FAQ's of Hans Sielemann 800 mm Rotary Table type External, Internal & Face Grinder Machine:
Q: How does the Hans Sielemann 800 mm Rotary Table Grinder enhance grinding accuracy?
A: This machine achieves high grinding accuracy (0.003 mm) through precise mechanical construction, stable rotary table technology, and the use of integrated coolant and lubrication systems, reducing thermal influence and vibration during operation.
Q: What types of workpieces can be machined on this rotary table grinder?
A: It is suitable for external, internal, and face grinding of precision components up to 800 mm in diameter and 350 mm in height, with a table load capacity of approximately 800 kg. Typical applications include toolroom components, production parts, and heavy-duty workpieces.
Q: When should I select the magnetic chuck option versus the mechanical chuck?
A: Use the magnetic chuck for holding ferromagnetic workpieces requiring quick fixture changeovers and uniform clamping. Opt for a mechanical chuck when working with non-magnetic materials or when additional clamping force is needed for heavy or irregularly shaped parts.
Q: Where is the Hans Sielemann rotary table grinder primarily manufactured and available?
A: The machine is manufactured in Germany and is available for export and import globally via reliable suppliers, manufacturers, and traders specializing in industrial grinding equipment.
Q: What is the process for operating the grinder for different applications?
A: Depending on configuration, you can use manual or semi-automatic CNC modes. Set up the required chuck type, adjust the grinding wheel and spindle speed, select table rotation and feed rates, and engage the integrated coolant system for optimal surface results.
Q: How does the integrated recirculating coolant system benefit the grinding operation?
A: The integrated recirculating coolant system maintains consistent temperatures during grinding, prevents overheating, flushes away debris, and improves the surface finish of machined parts, all while reducing tool wear and maintaining high precision.
Q: What are the main advantages of using this rotary table grinder in a production environment?
A: Key benefits include high precision and surface quality, robust construction for durability, flexibility in handling various workpiece sizes and materials, automated lubrication and coolant systems, and user-friendly controls that reduce operator fatigue and maximize throughput.
