Spindle
The spindle uses high-strength, double-row precision steel bearings. It is filled with a lifetime lubricant that eliminates the need for daily maintenance.
Motor
The CNC turning center uses a powerful brushless AC motor that drives the spindle and increases cutting speed.
Ball Screw
The ball screw uses a rolling motion instead of a sliding motion. It undergoes nut preloading and screw pre-tensioning to eliminate backlash, reduce friction, and improve positioning accuracy.
Slide Block
The slide block incorporates a recirculating ball nut that is up to 98% efficient, ensuring low-friction power transmission between the slide block and screw.
Control System
Our CNC turning centre is compatible with popular control systems such as Siemens and GSK. It supports both conversational and CNC programming.
Base
The base is made of high-quality castings and reinforced with ribs. These ribs have been optimised using finite element analysis to improve the base’s rigidity, thermal stability and vibration-damping capabilities.
Guideways
The CNC turning center uses high-rigidity square guideways with sliding surfaces that are treated with specialized scraping processes and precision oil grooves. This design delivers outstanding transmission efficiency.
Chuck
Our chuck is equipped with a powerful hydraulic system and hydraulic sensors that provide significant clamping force. This reduces vibration amplitude during part rotation and improves machining accuracy.
Coolant Tank
The CNC turning center has two independent coolant tanks that prevent debris from entering the machine. Additionally, they can be removed separately for easy cleaning and maintenance.
Chip Removal System
The chuck’s tilted design, combined with high-pressure coolant from above, effectively removes debris from the chuck and the telescopic guide rail cover.
Tool Turret
The rotating tool turret allows for quick tool changes during machining. Tool change time can be controlled in two seconds, improving machining efficiency.
Tailstock
The tailstock is made of high-rigidity cast iron, which offers excellent vibration resistance. Its precise symmetry with the spindle housing guarantees high positioning accuracy.
What is the difference between CNC turning centers and CNC lathes?
A CNC lathe is a basic type of computer numerical control (CNC) machine. It clamps the workpiece in place using a fixture and rotates it around a rotational axis. The spindle controls the tool, which performs radial and axial cutting on the workpiece. Multiple clamping operations are required to machine multiple surfaces. The lathe’s functionality is relatively limited as it is primarily used for machining shaft-type, ring-shaped, and cylindrical parts. Therefore, it is relatively inexpensive.
The CNC turning centre can perform a few more operations than the basic CNC lathe. The general-purpose model includes full turning functionality and can also mill, drill and tap. This makes the power unit a highly versatile engine that changes tools automatically. In other words, the part isn’t too restricted. This system can also machine intricate parts on the same machine. A CNC turning centre will only cost more than a basic CNC lathe. Over time, however, it is more efficient and accurate, which can help you achieve a greater ROI.
What is the difference between a CNC turning center and a CNC milling center?
In turning centres, the workpiece rotates, allowing machining to take place while it is held in a stationary or moving spindle. In contrast, when milling with a CNC milling centre, the tool spins and moves in different directions along one or more axes. A CNC turning centre generally operates on the work surface, so its tooling is more specialised. Conversely, a CNC milling centre comes with more versatile tooling that can perform operations such as drilling and tapping. A CNC turning centre is primarily used for processing shaft-type parts, whereas a CNC milling centre can also be used for processing multiple surfaces, grooves, holes, and curved surfaces.
Which turning tools are generally equipped on a CNC turning center? What are their respective functions?
A CNC turning center is typically equipped with external turning tools, internal turning tools, grooving tools, threading tools, chamfering tools, and cutting-off tools. External turning tools are typically used to machine the external cylindrical surfaces of workpieces, while internal turning tools are commonly used to machine the internal bores of workpieces. Grooving tools are used to machine slots or grooves on workpieces, while threading tools are used to machine external and internal threads on workpieces. Chamfering tools are commonly used to machine the chamfered sections of workpieces, while cutting-off tools are used to cut workpieces from material blocks.
