Vollmer swabian sharpening technology more dependable

Published on : Thursday, May 7, 2020

Vollmer, the developer of grinding and erosion machines extends support and experience to the renowned manufacturer of metal cutting tools, Schrode with their advanced Swabian Sharpening Technology.


Schrode manufactures cutting tools for metals, composites or wood. The company’s list of customers includes companies from the automotive industry, tool manufacturing, mechanical engineering or medical technology. To machine their carbide tools, the toolmaker uses two Vollmer VGrind 360 grinding machines with automation solutions, making true 24/7 unmanned production possible.

“At the core of our company today is a highly motivated team of ten employees, combined with my father’s experience and my youthful enthusiasm,” says Christian Schrode, CEO at Schrode CNC-Werkzeugschleiftechnik GmbH & Co. KG. “Sharpening has been in our blood for five generations, and it has made us a reliable and flexible partner in the fiercely competitive tool-sharpening technology market.”

Schrode’s main strength lies in special tool design


Schrode develops carbide-tipped tools such as milling cutters, drills, step drills and special tools with diameters of 0.2 to 100 millimetres. The batch sizes range from 1 to 5000 pieces. Even during the development of prototypes, the company is able to meet customer requirements quickly and in a targeted manner. The customers predominantly come from the following sectors: Automotive industry, plant engineering, tool-making, mechanical engineering, medical technology, as well as the wood and plastics processing industry.

“One of our strengths is the production of individual special tools that we develop in collaboration with our customers,” adds Christian Schrode. “We believe that it is important that we cover the entire value-added chain when it comes to CNC tool-grinding, i.e from designing the tools and manufacturing, right through to after-sales services, such as regrinding.”

To manufacture their carbide tools, two years ago, Schrode opted to use two Vollmer VGrind 360 tool-grinding machines. With the HP 160 automation solution, Schrode can produce their tools around the clock in an unmanned operation. Thanks to the two vertically arranged spindles, the VGrind 360 enables efficient machining to be carried out on multiple levels, which can reduce non-productive times. Five perfectly harmonised CNC axes achieve interpolation with short travel distances for the linear and rotary axes, which in turn reduces the time required to machine workpieces. It was also important to Schrode that the VGrind 360 is controlled by the NUMROTO software, since the employees are already familiar with this system.

“It is also the smaller tool manufacturers, such as Schrode CNC-Werkzeugtechnik, who can operate more flexibly and efficiently in their markets using our sharpening machines and automation solutions,” says Dr Stefan Brand, CEO of the VOLLMER Group. “Furthermore, thanks to the close proximity to our customers, we can also offer intensive support. Since not all customers are based as close to Biberach as Schrode, we maintain our own sites in 15 countries across the world.”
