Description

  The present invention is a compact and movable magnet fixed type for processing the upper surface of a pedestal board on which a mold is placed, for example, with a finishing accuracy in the range of about 3/100 of 1 mm, mainly in forging presses, sheet metal presses and the like. The present invention relates to compact milling and mobile machining.

  As a conventional magnet-fixed milling machine, for example, as disclosed in Patent Document 1, a milling unit is provided that can efficiently polish the upper surface of a pedestal board not manually but mechanically. In addition, this device can be freely carried by a truck, etc., and can be easily installed on a pedestal board of a large press machine so that the pedestal board can be efficiently flattened while the milling unit is sequentially moved. Is.

  That is, this milling unit can be mounted so that the base plate is attracted by an electromagnetic magnet to a pedestal board or the like of a press machine, and the horizontal position of the H-shaped frame can be adjusted with respect to the base plate. The saddle member is slidably mounted on the upper surface of the H-shaped frame, and the saddle member can be moved along the longitudinal direction of the frame by rotating the rotating shaft.

The cutter 24 is tightened with a bolt 25, and the cutter 24 can be replaced. If necessary, the entire cutting attachment 15 can be replaced with an attachment for another application.

  As described above, the slide mechanism portion 2 installed on the upper surfaces of the two magnet bases 1 has a lateral width larger than the interval between the outer surfaces of the two magnet bases 1. As shown in FIG. 1 (a), the slide mechanism portion 2 and the left and right magnet bases 1 are placed on the bottom surfaces of the left and right ends of the slide mechanism portion 2 that are extended outward from the magnet bases 1 to each other.
