5-Axis CNC Machine FAQs

A 5-axis CNC machine moves along three linear axes—X, Y and Z—and two rotary axes. This allows the cutting tool to approach a workpiece from multiple directions and machine complex surfaces and multiple sides in fewer setups.

In simultaneous 5-axis machining, the linear and rotary axes move together during cutting. The coordinated motion helps maintain the required tool orientation on complex contours. DEPU machines use CNC functions such as RTCP on applicable configurations to coordinate multi-axis toolpaths.

The main benefits are fewer setups, improved access to complex surfaces, reduced re-fixturing error, better surface consistency and shorter production time for complex parts. Shorter tools may also be used in suitable applications, which can improve rigidity and tool life.

Start with the maximum workpiece diameter, height and weight. Then compare travel, rotary-axis range, spindle speed and torque, tool interface, tool magazine capacity, CNC control, accuracy requirements and available floor space. DEPU can recommend a configuration based on your workpiece drawings, material and production goals.

The G Series consists of Cradle Type 5-Axis Vertical Machining Centers, while the U Series consists of Vertical and Horizontal Conversion 5-Axis Machining Centers. The G Series uses a cradle-type rotary-table architecture for vertical 5-axis machining. The U Series supports both vertical and horizontal machining orientations for large, heavy and complex multi-sided workpieces. Selection depends on workpiece size, weight, access requirements and machining process.

Provide the workpiece drawing or 3D model, material, maximum dimensions and weight, tolerance and surface-finish requirements, annual volume, required operations, preferred CNC control, tooling requirements and factory space constraints. This information allows DEPU to recommend a suitable machine and options.

The GM130 is a desktop 5-axis micro machining center. Its current page lists education, DIY crafts, jade, machine parts and medical-field applications. It has 300/140/140 mm travel, supports workpieces up to Φ130 × 120 mm and 10 kg, and uses the Chuixiang.AI control system.

The published maximum workpiece size is Φ390 × 250 mm and the maximum uniform load is 50 kg. The suitability of a specific part also depends on fixture size, tool reach, rotary clearance and the programmed toolpath.

The published maximum workpiece size is Φ700 × 400 mm and the maximum uniform load is 850 kg. DEPU should review the complete part and fixture envelope before confirming a machine selection.

The published maximum workpiece size is Φ900 × 500 mm and the maximum uniform load is 1,200 kg. Fixture, tool and rotary clearances must also be considered.

The U1000 supports a published maximum workpiece size of Φ1000 × H1000 mm and a uniform load of 1,800 kg. Its vertical and horizontal machining capability is intended for complex multi-sided parts.

Among the current published models, the U2000 has the highest listed uniform load capacity at 8,000 kg. The U1600 is listed at 4,000 kg, the U1250 at 2,500 kg and the U1000 at 1,800 kg.

Accuracy varies by model, configuration and test conditions. For example, the G300 page lists X/Y/Z positioning accuracy of 0.003 mm, or 0.002 mm with grating feedback, and X/Y/Z repeatability of 0.003 mm, or 0.002 mm with grating feedback. Always use the selected model's technical specification and acceptance conditions for a final accuracy commitment.

DEPU's current website states that it uses ZEISS coordinate measuring systems, laser interferometer calibration and ballbar testing as part of its inspection and calibration process. Do not add other equipment names, accuracy values or acceptance claims unless they are confirmed in the applicable technical specification.

Published configurations include Siemens ONE on the G300 and U1000, and Siemens CNC with RTCP on the G630 and G800. DEPU also states that controller selection can be tailored and mentions Siemens, Heidenhain and Fanuc. Availability must be confirmed for the selected model and market.

Spindle speed depends on the model and configuration. Published standard examples include 24,000 rpm on the G300 and G630, and 10,000 rpm on the G800 and U1000. Some models list optional spindle configurations with different speed and torque ranges.

RTCP, or Rotating Tool Center Point, helps the CNC control maintain the programmed tool-center position while rotary axes move. This supports coordinated 5-axis machining and reduces the need for the programmer to manually compensate for every rotary-axis movement.

Published options on applicable G Series models include Renishaw automatic probing systems, contact or laser tool setters, expanded tool magazines, chip conveyors, coolant filtration and oil-mist collection. Option availability varies by model.
