Abstract
A method of supplying cooling water to a laser processing head includes arranging a cooling water supply path connected to the laser processing head, connecting, to the cooling water supply path, a water supply path for supplying water and an antirust supply path for supplying antirust, keeping constant a ratio between a water quantity fed by a water feed means connected to the water supply path and an antirust quantity fed by an antirust feed means connected to the antirust supply path, mixing the water and antirust in the cooling water supply path, and supplying cooling water to the laser processing head.
Claims15
A method of supplying cooling water to a laser processing head, comprising;
- providing a cooling water supply path connected to the laser processing head,
- connecting, to the cooling water supply path, a water supply path for supplying water and an antirust supply path for supplying antirust,
- keeping constant a ratio between a water quantity fed by a water feeder connected to the water supply path and an antirust quantity fed by an antirust feeder connected to the antirust supply path,
- mixing the water and antirust in the cooling water supply path, and
- supplying cooling water to the laser processing head.
A method of supplying cooling water to a laser processing head, comprising;
- providing, in a cooling water supply path connected to the laser processing head, a cooling water tank for storing cooling water,
- connecting, to the cooling water tank, a water supply path for supplying water and an antirust supply path for supplying antirust,
- mixing, in the cooling water tank, water fed by a water feeder connected to the water supply path and antirust fed by an antirust feeder connected to the antirust feed path, adjusting a water feed quantity and/or an antirust feed quantity so that a cooling water conductivity in the cooling water tank comes within a preset range,
- maintaining the cooling water conductivity within the preset range, and
- supplying the cooling water to the laser processing head.
A method of producing laser processing cooling water, comprising;
- connecting, to a cooling water tank for storing cooling water that is a mixture of water and antirust, a water supply path for supplying the water and an antirust supply path for supplying the antirust,
- substantially keeping constant a ratio between a water quantity supplied from the water supply path and an antirust quantity supplied from the antirust supply path, and
- mixing and storing the water and antirust in the cooling water tank.
A method of producing laser processing cooling water, comprising;
- connecting a mixed water supply path to a cooling water tank for storing cooling water that is a mixture of water and antirust,
- connecting, to the mixed water supply path, a water supply path for supplying the water and an antirust supply path for supplying the antirust,
- substantially keeping constant a ratio between a water quantity supplied from the water supply path and an antirust quantity supplied from the antirust supply path,
- mixing the water and antirust in the mixed water supply path, and
- storing the mixed cooling water in the cooling water tank.
A method of producing laser processing cooling water, comprising;
- providing a cooling water tank for storing cooling water that is a mixture of water and antirust, connecting, to the cooling water tank, a water supply path for supplying water and an antirust supply path for supplying the antirust,
- mixing the water supplied from the water supply path and the antirust supplied from the antirust supply path to produce the cooling water,
- measuring a cooling water conductivity in the cooling water tank, and
- adjusting a supply quantity of the water and/or of the antirust to maintain the conductivity within a preset range.
An apparatus for supplying cooling water to a laser processing head, comprising;
- a cooling water supply path connected to a laser processing head,
- a water supply path for supplying water and an antirust supply path for supplying antirust both connected to the cooling water supply path,
- a water feeder connected to the water supply path, and
- an antirust feeder connected to the antirust supply path,
- wherein a ratio between a water feed quantity by the water feeder and an antirust feed quantity by the antirust feeder is substantially kept constant.
