Introduction
The ROBOFORM 23P/53P, the fruit of
CHARMILLES’ world experience in
EDM, is not only amazingly flexible,
making it possible to cover
numerous applications, but also
offers exceptional reliability and
ease of use.
Thanks to it’s rugged mechanical
structure it can perform highly
demanding jobs with an unrivalled
quality/price ratio.
Equipped with an efficient and well
proven generator, the ROBOFORM
23P/53P are the ideal partner for
carrying out demanding applications.
The Machines
_Repeatability of machining ensuring the production of high quality of the parts produced.
_Multi-task CNC for increased
productivity.
_Expert Systems for optimum
perfomance.

The Machines
Rigid and compact
The use of cast iron and the short
C frame design ensure static and
dynamic rigidity of the mechanical
structure. The cross-table, fitted with
linear glass scales, guarantees the
positioning accuracy. The ergonomics
of the machine have been designed
to provide the most favorable ratio
between the floor space area and the
work surface area.

C axis
A rugged C axis delivers high positioning precision (0.001°) regardless of
electrode weight (up to 100 lbs) and
full machine current. Completely
intergrated, the C axis is easily extended to increase X and Y travels when
machining very large parts.

Positioning measurements are done
by means of linear glass scales fixed
directly onto the X, Y and Z axes of the
ROBOFORM 23P/53P, thus eliminating errors that may arise when the
screw thread becomes worn or too hot.
Furthermore, before delivery, every
ROBOFORM 23P/53P are rigorously
checked by means of a laser in order to
guarantee the best possible accuracy.
Linear Tool Changer LTC
Designed to be economical but
efficient, the fully integrated Linear
Tool Changer is ideal for less complex
applications requiring few electrodes
or involving longer cuts.

Generator
A «success story»
More than 2 500 generators of this
type are in operation worldwide,
proof that its success is no coincidence. With this generator the
ROBOFORM 23P/53P can provide
outstanding performances for
a wide variety of applications. It
guarantees repetitiveness, surface
homogeneity and precision.
In cases where there is a particular
need for power in roughing, the generator can supply up to 128 Amperes
(optional) so as to attain high rates of
material removal. While fast machining is ensured, the geometric details
of the electrodes are preserved.

In addition the ROBOFORM 23P/53P
are equipped with functions for automatically measuring the tool offsets
along all four axes X, Y, Z, and C.
Hence the exact position of the cavity
being machined is guaranteed whatever the offsets of the electrode.

Sparking
Whatever the challenge,
CHARMILLES delivers the right
spark solution available through
menu-driven programming.
As illustrated on these pages, each
machine supports a variety of specific
mouldmaking applications regardless
of complexity or difficulty.
Solution for injection point
Each mould has at least one injection
point. This type of machining requires
a 3D cycle and a strategy adapted to
evolving electrode surfaces.
The calculated geometric data
necessary to describe the electrode
movement is automatic, based on
workshop drawings.

Surface homogeneity
A uniform texture of the injected part
is directly linked to the quality of
surface finish.
To respond to the need for a perfect
surface finish of the mould,
CHARMILLES has developed a
“Surface ” technology designed to
meet the most stringent criteria of
surface homogeneity.

Micromachining
Especially when electrode dimensions are reduced, surface finish
and wear become decisive factors in
terms of performance.
To address the needs of the connectics and micromachining sectors in
particular, CHARMILLES has developed a dedicated module designed to
reduce electrode wear by up to 30%
and to offer unequalled
surface finish.
