Abstract
Provided is a cutting fluid tank for a machine tool, with which the operator's time and effort for cleaning are reduced and the maintainability is enhanced, without entailing an increase in size. In a tank body, a cutting fluid flow channel having a spiral shape and extending from a tank center region to a tank outer peripheral region is formed by a flow channel forming plate. An inflow port into which a cutting fluid from inside a machining chamber flows is provided at an outer peripheral region of the lid, whereas an outflow port to take out the cutting fluid in the tank body to an outside is provided at a center region of the lid. A pump to pump up and supply the cutting fluid to the machining chamber is provided at the outflow port.
Claims8
A cutting fluid tank for a machine tool, comprising:
- a tank body having a bottom wall that is substantially rectangular in plan view, and four side walls extending upward from a peripheral edge of the bottom wall;
- and a lid that closes an upward opening of the tank body, wherein
- in the tank body, a cutting fluid flow channel having a spiral shape and extending from a tank center region to a tank outer peripheral region is formed by a flow channel forming plate having a spiral part,
- an inflow port into which a cutting fluid from inside a machining chamber flows is provided at a center region of the lid, whereas an outflow port configured to take out the cutting fluid in the tank body to an outside is provided at an outer peripheral region of the lid, and
- a pump configured to pump up and supply the cutting fluid to the machining chamber is provided at the outflow port,
- wherein, the flow channel forming plate has, as components of an outermost peripheral region:
- a first corner portion provided at a corner region sandwiched between a first side wall and a second side wall;
- a second corner portion provided at a corner region sandwiched between the second side wall and a third wall;
- a third corner portion provided at a corner region sandwiched between the third wall and front a side wall;
- and the outflow port is provided at a fourth corner portion sandwiched between the front side wall and the first side wall.
