Faster finishing and prefinishing with circle-segment cutters
Smooth surfaces with large path distances
For circle-segment cutters – also known as barrel cutters – the radii in the cutting areas are significantly larger than for conventional ball cutters. They are modern high-performance tools for high-efficiency prefinishing and finishing of planes and free-form surfaces. The same surface roughness is achieved on the part with a significantly larger path distance, which greatly reduces your machining times while achieving outstanding surface quality.


In this example, circle-segment and ball cutters have the same diameter of 10 millimeters. However, the circle-segment cutter has a radius of 250 millimeters in the cutting area, while the ball cutter has a radius of only five millimeters
Comparison of machining with circle-segment cutters and ball cutters
- Efficient – Time savings of more than 80 percent
- Versatile – Tebis supports all types of circle-segment cutters
- Comprehensive – Suitable for 3-axis tilted and 5-axis simultaneous machining
Tebis is suitable for all types of circle-segment cutters
Which circle-segment cutter is best suited for finishing depends entirely on the specific manufacturing task. The significant advantage of Tebis: You can directly import most manufacturer’s tools with the according contours. And by using parameters or curves, you can create all tool geometries quickly and easily and represent them on a 1:1 basis in the tool library. You remain completely flexible

Optimal for 3 and 5-axis machining
Circle-segment cutters are suitable for both 3-axis tilted machining as well as for 5-axis simultaneous machining. You gain a double speed advantage from Tebis in 5-axis machining: With no additional design overhead, you can select multiple surfaces with a simple mouse click and machine them with high-performance circle-segment cutters.
