A method for machining a workpiece includes using a multi-axis robot to lift a tool head from a magazine. The robot attaches the tool head to an end of a drill tube. The drill tube is then rotated and longitudinally translated to machine the workpiece. The tool head is withdrawn from the machined workpiece longitudinally by moving the drill tube. The robot is used to disconnect the tool head, replace the disconnected tool head into a magazine and withdraw a different tool head from the magazine for attachment to the drill tube.

Control method for a dust extraction module (2) for a chiseling tool (5), including the following steps: using a fan (18) of the dust extraction module (2) to draw in an air flow Q from a certain place of a substrate (31) being worked by the tool (5), using a material detector (24) to identify the material M at the place of the substrate being worked by the tool (5), and adapting the suction power of the dust extraction module (2) as a function of the identified material M in order to set the air flow Q. The air flow Q is greater than or equal to a rated value Qo in the case of an iron-free mineral material M1, whereas the air flow Q is less than the rated value Qo in the case of a material M2 containing iron.

Provided is a lifetime prediction device and a machine tool that enable simple prediction of the lifetime of a filter while suppressing a prediction error with respect to a true value. A lifetime prediction device (88) according to one embodiment is provided with: a pressure acquisition unit (90) that acquires in time series a pressure value of a liquid applied to a filter (52); a time acquisition unit (92) that acquires processing time of a designated process; a calculation unit (94) that calculates the amount of pressure change during the processing time; and a prediction unit (96) that predicts a lifetime period before an upper limit value of the pressure of the liquid applied to the filter (52) is reached, by using the pressure value, the processing time, and the pressure change amount at the time of completion of the designated process.

This abnormality detection device: causes a motor that drives a drive unit at a plurality of rotational speeds to perform a detection operation based on a command for diagnosing the state of the drive unit, acquires, as information indicating the operating state of the drive unit, a control command for the motor driving the drive unit or a feedback signal from the motor driving the drive unit, during the detection operation; analyzes the control instruction for the motor driving the drive unit or the feedback signal from the motor; determines the state of the drive unit based on the result of the analysis, and notifies, based on the determination result, that the state of the drive unit is different from that in normal time.

A lower drill tool that is structurally configured to receive a bracket, and, to cooperate with an upper drill tool having a pair of spaced apart drill bits. The lower drill tool has part receiving surface, a pair of spaced apart drill bores, a central bore, a centering nub and a biasing member. The drill bores extend downwardly away from the part receiving surface. The central bore is between the drill bores and extends downwardly away from the part receiving surface. The centering nub is slidable within the central bore, and has an upper tip extendable beyond the part receiving surface, positionable between an extended position and a partially retracted position. The upper tip has a conical configuration. The biasing member is positioned within the central bore and biases the centering nub toward the extended position. A drill system and a method are also disclosed.

A system can include a heatset steam tunnel extending along a longitudinal axis. The heatset steam tunnel can have an inlet/outlet structure, the inlet/outlet structure extending along a horizontal axis that is perpendicular to the longitudinal axis and a vertical axis that is perpendicular to the horizontal axis and the longitudinal axis. An operator space positioned adjacent the inlet/outlet structure of the heatset steam tunnel. A guard can at least partially covering the inlet/outlet structure. The guard can comprise a transparent window material. The guard can be configured to direct steam from the inlet/outlet structure of the heatset steam tunnel away from the operator space while permitting viewing into the inlet/outlet structure from the operator space.
