Processing method for internal surface of cylinder and processing equipment

摘要: PROBLEM TO BE SOLVED: To lessen machining allowance at low grinding-efficiency portions on the internal face of a cylinder in process honing, without extending processing time. SOLUTION: In pneumatic/hydraulic pressure converter unit 29 within head 13, pneumatic is converted into hydraulic pressure, and by power 45, which works, transfer 57 an elastic deformation portion 43 shifts to such direction as form orthogonal angle with axis, jointly boring bar 59, equipped roughing blade 61 finishing 63. state applied 45 so that protruded toward inner bore 67, 13 transferred outward movement thereby carried out. After completion roughing, application once lifted, subsequently, resumed gradually increased, 63 from inner-radius direction, moved through return course opening other side finish-machined taper shape. processing, finish implemented, kept constant level.
