Both rotary and reciprocating surface grinders produce flat, precise faces — but they get there differently, and the right choice depends on your part and your priorities.
How they differ
Reciprocating surface grinders move the workpiece back and forth beneath the wheel on a reciprocating table. They excel at precision flat grinding, slots, and profiles, and are the go-to for tool rooms, dies and molds, and mixed-batch work where accuracy and finish come first.
Rotary surface grinders hold parts on a continuously rotating magnetic table. Because parts pass under the wheel continuously, rotary machines shine when productivity matters alongside finish — think higher-volume production of flat components.
Choosing between them
- Prioritize surface finish and flatness on varied parts? A reciprocating grinder sized to your component is ideal.
- Prioritize throughput on flat production parts? A rotary grinder (horizontal or vertical spindle) keeps parts moving through the grind zone.
- Large or heavy components? Look to high-HP rotary or heavy-duty reciprocating machines.
