Title:
CUTTING DEVICE
Document Type and Number:
Japanese Patent JP2018075690
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cutting device which can automatically perform positioning of a table in a longitudinal direction with high accuracy.SOLUTION: A cutting device having: a cutting grindstone 30 which cuts a work-piece W; a table 10 which supports the work-piece W, and which is driven by a wire or belt 58 to be horizontally moved; a motor 51 which moves the table 10 via the wire or belt 58; and a control unit 40 which controls the motor 51 thereby controlling movement of the table 10. The control unit 40 stops or inverts movement of the table 10 after controlling a movement speed of the table 10 to a prescribed stop preparation speed. Thus, an inertial force is reduced when stopping or inverting is reduced so as to suppress suppressing elongation or slackening of the belt 58 and so on, whereby excessive movement of the table 10 can be suppressed. As a result, accuracy of a stop or inversion position can be improved.SELECTED DRAWING: Figure 3
