gasoline to clean the antirust on the column. Running the machine without lubrication oil is
strictly forbidden. Lubrication
of the machine as per the stipulation of this documents is
required.
4. Ground wire of the machine shall be well connected. When test running, push jog button in
slow spindle speed to check if direction of spindle revolution is correct.
5. Machine must be stopped if spindle speed or feed rate change is necessary for the spindle
speed is available frequency timing.
6. Please check if cutting tool or work piece is well clamped before machining
7. The red mushroom push button located in front of the spindle box is an emergence push button
for emergency purpose and stopped the machine. Familiar with its position and its use are
necessary.
8. Professional electric service engineer is required for electric maintenance.
9. The machine must be stopped when you need removing away the cutting material around the
drill. Moving the cutting material by hand or by hook is definitely forbidden.
10. Correct use and daily maintenance of the machine are required in order to keep machine
accuracy and its lifetime in long time.
11. We will much appreciate if you could salve some problems of the machine.
In order to facilitate us for the service, please let us know the details regarding the places and

1. Main use and features of the machine:
GHD-35PFV vertical drilling machines are our new products designed and developed
by our-self based on our accumulated experience in so many years in this field. It is a
light, column type, superior quality and high efficiency machine vertical drilling
machine. It is really a multi-function universal machine which could be widely used for
small and middle sizes of work pieces for drilling, spot facing, reaming, tapping etc.
Besides, some machine tool accessories could also be used on this machine. The
machines are suitable for the machining workshop, maintenance workshop and production
line etc.
Features:
1.1 Good in appearance, easy in operation, convenience in maintenance and well consideration in safety
protection
1.2 “Lenze” transducer spindle speed stepless, gear dispatch, configuration compact, convenient timing,
low voice, high transmission efficiency.
1.3 The spindle features good rigidity
and good wear resisting and equipped withtool disassembly and
balancing device.
1.4 The worktable and spindle box could be turned round the column center line or worktable center line
itself or horizontal shaft centerline
by manual and could be moving up and down by manual or
automatically.
1.5 Spindle feed both in mechanical and in electrical with micro feed structure is available in this series
machines.
1.6 Main operation levers and push buttons could be reached easily that makes you comfortable when you
operate the machine.
1.7 Superior quality material with special treatment for the wear-resisting purpose has been used parts such
as gears, worm and worm shaft, rack, lead screw etc as well as for some key parts like spindle and
spindle quill.
1.8A safety protection guard under the spindle box is available as it is not only prevent coolant splash while
cutting but also could observe the machining status.
The guard is interlocked with the spindle, so when the guard is opened, the spindle could not be running
until the protection guard keeps his position.

2.2 For the machine appearance and its main technical data, see diagram 1.
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.
