Overview
The Klingelnberg Vario 180 is a flexible CNC gear manufacturing machine for cylindrical gears up to 180 mm (7.1 in) outside diameter. The Vario platform distinguishes itself from conventional dedicated gear cutting machines by combining gear hobbing and gear grinding capability in a single machine setup — a significant flexibility advantage for precision cylindrical gear production where both soft-cutting and hard-finishing operations are required.
The Vario concept allows the same machine to perform gear hobbing of pre-hardened blanks and continuous generating gear grinding of case-hardened gears, with tooling changeover between operations. This single-machine versatility eliminates the need for a separate hobbing machine and gear grinder in lower-volume or highly flexible production environments, reducing capital investment and floor space requirements.
At 180 mm maximum workpiece diameter and maximum module 5, the Vario 180 targets precision gearbox, servo drive, and specialty automotive gear production. The machine's quality capability in gear grinding mode reaches DIN 3-4, which meets aerospace and high-precision industrial gear requirements. The direct-drive workpiece and tool spindles maintain this quality level across both hobbing and grinding operations.
Klingelnberg's software platform on the Vario 180 provides process-integrated programming for both hobbing and grinding cycles, with topology modification capability for noise-optimized gear grinding. Integration with Klingelnberg's P-series cylindrical gear measuring centers enables closed-loop correction for both processes. New Vario 180 machines are typically priced in the $700,000-$1,100,000 range.

Strengths & Limitations
Strengths
- Combined hobbing and grinding in a single machine eliminates the need for two separate machines and two setups for cylindrical gear manufacturing — capital and floor space savings
- DIN 3-4 grinding quality meets aerospace and high-precision industrial gear specifications without requiring a dedicated gear grinding machine
- Klingelnberg's topology grinding capability supports engineered profile and lead modifications for NVH-optimized precision gears
- Flexibility to hob new gear types or re-grind existing gears in the same machine makes the Vario 180 well-suited for high-mix, lower-volume precision gear production
Limitations
- Maximum module 5 and 180 mm diameter limits the Vario 180 to smaller precision gears — larger gear production requires dedicated hobbing and grinding platforms
- Cycle time for combined hobbbing and grinding in one machine is longer than optimized dedicated machines — high-volume production of a single gear type is better served by dedicated platforms
- Price of $700K-$1.1M is higher than either a dedicated hobbing machine or a dedicated gear grinder of similar capacity — the premium is justified only when flexibility value outweighs throughput optimization

Frequently Asked Questions
01
The Vario 180 is designed for combined hobbing and grinding capability, but the tooling changeover (from hob arbor to grinding wheel spindle) requires a machine setup change between the two operations. Hobbing and grinding are not performed simultaneously. The advantage is that both operations use the same workpiece fixturing and machine datum, reducing setup error between soft-cutting and hard-finishing operations. This is different from a true single-setup operation but still provides significant flexibility compared to transferring parts between separate machines.
02
In hobbing mode, the Vario 180 achieves DIN 6-7 quality (AGMA 10-11) in production conditions, consistent with high-quality gear hobbing on dedicated hobbing machines. This pre-hardening quality determines the grinding stock remaining for the subsequent grinding operation. The Vario 180's direct-drive spindles and Klingelnberg's process software maintain hobbing accuracy that minimizes grinding stock, reducing grinding cycle time and wheel consumption.
03
The Vario 180 is primarily configured for continuous generating gear grinding with a grinding worm, which is the highest-productivity grinding method for production quantities. Profile grinding (grinding individual tooth spaces with a form wheel) is used for gears that cannot be produced by generating grinding (e.g., gears with interference from adjacent features). Contact Klingelnberg to confirm profile grinding availability on the specific Vario 180 configuration.
04
KAPP NILES KX machines are dedicated gear profile grinders optimized for high-volume production of a single process (grinding). The Vario 180 is a combined hobbing and grinding machine optimized for flexibility. For high-volume production of a single gear type, dedicated KX grinders will have better throughput and cost-per-gear. For high-mix production or shops that need both processes in limited floor space, the Vario 180 provides capabilities that two separate machines would otherwise require.
05
Klingelnberg's Vario platform may be available in multiple size configurations. The Vario 180 covers up to 180 mm diameter. Contact Klingelnberg for information on larger Vario configurations if your gear range exceeds 180 mm. For large-diameter precision gears above 180 mm, Klingelnberg's dedicated hobbing and grinding platforms (or third-party equipment) are the standard solution.
