Linear motor operated machine tool

摘要

A linear motor actuated machine tool includes a bed (1), a column (2), upper and lower X-axis guides (3U,3L), a saddle (4), upper and lower X-axis linear motor magnets, and upper and lower X-axis linear motor coils. Upper and lower X-axis guides are attached to the upper and lower portion of front surface of the column, which is mounted on the bed in the vertical direction, in the horizontal direction. Upper and lower X-axis linear motor magnets are fixed on the front surface of the column at upper side and lower side of the upper and lower X-axis guides in the direction of X-axis with making pole surfaces thereof face to frontward. Upper and lower X-axis linear motor coils are fixed to upper end and lower end of the rear surface of the saddle, which is mounted on the front surface of the column with being guided by upper and lower X-axis guides and having a through space (11) at the center portion thereof, with opposing to upper and lower X-axis linear motor.
