FAQs of Jones and Shipman 540P Precision Surface Grinder:
Q: How do I operate the Jones and Shipman 540P surface grinder for consistent results?
A: To achieve optimal performance, position your workpiece securely on the magnetic chuck, select the desired table feed (manual or optional power), and set the vertical feed increment precisely using the hand-operated controls. The integrated coolant and automatic lubrication systems help maintain smooth operation and consistent surface finish.
Q: What types of magnetic chuck systems are available and how do I choose between them?
A: The 540P is compatible with both electromagnetic and permanent magnetic chucks, offering flexibility depending on workpiece size and holding requirements. Electromagnetic chucks allow for easier part removal and greater holding strength, while permanent chucks provide reliability without relying on power.
Q: When should regular maintenance be performed on the grinder?
A: Maintenance should follow the manufacturers guidelines, typically including inspection of lubrication levels, cleaning of coolant systems, and checking the condition of grinding wheels after each work cycle. The automatic lubrication system simplifies upkeep, but periodic checks ensure long-term accuracy and reliability.
Q: Where can I use the Jones and Shipman 540P surface grinder effectively?
A: This grinder is widely used in precision engineering workshops, job shops, tool rooms, and manufacturing units. Its compact floor space and reliable UK-made design make it suitable for institutions requiring high-quality surface grinding in moderate volumes.
Q: What process is followed to obtain a surface finish of 1.6 Ra m or better?
A: Begin by selecting the appropriate grinding wheel and confirming that the coolant system is active. Make incremental vertical passes of 0.01 mm, utilizing steady hand or powered table movements. Proper setup and slow, controlled feeds enable the desired fine surface finish.
Q: How does the integrated coolant and lubrication system benefit my operation?
A: The built-in coolant system minimizes heat buildup, preserving both machine and workpiece integrity. The automatic lubrication system reduces friction and wear on moving parts, extending the grinders service life and ensuring consistent, high-precision output with less manual intervention.
