Analysis of the Structure and Use of CNC Turret Lathe Turret Systems

A turret lathe is a type of CNC lathe that uses a turret device to automatically switch between multiple tools. Its core feature is the ability to perform continuous multi-process machining under a single clamping condition, through the rotation, positioning, and locking of the turret, thereby improving processing efficiency and consistency. CNC turret lathes have become a common type of equipment for small and medium-batch, multi-variety parts processing.

The turret not only determines the machining flexibility of the machine tool but also directly affects machining accuracy, tool change speed, and overall machine stability. Therefore, different types of turret structures and configurations are suitable for different machining scenarios.

Introduction to Existing Turret Types and the Types and Structures of CNC Turret Lathes

1. Turret Types Classified by Function

(1) Ordinary Turret (Fixed Tool Turret)

Ordinary turrets are mainly used for installing turning tools and do not have power output capabilities. They are suitable for the following machining methods:

• External turning
• Face machining
• Cutting off, grooving
• Thread turning

Its structure is relatively simple, and maintenance costs are low, making it suitable for parts processing primarily involving turning.

(2) Powered Milling Turret (Powered Turret)

Powered milling turrets add a power transmission system to the ordinary turret, allowing the tool to rotate, enabling:

• Drilling
• Face milling
• Keyway milling
• Tapping

Powered milling turrets significantly expand the machining capabilities of CNC lathes, giving them certain multi-functional machining capabilities.

2. Turret Types Classified by Structural Form

(1) Integrated Turret

• Turret body integrated with power and locking system
• Compact structure
• Relatively stable installation accuracy
• Suitable for standardized machine tool configurations

(2) Split Turret

• Turret and power system are separated
• Easy for maintenance and partial replacement
• Flexible structure, adaptable to customized needs

(3) Lifting Turret

• The turret lifts axially or radially during tool change
• Reduces tool change interference
• Commonly used in machine tools with limited space or high-density tool positions
