Precision and reliability in valve grinding machines
A valve grinding machine, or valve refacer, restores the sealing face of intake and exhaust valves during cylinder-head reconditioning, a key step for engine compression and reliability.
Our equipment is carefully selected to meet the needs of professional workshops, offering high-quality tools for the grinding and resurfacing of valves in automotive, motorcycle, industrial and marine engines.
All machines are supplied new, with technical support and worldwide delivery.
How to choose an engine valve grinder
The right valve grinder depends on the type of work your workshop handles. The main criteria to consider are:
- Valve size: check the maximum valve head diameter and stem diameter you need to machine: standard automotive valves differ greatly from large marine or industrial ones.
- Engine type: cars and motorcycles, heavy vehicles, or naval and industrial engines call for different capacities.
- Grinding system: centerless systems ensure perfect valve alignment and minimal runout, while spindle-driven machines suit larger valves.
- Precision and productivity: grinding accuracy, wheel options and ease of use affect both quality and throughput.
- Budget and value: balance purchase price against capacity, build quality and available accessories.

Frequently asked questions
What is a valve grinding machine?
It is a workshop machine that grinds the valve face (and often the stem tip) to restore a precise sealing angle during engine reconditioning, also known as a valve refacer.
What is the difference between a valve grinding machine and a valve seat grinder?
A valve grinding machine reconditions the valve itself, while a valve seat grinder or cutter machines the seat in the cylinder head. The two operations are complementary.
Is a centerless valve grinder better?
A centerless system holds the valve on its stem with minimal contact, ensuring excellent concentricity and repeatability. It is ideal for high-precision automotive work; spindle-driven machines remain preferable for very large valves.
Do you also offer used valve grinding machines?
Yes. Alongside new machines, you can browse our used valve grinding machines for sale, subject to availability.
