Knee Type Milling Machines
Standard Models : HF1, VF1, UF1, HF2, VF2, UF2, HF3.5, VF3.5, UF3.5
Rugged, powerful and precision knee type milling mahines are offered in Horizontal, Vertical
and Universal versions in size 1, size 2 and size 3.5 models to suit the varied requirements of
the customer. Electrical cycle controlled models in horizontal and vertical versions are offered
for series and mass production of components.
Features
Rigid Structure
The rigid spindle housing, cross ribbed box type column structure, closed box
type knee design ensure optimum chip removal capacity and surface finish. The
rigid structure ensures vibration free and smooth machining.
Work spindle
Optimum spacing of precision taper roller bearings ensure vibration free cutting.
The bearing preload is adjusted by a common nut.
Vertical milling head can
be swivelled either side of
vertical by 45deg.
Vertical Milling Machine VF1
Power operated feedin longitudinal & cross
directions for standard Size 1 machine. Rapid
feed in longitudinal direction as option.
Guides
Table, cross slide and the knee slide in dovetail guide ways.
The dovetail guide ways are amply dimensioned to resist
extreme machining loads. The guide ways are protected
constantly from the ingress of swarf and coolant.
Three lever control for spindle
speed selection
Three lever control for

Milling head can be moved
away from work position
quickly with ease and
parked on the side of the
column
Table drive
Lead screw with 2 nuts for backlash free setting. Feed
selection by sliding gear drive. Reversal of movement
direction by motor reversal, dead accurate stop by brake
clutch. Change over and rapid traverse feed by multi disc
clutch.

Power operated feed and rapid
traverse in longitudinal, cross and
vertical directions for Size 2 & 3.5
models.
Differential thread
clamping system for knee
ensures higher clamping
force.
Large tray on the base
plate to collect chip and
coolant
Universal Milling Machine UF2
„
Motorised Over Arm (MOA)
An added advantage of vertical spindle on horizontal and universal
machines on size 2 and size 3.5 models.
MOA is supplied with a vertical milling head. A manual quill stroke
of 70 mm is available on milling head. MOA comes with
independent drive motor of 3kW (4HP) power. Spindle is provided
with 12 speeds in the range 45 - 2000 rpm and ISO 40 taper.
Since MOA itself is used as over arm for mounting arbor support
bracket, the machine doesn’t require normal over arm.
Horizontal Milling Machine HF 3.5
Rigid over-arm makes overarm
brace superfluous
Lubrication
Central lubrication for guide ways and
leadscrews. Splash lubrication for speed and feed
gearing.
Coolant
An electric pump mounted at the rear of the
machine base ensures copious flow of coolant
to the work zone. The coolant is discharged in to
the built - in coolant tank in the machine base.

coolant diversion with

HF3.5E, VF3.5E
These special version machines are provided
with highly reliable Programmable Logic
Controller (PLC) which enables programming of
table movement in longitudinal direction.
Extremely useful for series and mass production
of components with consistent accuracy, these
machines ensure minimum idle time and
optimum efficiency.
Attachments and Accessories for Increased Flexibility
VMH can be swiveled 45 deg. on either side
and clamped. The quill carrying the cutter
spindle can be moved manually along its axis
up or down and clamped in the desired
position. Four position turret stop and rapid
quill movement facility (for size 1 & size 2
machines only) are provided as optional
features on vertical milling head.
UDH allows simple, differential and
compound dividing. With universal milling
machine it can also be used for spiral
milling. Spindle axis can be tilted in the
vertical plane.
RMA permits manufacturing of racks with all
modules normally required. Suitable for
horizontal and universal versions, it consists of
a milling unit, a fixture and a manually operated
dividing attachment connected to the table drive
lead screw.
This equipment can be used for
milling and drilling operations
whenever direct indexing up to
12 or 24 divisions is required.
Machine vices are offered with a solid base and
also a swivel base. They are supplied with jaw
width 100 – 250mm and clamping capacity up
to 150mm.
Ideal for circular dividing, these are used for
accurate rotary movements. They are offered
in 250mm dia. and 400mm dia. Motorized
version is supplied for 400 mm table.
Used for milling of accurate radial grooves &
slots and drilling radial holes in round
components. It can be used for vertical or
horizontal positions.
Consists of a fixed base over which a swivel base
and slotting ram are mounted. The drive from the
machine spindle is transmitted as a reciprocating
motion to the ram for machining of slots.
