Title: Cutting tool
Inventor: OONISHI TAKEHIRO
IPC: B23B51/10
Filed: 1993-05-13
Abstract: PURPOSE:To maintain machining accuracy by removably interposing a spacer, provided with a pair of inside surfaces closely attachable to both side surfaces of a slider and a lock part for preventing separation of the slider from a bottom surface of a recessed groove, so as to easily restore mounting accuracy and position accuracy of the slider. CONSTITUTION:Spacers 12, 13 are removably interposed between both side surfaces of a slider 15 and a wall surface of a recessed groove 11 in which the slider 15 is slid, and since a cutting load, acting on the slider 15 from a cutting edge tip, is received in the wall surface through these spacers 12, 13, wear and deformation due to such cutting load are generated in the spacers 12, 13. Since wear by sliding the slider 15 is also generated in the spacer, even when such wear and deformation are generated, without reforming the recessed groove 11 and without remanufacturing the slider, machining accuracy by a cutting tool can be very easily and economically maintained by replacing these members.
