Many workshops start by searching for used surface grinders in India or around Ahmedabad. A good second-hand machine can be a bargain. A worn one costs more in scrap parts and lost time than it saved. Prayosha Industries manufactures new machines only. This page will help you judge a used one fairly.
Checklist for a used surface grinder
- Spindle: run it for 20 minutes. Listen for bearing noise and feel the housing for heat. Check run-out with a dial indicator.
- Table ways: look for scoring and wear near the middle of the stroke. Worn ways show as poor flatness on long parts.
- Hydraulics: the table should reverse softly at both ends without jerks. Look for leaks and contaminated oil.
- Feed screws: check the backlash on the cross and vertical handwheels.
- Chuck: test the magnetic hold and check the chuck face for flatness. Re-grinding a chuck costs money.
- Electricals: check the condition of the panel, the motor insulation and the availability of spares.
- Test grind: grind a sample plate and measure its flatness and parallelism.
When a new machine is the better buy
If the used machine needs spindle bearings, way scraping or a hydraulic overhaul, the cost approaches that of a new compact grinder. A new Premier hydraulic surface grinder (PH 818 – PH 1240) comes with known specifications: a 0.002 mm vertical feed least count, imported super-precision spindle bearings, installation help and after-sales service from the manufacturer.

Frequently asked questions
Does Prayosha sell used surface grinders?
No. Prayosha Industries manufactures new surface grinding machines. This page is a guide for buyers who are comparing used and new machines.
What is the most important check on a used surface grinder?
The spindle condition and the table ways. Both are expensive to restore and directly affect finish and flatness.
Is a new entry-level grinder affordable compared with a used one?
It depends on the used machine's condition. Ask for a quotation on a Premier model and compare it with the used price plus any repair cost.
