FAQs of TOS BUA 20 Universal Cylindrical Grinder:
Q: How is the TOS BUA 20 Universal Cylindrical Grinder typically used in a workshop?
A: This machine is primarily used to achieve precise external and internal cylindrical grinding on a variety of components, such as shafts, bushings, and bearing sleeves. Its manual controls and versatile setup options make it ideal for tool rooms, maintenance workshops, and manufacturing applications involving cast iron and steel.
Q: What are the key steps involved in operating the TOS BUA 20?
A: Begin by mounting and securing the workpiece between centers, adjusting the workhead and tailstock as needed. Set up the grinding wheel, select spindle speeds and feeds, and use the manual controls to start the grinding cycle, monitoring coolant flow and lubrication. Fine adjustments ensure dimensional accuracy, and the automatic lubrication system maintains optimal machine condition throughout.
Q: When should the internal grinding function be utilized on this machine?
A: The internal grinding spindle, capable of up to 12,000 RPM, should be used for machining internal diameters or bores within cylindrical parts. It is especially beneficial for applications where high precision and smooth finishes inside housings, rings, or bushings are required.
Q: Where can the TOS BUA 20 be installed and what space considerations are needed?
A: Being a floor-mounted machine, it is suitable for use in industrial workshops, tool rooms, and manufacturing facilities. The machine requires a space at least 2200 x 1600 mm with adequate overhead clearance and a stable, level floor capable of supporting its 2200 kg weight.
Q: What are the advantages of its automatic lubrication and coolant systems?
A: The automatic lubrication system ensures continuous, even distribution of lubricant to critical components, reducing wear and minimizing downtime. The integrated coolant system keeps the grinding process thermally stable, extending both workpiece and wheel life, and improving surface finish quality.
Q: How can the workhead and table adjustments benefit complex grinding tasks?
A: The adjustable workhead and the 7 table swivel range allow operators to set up the machine for both straight and angular grinding operations, accommodating a wide variety of part geometries. This flexibility leads to accurate results and reduced setup times, especially for unique or intricate component shapes.
