Operators can precisely adjust vertical feed (0.005 mm) and cross feed (0.02 mm), allowing fine control of each grinding pass. Without complex programming or computer control, the RT-450 enables hands-on manipulation for custom job requirements and semi-automatic grinding tasks.

Robust Structure and Efficient Safety Features

Constructed of heavy-duty cast iron and enclosed in a wooden crate for shipping, the Alpa RT-450 ensures minimal vibration and optimal durability in demanding environments. Integrated coolant and centralized lubrication systems help preserve the machine and workpiece, while its floor space-efficient footprint (1600 x 1100 mm) allows for seamless integration into manufacturing facilities.

FAQ's of Alpa RT-450 Precision Surface Grinder Machine:

Q: How does the Alpa RT-450 Precision Surface Grinder achieve such high grinding accuracy?

A: The RT-450 is engineered for precision with a robust cast iron body, V & flat table slideways for stable movement, and fine graduation adjustments on the vertical (0.005 mm) and cross feeds (0.02 mm), ensuring grinding accuracy up to 0.003 mm. Its high-speed spindle and stable operation contribute to reliable surface finish quality.

Q: What is the process for operating this surface grinder, and is special training required?

A: Operation is primarily manual or semi-automatic, with both hand and power options for table feed. Operators set up the workpiece on the 200 x 450 mm magnetic chuck, adjust grinding parameters, and monitor the process. While basic machine knowledge is recommended, special CNC training is not required, making it accessible for users familiar with manual grinders.

Q: Where can this machine be installed and what are the space requirements?

A: The Alpa RT-450 is suitable for installation in industrial workshops, manufacturing plants, or tool rooms. With dimensions of 1600 x 1100 x 1700 mm, it occupies a modest floor space and can be integrated into both new and existing machine layouts.

Q: What materials can be processed using the RT-450 surface grinder?

A: Its 1.1 kW motor, 2800 rpm spindle using a 200 x 13 x 31.75 mm grinding wheel, and stable construction make this machine capable of grinding various metals and alloys, particularly suited for precision component finishing in industrial settings.

Q: When should the centralized lubrication system be used, and what are its benefits?

A: The centralized manual lubrication system should be operated regularly, as advised in the user manual, to reduce wear and maintain optimal performance. Proper lubrication extends machine life, assures smoother operation, and helps maintain high-precision grinding results.

Q: How does the coolant system enhance the grinding process?

A: The built-in coolant system helps dissipate heat during grinding, preventing thermal distortion of the workpiece and prolonging the life of the grinding wheel. This results in a consistent surface finish and maintains the dimensional accuracy of the workpiece.

Q: What are the main benefits of choosing the RT-450 for industrial applications?

A: Key benefits include exceptional grinding precision, durable cast iron build, ease of manual or semi-automatic operation, efficient lubrication and cooling systems, and flexibility for diverse industrial grinding applications without the need for CNC operation or complicated programming.
