KLINGELNBERG will present its gear manufacturing and measuring technology at IMTEX 2027, the machine tool and manufacturing technology show held at the Bangalore International Exhibition Center (BIEC) in Bengaluru, India, from 21 to 27 January 2027. The company’s announcement of 9 November 2026 highlights gear noise reduction, in-line quality control and the digital use of production data.
Tackling bevel gear noise at the grinding stage
Quiet Bevel Grinding on the G 30 is designed to improve the noise behaviour of ground bevel gears. A low-frequency harmonic variation in the machine kinematics, applied from tooth space to tooth space, modifies the topography of each tooth flank individually. Instead of concentrating at one frequency, the sound energy is spread across several, producing what the company describes as a multi-frequency sound similar to lapped gear sets. KLINGELNBERG says the method does not change cycle times, does not interfere with gear measurement and works with the existing Closed Loop system.
100 percent testing in the line and measuring in one setup
The Höfler R 300 cylindrical gear roll testing machine is built to find the root causes of noise resulting from poor gear quality. Its short measuring time allows it to be integrated into production for 100 percent quality control. It supports single flank, structure-borne noise and torsional acceleration testing, with double flank testing available if required. Depending on its equipment, it can test both gears and shafts, which makes it relevant for eDrive drivetrains; data is evaluated with the Gear Noise Analyzer (GNA) software.
The fully automatic, CNC-controlled P 40 precision measuring center handles workpieces up to 400 mm in diameter, including cylindrical gears, cutting and shaving wheels, worms and worm gears, hobs, bevel gears, camshafts and rotors. Integrated temperature compensation is intended to give reliable results at ambient temperatures of +15 °C to +35 °C, and coordinate, form, gear and roughness measurements can be carried out in a single setup.
Digital tools from production data to tool management
Digital solutions complete the line-up. Data-Driven Quality Management (DDQM) links production data to control final workpiece quality and to identify problems before parts leave the shop floor. The web-based Smart Tracing software uploads and evaluates servo traces across common CNC control systems, checks signals against tolerances, supports predictive maintenance and is not limited to KLINGELNBERG machines. Smart Factory combines IoT, AI and real-time data analytics, while Blade Management creates a digital twin for each production tool, such as stick blades and cutter heads, recording status, usage history, settings and remaining service life. Tooling and clamping systems will also be on display.
