This page discusses the position of Pathak Industries (formerly known as Pathak Machine Tools) and the worksites its honing machines are best suited for. If you're interested in reducing the amount of inconsistency in interior diameter finishing by using reasonably priced equipment, this page presents key points you can use to see if its machines are the right fit for your applications.
Pathak Industries' honing machines are vertical machines in which the spindle is arranged perpendicular to the ground. They are used to mechanize interior diameter processing, making it easy to establish processing conditions that are more consistent than those produced by hand processing.
These machines are notable for their standard bore honing structure and the simplicity of their operation. They have what it takes to achieve a fixed level of processing quality and a higher level of reproducibility, without requiring operators to have any special skills.
These honing machines reduce reliance on manual work and variations in hole diameter finishing, which cuts down on the frequency of reworking and reprocessing. They improve finishing reproducibility, reducing differences in work quality from operator to operator, and they make it easier to assign processing work to new staff members.
With these machines, you can improve the efficiency of your operations, even when working with a small crew, and create a workplace capable of handling repair jobs with short turnaround times and small lot refurbishment jobs.
When you choose equipment, it's vital that you clearly identify the size and drive type you need and the types of workpieces you will use it on. The Pathak Industries PVH-200 is positioned as a vertical bore honing machine.
It is well-suited for internal diameter finishing and corrective finishing for small- and medium-diameter workpieces such as cylinders, bushings, and sleeves. It is a good fit for refurbishing and repair work.
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.
Below, we present the PVH-200, a typical model in Pathak Industries' lineup of vertical honing machines.

| Processing Range | Diameter: Max. ⌀200 mm Length: Not indicated on website |

The PVH-200 accommodates honing diameters of up to 200 mm, and is highly suited for post-boring finishing for engine cylinders and component refurbishing. It is an easy-to-handle vertical general-purpose machine that is an especially good choice for small factories and rebuilders that want to move away from manual polishing work.
The company's website does not present any usage case examples.
Pathak Industries' website states that it handles installation for orders in India free of charge. An installation team goes on site, installs the machine, and then explains and demonstrates how to use it. This makes it easy to start using these machines immediately after installing them.
In addition to providing maintenance services and accessories, Pathak Industries also overhauls its own machines. We have not been able to confirm warranty lengths or periodic maintenance agreement terms, so please confirm the scopes of warranties and agreements in advance.

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.
