Description:

The GT-H20MM Ball Hone Engine with 180 Grit is a versatile tool designed for precision honing applications. It ensures optimal performance when securely held in a collet, chuck, or similar holding device. The tool is coated with lubricant before use, rotates throughout the honing process, and is suitable for spindle speeds ranging from 60 to 1200 RPM. With a focus on efficiency, this tool delivers a superior finish to engine components.

Key Features:

• Secure Holding Mechanism: The Flex-Hone tool is best utilized when securely held in a collet, chuck, or similar device, providing stability during the honing process.
• Optimal Coating and Rotation: Prior to entry, the tool should be well coated with lubricant and rotated continuously until fully removed from the part, ensuring consistent and effective honing.
• Variable Spindle Speeds: The tool accommodates spindle speeds ranging from 60 to 1200 RPM, with the recommended starting range between 500-800 RPM. Experimentation may be necessary to find the ideal speed for specific applications.
• Heat Management with Cutting Oil: Always use a high-quality cutting oil or honing fluid to minimize heat, prevent tool loading, and suspend removed materials during the honing process.
• Continuous Stroke Rate: Maintain a continuous stroke rate between 120 to 180 inches per minute for optimal results, and accelerate the final stroking if aiming for a 45° crosshatch finish.

Technical Information:

• Tool Diameter and RPM Relationship: Adjust spindle speeds based on tool diameter; smaller diameters require higher spindle speeds for efficient honing.
• Maximum RPM Limitation: Ensure not to exceed 1200 RPM during operation to prevent potential damage to the Flex-Hone tool.
• Honing Time Guidelines: Use the minimum honing time necessary to achieve the desired finish, with an average honing time ranging between 10-25 seconds or 5-15 strokes.
• Cylinder Cleaning Procedure: After honing, clean the cylinder using hot, soapy water and a cleaning brush. Dry the cylinder and further clean with a lint-free cloth coated with light oil or mineral spirits until the cloth remains clean.
