A bit about the electrospindle Homag

Homag is a German manufacturer specialising in woodworking and composite processing technology. Their electrospindles are known for optimised machining performance, low noise levels, and easy integration with woodworking machinery.

Service scope – what does electrospindle repair include?

During the repair, components such as bearings, rotors, and control systems are diagnosed. Refurbishment also includes replacement of worn parts and precise component balancing to ensure optimal device operation.

Homag electrospindle repair can also include modernisation, allowing devices to be adapted to the latest technological standards. This enables increased machine efficiency and performance.

Typical electrospindle failures and their causes

Homag electrospindles most often experience bearing damage and cooling system problems. Improper maintenance and intensive use can lead to premature wear of these elements. Early symptoms of spindle damage include increased noise during operation, vibrations, and performance drops. Early detection allows quick intervention and prevents serious failures.

Spare parts and precise calibration after repair

Fumak service uses only original components, guaranteeing the highest quality and compatibility with repaired devices. This ensures durability and reliability of the repairs. Accuracy and durability are ensured by procedures such as precise calibration and detailed functional tests. Each device is thoroughly checked for performance, minimising the risk of repeated failures.

Differences between Classic Spindle and Electrospindle Homag

Aspect	Classic Spindle	Electrospindle
Drive	External (e.g., belt-driven)	Built-in motor
Diagnostics	Primarily mechanical	Mechanical + electronic
Sensors/Electronics	None or minimal	Encoders, sensors, control unit
Service Complexity	Low to medium	High – requires specialised tools and knowledge
Balancing	Rotor and shaft	Entire motor-rotor assembly
Spare Parts	Standard	Dedicated, harder to source
Repair Cost & Time	Typically lower	Generally higher – precision and electronics

Summary

Repairing electrospindles Homag requires both mechanical and electronic expertise. With advanced equipment and experienced engineers, we offer comprehensive regeneration services that minimise downtime and extend equipment lifespan.
