On a horizontal surface grinding machine, the wheel spindle lies parallel to the table and the periphery of the wheel does the cutting. The table moves back and forth under the wheel, and the cross slide steps the work across after each stroke. This layout gives the best flatness and finish on toolroom and production parts.
Prayosha builds its whole surface grinder range on this layout, as stated for both its PH and ADF series: horizontal spindle, reciprocating table and a column-moving design.
Horizontal vs vertical spindle grinders
| Horizontal spindle (reciprocating table) | Vertical spindle (rotary or segmental) | |
|---|---|---|
| Cutting face | Wheel periphery | Wheel face or segments |
| Best for | Precision flatness, finish, steps, profiles | Heavy stock removal on large batches |
| Profile grinding | Yes, with a dressed wheel | Limited |
| Typical users | Toolrooms, die shops, machine builders | Mass production of simple flat parts |

Manufacturer, supplier and exporter
Prayosha Industries makes horizontal surface grinders at two units in Ahmedabad and supplies them across India through its after-sales network. It also exports to overseas buyers. See surface grinding machine export for shipping and documents.
Frequently asked questions
What is a horizontal surface grinding machine?
A surface grinder whose wheel spindle is horizontal. The periphery of the wheel grinds the work as the table moves back and forth.
Are all Prayosha surface grinders horizontal-spindle?
Yes. Both the PH and ADF series are described by the manufacturer as horizontal-spindle reciprocating-table machines with a column-moving design.
Which horizontal surface grinder should a toolroom buy?
Most toolrooms start with a Premier PH 1224 or PH 1230 (300 mm wide table). Choose a Supreme if you regularly grind die plates wider than 300 mm.
Do you supply horizontal surface grinders outside Gujarat?
Yes, across India and for export.
