the Flexible Cylinder Hone Tool

 

For Any Type and Size of Cylinder...

Cylinder Honing a metallic product (Super Finishing) produces a controlled surface condition unobtainable by any other method. It involves finish, geometry and metallurgical structure. A high percentage plateau free of cut, torn and folded metal (with radiused ports).

A resilient, flexible, honing tool with a soft cutting action. The abrasive (points) globules each have independent suspension that assures the Flexible Cylinder Hone to be self-centering, self aligning to the bore and self-compensating for wear.

Specifically, it is a low-temperature abrading process that exposes the undisturbed base metal structure to produce a long wearing surface. It is a method of developing a surface on a metal part which is optically smooth and metallurgically free of any fragmented, amorphous or smeared metal from previous operations. It is accomplished at a low pressure where the “stones” float across the surface. The final achieved finish ensures a superior performance in situations dependant on the condition of the surface.

The unique crosshatch created by a Flexible Cylinder Hone is extremely efficient.  It provides a multiplicity of oil grooves or valleys for oil retention, as opposed to the often un-directional or uneven valleys common to the conventional type rigid hone. These crosshatch patterns remains longer than the rigid ones, as the cylinder wall is wear-reduced after hours of use.
 

Typical Applications Include:

• Air Compressors • Compressed Air Tool Bodies • Hydraulic Ram Cylinders • Brake Cylinders (Wheel)

• Hydraulic Valve Bodies & Valve Guides • Clutch and Brake Master Cylinders

• Hydraulic Motor Bodies • Finishing of Stainless Steel Tubing

• Pneumatic Cylinders • Brake Rotors

• Surface finishing of Boiler Components • Engine Cylinders and Block Liners

Although the FLEXIBLE CYLINDER HONE tools are manufactured in an extensive range of diameter sizes and grits for most applications, there will be times
a custom tool must be made to achieve the results required. Please consult us for pricing and delivery time on all special order, special application hones.

To assist in selection of proper hone, this information is a good starting point. Actual measurements
must be made after honing, as numbers will vary depending on the material being honed and the media used.

What size should I order?

A hone tool's diameter is determined by the nominal bore size in which the tool is to be operate. A cylinder hone is always produced and used in an oversize condition.  The degree of oversize creates pressure and a soft cutting action on cylinder walls.  For example a 1" Flexible Cylinder Hone tool is ordered if a 1" bore (I.D.) is to be finished, the built in oversize provides the proper cut.  Remember that all tools are provided in oversized, so do not add inches or mm's to the ID that you are machining.  If the bore size is between standard sizes, the next larger standard Flexible Cylinder Hone should be selected.

Important note:

If the Ra (surface finish) of the part being machined needs to change more than 20 to 30 points, you may need to use steps to achieve the proper final Ra. As an example, if you were trying to change a 80 Ra to a 20 Ra, you may need to start with a 120 or 180 grit hone and then finish with a 240 or 320 grit. This stepping concept reduces the chance of damaging the tool due to over heating, when too fine a grit is used for an extended run time to try and remove excessive roughness.
