OPTIMAX 740: lathe range designed for machining medium-sized parts (up to 4 meters). Available in 2 or 3 axes, this learning lathe provides the operator with all the comfort for simplified, superior quality machining of individual parts or prototypes, including long parts. The precision and robustness of the tooling lathe are ensured by its wide hardened and ground bed, as well as its optimized guidance.

Made in France

Our OPTIMAX 740 learning lathe, heir to the HB 725, is designed and assembled in our workshop in France by our machine tool experts.

Technology & Operator

Our software was invented by turners, for turners, with the key words: simplicity, ergonomics and productivity.

Support & training

Because CAZENEUVE is close to its customers, we are committed to meeting your needs before, during and after the use of your machine, by offering certified training.

Built-in security

Very involved in user safety, CAZENEUVE requires a reinforced safety protocol for its machines, right from their design. Conformity with standard 2006-42 CE.

Our OPTIMAX 740 learning lathe (or tooling lathe), the descendant of the legendary HB 725 conventional lathe, has retained the robustness of its predecessor while evolving in all areas. In particular, precision and ease of use have been improved with the aim of machining single parts and/or prototypes even more easily.

What better way to see this than with a video demonstration? Come to our workshop to see the full potential of the OPTIMAX 740 parallel lathe, even more powerful than the conventional HB 725!
