User-Friendly and Manual OperationWith intuitive manual controls-including fine graduations for cross and vertical feed-the machine allows for precise adjustments. Operators benefit from straightforward setup and easy handling, ideal for industrial workshops seeking reliable performance without the complexity of CNC systems.
Efficient Lubrication and Cooling SystemAutomatic centralized lubrication and a powerful coolant pump help maintain smooth operation and enhance machine longevity. This ensures reduced maintenance needs and optimal performance even in high-use manufacturing environments.
FAQ's of ZVL TOS BRH-20A Surface Grinding Machine:
Q: How does the ZVL TOS BRH-20A ensure precise surface grinding results?
A: The BRH-20A features highly accurate manual feed graduations (0.02 mm cross, 0.005 mm vertical) and robust V-flat guideways. Its rigid cast-iron build and high-speed spindle further contribute to achieving precise surface finishes as fine as 0.5 m Ra.
Q: What materials and workpiece sizes can the BRH-20A handle?
A: This machine is suitable for grinding various metals and is constructed to accommodate workpieces up to 500 x 200 mm on its magnetic chuck. The maximum distance from table surface to spindle center is 370 mm, making it versatile for many industrial tasks.
Q: When should the centralized lubrication system be serviced?
A: While the machine's automatic centralized lubrication minimizes manual maintenance, it's advised to check lubricant levels regularly (e.g., weekly or after heavy use) and refill the approx. 50-litre tank as needed to ensure optimal performance.
Q: Where is the BRH-20A most commonly used?
A: This model is designed for industrial environments, including manufacturing workshops, tool rooms, and facilities in sectors requiring high-precision surface grinding. Its durability and reliability make it suitable for exporters, importers, and suppliers alike.
Q: What is the process for adjusting grinding speed and feed rates?
A: Operators can adjust working speed and manual feed via control handwheels. Step graduations allow precise table and wheel positioning for different material requirements, and the variable speed ensures adaptability to specific grinding tasks.
Q: What benefits does the BRH-20A offer over CNC grinders?
A: While it is manual and not CNC, the BRH-20A offers simplicity, lower maintenance, and cost-effectiveness. Its manual control and high precision are ideal for applications where nuanced operator input and flexibility are paramount.
