Abstract
A cutting fluid tank includes a variable flow restricting device configured to restrict a flow of cutting fluid containing chips into an interior of a tank body configured to store the cutting fluid containing the chips flowed from a work portion of a machine tool. The variable flow restricting device includes variable partitioning members which constitute at least part of a partitioning that partitions a flow channel of the cutting fluid containing the chips. The variable partitioning member is pivotably and the flow channel varies in association with the pivotal motion of the variable partitioning member.
Claims11
A cutting fluid tank comprising:
- a tank body having stored therein cutting fluid containing chips, the cutting fluid containing the chips discharged from a work portion of a machine tool and flowed into an interior of the tank body at a predetermined inflow position;
- a cutting fluid supply device provided in the interior of the tank body and configured to supply the cutting fluid in the interior of the tank body toward the work portion of the machine tool;
- a variable flow channel configured for a flow of cutting fluid containing chips, wherein the flow has a velocity that makes the chips preventable from accumulating on a bottom portion of the tank body;
- and
- a variable flow restricting device provided in the interior of the tank body and configured to restrict a flow of the cutting fluid containing the chips from the inflow position to the cutting fluid supply device and to be capable of varying at least one of a direction and a position of the variable flow restricting device with time, the variable flow restricting device configured to be capable of varying the area of the variable flow channel with time.
