3. Brief description of the driving system and its structure:
The machine consists of spindle box, column, machine base, worktable and its bracket, electric cabinet,
coolant device and machine accessories, total seven component parts. Spindle revolution is main motion of the
machine. During drilling processing, spindle movement along with its axis is a feed motion, spindle box
、
Worktable up and down movement and worktable turn round itself is an auxiliary motion. To those big or
higher work piece that could be clamped on the worktable of the base. The worktable and its bracket should
turn round the column to a proper area far away from the machining area.
Two separately vertical motors realize machine transmission. A special pump supplies coolant water.
Transducer control frequency conversion and realize stepless timing. Two speed segment are made by slippage
gear. Operation lever for slippage and frequency button are located in the front of box, the lever has an idle
position.
The feed rate of speed change could be realized by shifting lever
，
control one group slippage gears realize
three kinds of feed.
Up and down movement of the worktable and spindle is completed by manual. Of cause, little adjustment for
the height of the worktable could also be made by manual.
Two kinds of lubrication, auto or manual, of the machine are available.
Please refer to the diagram 2 for the transmission system of the machine.
For the gear, worm and worm shaft, rack and pinion etc, please see table 1.
For the details of roller bears to be used on the machine, please refer to the diagram 3 and for a list of roller
bears, please refer to the table 2.
4. Electrical system
4.1 Brief description
The machine with foreign advanced singlechip and superior quality electric element is controlled by electric
system, the software system not only realize all kinds movement control, but also has many protective function
with catenation, the capability of this system is very good, and the movement of this system is jarless and
reliable. The move and stop of the main motor function are used by electric circuitry, and it improved the
arrury of machine’s drilling.
