Rebuild for VL 3, VL 5, and VL 5i: How Machine Precision is restored in a predictable manner

by Oliver Hagenlocher 21. July 2026

A rebuild mechanically restores a proven VL machine to reliable production-ready condition. Instead of accepting declining precision, increasing downtime risks, or diminishing performance, the machine undergoes a targeted overhaul. For operators of the VL 3, VL 5, and VL 5i, this provides a predictable alternative to purchasing new equipment. 

In batch production in particular, it’s not just machine availability that counts. What matters most is that the system produces with consistent precision, maintains stable cycle times, and avoids unplanned downtime. With a professional rebuild,  key mechanical assemblies are replaced or overhauled, restoring the machine to original precision  and continued to use productively.

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.

Manufacturing of ball tracks in joint housings: Precision machining with VSC technology

by Oliver Hagenlocher 26. May 2026

Joint housings are among the most technically demanding components in automotive drivetrains. Together with inner races, ball cages, and outer races, they form the basis for CV joints, which enable uniform power transmission between two axles—even with varying angles and length compensation. The manufacturing quality of the ball tracks in these components directly determines the functionality, smoothness, and service life of the entire drivetrain.

Rotor shafts for electric drives: Why quality requirements are rising – and which designs have become established

by Oliver Hagenlocher 11. May 2026

With the rise of electric mobility, the focus in manufacturing is shifting significantly: Components that could “run along” in internal combustion engines due to masking noises and vibrations are evaluated much more critically in electric drives. The reason is simple: The internal combustion engine generates a broad spectrum of noise that masks many background sounds. In electric drives, this acoustic “background noise” is largely absent, making deviations in shape, position, and surface significantly more noticeable.

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.

High-precision complete-machining of Wave Generator for Harmonic Reducer on the VLC 350 GT

by Oliver Hagenlocher 30. March 2026

Wave generators are central drive elements in strain wave gears, which are used in robotics in particular due to their high reduction ratios and compact design. The component consists of a ball bearing with an elliptically shaped outer ring, which is mounted on a shaft and typically acts as the input side of the gearbox. 

Producing these components presents significant technical challenges for manufacturers: The required shape tolerances in the single-digit micrometre range combined with complex elliptical geometries and thin-walled structures require specialized manufacturing strategies and highly capable machine tools.

The new EDNA Feature Correction and EDNA Production Status apps

by Oliver Hagenlocher 17. February 2026

Experience the new generation of EDNA Feature Correction and EDNA Production Status.
EDNA Feature Correction is a core component of EDNA ONE and enables the manual or automatic adjustment of production features in real time. This ensures that product quality remains stable over the long term and process deviations can be corrected immediately.
EDNA Production Status is a central module of EDNA ONE and displays the current status of a machine as well as the overall production progress in real time. Operators receive a clear overview of active programs, upcoming work steps and possible downtimes. This makes machine operation more transparent, reaction times are reduced and production can be controlled much more efficiently.

VT 200 with counter spindle: Process integration in CNC lathes for compact production lines

by Oliver Hagenlocher 5. February 2026

The manufacturing industry faces the challenge of using production space more efficiently while also reducing process times. When machining flange parts, such as differential housings, several separate machining stations are required in conventional production. The VT 200 with counter spindle option shows how modern turning machines can address these challenges through process integration.
