How to measure the vibration of a numerical control drill machine

May 28, 2018

The dynamic force of the vibration to the numerical control drilling machine makes the dynamic displacement of the NC drilling machine will affect its performance. At the same time, the dynamic stress will cause the fatigue damage, sometimes leave the residual deformation, reduce the service life of the equipment, and produce the noise of the environment, so it is necessary to measure the vibration of the numerical control drilling machine, so that the number of the numerical control drilling machines should be measured. How does a control drill press measure the vibration?

The steps of measuring the vibration of a numerical control drilling machine are as follows:

1. Measurement of the vibration quantity: measuring the size of the displacement, velocity and acceleration of the vibrating body at the selected point; the time history, frequency, phase and spectrum of the vibrator; the excitation is zero.

2. Test of system characteristic parameters: stiffness, damping, natural frequency, mode of vibration, and dynamic response characteristics of the system.

3. The dynamic strength test of mechanical, structure or components: vibration or impact test on the mechanical simulation environment conditions to test the life of the products, the stability of the performance, and the rationality of the design, manufacture and installation.

4. Vibration monitoring of equipment, equipment or operating machinery: on-line monitoring of equipment, equipment or operating machinery, measurement of vibration information at any time, diagnosis of fault, and timely processing to ensure its normal and reliable operation.

In order to ensure the working performance and service life of the CNC drilling machine, we should control the vibration of the NC drilling machine within the allowable amount by measuring the vibration of the equipment.
