One aspect is a hydraulic ironworker system having a hydraulic ironworker configured with hydraulic power to deliver controlled force to metal workpieces. An accessory tool is coupled to the hydraulic ironworker via a harness assembly and configured to receive the hydraulic power from the hydraulic ironworker. A remote pushbutton assembly is removably coupled to the harness assembly and configured to control hydraulic power from the hydraulic ironworker to the accessory tool and further configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system. A safety plug assembly is configured to alternately couple to the harness assembly in place of the remote pushbutton assembly. Power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies is attached on the harness assembly.

A machine control and data logging station, intended for use with a saw or other machine tool, features a processor which monitors a number of input lines, a real time clock and time stamp function. Any change of input signals from the machine tool will be recorded in flash memory. Both wired and wireless outputs may read the memory at any given time. Optionally, hardware or software data communication encryption may be employed to provide increased confidentiality and security. The station continually monitors sensor inputs and can react automatically to emergency-stop the machine tool upon sensing a dangerous condition.

A machine tool capable of restraining dirt on the footstool and improving setup efficiency. The machine tool includes a machine body having a splash guard surrounding a machining area and a door capable of closing an opening of the splash guard. A footstool is kept mounted on the machine body changeably in place with respect to the machine body. The footstool kept mounted on the machine body is capable of being in a place on an outside of the machine body when the door is closed. The footstool kept mounted on the machine body is capable of being brought to a setup place inside the machining area from the outside of the machine body through the opening when the door is open.

One aspect is a hydraulic ironworker system having a hydraulic ironworker configured with hydraulic power to deliver controlled force to metal workpieces. An accessory tool is coupled to the hydraulic ironworker via a harness assembly and configured to receive the hydraulic power from the hydraulic ironworker. A remote pushbutton assembly is selectively coupled to the harness assembly and configured to control hydraulic power from the hydraulic ironworker to the accessory tool and further configured with an emergency stop button that, when actuated, disables all power to the hydraulic ironworker system. A safety plug assembly is configured to alternately couple to the harness assembly in place of the remote pushbutton assembly. Power to the hydraulic ironworker system is disabled until one of the remote pushbutton and safety plug assemblies are attached on the harness assembly.

A dust suppression assembly is to be fixed on a handheld device. The dust suppression assembly comprises a device interface member having a top end and a bottom end and an intermediate member having a first intermediate end and a second intermediate end, the first intermediate end adapted to be coupled with the bottom end of the device interface member. Further, the device interface member is having a first channel and the intermediate member is having a second channel, the first channel and second channel joins to form a passage for supplying water to the working end of the tool for suppression of dust, while the handheld device is in use.

Disclosed is a machine tool including: a cover that encloses a processing space in which a workpiece is processed and has a window portion for visual inspection of the processing space from outside; a machining processing unit provided in the processing space; an operation panel for inputting instructions to the machining processing unit, the operation panel being provided outside of the cover; and a cooling system for cooling the machining processing unit, wherein the cooling system includes: a coolant supply unit for supplying a coolant into the processing space; a coolant protection unit that operates to limit adhesion of the coolant to the window portion; and a control unit that switches a state of the coolant protection unit based on a result of detection performed by a sensor for detecting an operator present around the cover. With this machine tool, waste of energy can be suppressed.

A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.

A power tool has a tool holder, an electric motor, a handle, and a main switch for switching on the electric motor. The power tool executes the following control method. The main switch is scanned to see whether it has been actuated. A start inhibitor transmits a blocking signal to a motor controller if the main switch is actuated before the power tool has been connected to the power supply. An activator receives signals from a control unit separate from the electric power tool, compares the received signals with a predefined signature and transmits a release signal to the motor controller if the received signal corresponds to the predefined signature. The motor controller switches on the electric motor in response to actuation of the main switch if the start inhibitor is not transmitting a blocking signal or the activator is transmitting a release signal.

A power tool in one embodiment includes a swing arm assembly movable along a swing path between a first swing arm position and a second swing arm position, a latch pin pivotable between a first position and a second position, an actuator module configured to receive a plurality of actuators, a first actuating module position within the actuator module configured to align a first of the plurality of actuators with a strike plate on the swing arm assembly, a loader configured to bias a second of the plurality of actuators from a second actuating module position within the actuator module toward the first actuating module position, and a control system configured to actuate each of the plurality of actuators positioned in the first actuating module position to force the swing arm assembly away from the first swing arm position and toward the second swing arm position.

The present invention provides a machine tool provided with a cover body having a simple structure, excellent operability, and low manufacturing cost. A tool post movement region one-side-closing cover part (9) for closing a tool post movement region open part (8) is configured so as to be: capable of expanding and contracting in a horizontal movement direction of a tool post (3); arranged facing the tool post (3); elongated by urging means (10) to press against the tool post (3) in a relatively slidable manner and close the tool post movement region open part (8); expanded and contracted by movement of the tool post (3) to hold the tool post movement region open part (8) in a closed state; and provided unconnected to the tool post (3) so that the tool post (3) is relatively slidable with respect to the tool post movement region one-side-closing cover part (9), and the tool post movement region open part (8) is held in a closed state.
