In northern Germany, a young Hunter Velonsen used his savings to open a repair shop of less than 30 square meters on the outskirts of town. Specializing in Horch gearbox repairs, his precise hand-grinding technique earned him a local reputation. Even during the 1929 Great Depression, he insisted on using precision Swiss gauges—sacrificing 20% of his profits to preserve accuracy.
After WWII, his son Karl Velonsen took over the half-destroyed workshop. He repurposed scrap 88mm anti-aircraft gun barrels into lathe spindles and sketched designs with colored pencils salvaged from church ruins. His improvised multi-size wrench—fitting American,British, and German bolts—was born when a U.S. jeep bolt jammed. In 1949, during the Berlin Blockade, these tools, forged from artillery shells, were airlifted west. The engraved “V” became a symbol of quality.
The third-generation Wolfgang Velonsen faced a turning point. During the 1972 Munich Olympics, he urgently produced reinforced suspension parts for athlete buses, catching BMW’s attention. This led to his first CNC machine purchase and the factory's shift to parts manufacturing. The wall still bears the handwritten note: “BMW Order: 200 sets, Tolerance ±0.02mm.”
CEO Martin Velonsen’s toughest
decision was retiring
his grandfather’s old gantry planer.
Though still functional,
it was inefficient. His digital system
faced resistance
until it proved it could detect bearing wear
15 minutes early.
The old planer is now kept to
teach new hires
about true flatness precision.
From 1923’s copper bolts to 2024’s 3D-printed
titanium parts, all fit perfectly. Defective samples
from each era are stored with notes. Supervisor Schroder
shows the "Standard Parts Box" spanning four generations.
"Our parts still mesh with those from 1923.
Gears never lie—they speak to those who understand."
