Fixed temperature water supplying device

Abstract

The invention provides a fixed temperature water supplying device. Damage of a driving part is avoided and time for exchange work of cooling water and shutdown time are greatly reduced. The fixed temperature water supplying device (1) comprises a first storage container (11) for storing water used for processing, a first flow path (12) for providing water of the first storage container for a processing device (3), a water temperature adjusting unit (16) for adjusting water temperature in the first flow path, a second storage container (21) for storing water used for cooling a driving part, a second flow path (22) for providing water of the second storage container for the driving part (4), a circulation flow path (23) for returning water for cooling the driving part from the driving part to the second storage container, a fixed temperature water supplying flow path (31) for providing water with adjusted temperature for the second storage container from the first flow path, and a water drainage flow path (32) for draining water in the second storage container to the outside. By providing water for the second storage container from the first flow path and draining water from the second storage container, water in the second storage container is exchanged.

Description

technical field [0001] The present invention relates to a constant temperature water supply device which adjusts the temperature of water from a water supply source to a processing device. Background technique [0002] Generally, in a processing device such as a grinding device or a cutting device, the water temperature of the processing water, the cooling water of the main shaft, and the like is managed to a constant temperature. The supply of machining water and cooling water at a constant temperature prevents deterioration of machining accuracy due to thermal expansion and contraction of mechanical parts, and prevents damage to the device itself due to contact between parts such as spindle seizure. Conventionally, a constant-temperature water supply device is known that maintains water supplied to a processing device at a constant temperature (for example, refer to Patent Document 1). A temperature regulator is installed in the middle of the flow path from the storage co...

AI Technical Summary

Problems solved by technology

In this case, when the cooling water is used continuously for a long time without replacing the processing water, the impurities are concentrated and accumulated in the pipes etc. Worry about the damage of the part

In addition, when replacing the cooling water of the drive unit, it is necessary to stop the operation of the processing device, so there is a problem of downtime.
