PLANO MILLING CONVERSION KIT
Is Plano milling conversion required?
•
Attractive price of Plano milling head, table drive mechanism have come
down because of mass production, confirmed design, latest
manufacturing technologies.
•
We have supplied Plano milling conversion kit almost every comer of
India with different types of planners, from last five years.
•
Plano Milling head design confirmed to satisfaction of customers
•
Efficiency of old machines increased drastically.
•
Since the change of table speed from high to very low, reduce
maintenance and brake down, wear and tear problem and entire cutting
load is taken up by Plano milling head.
•
Small investing will increase machine efficiency by 10 to 12 times,
without additional manpower and space.
How a planer converted to Plano milling.
A) Mounting Plano milling head in the existing tool post of planner.
B) By providing an auxiliary table feed unit in the existing drive system of
the planner. If the planner does not have slow table speeds, suitable for
Plano milling mode.
Selection of a milling head.
Milling head are available. In 5HP, 10HP, and 20HP capacity depending
upon the size of the planning machine, suitable for maximum Dia
160mm, Dia 310mm and Dia 450mm cutters respectively. Most of the
machines on 16feet stroke suitable for 5HP milling head , imported and
Indian planer machines like Cooper, HES, Hercules, Champions etc are
suitable for 10HP and 20HP capacity. It also depends upon the size of the
cutter you use for milling and also depends upon the type of material
your cutting in Plano milling Machine
Please re-vert back if any clarifications regarding milling head.
Intermediate Back Plate.
An intermediate Back plate is fixed between the milling and tool post
carriage, taking location of the valuable and circular “T” slot of the
carriage Graduated collar will guide to positioning of the spindle access
+/- 45degree. The back plate guide easy tilting mechanism of the milling
head and also leads the full utilization of the available quill movement of
the milling head. It is difficult to support the unbalanced weight of the
desired angle. Hence a mechanical tilting mechanism consists of a worm
and a sector gear is provided to the back plate.
Side Milling Attachment
Side milling attachment virtually adds side milling capabilities to the
vertical milling head. Side milling attachment mounted on milling head.
With the help of flange having “T” slot & graduation collar +/-360degree,
enable side milling attachment to swivel +/-360degree. It receives drive
to tenon and an adaptor, the Side milling attachment consists of a pair
of spiral bevel gears, case hardened and lapped.
Table Feed and Cross Feed Control System
There are 2 types of Table drive control system are available
1. Mechanical Table control system.
Consists of 3HP Electrical motor and two numbers of Nisson
Automobile gear boxes.
It provides 25 stepped table speeds in planomilling mode ranged from
30mm per minute to 600mm per minutes.
The output of the table drive unit is connected to the main drive shaft of
the planning through a chain and sprocket mechanism. The table drive
unit will be supplied complete with Motor. Bracketories, chain guard,
speed chart etc.
2. Electrical table feed and cross feed control system.
Consists of a worm reduction gear box, motor and frequency
converter, control panel and pendent. The table to move from 30mm
per minute to 400mm per minute in step less range in planomilling
mode. The unit is complete with all require cables. Output fittings,
chain and sprocket etc.
Required controls for For/Rev/Stop Rapid/Stop selectors for table
feed and similar start/stop and for/rev selector for spindle motor will
be provided. The Spindle RPM and table feed rate will be adjustable
easily using the potentiometer provided on the pendent of the
machine. Also calibrated voltmeters giving the spindle and table
feed rate will be provided on the pendent. Controls for selection of
planner Plano- milling mode will also be provided.
All necessary interlocks and required sensors / limit switches etc will
provide. This include interlocks by operation of planner motor only
when clutch of Plano-milling is positively disengaged, Table stroke
limits, Spindle rotation-table feed interlocks etc.
Complete required cabling material like cables, hoses, connector’s
etc. for cabling from panel to pendent, motors, limit switches, clutch
etc., need to be provided
i) AC Motor and Gear box assembly.
This will have an AC induction motor of reputed make fitted with an
external axial fan for forced conversion. This helps in proper heat
dissipation, during motor running continuously at all RPMs. The
Motor will drive the input shaft of a reduction gear box. For this a slip
frees suitable timer belt drive. Reduction gear box will be of reputed
make like Elecon /Radicon/Cyclo etc.
ii) Controls.
Complete control system for the planomilling operations will
need table provided. The controls will include controls for
spindle and table feed and necessary inter locks.
All the required controls will be housed in a separate electrical
cabinet placed on floor near to the place where reduction
drive unit is fixed. All the elements used like MCBs,
contactors, cables etc. for the control system will be of
standard reputed makes easily available in India like
Siemens/L&T/Technic/Indo kopp etc
