A horizontal guide on the front wall carries a tool turret carrying a tool and shiftable along the horizontal guide between one position aligned with the axis of one of the spindles and another position aligned with the axis of the other of the spindles. A conveyor transports unmachined workpieces into the lower stations and machined workpieces out of the lower stations. Respective actuators shift the spindle units vertically along the respective axis between the lower stations and the upper stations. | 02-21-2013 |
20130087026 | METHOD FOR CONTROLLING COMBINED LATHE APPARATUS, COMBINED LATHE APPARATUS, TURNING TOOL HOLDER, BLADE POSITION REGISTERING APPARATUS, AND BLADE POSITION DETECTING APPARATUS - A carriage is moved in a direction including a Y axis component in order to move a turning process tool that is attached to a tool spindle along a horizontal line that is perpendicular to a Z axis, and thus, a turning process is carried out on a workpiece which is attached to a workpiece spindle. | 04-11-2013 |
20130133488 | APPARATUS FOR MACHINING SHAFT-SHAPED WORKPIECES - A machining apparatus for a shaft-type workpiece has a housing or frame defining a pair of spaced and upright side walls and a vertical front wall bridging the side walls. Vertical guides on one of the side walls carry a vertically shiftable headstock and tailstock capable of rotating a workpiece about an upright axis. Horizontal guides on the front wall carry a turret adapted to hold first machining tools and horizontally shiftable for engagement of the first tools with a workpiece held and rotated by the headstock and tailstock. A holder on the other of the side walls can hold a workpiece with an end of the workpiece exposed so that a second tool can engage and machine the exposed end of the workpiece. | 05-30-2013 |
20130276600 | LATHE MACHINE FOR INTERNAL BORE PROCESSING - A lathe machine includes a tailstock unit having a bottom seat driven by a saddle of a turret unit to move longitudinally relative to a headstock by means of a first coupler unit, and a tailstock mount mounted on the bottom seat and driven by a turret mount to move transversely by means of a second coupler unit such that a selected one of a centering mandrel and a drilling tool holder disposed on the tailstock mount is in line with a spindle axis of the headstock. A positioning unit includes blocking and abutment members respectively disposed on the bottom seat and the tailstock mount and having rightward- and leftward-facing inclined surfaces which matingly abut against each other to permit the centering mandrel to be kept in line with the spindle axis, thereby rendering the centering process easy and precise. | 10-24-2013 |

The vibration reducing device includes an attenuation inducing member and a pressing and fitting mechanism. The attenuation inducing member is brought into contact with the tool support body so as to generate a frictional force in a direction in which it acts as a resistance to the vibration generated in the tool support body. The attenuation inducing member has a rigidity in a direction conforming to a contact surface between the attenuation inducing member and the tool support body, which rigidity is higher than that of the tool support body. The pressing and fitting mechanism fits the attenuation inducing member to the tool support body in a pressed condition. | 11-26-2015 |
