FAQ's of TOS Hostivar BHU 25-1000 Universal Cylindrical Grinder:
Q: How do you operate the TOS Hostivar BHU 25-1000 cylindrical grinder?
A: The machine features manual controls for all grinding processes, with optional electrical controls for enhanced convenience. Operators can set up the workpiece using centers or a 3-jaw (optional 4-jaw) chuck and select appropriate spindle speeds from 25 to 500 RPM. The grinding process is supported by an integrated coolant and centralized lubrication system to maintain consistency and finish quality.
Q: What types of workpieces can be ground on this machine?
A: This grinder is designed for precision grinding of cylindrical workpieces with a maximum diameter of 250 mm, length of 1000 mm, and weight between centers up to 250 kg. It's suitable for both external and internal surfaces, especially for components constructed of hardened steel or similar materials.
Q: When should the integrated coolant and lubrication systems be used?
A: Both the coolant and centralized lubrication systems should be continuously engaged during operation to enhance grinding accuracy, prolong tool life, and maintain dimensional stability of the workpieces, as well as to reduce wear on machine components.
Q: Where is the TOS Hostivar BHU 25-1000 manufactured and by whom?
A: The BHU 25-1000 universal cylindrical grinder is manufactured in the Czech Republic. It is available globally through exporters, importers, manufacturers, suppliers, and traders specializing in high-precision industrial machinery.
Q: What is the process for internal grinding on this machine?
A: To perform internal grinding, operators can install the optional internal grinding attachment. The workpiece is mounted between centers or in a chuck, and the attachment enables precision grinding of internal diameters, complementing the machine's external cylindrical grinding capabilities.
Q: How does the centralized lubrication system benefit the machine?
A: The centralized lubrication system ensures even and consistent distribution of lubricant to all critical moving parts, reducing friction and wear. This extends the lifespan of the grinder, enhances performance reliability, and minimizes maintenance requirements.
Q: What are the primary benefits of using the TOS Hostivar BHU 25-1000?
A: Users benefit from robust construction, precision-ground tableways, an adjustable wheel head, and versatile grinding functions for both external and internal surfaces.
