Frequently Asked Questions
What is the difference between GSS-400 and GSS-500?
The GSS-500 uses a 125 mm diamond grinding wheel with a longer lifespan compared to the GSS-400.
It supports blades up to 500 mm and offers greater stability thanks to its weight of 18.48 kg, while the GSS-400 is lighter and suitable for occasional use.
How long does the diamond grinding wheel last?
The average lifespan is 2–3 years with regular use.
With approximately 100–150 sharpenings per year, the grinding wheel maintains constant precision, reducing costs compared to traditional abrasive discs.
Is it suitable for hard steels?
Yes, the 150 W motor with controlled speed is suitable for hard steels.
The reduced speed limits overheating, preserving the temper of the blades during the sharpening process.
Do the adapters cover all blades?
The included adapters cover bore sizes from 10 to 30 mm.
For non-standard diameters, specific compatible adapters must be purchased separately.
Does it require three-phase power?
No, it operates with standard 230 V single-phase power.
It can be used in any workshop or laboratory without the need for a three-phase industrial system.
