Abstract: A machining apparatus includes a processor configured to control an actuator to move a tailstock in a first direction at a first speed, to detect a contact between the tailstock and a workpiece based on a change in an input amount to the actuator while the actuator is controlled to move the tailstock at the first speed, to control the actuator to stop moving the tailstock when the contact is detected, to control the actuator to move the tailstock by a first distance in a second direction, to control the actuator to move the tailstock in the first direction at a second speed lower than the first speed, and to control the actuator to stop moving the tailstock, when the input amount to the actuator becomes a value corresponding to the target pressing force while the actuator is controlled to move the tailstock at the second speed.

Abstract: The invention provides a vertical turret lathe capable of preventing an inner diameter turning tool attached to a turret tool rest from interfering with a workpiece during machining of the outer diameter of the workpiece. The vertical turret lathe comprises a work table that holds a workpiece W1 and rotates, and a working head 40 having a turret tool rest 50 and capable of moving in X-axis and Z-axis directions. A tool holder 70 for holding an inner diameter turning tool T2 via hydraulic pressure is attached to a part of the tool supporting portions 60 of the turret tool rest. The automatic tool changer apparatus 100 includes a turret-type tool magazine 120 and pistons 160 and 162, which mechanically press the pins 74 and 76 of the tool holder 70 and clamp or unclamp the tool T2.

Abstract: The invention provides a downsized processing machine, equipped with a machine tool and a multijoint robot. The processing machine 100 comprises a machine tool 10, a workpiece pallet 70 and a gantry rail 120 disposed above the machine tool 10. A multijoint robot 130 traveling on the gantry rail 120 is equipped with a dual-partitioning electron system speed monitoring function. Through use of this function, the range of movement D2 of the multijoint robot 130 is controlled to fit within the inner side of a front cover 11 of the machine tool 10, according to which the safety barrier 180 can be downsized. This arrangement enables the operator to open or close a door 12 of the machine tool 10 and to manipulate a control panel 16 even when the multijoint robot is in operation, and the footprint of the machine can be minimized.

Abstract: A multitasking workpiece machining apparatus includes a pair of workpiece support devices supporting an elongated workpiece, first and second headstocks at positions outside of the workpiece support devices. The second headstock is capable of moving closer to and apart from the first headstock. Each workpiece support device respectively includes a travel drive device traveling between the first and second headstocks. A numerical control unit controls travel of each workpiece support device by synchronously controlling each travel drive device.
