High Precision Helix Diamond Single Stroke Honing Tools
Adjustable Expansion Honing Sleeves, High quality of Diamond Abrasives 

Diamond Grit : D1(70#), D3(100#), D5(220#), D7(320#), D8(400#), D0(600#), D00(1200#)

BOSON Abrasvies supply CBN / diamond plated single pass honing tools and abrasive sleeves designed for your specific application. Single pass honing tools also known as single stroke honing incorporate an expandable, diamond sleeve mounted on a tapered mandrel for precision bore sizing and finishing.

Plated diamond tool shows high accuracy and extra long tool life. Diamond abrasives allow for consistency of size, surface finish and bore geometry.
Our technical specialist will work with you to determine the best solutions for your needs. Whether you need a single pass or conventional honing tools, we have the expertise and product range to creat the right solution for you.


Single pass honing is a high productivity bore finishing process, that imparts high precision form, tight tolerance control and high surface finish consistenly and precisely. The process involves passing a series of tools with pre-set sizes, progressively through the bore, in a single in-and-out stroke. Either honing tools or part, or both can be floating.

The number of tools that are used, depend on part material hardness, total stock removal amount, geometrical tolerances and surface finish requirements. Single pass honing tools are suitable for high production rates, ensuring very close bore size & geometric repeatability over a large batch size of order of tens of thousands of parts, reaching as high as 600,000 parts in one setting.

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.

Features:
Superior diamond plating process ensures long tool life, low cost per part.
Improved abrasive sleeve design for chip quick removal.
Greater accuracy and increased production efficiencies.
Custom design to meet your specific requirement.
Capable of adapting to most honing machines.

Diameter range: 3.50 to 70.00 mm.
