surface grinder of operation and adjustment

Taking M7120D surface grinder as an example, this paper introduces the use of surface grinder.

1. Names and functions of various parts of horizontal axis surface grinder with rectangular table

M7120D surface grinder is a horizontal axis surface grinder with rectangular table, which is composed of bed 1, worktable 2, grinding head 3, slide plate 4, slide plate 4, slide plate 3, slide plate 3, slide plate 3, slide plate 3, slide plate 3, slide plate 3, slide plate 3, slide plate 4, slide plate 3, slide plate 4, slide plate 4, slide plate

(1) The bed 1 is a box casting with V-shaped guide rail and flat guide rail, and the worktable 2 is installed on the guide rail. The hydraulic control box 9 in the front of the bed is equipped with a worktable manual mechanism, a vertical feed mechanism, a hydraulic control board, etc., which are used to control the mechanical and hydraulic transmission of the machine tool. An electric control button is arranged on the electric button board 8.

(2) Worktable worktable 2 is a basin shaped casting with a rectangular worktable on the upper part and a protruding guide rail on the lower part.

The upper surface of the worktable is ground and has a T-shaped groove to fix the work object and the electromagnetic sucker 7. A protective cover is installed around the table to prevent the cutting fluid from splashing.

(3) The grinding head 3 is installed in the front of the shell with two sets of short three block oil film sliding bearings and two sets of spherical thrust bearings to control the axial movement. The motor rotor is installed at the tail of the spindle, and the motor stator is fixed on the shell.

The grinding head 3 has two feeding forms on the horizontal swallow tail guide rail, one is intermittent feeding, that is, the worktable changes direction once, the grinding wheel grinding head makes a intermittent feeding horizontally, the feed rate is 1-12mm, the other is continuous feeding, the grinding head moves back and forth continuously on the horizontal swallow tail guide rail, and the continuous moving speed is 0.3-3m / min. it is controlled by the feed selection knob. In addition to hydraulic transmission, the grinding head can also be fed manually.

(4) Slide plate 4 has two sets of mutually vertical guide rails, one is vertical rectangular guide rail for vertical movement along the column, the other is horizontal dovetail guide rail for horizontal movement of grinding head.

(5) The column 5 is a box with two rectangular guide rails at the front. The lead screw is installed in the middle, and the slide plate moves vertically along the rectangular guide rail through the nut.

(6) The M7120D surface grinder with electrical box is improved in the installation of electrical appliances. The original electrical appliances installed on the bed 1 are installed in the electrical box 6, which is conducive to repair and maintenance.

(7) Electromagnetic chuck electromagnetic chuck 7 is mainly used for clamping workpiece.

(8) Electrical button board electrical button board 8 is mainly used for installing various electrical buttons to control the feed movement of the machine tool by operating the buttons.

(9) Hydraulic control box hydraulic control box 9 is mainly used to control the hydraulic transmission of the machine tool.
