Main use and features of the machine:
JDT
series 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 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,
Milling Plane, slot-milling, angular
mill 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
Double speed motor is to be used for the main drive system with sufficient driving
power but saving energy. Wide spindle speed range is adopted driven by gears.
1.3
Oil lubrication both for the main driving system and for the feed driving system could
be supplied automatically by a new type of trochoid pump when it is working in forward and
reverse
revolution.
1.4
The spindle features good rigidity and good wear resisting and equipped with tool
disassembly and balancing device.
1.5
The worktable 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.
1.6 Main operation levers and push buttons could be reached easily that makes you
comfortable when you operate the machine.
1.7 Spindle feed both in mechanical and in electrical with micro feed structure is available
in this series machines.
1.8 A locking device for the spindle quill is available for the purpose of milling job. There is
a screw hole located at the end of the main spindle for the clamping of different kinds of
milling cutters
1.9 Spindle feed both in mechanical and in electrical with micro feed structure is available in
this series machines.
1.10 Superior quality material with special treatment for the wear-resisting purpose has been
used for transmission parts such as gears, worm and worm shaft, rack, lead screw etc as well
as for some key parts like spindle and spindle quill.
1.11 An adjustable safety protection clutch in the spindle feed device is available in order to
prevent the machine and tools from damage when overloaded.
1.12 A 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.
