CK 320 x 1000 CNC Lathe with Siemens 808D Advanced
The Bernardo CK 320 x 1000 CNC lathe is designed for precision machining of large workpieces, while maintaining compactness and stability. With a distance between centers of 1000 mm and a center height of 160 mm, it allows machining of parts up to Ø 320 mm. The spindle with a 56 mm through-hole and A2-5 mount ensures robustness and versatility. The 6-station automatic turret enables fast and productive tool changes, while the Siemens 808D Advanced CNC control offers easy management and programming. The continuous speed adjustment from 150 to 2500 rpm makes this lathe suitable for various materials. Equipped with integrated cooling, automatic lubrication, and an electronic handwheel, it guarantees efficiency and long life. With a weight of 1190 kg, it is the choice for workshops that demand reliability and constant precision.

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 CK Bernardo lathes. It allows programming automatic machining cycles in ISO/DIN code (G-code), on-screen tool path simulation 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 (turning 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 CKs?
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 as on a manual lathe, and conversational programming guides the operator in creating the program without needing to know G-code from scratch.
Are spare parts and assistance available?
Original spare parts available with 3–5 working day shipping. Customer support in Italian available.
How much space is needed in the workshop?
CK lathes are stationary workshop machines. Consider space for workpiece movement in front of and behind the machine equal to the length between centers, plus 80 cm on each side. For machines over 500 kg, coordinate with Krollit for unloading equipment.
