Applications & Suitable Workpieces

The used TAIYO KOKI NVG-5L vertical grinder is suitable for manufacturers that need accurate ID, OD and face grinding of medium to large rotational components.

Typical applications include:

Internal diameter grinding of precision bores and cylindrical components
External diameter grinding of rings, sleeves and rotational parts
Face grinding where perpendicularity and dimensional accuracy are important
Precision grinding of bearing components
Grinding of gear-related components and transmission parts
Machining of large rings, flanges and sleeves
Precision finishing of automotive and industrial components
Production of components requiring tight roundness and dimensional tolerances
Heavy workpieces where a vertical grinding configuration provides easier loading and stable support

The vertical machine configuration is particularly useful for heavier circular workpieces because the workpiece is supported by gravity rather than being suspended horizontally.

Why Consider This Used TAIYO KOKI NVG-5L?

When a factory needs additional precision grinding capacity, purchasing a new Japanese vertical grinder can involve a significant capital investment and long delivery cycle.

This pre-owned TAIYO KOKI NVG-5L CNC vertical grinder provides an alternative for buyers who want established Japanese machine-tool technology while controlling equipment investment.

The machine is equipped with a FANUC Series 32i CNC control and provides both internal and external grinding capability for workpieces up to approximately Ø550 mm.

Its combination of a 500 kg workpiece capacity, 1 μm stated roundness specification, 0.0001 mm minimum feed increment and high-speed grinding spindle makes it especially relevant for precision component manufacturers, machine shops and factories upgrading their cylindrical grinding capacity.
