A surface grinder exists to make other parts accurate, so its own geometry has to be right first. Prayosha follows a quality management system and says it adheres to strict quality norms through each build stage.
Testing standard
According to the manufacturer, machines are tested as per IS 2743 and ISO standards. IS 2743 is the Indian Standard for testing the accuracy of surface grinding machines with a horizontal spindle and reciprocating table. It covers table flatness, the straightness of the travels, spindle run-out and the parallelism of the table to the wheel path.
What gets checked
- Incoming castings and bought-out parts
- Machined guideways and slide fits
- Spindle assembly and run-out
- Hydraulic system pressure, leakage and smoothness of reversals
- Geometric accuracy of the assembled machine
- Test grinding before dispatch
Research and development
Prayosha has set up a research and development department that works on new models, larger capacities and CNC features such as profile grinding and automatic dressing compensation.
