Title: Surface grinder movement control circuit - has sensors to detect motion in both longitudinal and transverse directions with switches for electro-hydraulic valves
Inventor: ARTEMIEV VLADIMIR ILLARIONOVIT
IPC: B24B49/00
Filed: 1978-09-28
Abstract: One drive control of the grinding machine regulates the longitudinal and the other the transverse movements. Each control circuit incorporates similar elements. The transverse movement is picked up by a sensor, with inputs to a switch unit. Outputs from the latter supply power amplifiers for an electrohydraulic control valve coupled with a force developing hydraulic cylinder. The switch unit also receives a signal from the main drive motor through an additional sensor and a delay unit. There is a control switch arrangement which may use an electronic circuit instead of the electrohydraulic valve. In this case the two switch outputs combine signals from both longitudinal and transverse units through a logic circuit with OR gates and a power amplifier. The gate elements may be controlled by external selectors to determine a required profile cutting pattern.
