Fuji Honing is a Japanese manufacturer dedicated exclusively to honing machines. It has been working with polishing and processing technologies since 1949. This page presents its lineup of products, their strengths, and their applications.
Fuji Honing's MRX/MRNX series has a spindle shift function that moves the position of the honing stone to match the position of the hole and is controlled using CNC. It offers multiple options for the method used to press honing stones against workpieces, including mechanical and hydraulic methods. The FS series uses servo motors for rotation, reciprocal motion, and honing stone feed, so it can seamlessly adjust honing stone sizes. It shortens set-up times and produces more stable processing precision.
Fuji Honing's machines reduce inconsistencies in finish quality thanks to their servo control and automatic measurement feedback. One of their benefits is that they contribute to greater processing stability that is not dependent on the skills of individual operators. Some of Fuji Honing's machines have IoT-enabled preventative maintenance systems which monitor the status of individual drive components and coolant and help prevent unexpected shutdowns.
The MRX/MRNX series of machines are servo machines with multi-spindle, fully customizable designs that support diameters of ⌀25 to 150 mm. They are well-suited to use in large-scale production lines. The FS series of machines are compact devices specialized for small diameter honing, with diameters of ⌀1.8 to 50 mm.
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.

These honing machines have a compact design, with a footprint of just 1,000 x 1,500 mm, yet they come equipped with a spindle shift function. Even if different workpieces with different hole positions are used, processing can continue without needing to change the machine's position. This shortens set-up switching time, making it especially convenient for plants that handle a wide variety of products.

The FS series is a series of compact machines, measuring just 1,600 mm wide by 700 mm deep, for small diameter honing of holes with diameters of 1.8 to 50 mm. One of their features is their intuitive control screen, which is easy for all operators to use, even those unfamiliar with the devices. The automatic measurement feedback function performs measurement and correction automatically while processing is in progress, helping produce more stable quality.

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.
