Description
CNC Lathe with Siemens 808D Advanced Control
The Bernardo CK 400 x 1000 CNC lathe is a professional machine designed for high-precision machining of medium and large workpieces. With a distance between centers of 1000 mm and a swing over bed of 400 mm, it offers great operational capacity. The spindle with a 66 mm through-hole and A2-6 mount, combined with the electronic gearbox with variable speed of 30–2500 rpm, ensures flexibility and high performance. Equipped with an 8-position automatic tool turret, Siemens 808D Advanced CNC, automatic lubrication, and a 200 mm hydraulic self-centering chuck, it ensures productivity and ease of use. Thanks to its robust structure (1960 kg) and positioning accuracy of ±0.01 mm, it is the suitable choice for workshops, mechanical companies, and production departments that require reliability, speed, and machining quality.

Frequently Asked Questions
What is the Siemens 808D Advanced control and what does it allow?
The Siemens 808D Advanced is the numerical control (CNC) mounted on Bernardo CK lathes. It allows for the programming of automatic machining cycles in ISO/DIN code (G-code), on-screen simulation of the tool path before execution, management of up to 16 tools in memory, fixed cycles for turning, threading, and drilling. The ergonomic keyboard and color screen make it accessible even to operators new to CNC.
What is the difference between CK 320, CK 360 and CK 400?
The number indicates the center height (swing radius): CK 320 → max Ø 320 mm (center height 160 mm), CK 360 → max Ø 360 mm (center height 180 mm), CK 400 → max Ø 400 mm (center height 200 mm). The distance between centers (500, 750, 1000 mm) indicates the maximum workpiece length. Choose the model based on the maximum diameter and length of the workpieces to be machined.
Can an operator with experience only on manual lathes use the CK?
Yes, with a learning curve of 2–4 weeks. The Siemens 808D Advanced is designed for the transition from manual lathes to CNC: it has an "MDI" (Manual Data Input) mode that allows single operations to be performed as on a manual lathe, and conversational programming guides the operator in creating the program without having to know G-code from scratch.
Are spare parts and assistance available?
Original spare parts available with 3–5 business days shipping. Customer support in Italian available.
How much space is needed in the workshop?
CK lathes are fixed workshop machines. Consider space for workpiece handling in front of and behind the machine equal to the distance between centers, plus 80 cm on each side. For machines over 500 kg, coordinate with Krollit for unloading equipment.
