Abstract: A coolant processing apparatus removes sludge from a coolant discharged from a machine tool. The coolant processing apparatus includes a first reservoir and a second reservoir provided in a tank for retaining the coolant. The first reservoir includes a flow path in which the discharged coolant flows, and a portion downstream of the flow path to retain the coolant such that the sludge remains in the first reservoir. The flow path has at least one bend to bend a flow of the coolant at least once in a horizontal direction. The second reservoir retains the coolant flowing out from the first reservoir. A boundary wall is provided between the first and second reservoirs, at a location downstream of the at least one bend of the flow path, and has such a height that allows a supernatant of the coolant in the first reservoir to flow into the second reservoir.

Abstract: A method for producing a three-dimensional shaped product that employs a shaping method based on dispersion of powder by a squeegee and irradiation onto a powder layer with a laser beam or electron beam, includes the following steps: 1. Setting an upper limit value and lower limit value for the amount of circulation passing through an anemometer, and an adjusting value within this range; 2. Measuring the amount of circulation and effecting control as follows: (1) When the measured value is between the upper limit value and lower limit value, the rotational speed of the blower fan is maintained, and (2) When the measured value has fallen below the lower limit value due to clogging of a filter, the rotational speed of the fan is increased and the rotational speed is selected at the stage where the measured value has reached the adjusting value, and the rotational speed is maintained.

Abstract: A shaping method for a three-dimensional shaped product, including the following steps: 1. Setting a traveling distance of the squeegee to be a short distance that does not reach a chamber wall section, 2. Establishing location of wall layers connecting both ends at the chamber wall sections in a direction perpendicular to the traveling direction of the squeegee, within a traveling range based on the set traveling distance, or connecting to the ends on a powder feeder side at inner side of the chamber wall sections by a region to be sintered, from both sides of the region, 3. Forming powder layers by movement of the squeegee over the set traveling distance, 4. Forming sintered layers by irradiation with a beam on the formed powder layers, and forming wall layers by irradiation with a beam at the locations of the established wall layers, 5. Repeating steps 3 and 4.
