Heavy duty 4-guideway lathe designed for highly efficient machining of long and heavy workpieces

HACO has increased its range of CNC turning centres with the addition of the TUR 4 MN series of heavy duty lathes, developed for rough and finish turning of heavy steel and cast iron workpieces.
  • Turning diameter: up to 3 000 mm
  • Distance between centres: up to 22 m
  • 4 independent guide ways
  • Component weight: up to 100 T
  • Turning torque: up to 300 000 Nm

The whole machine concept and design is based around an extremely rigid cast iron step-bed, with 4 hardened guide ways to assure maximum stability.

Total consistency

The integration of innovative mechanical features, advanced programming techniques and a powerful control system results in a quality CNC lathe capable of high precision rough and finish machining, contouring, precise taper turning, threading and facing, with the constant cutting speed feature ensuring total consistency.

Developed in co-operation

Different options, both standard and bespoke if required, enlarge the machines' capabilities on turning, milling, drilling or grinding. TUR 4 MN machines can be configured and, if necessary, developed in close co-operation with the client in order to meet the individual users' needs and dependent on the application.

We are proud to announce that we have already been successful in securing several TUR 4 MN projects and orders from Thyssen Krupp in Germany and Ellwood City Forge in the USA.

Outokumpu VDM puts first lathes into service

Outokumpu VDM’s bar production is currently being re-organized. The re-organization goes hand in hand with investments in modern machinery and equipment. Part of the respective investment program are four TUR 4MN (1100 x 7000) lathes from FAT/HACO.

Until now, Outokumpu VDM’s finishing line for bars is located in Altena, Germany. Here, the producer of nickel, titanium and zirconium alloys and special stainless steels processes hot-rolled and forged bars and semi-finished products in its heat treatment furnaces, lathes, and peeling and grinding machines.

“In future, forged bars thicker than 125 mm will be processed on our brand new factory floor in Unna, Germany, next door to our melting and casting shop and our open die forge which went into operation in 2008”, explains Peter Duempelmann, Project Manager at Outokumpu VDM. Forged bars with a thickness under 125 mm and hot-rolled bars will further on be processed in Altena.

Besides the new turning lathes, other modern production equipment – such as new cutting machines and new ultrasound testing facilities – is currently being installed at both sites as well. During the upcoming months, all new machines will step by step be integrated into the production process.

“The first two lathes have already been put into service. Thanks to the excellent co-operation of all parties involved, we were able to meet our ambitious timetable. All technical questions that came up during the project could be clarified promptly by our competent counterparts at FAT/HACO. From the very beginning, the team at FAT/HACO had a clear focus on our needs and did an excellent job”, says Duempelmann
