Wandel CNC-Technik GmbH has developed into an established supplier with its own product portfolio over the past 50 years. The Swabian family business, now run in the second generation, has continuously expanded its manufacturing spectrum: from milling to turning to grinding.
Diverse manufacturing spectrum requires flexible technologies
The company, with 23 employees, produces between 15,000 and 20,000 parts monthly. The product range includes forged blanks, drive shafts, and intermediate flanges for the commercial vehicle industry, as well as classic mechanical components such as screw shafts. In the milling area, the focus is on gearbox housings made of aluminum, steel, and cast iron. In grinding, the company concentrates on symmetrical or round parts with diameters ranging from 10 to 150 mm and lengths up to 1,000 mm.
As a proprietary product, Wandel CNC-Technik offers ball screw nuts manufactured in sizes between 16 and 50 mm. These are mainly used in handling technology, for adjusting platforms, and in mechanical engineering.
Targeted investment in grinding technology
The WPG 7 complements the company's machine park as the fourth grinding machine. It was specifically acquired for the processing of flange nuts, where inclined plunge grinding is technologically required. The machine is designed for batch sizes between 20 and 200 pieces and is retooled up to twice daily under high load.
The decision for a dedicated inclined plunge grinding machine was based on several factors: The company already had a straight plunge grinding machine for long and larger components. The compact design of the WPG 7 allows for short travel paths and fast movements – a significant advantage over larger universal machines. The limited space at the location also favored the compact solution.
Technical advantages optimize the production process
A particular advantage of the WPG 7 lies in its thermal stability. The compact design significantly reduces heat transfer, allowing the machine to operate precisely immediately after being switched on. The inclined plunge technology shows its strengths particularly in the processing of flanges that must be ground for squareness or flatness. Compared to earlier processing methods, shorter cycle times and higher quality are achieved.
The modern control of the WPG 7 allows for user-friendly programming directly at the machine, with programs for about 50 different parts stored and retrievable as needed.
Increased efficiency through tailored technology
The investment in the WPG 7 has paid off for Wandel CNC-Technik in multiple ways: The compact design ensures optimal space utilization and thermal stability ensures consistently high quality, while the inclined plunge technology allows for better processing results with flange parts. The short travel paths and ease of operation contribute to increased efficiency, while the quick installation and good support from EMAG enabled a smooth transition into production.
