Manual micro feed: Spindle micro feed needs two steps. First, put the feed rate lever( 5 )in
the “idle” position. Secondly, push button ( SB4 ), then push up the micro feed hand
wheel( 3 ) and make sure that the clutch is engaged, now the micro feed hand wheel could be
turned and micro feed of the spindle works.

Cutting depth control:
For the batch production, you need control cutting depth. A scale in front of spindle box
could meet your requirements. Loosening knurled screw ( 20 ) by turning nob ( 2 ), moving
the scale to the required depth, then fastening the knurled screw( 20 ). Now the machining
depth could be controlled.
7.6 Application of the digital scale:
A small round battery is fixed on the right side position of the spindle box for digital
readout. With this scale, moving distance of the spindle could be easily readout. Except the
battery switch, a “reset” push button and an “English or Metric” converter push button are
available. Cutting depth could be readout at any time and cutting depth could also be set in
advance. This function will be helpful for small batch or single work piece machining.
7.7 Tapping:
Put the “Selection Switch”(17 ) on the tapping position first, turn the feed lever( 4 ) and let
the tap approaches the work piece, a proper manpower force (based on the size of screw)
shall be exerted in order to let the tap comes into the hole. The spindle will be rotated in
reverse when the screw depth is reached, and the tap comes out.
Suppose, tapping job needs stop, push button ( SB4 ) of the hand lever( 4 ) then spindle will
have reverse revolution. and tap returns back.
7.8
Milling
With the requirements and the shapes of the tasks, select the Milling cutter and
accessories, both face mill cutter and end mill cutter can be attached with shank, chuck to the
spindle, after attachments has been attached and clamped, rotate the working table led the
base round pin close to the right hand side of the column, then use latch segments clamp
round pin and set screw, clamp the handle (22) and (23).
For the milling operation, manual feed or auto feed using lever(4 )is not permitted. The
best way is to use micro feed hand wheel(3 ). Lock spindle by turning a clamping rod(7) if
required cutting depth is reached.
