Abstract
PURPOSE: To shorten the correcting grind time of work piece by operating a quantithative fluid supply valve device after a grind-base is moved to a required place trough the operation of a control valve device at time of correcting grind feed.
CONSTITUTION: A quantitative fluid supply valve device 45, which intermittently supplies a fixed amount of fluid, is connected to a cylinder of grind feed cylinder device 37, and a control valve devices (selector valve) 40, 41 are connected between the valve device 45 and the cylinder device 37 to allow a continuous fluid flow into the said cylinder. Furthermore, a detector-device 65 is set to detect that the grind- base is located at a required position short of the dead stop as a feed screw shaft 31 rotates due to the rotation of the cylinder device 37. When correcting grind feed takes place, the grind-base is first moved to the required position mentioned above by the operation of the said control valve device, the operation of the above control valve device is suspended by the detecting signal of the said detector-device 65, and the quantitative fluid supply valve device 45 is to be operated.
