A needle screw fitted to a compressed fluid supply part that is provided on a nozzle main body of a dust removing device adjusts the jet flow rate of a first compressed fluid from a jet nozzle by adjusting the flow path area of a first fluid supply path. Meanwhile, the suction flow rate of a second compressed fluid to be discharged into a discharge flow path is adjusted by adjusting the flow path area of a second fluid supply path by turning a nozzle main body-side adjustment screw that is provided on the nozzle main body and a suction nozzle-side adjustment screw that is provided on a suction nozzle.

A machine tool chip removal device including a coupling interface to couple with a rotatable spindle of a machine tool to facilitate rotation of the machine tool chip removal device about an axis at a rotational speed. The chip removal device can also include a main fluid channel with an opening to receive pressurized fluid from the machine tool. The chip removal device can further include a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions. Each fluid delivery channel can be in fluid communication with the main fluid channel. In addition, the chip removal device can include one or more valves associated with the first and second fluid delivery channels to selectively allow fluid passage from the main fluid channel to the fluid delivery channels. The one or more valves can be actuated by varying fluid pressure and/or rotational speed.

The present invention discloses a scrap removing device for cutting a wheel rim which comprises a main body having a working surface, a wheel rim positioning member, a first blowing member and a second blowing member sequentially disposed on the working surface from a top side thereof.

Provided is a cleaning apparatus for cleaning a portion where a seating pad contacts or a hole into which a pin is inserted when a workpiece is placed. The cleaning apparatus for cleaning a workpiece having a placing portion and a reference hole, including: a table plate, a seating pad on which the workpiece is placed at the placing portion, a first nozzle that ejects a cleaning fluid, a pin inserted into the reference hole, and a second nozzle that ejects the cleaning fluid toward inside of the reference hole.

A processing apparatus includes a chuck table having a holding surface for holding a workpiece; a horizontal moving mechanism that moves the chuck table in a horizontal direction and is supplied with a first oil; and a vertical moving mechanism that moves a processing unit in a vertical direction and is supplied with a second oil. Before mounting the workpiece on the holding surface, the holding surface is imaged by a camera while being irradiated with light, and it is examined whether or not the picked-up image is emitting light. If there is a light-emitting part in the picked-up image, it is determined that oil is adhered to the light-emitting part.

A liquid temperature adjustment apparatus 1 includes: a refrigeration device 10 which includes a refrigeration circuit 16 in which a compressor 11, a condenser 12, a first expansion valve 13, and a first evaporator 14 are connected in this order by a pipe to circulate a heat medium and an injection circuit 17 which branches from a portion downstream of the compressor 11 and upstream of the condenser 12 in the refrigeration circuit 16 and is connected to a portion downstream of the first expansion valve 13 and upstream of the first evaporator 14; and a first liquid supply device 100 which circulates a first liquid. The injection circuit 17 includes a flowrate adjustment valve 17A which adjusts a flowrate of the circulated heat medium. Further, the first liquid circulated by the first liquid supply device 100 is cooled by the first evaporator 14.

An air-blowing method includes the steps of blowing, inside a machine tool, air onto a workpiece after machining, issuing a workpiece pick-up advance notice signal for notifying beforehand of pick-up of the workpiece by a robot or a worker, on the basis of a task state of the robot or an operation of the worker, and calculating the additional time for air blow on the basis of a time required by the robot or the worker to arrive at a workpiece pick-up position in front of the machine tool after the workpiece pick-up advance notice signal is issued, where air blow is extended by just the additional time in the step of blowing air.

A cleaning apparatus includes a suction pipe, a suction nose located at a distal end of the suction pipe, an exhauster connected to the suction pipe, a compressed air feeder, and a lance. The suction nose includes a suction port at a distal end thereof. The suction nose holds the suction port in a manner retractable along an axis of the suction pipe. The lance has a distal end extending along the axis of the suction pipe inside the suction pipe. The lance has an orifice obliquely extending toward a basal end of the lance.

A coolant supply device 1 includes a coolant tank 2 storing coolant therein, a mounting member 14 covering a part of an upper opening of the coolant tank 2, and supply pumps 32, 33, 34 mounted to the mounting member 14 and configured to pump up coolant C from the coolant tank 2 and supply the pumped-up coolant C to predetermined destinations. The coolant supply device 1 is configured such that the coolant C supplied to the predetermined destinations by the supply pumps 33, 34 is returned to the coolant tank 2. The mounting member 14 is supported by support members 16, 17, 18 such that it is slidable to a non-covered side of the upper opening of the coolant tank 2.
