The machine tool company Talleres de

Guernica, based in the city of Guernica, where

the Basque Country’s heritage is omnipresent,

has a long experience in metal machining

since its foundation in 1916. Over the years,

Talleres de Guernica constantly modernized

their manufacturing technology and widened

their product range. Their production became

increasingly automated, parts grew, tolerance

values however shrunk.

Mistakes are expensive.

Today, Talleres de Guernica offer mainly chucks

and jaws for many types of machines. Most

parts have a diameter of 2 m maximum – pure

routine for Quality Manager Manu Fuentes and

his team. When a customer asked for a chuck

to be used in a manufacturing centre for wind

turbine components with a diameter of 7 m

and a weight of 65t, new manufacturing and

inspection methods had to be considered.

Manu Fuentes looks back: “We did not have a

lot of experience with such dimensions. But we

knew that manufacturing mistakes would cost

us a lot of time and money. So we decided to

extend our measuring instruments and build

the large part based on highly accurate data.

For us, the maximum acceptable deviation is

0.05 mm.”

Measuring without laser tracker: Impossible.

While evaluating different metrology tools,

the Talleres de Guernica team came to the

conclusion that a laser tracker is the best

solution for the measurement of a large and

immobile object. “Measuring with other tools,

especially with analogue ones, is impossible

for us”, said Manu Fuentes.

The decision was in favour of the Leica

Absolute Tracker AT401. This lightweight

portable CMM can perform measurements

within a volume of up to 320 m. It is battery

operated and certified according to the IP54

protection class, which allows operation

under rough conditions. The system is set up

wirelessly so that one operator with a remote

control is sufficient. PowerLock technology

directs the laser beam automatically towards

the user. Thanks to PowerLock, new users can

be trained quickly.

Delivering a perfect part.

Manu Fuentes: “The portability of the system

was the decisive factor for us. We can put it

on the chuck and are ready to measure within

a couple of moments. The measurement

itself is done very fast.” Between the single

manufacturing steps, the laser tracker is

used to check a list of critical elements on

the chuck. This list includes the position of

the jaws and their features such as holes and

edges or the flatness of the chuck’s surfaces.

“Basically, we measure to exclude any risk

during the manufacturing process”, adds

Michel Clavier, Director of Production. “And

this decision is confirmed every time the

measurement raises a question mark. We will

deliver a perfect part to our customer.”

When a customer of Talleres de

Guernica’s asked for a precision

chuck with 7 m diameter, the Spanish

machine tool company designed a

manufacturing process based on

permanent quality control. With the

Leica Absolute Tracker AT401, new

business opened up.

The laser tracker from Leica Geosystems

influenced Talleres de Guernica‘s presence on

the machine tool market. They are now able to

manufacture chucks in enormous sizes. Manu

Fuentes sums up: “The Hexagon Metrology

solution with Leica Absolute Tracker and PC-DMIS

software are a strong package and exactly what

we needed to solve our business challenge.

Thanks to the tracker, we can access new market

segments.”
