The present disclosure provides a bed for use with a turning center assembled with a main shaft housing in which a work piece is chucked, a turret and a tool table configured to process the work piece by a tool, and a transfer apparatus configured to transfer the turret and the tool table. The bed includes: a rib including a plurality of rib elements, in which the rib element includes a first rib element positioned at a lower portion of the bed where the main shaft housing is assembled, and a second rib element positioned at a lower portion of the bed where the transfer apparatus is assembled.
摘要:
A control console of a numerically controlled machine tool having a housing, a screen, at least one circuit board that has electrical components, and a cooling device that includes a cooling channel, through which a fluid can be conducted, the cooling channel extending within the housing between at least two openings in the housing.
摘要:
A method is provided for controlling a power tool (1) when a material (W) is being worked, including the steps: the rotational speed of a drive (20) of the power tool is set to a first value; a first temperature value is measured; the first temperature value is compared to a pre-specified threshold value; the rotational speed of the drive (20) is reduced from the first value to a second value if the first temperature value exceeds the pre-specified threshold value for a pre-specified first period of time; a second temperature value is measured; the second temperature value is compared to the pre-specified threshold value; and the rotational speed of the drive (20) is raised from the second value to the first value if the second temperature value has fallen below the pre-specified threshold value for a pre-specified second period of time.

摘要:
It is an object of the present invention to provide a main shaft lubricating device in which in a machine tool, a temperature variation around a machine is taken into account. A main shaft lubricating device of a machine tool including a temperature sensor for detecting a temperature around a machine, a speed sensor for detecting a rotation speed of a main shaft, supply device for supplying a lubricant oil to a bearing of the main shaft such that a supply amount thereof can be varied, and calculating section for calculating the supply device by the supply device based on an output signals of the temperature sensor and the speed sensor.
摘要:
A method of protecting a rotating device, loaded by temperature of a machine tool with one temperature sensor on that device and a temperature bloc, comprising the steps of inputting specific parameters in the temperature bloc, estimating a value for the device temperature increase caused by the activity of the device and measuring the temperature of the device.
