delapena is a dedicated honing company that doesn't just manufacture machines, but also makes tools and honing stones and provides maintenance services. This article looks at its bore honing machines and provides information you can use to decide if its machines are a good fit for your applications.
iHone, is a proprietary dialogue-based control system, operated via a touch panel, that assists with set-up and processing condition reproduction. ProductionHone models offer in-processing gauging that continuously measures hole diameters in real time while processing is in progress. It has an automatic tool changer for switching between multiple tools, and a high-precision XY table that closely controls the positions of workpieces.
delapena handles everything in-house, from machines to tools, honing stones, and process condition development. Because of this, its machines excel at set-up and processing condition reproduction.
By integrating measurement functions and saving processing as programs, these honing machines produce consistent processing condition calculation results and consistent and uniform operation. Saving processing as programs also reduces the workload involved in set-up and switching workpiece types.
delapena provides comprehensive support that covers everything from tool and honing stone selection to processing condition development, so it identifies and specifies conditions after equipment deployment, helping reduce the risk of startup delays.
The ProductionHone integrates honing and gauging. It is well-suited to precision boring automation and mass production. The PowerHone E is a vertical, electrically-controlled device that is suited for large diameter, heavy workpiece bore processing with diameters of 25.4 to 740 mm and a maximum reciprocating stroke of 1,000 mm. Its design supports both through hole and blind hole processing for large components.
Before choosing one of these models, check whether your needs primarily lie in precision automation or working with large diameter, heavy workpieces.
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.

The PowerHone E is a vertical model capable of both through hole and blind hole processing. It is suited for large and heavy components. It has an electric actuator, and rotation speeds of up to 250 rpm and reciprocating speeds of up to 30 m/min can be saved in programs and called as needed. This ensures the reproducibility of processing conditions.

delapena recommends its machines be inspected periodically, once per year, and it sends its service engineers out to customer sites to perform these inspections. During the inspections, the service engineers check for wear to the drive assembly, pipes and fittings, and stroke and carriage assembly. delapena's support doesn't end when its machines are installed. It also focuses on keeping its machines running, and it's easy to approach for consultation.
delapena offers on-premise training at customer worksites and shows operators how to configure machines based on the actual components they will process. It handles tool refurbishment and customer-exclusive honing stone inventory management, even for other companies' products, and develops processing applications. One of its advantages is that it makes it possible to consolidate all maintenance in a single company, even when installing equipment overseas.

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.
