  • Publication number: 20200221546
    Abstract: Provided is an infrared heating device that appropriately sets positions of infrared lamps and a radiation thermometer relative to an object to be heated and is easily positioned. The infrared heating device includes: an infrared irradiation means that irradiates infrared rays to an object to be heated to heat the object to be heated; a holding member that holds the infrared irradiation means; a radiation thermometer that measures temperature of a surface of the object; and a pair of laser pointers that irradiate laser beams to the surface of the object from different positions. The pair of laser pointers are disposed to cause the respective laser beams to be coincident in position with each other at one point on the surface of the object when a distance between the surface of the object and the infrared irradiation means is a predetermined distance.

  • Publication number: 20150030405
    Abstract: A machine tool includes a machine tool main body, a ram which is supported with respect to the machine tool main body in a movable manner, a main shaft which is supported by the ram in a drivable and rotatable manner, an attachment which can be attached to and detached from a tip end portion of the ram and includes a driving shaft rotated according to rotation of the main shaft and a tool provided on the driving shaft, and a NC device which performs a numerical control based on machining data, and performs machining of a processing target. The control method of a machine tool includes a step of decreasing at least one of a ram overhang amount or a feeding amount when stress applied to the attachment is larger than allowable stress of the attachment based on a machining condition including a diameter, a depth of cut, and a feeding amount of the tool, and information including the ram overhang amount, a shape of the attachment, and a material of the processing target.

  • Publication number: 20120303225
    Abstract: An industrial vehicle 1 includes a brake 5 that applies a driving force or a braking force to a vehicle body 22, a lift pressure sensor 632 that detects pitching vibration of a vehicle body, and a pitching control unit 62 that calculates a pitching control torque for suppressing pitching vibration and generates a pitching control signal for causing the brake 5 to output the pitching control torque. When the industrial vehicle 1 runs under a load, the pitching control unit 62 calculates the pitching control torque based on an output value from the lift pressure sensor 632 to output the pitching control signal. The brake 5 is then driven based on the pitching control signal.
