Leonard Big

The biggest moving column vertical machining center on the market. Perfect for 3 to 5 continuous axes machining of big-sized pieces. Strong structure and great power combined with the highest accuracy.

CERTIFICATION

LEONARD BIG is the largest model (1200 mm transversal and vertical travels) of the family of Rema Control’s vertical machining centres with moving gantry.

The base is monoblock and well-sized, electrowelded and stabilised following the latest thermal treatment technologies which ensure high stability, rigidity and sturdiness. On the bed rests the saddle (that develops the X-axis movement) upon which is located the column (that develops the Y-axis movement). The vertical travel is performed by the head group. The column, the saddle and the head group have a newly designed thermo-symmetrical structure, carefully designed with the support of the FEM-Design modelling software, which guarantees high resistance to bending. All machine moving parts always rest on guides, even at the end of their travel. The guides are provided with preloaded re-circulating roller pads that thanks to the low friction coefficient, ensure excellent positioning precision and speed.

Highly reliable machine thanks to its top quality components and to a smart design that minimises maintenance requirements.

LEONARD BIG is available in various configurations, from 3 to 5 simultaneous axes, and various lengths (up to 8,000 mm of X travel). It can be customised with components and options that make it suitable for any type of material and application.

Besides its high rigidity and precision, LEONARD BIG features great machining flexibility and ease of tooling and piece clamping.

STRENGTH AND STABILITY

New generation thermo-symmetrical gantry designed with the support of the FEM-Design modelling software, for rigidity and stability at the top of its category.

Recirculating ball screws and large roller guides.

Monoblock base, electrowelded and normalised with special reinforcement ribs.

PERFORMANCE AND PRECISION

Extensive work capacity for the machining of even large and heavy parts.

Large volumes of material can be removed thanks to he extremely rigid structure and the high torque of the spindle.

Slide and gantry are always supported by the guideways, preventing a rocking action often caused by lack of support.
