NISSIN ProSOL is a Japanese honing machine manufacturer. It applies Japanese quality standards to all of its operations, so it offers one of the great benefits of a Japanese manufacturer: making it easier to secure the approval of parent companies and developers. This page presents the strengths of its product, its product lineup, deployment case examples, and its support structure in India.

The strengths of NISSIN ProSOL's honing machines

Stable Precision, Even in Hard Materials

The heart of a honing machine is its honing stone, and NISSIN ProSOL's G Series of honing machines use servo-controlled mechanical expansion mechanisms for handling honing stone expansion. The amount of honing stone expansion is closely controlled in line with the spindle stroke, making it easy to perform stable minute cutting.

These machines maintain stable circularity and surface roughness even when performing extremely small-diameter honing and when processing hard materials such as hardened steel or stainless steel. They produce the precise interior finishing required of precision components such as hydraulic valves, and their designs make it easy to reproduce process quality even during mass production.

How NISSIN ProSOL's honing machines can transform your operations

NISSIN ProSOL's honing machines are automatically controlled using CNC, so anyone, regardless of their skill level, can reproduce the techniques of experienced operators. They also reduce the amount of effort needed for manual dimensional adjustment and equipment operation stoppage by operators. They improve both quality and production performance, increasing operation rates for production lines as a whole.

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.

Applications of NISSIN ProSOL's honing machines

As a rule, these honing machines are driven by servo motors, and they are available in a wide range of sizes, such as small and medium-diameter models with processing diameters of ⌀3 to 100 mm and long workpiece models which can handle depths of up to 350 mm. They are widely used by automobile and motorcycle manufacturers that require high precision (for connecting rods, cylinders, and the like) and in mass production lines for hydraulic and pneumatic devices, industrial machinery, and more.

Standard honing machine suited for high-speed mass production of small diameter components

This model is well-suited for worksites that require steady mass production of relatively small diameter (⌀3 to ⌀40 mm) components, such as gears or valves. With these machines, it's easy to make consistent minute cuts necessary for small diameter workpieces. Other features are that they help shorten cycle times while achieving high processing quality. These standard machines are easy to deploy in production lines, especially lines for small-diameter components.

A model that supports a wide range of diameters, helping make mass production lines more versatile

This model is well-suited for plants that mass-produce small and medium-diameter components with different sizes, such as pinion gears and automobile connecting rods. One of its features is that it supports diameters from ⌀4 to ⌀100 mm, so it covers a wide range of workpieces that can't be accommodated by the G25. These models are a good choice for worksites which deal with multiple mass production components, as they offer a balance of versatility and productivity.

A model that combines rough finishing, final finishing, and automated measurement in a single machine

This model specializes in processing medium-sized workpieces (⌀50 to ⌀80 mm), such as motorcycle cylinder blocks and truck components. What sets it apart from the G25 and the G50 is that it handles rough finishing, final finishing, and automated measurement, all in one machine. It eliminates the need to use multiple different machines, so it helps save factory floor space while shortening cycle times and improving productivity.

NISSIN ProSOL honing machine usage case examples

Achieving a hole diameter tolerance of 5 µm and reducing product defect rates

  • Installed product: G50-MS2
  • User: Transportation equipment manufacturer

Background

In this case example, the G50-MS2 was installed by a manufacturer of key safety components used in transportation equipment. Due to its age, its existing honing machine had become unable to maintain a consistent level of processing precision, so the company struggled with numerous defects and an overall decline in the efficiency of the production line. It needed to meet the demanding requirement of a hole diameter tolerance of 5 µm, so it was vital that the company replaced its machine with one which could reduce the amount of deviation from the rough processing stage and which could perform consistent measurement and correction.

Benefits of deployment

The company deployed a G50-MS2 Honing Machine with an RG Sizing Mechanism due to the machine's sizing approach, which eliminates measurement inconsistency by using a gauge instead of air, and the reliability offered by the company's long-term support system. The new machine's measurements are highly accurate, and the manufacturer has consistently achieved its target hole diameter tolerance of 5 µm or less. In addition to defect rates falling, the honing machine also almost completely eliminated the need to stop equipment to make manual adjustments, improving the operation rate for the entire line.

Halving processing time and creating a mass production system for manufacturing 25,000 units per month

  • Installed product: G25-AR1 (fully automated one-spindle model with insertion and ejection loader)
  • User: Industrial machinery component manufacturer

Background

The industrial machinery component manufacturer faced a production capacity bottleneck: the electroplating method used for internal diameter finishing. To meet customer demands for increased production, it needed a fabrication method that would stabilize precision, shorten processing times, and maintain its processing capabilities even without the involvement of operators.

Benefits of deployment

Changing to honing for the interior diameter finishing made it possible to achieve consistent precision for the hole diameter, cylindricality, and surface roughness by automatically compensating for honing stone wear. The machine was installed after performing test processing, and it succeeded in halving the processing time to just 30 seconds per unit. It eliminated the need for operators to make dimensional adjustments, and the company is now within reach of its increased production goal of 25,000 units per month.

NISSIN ProSOL's maintenance system and after-sales support

A production system that handles every step in-house

NISSIN ProSOL designs and manufactures its machines, jigs, honing stones, and automation units entirely in-house. It performs integrated management, so it can help you create a speedy mass production system, without giving you the runaround. Another of NISSIN ProSOL's strengths is that it has a site in Gurugram, so it can go on-site in the event of a problem, talk with operators, and address any issues.

Pre-deployment test processing and processing condition proposals

NISSIN ProSOL can use prospective customers' components to perform test processing before deploying machines. This makes it possible to confirm processing times, straightness, hole diameter, and surface roughness precision. In addition to loaner units and piecework, the company's experienced staff can also propose jigs, tools, and processing conditions. In its support, it leverages the know-how it has accrued through its track record of delivering over 100 machines within India.

Top Three Honing Machines
That Free You from Reliance on Individual Operators

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.
