This article will explore various aspects of acquiring such advanced machinery, including factors influencing purchasing decisions, different types available in the market, and considerations for installation and maintenance.
1. Machine Configuration
Machine configuration is a critical factor when considering 5-axis CNC machines. The specific arrangement of the five axes significantly impacts the machine’s capabilities, determining the types of parts it can produce and the efficiency with which it can produce them. Selecting the appropriate configuration requires careful consideration of the intended applications and desired production outcomes.
-
Table-Table (TT) Configuration
In a TT configuration, both the workpiece and the cutting tool rotate. This configuration is well-suited for machining large, heavy parts, as the workpiece remains stationary on the table, minimizing the load on the rotary axes. For example, large aerospace components or automotive molds benefit from this configuration. However, the limited range of motion of the cutting tool may restrict access to certain areas of the workpiece.
-
Head-Head (HH) Configuration
HH configurations have both the spindle head and the table capable of rotation. This allows for greater flexibility in tool orientation and access to complex part geometries. This is ideal for intricate parts such as impellers or turbine blades. However, the size and weight of the workpiece are limited by the table’s capacity.
-
Table-Head (TH) Configuration
TH configurations combine a rotating table with a tilting or swiveling spindle head. This offers a balance between workpiece capacity and tool maneuverability. This setup is commonly used for general machining applications, offering versatility for a range of part sizes and complexities, although it may not excel in the extremes of either TT or HH configurations. This configuration is frequently seen in smaller 5-axis machines due to its cost-effectiveness.
-
Trunnion Table Configuration
The trunnion table configuration involves mounting the workpiece on a rotary table that can rotate around two axes. This provides excellent access to multiple sides of the workpiece without requiring re-fixturing. This configuration is favored for prismatic parts requiring machining on multiple faces, increasing efficiency and reducing setup times.
Understanding these different configurations is essential for selecting a 5-axis CNC machine that aligns with specific manufacturing needs.
