MASTERBRUSH:
DMC INTRODUCES A TOP-CLASS BRUSHING MACHINE FOR CABINET DOORS |
|
|
|
For over
thirty years DMC has been working alongside the world’s leading
manufacturers of cabinet doors. This long and close collaboration has
enabled DMC to develop numerous innovations in the calibrating and
sanding of cabinet doors. Many of these technical innovations have been
incorporated in machines which have become the benchmark for the entire
woodworking machinery sector. The Finesand superfinishing orbital pad
was introduced by the company in 1995 and is still considered by many to
be the best solution for the superfinishing of cabinet doors. The new
Masterbrush automatic brushing machine continues in the great DMC
tradition and incorporates the company’s experience and expertise in
industrial brushing machinery. |

The
advantages of DMC quality
:-

Masterbrush offers
numerous advantages in comparison with hand brushing. First and
foremost, there is a very considerable increase in
production throughout because cabinet doors can now be sanded
continuously. Secondly, automatic brushing guarantees a high
level of uniformity in the finish of all the doors being
processed. This is a particularly important factor where the doors
are to be painted. Masterbrush is the ideal choice for the
finishing of assembled cabinet doors, frames and profiled parts such
as frame strips, frames, cableways, beading and skirting boards.
The unit can of course be used as a stand-alone machine but is best
employed on automatic production lines where it can make a
significant contribution to increasing production rates and finished
product quality. |

At Xylexpo 2006, the new
Masterbrush unit is presented in line with a Unisand K M5 calibrating
sanding machine fitted with Finesand orbital pad units. This is an
unbeatable integrated solution. A world beater for technology and
productivity that offers a finish quality to surprise even the most
demanding customer. |

When we used to sand
by hand … |

Many of
the reasons why DMC decided to introduce a next-generation automatic
brushing machine are linked to the increasingly more widespread use
of water-based paints. Wood fibres absorb water and tend to
lift and stiffen as a consequence. This tends to make surfaces
coated with water-based paint rough and irregular. To minimise these
surface defects, the unfinished substrate has to be finely sanded;
fine sanding is also necessary before the application of the final
coat.These
operations are not possible on a traditional contact sander which is
|
|
|
only suitable for sanding flat
surfaces.The
traditional sander cannot sand the raised outer frame of a
cabinet door where the difference between the outer frame and
the inner panel is often considerable. Brushing is the only
effective solution for cutting raised wood fibres and providing
a uniform finish on ready-assembled cabinet doors. |
|
The new DMC brusher also
performs another important function necessary in the painting
process of cabinet doors – rounding or the sanding of the
sharp panel edges. The Masterbrush rounding unit consists of
multiple rotating discs fitted with radial abrasive strips
mounted on stiff bristles. The disc movement is orbital rather
than being fixed or crossways to the workpiece feed path. This
orbital movement is one of the principal new features of the
unit and is in the process of being patented. The orbital
movement of the unit means that the single discs round the
sharp edges more efficiently and can even reach the most
inaccessible areas such as the inside corners of the door frame.
DMC design engineers took their initial inspiration for the
Finesand orbital pad unit from watching manual sanding
operations. Manual sanding is widely considered the best method
and once again the design engineers took their lead from here.
The Masterbrush rounding unit reproduces the same movement on
the cabinet door as a manual brusher operated by a skilled
operator. |
