2. Installation and preparation 2-1 Transportation of the machine When lifting the machine with a crane at the factory site, insert two round bars of about 1-3/8 inch in diameter and use a wire suspension rope of sufficient strength to bear a load of 6,600 lbs.
2-2 Inspection and cleaning When the machine is delivered, check for damage or shortages in the number of attachments. Then wipe off dirt and protective coating. 2-3 Storage and installation The surrounding condition of storage is that Temperature range: -25 °c to +75 °C Relative humidity range: 30% to 95 % (non-condensing) Damage from shock and vibration should be avoided Ingress of solid bodies and liquid should be avoided...
2-5 Cutting oil There are two general types of cutting oil, i.e., water-soluble cutting oil and water-insoluble cutting oil, and these are further divided into many groups. As selection of the cutting oil depends on each cutting condition, particular trade names or groups cannot be specified here but it is necessary to observe the following: (1) Use of water-insoluble cutting oil.
3. Handling the main operating parts 3-1 Name of each part Fig. 6 Fig. 7 Draw-in blot (1) Main spindle vertical rapid lever Name plate for indicating (2) Spindle quill clamping lever spindle speed. Hand wheel for main spindle (3) Main spindle vertical adjustment vertical feed.
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.
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)).
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)).
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...
3-10 Vertical spindle quill clamping The spindle quill clamp lever (2) (Fig.7) should be clamped the quill when turned to the right and release the quill when turned to the left. 3-11 Fine reading device for main spindle vertical movement When accuracy is required in vertical feed, the micrometer (Fig.15 (1)) should be clamped to the indicator holder (Fig.15 (2)) with the clamping screw (Fig.15 (3)),and the indicator stopper (Fig.15 (4)) should be fixed at a suitable height by the fixing knob (Fig.15...
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.
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.
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.
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.
4. Safety devices 4-1 Thermal relay When electric current exceeding the rating, the thermal relay (Fig.21) is actuated automatically to stop the driving motor. If the thermal relay is actuated, locate and correct the cause and reset the thermal relay by pressing the thermal relay reset push button. 4-2 Fuses Fuses (Fig.21) are installed in the control box to protect electric circuits.
