Factory Tour

Inside Our Gear Motor Plant

Follow a gear motor from raw bar stock to the shipping dock. Every station below is a real line in our workshop, with the equipment and tolerances we run it at.

CNC turning center machining a gear blank from steel bar stock

Step 01

Precision Gear Turning

Equipment: Mori Seiki CNC turning center

Bar stock is cut, centered and turned into gear blanks on a fully enclosed CNC turning center. Every blank is probed in-cycle, so dimensional drift is caught at the machine instead of three stations later.

Gear accuracy
DIN Grade 6
Cycle time
45 s / pc

Step 02

Tooth Grinding & Heat Treatment

Equipment: Reishauer continuous gear grinder

Blanks are carburized, quenched and tempered before the tooth flanks are ground to final geometry. Grinding after heat treatment is what keeps the gear quiet under load for the full service life.

Step 03

Automated Rotor Assembly

Equipment: KUKA 6-axis robots + servo presses

Rotors, bearings and gear sets are press-fitted by servo presses under closed-loop force monitoring. Each press curve is logged against the serial number, so any unit can be traced back to its assembly signature.

Press-fit accuracy

Automation rate

Step 04

100% Performance Inspection

Equipment: ZEISS CMM + motor test benches

No gear motor leaves the line on a sampling plan. Every unit runs a full load, temperature-rise and noise test, and the report ships with the order so your incoming QC has something to check against.
