Barnes Bore Honing & Finishing Systems is a manufacturer of bore honing machines primarily focused on interior diameter finishing. This page discusses the differences between its models, the strengths of each, and its support system.
The HV-1000 has a PC-based touch screen HMI, servo motor and ball screw-based stroke control, and an in-process component gauging function. The HH series offers not only programmable control but also tight spot detection through torque monitoring and a range of options through its tool extension design.
Both series use open design, so they are easy to maintain and easy to connect to automation equipment.
The programmable control and gauging functions facilitate the recording and reproduction of processing conditions, which helps reduce reliance on individual operators in set-up and adjustment. Torque monitoring and gauging make it easy to identify inconsistency during process and detect signs of abnormalities. The open designs of the models also reduce the workload involved in maintenance operations.
The information available from Barnes mainly concerns bore honing and bore finishing, and is primarily focused on interior diameter finishing.
The HV-1000 is a vertical spindle machine suited for components with small to medium-sized interior diameters, while the HH-25 is a horizontal machine for use with long tubes and cylinders. The model that's best for you will depend on the lengths and diameters of your workpieces, so checking the applications of each model will help in model selection.
Device capabilities and manufacturer support requirements vary from business to business, differing for precision components, large components and heavy industry, and component repair and processing.
We have carefully selected the honing machines that are best suited to companies based on the features and challenges of their varied businesses, freeing them from needing to rely on specific operators. Please use the information on this site in your comparisons and deliberations.

BS-VI standards and growing EV demand are driving unprecedented needs for precision machining.
While the "overseas components + local assembly" model keeps initial costs low, design mismatches and unclear accountability create long-term risks.
Integrated management from design to assembly ensures consistent machining accuracy regardless of operator, minimizing material loss, accelerating ROI, and building the foundation for global trust.

This honing machine synchronizes stroke and stone expansion in 0.1 μm increments, enabling precision honing of holes as small as 3 mm in diameter and 80 mm deep, even in hard materials.
Automatic electronic control and made-to-order jigs reproduce the techniques of veteran operators.
These honing machines eliminate deviations in the manufacturing of precision components such as control valves while also reducing personnel costs.

Machine height can be reduced through pit installation, reducing the footprint and using less volumetric space. It also makes it easy to mount and unmounts heavy objects such as engine blocks, reducing the operation workload.
They can even cut the large machining allowances unique to heavy industry in short amounts of time.

A graph showing the status of the hole being honed is displayed on-screen, in real time. This makes it easy to visually understand where the workpiece is and how it is warped, accelerating repair decisions.
These systems can store up to 100 processing settings at any time. They can also be backed up via USB, so even for small-lot, high-mix jobs, you can instantly reproduce the same processing as in previous jobs. They also shorten set-up times.
