Vertical turning and grinding center for the precision machining of chucked components

by Oliver Hagenlocher 30. June 2026

In small chucked component production, demands for precision and cost-effectiveness are on the rise. Gear wheels, planetary gears, sprockets, cam rings, pump rings, individual cams, or shaft generators must be precisely finished after hardening. Tight dimensional and geometric tolerances, stable positional relationships, and defined surface qualities are required for high-volume production.

The VL 100 GT from EMAG is designed for this task. The vertical turning and grinding center combines hard turning and grinding in a single machine and enables high-precision finishing of small chucked components up to 100 millimeters in diameter in a single setup. This reduces reclamping errors, shortens process times, and achieves the required surface quality.

Precision Machining in High-Volume Production: The Manufacturing Process Chain for Steering Pinions

by Oliver Hagenlocher 4. May 2026

The production of steering pinions poses a particular challenge in the modern automotive industry. These precision gear components are indispensable parts of steering systems and must meet the highest quality standards while also being produced economically in large quantities. The combination of required dimensional accuracy, surface finish, and process stability demands specialized manufacturing solutions. 

In this interview, Konstantin Ungefuk, Head of the Gear Cutting Soft Business Unit at EMAG, explains the complex process chain involved in machining steering pinions. He provides detailed insights into every machining step – from turning the raw-parts to soft-state gear hobbing, precision grinding of the bearing seats after hardening, and the final skiving of the hardened tooth profiles.

Cylindrical grinding rethought: W 11-EVO combines manual expertise with digital precision

by Oliver Hagenlocher 13. March 2025

“The combination of manual operation and automated functions allows operators to make the most of their experience while benefiting from the precision of the control system,” explains Andreas Hessling, Technical Sales Manager at EMAG Weiss, in an interview. The hydraulic-free W 11-EVO cylindrical grinding machine addresses key customer requirements: minimized energy costs thanks to servo-electric axes, highest precision thanks to scraped V-flat guides and an intuitive touch control for quick machine settings. The sophisticated operating concept shows its strengths particularly in the economical production of prototypes and individual parts. The operator retains direct control over the sanding process thanks to handwheels, while the servo-controlled axes ensure precision positioning and reproducible results.
