Knuth Swiss Type CNC Langdrehautomat LineaLunga 25D

Swiss-type automatic lathe with headstock and counter spindle, including turning, drilling and driven tools for efficient complete machining

Machine bed is made of Meehanite HAT 300, carefully heat-treated, high precision machined and subjected to strict quality controls
High-quality bearings and linear guides, produced in Japan, feature both accuracy and excellent wear-resistance
High-performance preloaded ball screws are equipped with precision bearings to ensure sustained, smooth, vibration-free operation
High-torque servo motors by renowned suppliers ensure excellent feed and rapid feed dynamics on all axes
5-axis machining with headstock spindle, counter spindle, and including one C-axis allows for the production of complex parts
Competitive price/performance ratio - a concept for quick adaptation to current market situations
Proven design, low-maintenance, and easy handling
Optimum axis travel distribution results in space-saving design
High-performance coolant system maintains optimum tool temperature for long tool life
Up to 260 mm length can be machined in one step resulting in reduced tooling times; subsequent reclamping of the workpiece eliminates change-overs for machining of the workpiece's back side
For tool mounting, only collet systems that are readily available in stores are used
A 4.4 kW main motor provides sufficient reserve power for demanding production conditions
Rapid feeds up to 24000 mm/min, high productivity and production speeds
Optional rod loader for rods up to 3 m is available; suitable for use with third-party products
