The Valve Guide Knurling consists of a reamer, knurling arbor, brush, speed reducer, and tap wrench. It works by first using the reamer to carefully enlarge and smooth the inner diameter of the valve guide. The knurling arbor is then inserted into the guide, and the speed reducer is used to control the rotation speed. As the arbor turns, the knurled surface creates a serrated texture on the inner walls of the valve guide.Attributes:• Minimize oil leakage and blow-by, resulting in lower emissions and improved environmental compliance• Provides better heat transfer from the valve to the guide, helping to dissipate heat more efficiently and reducing the risk of valve failureApplications:The Valve Guide Knurling creates the tool unit and enhances the contact area between the valve and the guide, resulting in a tighter seal and reduced oil consumption.
