Sanding tools

Bore honing is the finishing process that improves surface quality and the precision of the manufactured component, performed with horizontal or vertical axis honing machines.

The machining process involves the use of honing tools that, through the rotation of the spindle and the reciprocating movement of the workpiece carriage, by expanding the abrasive parts according to set parameters, remove the required stock, ensuring highly accurate finishes and high precision.

MOMA develops a honing technology high-end for small, medium, and large bore diameters. Robustness, reliability e precision are the foundation of the work established and developed by MOMA.
Our projects start from a deep knowledge of finishing applications, from development carried out with 3D CAD systems and cutting-edge machine tools, which allow us to guarantee realistic delivery times, even for special applications, achieving tolerances on geometries and surfaces typical of the hydraulics world.

Our tooling range includes standard and special solutions for complex honing applications for almost all bore diameters.

Main highlights:

Ideal in the diameter range from 4mm to 40mm (Standard) up to very large dimensions
Two-piece design for easy replacement, cleaning, and maintenance of parts\r\nShort delivery times
Front indicator light highlighting the stone wear limit, allowing even less experienced operators to manage the production cycle
Absence of contact parts between the spindle body and the workpiece, thus ensuring constant roughness values and a very long life for our tools
Possibility of using both conventional abrasives and super-abrasives
Executions specifically designed and manufactured for machining blind holes, tandem holes, interrupted holes, etc.

The development and design of honing stones is carried out thanks to an analysis conducted at the customer’s site and the experience of many successfully implemented honing processes.

The MOMA product range includes:

Resin-bonded, ceramic, metal-bonded, and electroplated honing stones and honers, available in both single-use and reconditionable versions
Conventional abrasives and superabrasives
Reduced machining times
Production process efficient in terms of repeatability

Process development and consulting
Prototype honing tools
Honing
Trial samples of available material
Small demonstration batches
Repair of honing stone holders
Replacement of expansion rods
Restoration of damaged parts
Honing oils, both mineral and synthetic-based, with excellent cleaning, lubricating, and cooling properties, essential in superfinishing processes

This honing technology is indispensable wherever it is necessary to improve the functional sliding properties, guidance or sealing properties between contacting surfaces in bores.

Typical applications include: injection systems, vehicle transmissions, turbochargers, hydraulic components, ceramic parts, small engine blocks, connecting rods, pistons, lubrication systems, medical and glass applications, and finally military and aerospace industry components.
