Product Description

Single Pass Honing Tools, Sintered Diamond Abrasive Sleeves for High Precision Bore Honing


Honing improves and guarantees bore geometry accuracy and finish after operations such as machining, heat treating or chucking.

Corrects the following conditions:
Out-of round, Taper, Boring Marks, Chatter Bell Mouth, Undersize, Barrel Shapes, Rainbow, Misalignment, Waviness. Additionally, cuts all materials, ferrous and nonferrous


Progressive Honing

The progressive honing sequence is very simple and does not require the presence of any skilled operators, it consists of a number of vertical honing tools, combined with a horizontal table which index/rotates under the spindles.

Progressive Honing Sequence
Each honing tool is preset to a progressively larger diameter, and as the workpiece passes through the machine's cycle it has its diameter increased in size by each spindle in turn. Each honing tools passes through the bore one single time only. At each pass the tool removes a specific quantity of material and the bore diameter is progressively increased, calibrated and finally finished step by step.


According to the material, the stock removal, the surfance finish and the required geometry, the honing range can include 1 to more than 10 honing tools.



Electroplated Diamond Honing Tools
The electroplated abrasive sleeve is manufactured by depositing a layer of nickel or nickel alloy onto the surface of the substrate through an electroplating process, while embedding diamond or cubic boron nitride (CBN) abrasive particles uniformly into the plating layer. This process ensures that the abrasive particles are evenly distributed on the surface of the sleeve, thereby enhancing high cutting efficiency and precise dimensional control. The electroplated abrasive sleeve exhibits very high cutting capability during the initial stages of honing, making it particularly suitable for the high-precision machining of hard materials.

• Diameter Range: Ø3.5 mm - Ø80 mm

Key Advantages:
• Sharp cutting edges for aggressive material removal
• Ideal for initial honing stages and hard materials
• Short cycle time and high throughput
• Suitable for materials like hardened steel, cast iron, ceramic, powdered metal

Sintered Diamond Honing Tools

The metal sintered abrasive sleeve is manufactured by uniformly mixing superabrasives (such as diamond or cubic boron nitride), metal powder, and binders in specific proportions, then pressing them into shape and sintered at high temperatures. After sintering, the product undergoes multiple stages of precision machining. The abrasive particles are uniformly distributed throughout the sintered body, forming a structure with multiple layers of abrasives. As the surface abrasives wear, new abrasive particles are gradually exposed, ensuring the tool maintains stable cutting performance and a high surface finish during use.

• Diameter Range: Ø4 mm - Ø80 mm

Key Advantages:
• Long tool life and consistent performance
• High surface quality throughout tool usage
• Suitable for finishing operations and fine tolerances
• Recommended for precision components in continuous production


Single Pass Honing relative to Conventional Honing
Conventional honing is done by a tool that expands and contracts as the tool reciprocates in the bore during the honing cycle. Simultaneous radial and axial movements of the tool make it difficult to precisely and consistently control the bore size and geometry. Although conventional honing does offer excellent bore finishing, batch sizes and bore controllability are limited by the nature of the process.

Single pass honing tools with expandable abrasive sleeve coated with diamond or CBN grit. The tools hone the bore in one pass only, removing a certain specific amount of material per tool. With a set of tools working on the bore progressively, bore size & geometry are controlled precisely and consistently over a large batch size. Since the tool stroke is only once in single stroke honing ,cycle time is greatly reduced.

Single Pass Honing Tools
The single pass honing tools comprise
a, An expandable abrasive sleeve that have embedded diamond or CBN grits.
b, A tapered mandrel on which the abrasive sleeve is mounted and affixed.
The honing sleeve is set to size during the set-up, once set, further adjustment or movement is not necessary during the cutting cycle.
