Overview

The EMAG CLC 500 H-FR is a large-capacity horizontal CNC profile milling machine designed for precision machining of gear profiles, rotors, and specialized tooth forms on workpieces up to 500 mm (19.5 in) diameter and lengths up to 2,500 mm (98.5 in). As the larger sibling of the CLC 260 H-FR, this machine targets heavy-industry applications including rotor machining for screw compressors, large internal gear profiles, and specialized tooth forms in the module range up to 32 that cannot be produced by conventional hobbing.

The machine accommodates cutter diameters up to 350 mm (14 in) with a maximum profile height of 75 mm (3 in), reflecting the substantially larger tooth forms encountered in heavy-industry applications. The axial travel of 2,000 mm (extendable to 3,000 mm) with a swing-in angle range of +65 to -65 degrees provides the reach and angular flexibility needed for machining deep tooth profiles on long rotor-type workpieces. The generous swing-in range is particularly critical for screw compressor rotor production where complex helical profiles must be machined at steep angles.

The CLC 500 H-FR uses carbide insert milling cutters as standard tooling for the heavy cutting forces encountered in large-module profile milling. The machine supports operation with oil, emulsion, or dry cutting, though oil-based cutting is typical for large-module operations in alloy steel where heat management and tool life are critical. The Fanuc 31iB control manages the complex multi-axis interpolation required for producing precision helical profiles on rotor-type workpieces.

For manufacturers of screw compressor rotors, large ring gears, and specialty tooth forms in the 300-500 mm diameter range, the CLC 500 H-FR is one of very few machines worldwide capable of profile milling at this scale. The combination of 500 mm diameter, 2,500 mm length, module 32, and 75 mm profile height capacity positions the CLC 500 H-FR as the definitive solution for large-scale precision profile milling applications in the compressor, energy, and heavy industrial sectors.

Frequently Asked Questions

01 What applications differentiate the CLC 500 H-FR from the CLC 500 H hobbing machine?

The CLC 500 H is a gear hobbing machine that generates standard involute gear forms through synchronized rotation of the hob and workpiece. The CLC 500 H-FR is a profile milling machine that machines one tooth gap at a time using a form cutter, enabling production of non-involute profiles, screw compressor rotors, and specialty tooth forms that hobbing cannot produce. For standard gear production, the CLC 500 H is faster; for specialty profiles, the CLC 500 H-FR is the only option.

02 Can the CLC 500 H-FR machine screw compressor rotors?

Yes, screw compressor rotor production is one of the primary applications for the CLC 500 H-FR. The machine's 75 mm profile height, steep swing-in angle range, and long axial travel are specifically designed for machining the complex helical profiles of both male and female screw compressor rotors. The Fanuc 31iB control includes dedicated interpolation capability for rotor profile generation.

03 What is the advantage of insert cutters on the CLC 500 H-FR?

At module 32 with 75 mm profile heights, the cutting forces are enormous and tool wear is aggressive. Carbide insert cutters allow operators to index or replace individual cutting edges without removing the cutter body from the machine, reducing downtime between edge changes. Insert cutters also cost less per cutting edge than solid carbide tooling at these large sizes, making them the standard choice for heavy profile milling.

04 What foundation is required for the CLC 500 H-FR?

The CLC 500 H-FR requires a purpose-designed reinforced concrete isolation foundation to handle the significant cutting forces and machine weight associated with large-scale profile milling. EMAG provides detailed foundation specifications during the quotation process, typically requiring 400-600 mm slab thickness with vibration isolation elements. Soil surveys may be required to verify bearing capacity at the installation site.
