C - contact roller
The contact roller can be either rubber covered or steel . Further the hardness of the rubber can be varied from 40 to 90 depending
on the application.
A soft rubber covered roller has more adaptability to the unevenness of the surface and is therefore preferred for veneer – lacquer
sanding operations, while a hard rubber which has less or no adaptability is good for calibration
For calibration a smaller dia roller is more effective, the angle of contact is more open, the surface of contact is lesser which means
less friction and more material take away.
T1 – Pneumatic Pad
Ideal for fine sanding of solid wood panels and also for simple veneer sanding.
The pneumatic pad is an alternate to sectioned pads where the customer is cost conscious.
The fine sanding can be achieved by adjusting the rise and fall of the air cushion pad. By inflating the pad lowers and deflating
the pad retracts.
T – Electronic Sectioned Pads
The electronic sectioned pad unit is the ideal unit for fine sanding, they give an ideal protection of the edges and corners of panels and
at the same time a finer & flatter finish of the surface.
The pitch of the sections commonly used is 32mm while it is also possible to have 16 mm but will be more expensive.
Can handles thickness variations up to 2 mm while removing even material from panel to panel
U – Combination head
In a combination unit you have a pad as well as a 200 dia cylinder. The pad unit can be either pneumatic (standard) or of electronic
section pads (optional).
It is possible to use the machine with either of the two heads or both the heads at the same time.
Ideal for small volume production where it is required to do calibration as well as fine sanding.
W – Planer head
The planer head has a dia of 180 mm with 8 rows of tips, set helically and with inclined cutting edge which gives a smooth impact.
( 504 nos x 14 x 14 x 2 mm carbide tips)
Advantages of using cutter head :
Possible to remove more material 0.5 to 2 mm and if required can go up to 5 mm ( not possible with sanding belt)
Low motor power usage – 22 kW / 30 kW
Low cost of tools. One set of tips lasts 20 times than that of sanding belts
Possible to achieve +_ 0.1 mm tolerance in thickness
Higher level of surface finish. The 1st sanding unit after the planer starts with 100/120 grit and 2nd can have 150 grit.
TSF – Super finish unit
In the super finish unit there is an intermediate chevron belt (with independent tensioning) which runs at a different speed than the
belt and the working pressure of the pad sections is transferred through this intermediate belt.
We get a higher surface finish because the contact of the felt lamellas on the sanding belt prevents the oscillation marks caused by
the sanding belt.
The super finishing process assures a very homogeneous surface finish even with very fine grit belts . Typically we use belts above 320
The air flow between the felt stripes of the lamellar belt cools the sanding belt so the life of the sanding belt is higher and sanding
efficiency is higher.
X – External cross belt unit
The cross belt unit is standard equipped with electronic controlled sectioned pads TPR 32 with 42 sections each 32 mm wide.
Is used to smooth the grain of the wood – veneer and also of the lacquer surface to ease the longitudinal sanding operation.
The lamellar chevron belt running in between the sanding belt at a different speed gives high surface finish especially suitable for
G – Structuring Brushes
The brushes comes with steel wire bristles.
The structuring brushes are used to give an antique or raised grain affect on the wood panels. Depending on the depth of structuring
required the motor has to be appropriately selected.
Each brush unit is equipped with an independent thickness positioning system to compensate for wear as well as exclusion in
