| 20110098165 | Tool transfer system - A tool transfer system configured to transfer a tool between first and second tool holding devices by causing the first and second tool holding devices to be moved relative to each other. The first tool holding device includes a clamp sleeve forced in a direction toward the second tool holding device so as to be positioned in a clamping position. The second tool holding device includes: a hole defining member defining a receiving hole that is to receive the tool; and a movable engaging member that is movable between a working position and a non-working position depending on movement of the hole defining member. The movable engaging member is engageable with the clamp sleeve, while being positioned in the working position, such that the clamp sleeve can be moved, by engagement of the movable engaging member with the clamp sleeve, so as to be positioned in an unclamping position, during relative axial movement of the first and second tool holding devices toward each other. | 04-28-2011 |
| 20110038680 | TOOL HOLDER FIXING STRUCTURE - A tool holder fixing structure is arranged to fix a tool holder for holding a tool attached with a throwaway tip to a tool-holder holding part of a machine tool so that a foreign-matter receiving clearance is provided between the tool holder and the tool-holder holding part. The foreign-matter receiving clearance is defined in a range of +30° to −30° from a cutting-edge position of the throwaway tip assumed as an original point and in a range of 150° to 210° from the original point, respectively. | 02-17-2011 |
| 20090106961 | Roller burnishing apparatus with pressing-force detecting device - There is disclosed a roller burnishing apparatus including a first member moved relative to an object to be burnished, a second member movable relative to the first member in a relative movement direction, a burnishing roller held by the second member such that the burnishing roller is rotatable, a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction, and a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device. | 04-30-2009 |
