Case Study REDEX Ferrières When high-precision mechanical quality rhymes with Hexagon Metrology CMM

Specialising in high-precision mechanical

engineering, Redex was founded in 1949

and is still driven by the same goal: the

quality of its products in a context of

long-term development. Managed by the

grandson of its founder, Redex focuses

on two main product lines: a machine

activity for the strip and wire industry and

a power transmission activity. Every day,

more than 330 employees ensure that the

group continues to optimise its techno-

logy, a fact which is reflected in a number

of patent applications being filed every

year. More than one third of the compa-

ny’s turnover is generated by products

developed over the past five years while

70% of its turnover comes from products

sold outside Europe.

«Redex counts on the development of

its production processes to ensure a

constant increase in production quality,»

explains the industrial director Pascal

Vieugué, adding «We invest several

million euros per year in new production

means. Our development in the machi-

ne-tool market is an important stage in

the Redex quality system, as mechanical

installations with no play require very

limited tolerances and thus a very precise

dimensional inspection».

Already a pioneer in its field and abso-

lutely meticulous about the quality of

its products twenty years ago, Redex

purchased a digitally-controlled DEA IOTA

inspection machine which measures 1

point/second with a precision of approxi-

mately 5µ + 4/1000 as well as a manual

OMICRON machine. «Our 1984 DEA OMI-

CRON is still in excellent working order»

boasts Mr Vieugué. «Retrofitted» with

PC-DMIS Pro, simple and easy to use, the

DEA CMM certainly has a number of years

left in it yet and will be an integral part

of the new Redex production site which

is still under construction. Nevertheless,

the products developed by Redex require

an altogether different level of precision.

The Leitz Reference machine recently

purchased by the Ferrières company has

taken metrology to a new plane. «At a

rate of 750 points per second and with a

level of precision of less than 5µ, the Leitz

Reference has taken inspection to a new

dimension. The automatic inspection of

large parts or large units is both quick and

practical and offers unrivalled quality,»

explains the industrial director.

«By once again placing our trust in

Hexagon Metrology, Redex has reaffirmed

its decision to call on a company which is

capable of offering a real solution to a spe-

cific problem. Its top-quality commercial

service and specific help in developing

the inspection process were crucial to

our choice,» explains Pascal Vieugué. The

QUINDOS software, already a firm favou-

rite with the Redex metrology laboratory

staff as a «complete tool», ensured that

the automation of the inspection process

became a reality. Mr Vieugué adds that

«the simple, automatic, direct and com-

Specialising in the design, production and

distribution of high-tech power transmission

systems, REDEX is led by a team of top-

flight engineers and makes every effort to

optimise the technologies used, both in

designing and manufacturing the products.

REDEX ANDANTEX is a genuinely

international company with employees

hailing from around the world and who

are all united by the same passion for

their specific field: ultra high-precision

mechanical engineering.

prehensible report is a genuine measuring

tool».

The rapid expansion of the company and

the increasing demands in terms of three-

dimensional measurements encouraged

the group to acquire a third CMM. «The

DEA GLOBAL Performance 5.5.5. offers

Redex flexibility in terms of ‘self-service’

measurement resources. PC-DMIS Pro

facilitates automatic use which goes far

beyond the possibilities of simple manual

machines. Its digital, user-friendly controls

and small size support the choice of the

company to invest in qualitative resour-

ces which are perfectly adapted to our

needs. Hexagon Metrology is not simply a

supplier of measuring tools; it has become

a genuine partner. The challenges facing

Redex in the future, including continued

investment with regard to organisation,

the development of production stan-

dards using automated machines and an

increase in production, will require an

exceptional quality label and exceptional

CMMs» concludes Mr Vieugué.
