3-4 The tapping function of the vertical spindle Steps to operate the tapping function: Turn button (Fig.8 (2)) to the right, and pull the tapping control lever (Fig.9) up for release (Counter-clock-wise), down for tapping (Clock-wise). Fig. 9 3-5 Change of vertical spindle speed The vertical spindle speed should be chosen according to work piece material, cutter diameter and cutter material tables 5 and 6 for you reference. -
Page 15: Change Of Horizontal Spindle Speed
3-6 Change of horizontal spindle speed Move lever (Fig.10 (1)) to position depending upon the spindle speed range required, and move lever (Fig.10 (2)) to the position of the particular speed required. Speed changes must not be made while the main motor is running. To facilitate changing spindle speed, stop main motor by depressing horizontal spindle stop button (Fig.8 (5)). -
Page 16: Vertical Spindle Manual Feed Operation
3-7 Vertical spindle manual feed operation There are two types of manual vertical spindle adjustment, namely, adjustment by hand wheel (Fig.11 (1)) and rapid adjustment by the main vertical spindle adjustment lever (Fig.12 (4)). For general milling, the hand wheel for the vertical spindle adjustment should be used. The handle wheel for the vertical spindle adjustment is providing with a scale collar (Fig.12 (2)). -
Page 17: Operation Of Vertical Spindle Power Down Feed
3-8 Operation of vertical spindle power down feed The vertical automatic feed should be carried out in the following manner. (1) Stop rotation of the main spindle and align the shifter lever (Fig.13 (1)) with the mark + - on the name plate. (2) Select the necessary feed amount (0.048, 0.096, 0.192mm) per revolution with the vertical feed selection knob (Fig.14 (1)) (3) Set the spindle feed direction lever (Fig.13 (2)) either to the up... -

3-13-1 Swiveling of over arm on horizontal plane The over arm can be swiveled by turning the swivel base (Fig.16 (2)) located on the top of the column. Procedure for horizontal swiveling: (1) Loosen the four bolts (Fig.16 (1)) on the left and right side which secure the swivelbase to the column top. -
Page 21: Operation Of Manual Feed
3-15-1 Operation of manual feed Operate longitudinal feed by hand wheel (Fig.18 (1)), cross feed by hand wheel (Fig.18 (3)), and vertical feed by hand lever (Fig.18 (2)). If directional changing lever (Fig.18 (7)) at central front of saddle is in neutral position, longitudinal manual feed can not be operated. -
Page 22: Operation Of Longitudinal Power Feed
3-15-5 Choice of feed speed Feeding speed is dependent on the spindle speed, material of work piece, tips of cutter and diameter of cutter (Table 6). With this machine, 12 steps of cutting feed and rapid feed are carried out from the feed box which is under the side of saddle. Push the button (Fig.8 (8)) to start the table longitudinal feed motor. -
Page 23: Operation Of Dog
3-15-8 Operation of dog The auto-stop longitudinal feed is worked by dogs which are located in the T-slot front of table. The two fixed dogs (Fig.19 (2) (3)) on the outsides are safety stops which prevent over travel. These should not be moved. The two inside dogs (Fig.19 (4) (5)) can be set at any position so that the table stops automatically in set range. -
