| Tilting rotary-table center |
Three linear axes plus two rotary axes in a tilting rotary table, often described as a trunnion-style arrangement. |
Small to medium parts that can be securely mounted on a rotary table. |
Impellers, turbine components, dies, molds, and precision parts with features on multiple sides. |
Can provide access to several faces in one setup; often suited to compact, complex components. |
Check table load, rotary-axis travel, workpiece size, and whether the part can clear the table throughout its motion. |
| Swivel-head center |
Three linear axes plus two rotary axes carried by a tilting or swiveling spindle head. |
Medium to large parts, including workpieces that are difficult to place on a tilting table. |
Aerospace structural parts, large molds, and components requiring angled or multi-face machining. |
The workpiece can remain fixed on the machine table while the tool approaches from different angles. |
Review head angular range, tool access, spindle performance at different angles, and the effect of head movement on usable workspace. |
| Table-and-head center |
One rotary axis in the table and one in the spindle head, in addition to the three linear axes. |
Parts requiring a mix of table rotation and angled tool access. |
Complex components with deep cavities, compound angles, or features distributed across multiple faces. |
Combines workpiece rotation with tool-angle adjustment, which can improve access for some part geometries. |
Confirm the machine’s rotary-axis limits, collision-clearance envelope, and postprocessor support for the intended toolpaths. |
| 5-axis gantry center |
Three linear axes on a gantry structure, usually with two rotary axes in a swiveling spindle head. |
Large or long workpieces that need a broad machining envelope. |
Aircraft structures, large molds, energy-sector components, and other large-format parts. |
Designed to accommodate large work envelopes and can machine multiple surfaces of a large part. |
Compare the actual working volume, allowable workpiece mass, head configuration, foundation requirements, and accuracy specifications. |
| Horizontal 5-axis center |
Horizontal spindle with two rotary axes commonly provided by a rotary or tilting workholding arrangement. |
Parts suited to horizontal machining and multi-side access, often with demanding chip-management needs. |
Gearbox housings, pump bodies, structural components, and other parts with features on several sides. |
Horizontal orientation can help chips fall away from the cutting area; suitable configurations can support multi-face machining. |
Check fixture access, rotary-axis range, chip evacuation, tool reach, and whether the machine supports the required simultaneous motion. |
| 3+2 positional machining |
Two rotary axes position the workpiece or tool at an angle; the three linear axes then perform the cut. This is a machining mode, not a separate machine layout. |
Parts with several angled faces that do not require continuous rotary-axis motion during cutting. |
Prismatic parts, angled holes, pockets, and multi-face machining where each feature can be approached from a fixed orientation. |
Can reduce repeated setups and simplify programming for suitable parts. |
Do not assume 3+2 positioning is the same as simultaneous five-axis cutting; verify the control, software, and process requirements. |
