and workpeice. A characteristic feature of grinding chatter is,

A primary function of the system is to warn of the presence of chatter and other abnormal vibrations while grinding. It is particularly applicable to machines that are not always continuously manned as it records a vibration history for the roll and also computes a cumulative Roll Quality Index (RQI) which provides a simple indication of the likelihood of the presence of chatter marks in the

Hand arm vibration Worried about your hands?

Hand Arm Vibration Syndrome (HAVS) caused by exposure to vibration at work is preventable, but once the damage is done it is permanent. The Control of Vibration at Work Regulations 2005 were introduced to better protect workers from vibration at work and came into force in July 2005. Am I at risk? You are at risk if you regularly use hand-held or handguided power tools and machines such as
