Description:

The 1pc Cylinder Honing Tool, specifically designed for 76mm (3") engine cylinders with a 180 GRIT and a ball-type construction, is engineered for precision honing applications. Covering a diameter range of 72-76mm, this tool ensures optimal performance when securely held in a collet, chuck, or a similar holding device.

Key Features:

• Secure Holding Mechanism: Ensure precise honing by securely positioning the Flex-Hone tool in a collet, chuck, or a similar holding device.
• Optimal Shank Length: Enhance control and precision by using the shortest shank suitable for your application.
• Lubrication and Continuous Rotation: Ensure a smooth honing process by coating the tool with lubricant, initiating rotation before entry, and maintaining it until fully withdrawn.
• Variable RPM Range: Adapt the tool to different spindle speeds, ranging from 60 to 1200 RPM. Smaller diameters require higher spindle speeds, with a recommended starting range of 500-800 RPM.
• Cutting Oil Requirement: Manage heat effectively, prevent tool loading, and suspend removed materials by consistently using good quality cutting oil or honing fluid.
• Continuous Stroke Rate: Maintain a continuous stroke rate between 120 to 180 inches per minute for optimal honing. Accelerate final stroking if a 45° crosshatch finish is desired.

Technical Information:

• Diameter and RPM Relationship: Adjust spindle speeds based on the tool diameter, with smaller diameters requiring higher spindle speeds for efficient honing.
• Speed Experimentation: Users may need to experiment to find the optimum spindle speed for their specific application, with the recommended starting range provided.
• Maximum RPM Limitation: Avoid exceeding 1200 RPM during operation to prevent potential damage to the Flex-Hone tool.
• Heat Management and Material Suspension: Consistently use a high-quality cutting oil or honing fluid to manage heat, prevent tool loading, and suspend the material being removed.
• Honing Time Guidelines: Utilize the minimum honing time necessary to achieve the required finish, with an average honing time ranging between 10-25 seconds or 5-15 strokes.
• Cylinder Cleaning Procedure: Post-honing, clean the cylinder using hot, soapy water and a cleaning brush. Dry the cylinder and continue to clean with a lint-free cloth coated with light oil or mineral spirits until the cloth remains clean.
