MYL   S.A.

Mendaro – Guipuzkoa

Spain

In 1969 Manuel Gil Cengoitia, driven by an unstoppable spirit of enterprise, founded Talleres MYL and embarked on his career on just 200 m2 of premises in Elgoibar, designing, making and repairing spindles for machine tools. He set up a flexible family business committed to closeness to its customers and an end product of excellent quality. MYL today is founded on this same attitude, in the conviction that this is the best and only way to meet the needs of those who depend on our work. Today, run by the second generation of the family on our 1,500 m2 of premises in Mendaro, and with a much more structured organization, we are committed to innovation, knowledge management and B2B partnership in order to meet the needs of a much more competitive, global market. This philosophy is strengthened by the creation of work groups who combine experience with a strong orientation towards innovation to promote new, better technological progress that enables us to take on the demanding projects of the future.

We are convinced that commitment to our customers, teamwork and an ongoing commitment to technology are the key to confronting the new challenges of a highly demanding global market.

EXPERIENCE: The experience accumulated over more than 45 years of existence has enabled us to build up an inestimable database and valuable knowledge of the product and market. If we do not have the design the customer is looking for, we know or will find the place to start.
QUALITY: Quality must be seen, touched and felt, therefore each one of the manufacturing and repair process stages is very carefully controlled and available on an extranet that we share with our customers.
NEAR-AT-HAND: To be able to speak to, interact with and directly contact our customers is, for us, a luxury and a necessity. As only in this way will we get to know their real needs, treating every model with the devotion and level of detailed care that it deserves.
DESIGN & RETROFITTING: Thanks to the use of our own technologies and engineering, we are capable of manufacturing and retrofitting special spindles adapted to customer needs.
TRACEABILITY: From the arrival of the spindle at the factory, to its identification, dismantling, cleaning, testing and assembly and final repair. Each and every one of the steps is strictly controlled, identified and monitored by our team of professionals.
3D DESIGN: Each and every one of the designs on which we work is prepared in 3D by a specialized team and expert.
CUSTOMISATION: We customize and adapt any design that our customers require. Our technological capability and flexibility allows us to design a new spindle or retrofit following the technical specifications of the customer.
FLEXIBILITY: To be able to respond to the needs of our customers, whoever they are, and taking painstaking care of each one of the stages is our greatest satisfaction.

OUR PRODUCTS: We manufacture and adapt any spindle on the market
