Zehatz
When the «µm» is split
by ED wire cutting
Ultra precision
knows no frontiers
Zehatz, based in the Basque region
to the east of Bilbao, was
founded in 1992, has 40 employees
on its payroll today and is
the manufacturer of a wide variety
of products, such as high
precision workpieces, spare
parts, tools and components.
The north Spanish undertaking
supplies them to the aerospace,
automotive, food canning, microelectronics
and medicine industries
worldwide. Zehatz' company
philosophy builds entirely on
mutual trust and cooperation
with customers. This includes
the joint development of critical
components, such as production
and checking tools, specimen
parts and templates – always
under the viewpoint of offering
the customer solutions that are
competitive and improve products.
This is implemented with
an innovative design department,
an ultra modern range of machine
tools and also, as the heart
of the company, a measuring
centre for the highest standards.
Ultra precision thus becomes
visible, measurable, demonstrable
and comprehensible for customers.
An important argument,
with which Zehatz has positioned
itself right at the top in global
competition. Recently, Zehatz
has also integrated an Agiecut
Vertex 2F into its ultra precision
concept. The ED wire-cutting
machine proves that it meets the
demand with its precision results:
surface roughness Ra 0.05 µm,
fitting accuracy ± 1 µm and inside
radii of 0.03 mm with finest
wire and automatic threading are
standard features.
Quadruple copper electrode with which
mould inserts for a blanking tool are ED
machined. The outside and inside contours
are ED wire cut to an exact fit. During
blanking, the tool inserts give the
form for the pull openers for food cans.
The three-dimensional representation
generated with a CAD program shows a
current Zehatz project. Before the production
stage, the new type of tool is tested
virtually and optimised in accordance
with production engineering requirements.
The Agiecut Progress V3 ED wire-cutting
machine is set up by means of the
«Agiejogger» handbox. The operator can
carry out all the important control functions
with it.
