Patent number: 11090776Abstract: An automatic tool changer includes a cover that partitions a machining area and a non-machining area, and an opening/closing member that opens/closes an opening of the cover by turning in synchronization with rotation of a tool changer magazine. The opening/closing member includes a plate section partitions the machining area and the non-machining area at a position of the opening of the cover. In a case where the tool changer magazine performs tool replacement with respect to a tool storage magazine, the plate section closes the opening of the cover by taking a horizontal posture. In a case where the tool changer magazine performs tool replacement with respect to a main spindle, the plate section opens the opening of the cover by changing its posture from the horizontal posture to an inclined posture or a vertical posture.Type: GrantFiled: November 15, 2017Date of Patent: August 17, 2021Assignee: HORKOS CORPInventors: Hiroaki Kiso, Kunihiro Ikeda

Patent number: 7367756Abstract: In adjusting phase for work (W), the operation of mounting/dismounting a reference tool on a spindle (6) is dispensed with and so is a storage space for the reference tool, and besides, it is arranged that the thrust on the work (W) does not directly act on the spindle (6) at the time of this phase adjustment. In a machine tool in which a spindle housing (7) supporting the specifically directed spindle (6) for rotation alone is supported for parallel motion in orthogonal three-axis directions (XYZ) by a numerical control mechanism (4), in determining the phase for the work (W) is feed-rotated around a specific axis (S), it is arranged that with a reference block (9) fixed to the spindle housing (7), the work (W) is feed-rotated around the specific axis (S) to abut the phase reference section (W1) of the work against the reference block (9), so as to find the amount of feed-rotation of the work at the time of this abutment.Type: GrantFiled: October 22, 2003Date of Patent: May 6, 2008Assignee: Horkos CorpInventors: Shinsuke Sugata, Tadashi Makayama
