The Drilling and Milling Feed
The drilling and milling feeds are performed manually.
• For the vertical directions of drilling and milling, there is a fine-feed mechanism. Pull out the
Clutch Handle (5) (Fig. 8) and turn the Drilling/Milling Feed Handle (3) to achieve quick feed.
• Push in the Clutch Handle (5) (Fig. 9) and use the Fine-Feed Handle (6) for fine-feed
applications (Fig. 10)
Longitudinal and Transverse Feeds
• Turn the Longitudinal Handle Wheel (16) to perform left-right feed motions of lower slide.
• Turn the Transverse Wheel (9) to perform frontward-backward feed motions of the bench.
Note:
The control numbers given below in parentheses refer to Fig. 5 in the Controls section above.
The Tailstock
As shown in Fig. 11, the tailstock (on the right) can provide support to a workpiece from the
right side. It can move along the bed and stop at any position providing support to the center,
drill, reamer, tapping head or other tools.
• After loosening the Handle for Locking Tailstock (15), the tailstock can be moved to the left or
right. After positioning the tailstock, it should be relocked with the handle.
• After loosening the Tailstock Quill Lock Handle (12), the forward and backward functions of
the quill can be performed by turning the Tailstock Hand Wheel (13). After positioning the
Tailstock Quill, it should be relocked with the handle.
ATTENTION:
When the speed of spindle is too high, a live center should be used.
The Tool Post
The compound tool post mounted on the bench (Fig. 12) can be rotated to an angle with the
turning axis for machining a bevel face or cone surface. The graduations on the front of the
base of the tool post are from left 60º to right 60º.
• By turning the Tool Post Handle Wheel (10), fine feed can be achieved.
• By rotating the Handle for Locking Tool Post (8) counter-clockwise, the upper section of the
compound tool post can be moved to the right and the lower section can be used as a bench
clamp (as in Fig.13).
• When clamping the workpiece with the bench clamp, the locking lever in the accessories (#10
in Fig. 1) can be used for clamping or releasing the workpiece by inserting the rod into the
round hole of Tool Post Handle Wheel (10).
Changing the Speed of the Drilling/Milling Spindle
WARNING:
Put the power switches in the off positions before making any adjustments or changing
accessories. Such preventive safety measures reduce the risk of starting the machine
accidentally.
The speed of Drilling/Milling Spindle is changed by adjusting the belt pulley.
• When using 220V power, the speed is 5 steps of 430 – 2000 RPM
• When using 110V power, the speed is 4 steps of 430 – 1500 RPM.
Refer to the speed plate on the drilling/milling box cover. (as shown in Fig. 14)
Loosening the middle pushing bolt and the fixing bolt of the motor (as shown in Fig. 15) allows
shifting the position of the belt to change the speed.
After shifting the belt position, retighten the pushing bolt and the motor fixing bolt in turn.
