Precision Surface Grinding for Enhanced Productivity

The Alpa RT 800 ensures surfaces are ground to a finish of 0.003 mm, thanks to its rotary table and high-precision hydraulic drive. With a minimum increment of 0.005 mm, operators benefit from meticulous adjustment and consistently excellent results across a wide range of metal parts. Its sturdy build and efficient performance make it an asset in high-capacity workshops.

Operator Comfort and Safety Prioritized

This machine is engineered for a quiet operation (<80 dB) and includes automatic centralized lubrication to reduce manual intervention and maintenance downtime. The floor-mounted design offers stability, while integrated coolant and hydraulic systems foster safer, more controllable grinding processes for both experienced and new users.

FAQs of Alpa RT 800 Surface Grinding Machine:

Q: How do I operate the Alpa RT 800 Surface Grinding Machine safely and efficiently?

A: To operate the RT 800 safely, ensure the machine is securely floor-mounted and the magnetic chuck is clean and properly holding your workpiece. Before starting, check the coolant and hydraulic systems. Adjust the rotary table speed to match your material and desired finish, set the grinding increments, and use the manual control system for precise feed adjustments.

Q: What surface finish quality can the Alpa RT 800 achieve on metal parts?

A: The RT 800 can achieve a surface finish as fine as 0.003 mm, ensuring high precision on a variety of metal components. Its rotary table and high-speed grinding wheel enable consistent and smooth results, making it ideal for applications that demand close tolerances and fine finishes.

Q: When should I use the coolant system included with the RT 800?

A: The coolant system should be used during all grinding operations to minimize heat buildup, reduce friction, and extend the life of the grinding wheel. It also helps in achieving better surface finishes and protects both the workpiece and machine from overheating.

Q: Where is the Alpa RT 800 best installed for optimal performance?

A: The machine is designed for floor mounting and requires a dedicated space of 2600 x 2400 mm to accommodate its dimensions and allow easy access for operation and maintenance. Install in well-ventilated workshops with adequate electrical power supply (415 V) and flooring capable of supporting its 3500 kg weight.

Q: What benefits do the hydraulic drive and centralized lubrication system offer?

A: The integrated hydraulic system provides smooth, variable speed control for the table and chuck, enhancing operational precision. Automatic centralized lubrication reduces maintenance time and wear, keeping the machines moving parts in optimal condition and extending its operational lifespan.

Q: How do I maintain the RT 800 for consistent high accuracy and performance?

A: Regularly check and refill the coolant and hydraulic fluid tanks, ensure the automatic lubrication system is functioning properly, and inspect wear parts such as grinding wheels and slide ways. Cleaning the magnetic chuck and workspace after each use will also help maintain ongoing high accuracy and efficient performance.

Q: What types of metal parts can be processed with the Alpa RT 800?

A: The RT 800 is suitable for surface grinding of various metal parts, including large workpieces up to 400 kg. It is commonly used in manufacturing, engineering, and metalworking industries for high precision finishing tasks on components requiring tight tolerances.
