Description:

The GT-H18MM Ball Hone Engine, featuring 180 grit, is a high-performance tool meticulously designed for precision honing. With a diameter of 18mm, this tool ensures versatility and efficiency in achieving optimal surface finishes for engine cylinders.

Key Features:

• Secure Holding: The Flex-Hone tool is engineered for secure placement in a collet, chuck, or similar holding device, providing stability during the honing process.
• Shortest Shank: Optimize stability and control by using the shortest shank possible for your application, ensuring precise and controlled honing.
• Lubrication and Rotation: Ensure thorough coating with lubricant and initiate rotation before entry, maintaining rotation until fully removed. This guarantees an effective and efficient honing process.
• Variable RPM: Operate the tool within a flexible RPM range of 60 to 1200, adjusting based on the tool diameter. Smaller diameters require higher spindle speeds. Begin with a spindle speed between 500-800 RPM, avoiding exceeding 1200 RPM.
• Cutting Oil or Honing Fluid: Employ a consistently high-quality cutting oil or honing fluid to minimize heat, prevent tool loading, and suspend removed material throughout the honing process.
• Continuous Stroke Rate: Maintain a continuous stroke rate ranging from 120 to 180 inches per minute for consistent and desirable honing results.
• Final Stroking for Crosshatch Finish: Accelerate final stroking to achieve a 45° crosshatch finish, enhancing overall surface quality.
• Efficient Honing Time: Utilize the minimum honing time necessary, typically 10-25 seconds or 5-15 strokes, to achieve the desired finish.

Technical Information:

• Tool Diameter and RPM: The tool's RPM range is diameter-dependent, with smaller diameters requiring higher spindle speeds. Experimentation may be necessary to find the optimum speed for specific applications.
• Heat Management: Consistently use cutting oil or honing fluid to manage heat effectively, prevent tool loading, and suspend removed material during the honing process.
• Stroke Rate: Maintain a continuous stroke rate between 120 to 180 inches per minute for effective and consistent honing.
• Crosshatch Finish: Final stroking can be accelerated to develop a 45° crosshatch finish, contributing to superior surface quality.
• Cleaning Procedure: Post-honing, clean the cylinder with hot, soapy water and a cleaning brush. Follow up with drying and additional cleaning using a lint-free cloth coated with a light oil or mineral spirits until the cloth remains clean.
