RODA NyWheels Case Study: Precision Deburring & Surface Finishing for CNC Machined Parts

The Customer:
Precision Engineering with Demanding Finishing Requirements

Progressive Technology are specialist sub-contract engineers producing complex, high-value precision components. Their work includes advanced CNC multi-axis machining, carbon components, patterns, structural foams and additive manufacturing.

For this type of work, finishing is not simply cosmetic. Components often require sharp edges to be removed, machining marks to be refined and surface finishes to remain controlled and professional. The finishing process must be effective without damaging the geometry of the part or compromising the customer’s required specification.

The Finishing Challenge

In precision engineering, deburring and surface finishing often have to be carried out on detailed components with tight tolerances, complex shapes and varied materials. The finishing tool needs to be abrasive enough to remove burrs and refine edges, but controlled enough to avoid changing the underlying form of the component.

This is where mounted abrasive nylon tools such as RODA NyWheels are particularly useful. Their flexible non-woven abrasive construction allows the wheel to conform to the workpiece, follow edges and profiles, and produce a consistent finish without the aggressive cutting action of a rigid abrasive wheel.

Why RODA NyWheels were Chosen

Progressive Technology have used RODA NyWheels from Moleroda for many years as part of their finishing process. The wheels are used to remove sharp edges quickly, smooth machined areas and support consistent finishing across a variety of jobs.

“When we want to remove sharp edges quickly, without affecting the surface finish, RODA NyWheels are the best tool for the job. We use them on a 3mm spindle and use a variety of grades, dependent on the job we are doing.”

This is a key strength of the RODA NyWheel range. Different abrasive nylon grades allow the user to move from fine cleaning and light finishing through to heavier deburring and graining, depending on the material, component shape and finish required.

RODA NyWheels are designed for controlled surface preparation. Rather than behaving like a rigid grinding point, the non-woven abrasive nylon structure works more like a flexible three-dimensional web. It follows curves, holes, edges and profiles, making it suitable for detailed finishing work where consistency and control matter.

For Progressive Technology, this control is important because their components are produced to high standards and often serve demanding sectors such as motorsport, aerospace and defence. The finishing tool must help remove burrs and refine the surface without creating avoidable rework or damaging the part.

For this type of finishing, the 3mm shank format is a practical choice. It provides a secure, compact mounted abrasive tool that can be used in suitable rotary tools, micromotors, air tools and production setups. It is small enough for controlled detail work while still offering a strong, practical spindle size for engineering applications.

The 3mm RODA NyWheel range is available in multiple diameters and abrasive grades, allowing users to choose the most appropriate wheel size and cutting action for the part they are finishing.

Smaller 2.35mm shank options are available, these are more popular in jewellery and fine detail applications where greater access to tighter areas and extra precision are necessary.

Choosing the Right Abrasive Nylon Grade

RODA NyWheels are available in a wide range of abrasive nylon grades. Fine grades are typically used for light cleaning, delicate finishing and pre-polishing, while medium grades are useful for general satin finishing, line blending and everyday surface preparation. Coarser grades are better suited to heavier burrs, more visible machine marks, graining and aggressive cleaning.

Because the same RODA abrasive nylon grade system is used across several product formats, we recommend using the dedicated grade guide as the central reference when choosing colours and grades.

The Result:
Repeatable Finishing For Precision Components

By using RODA NyWheels, Progressive Technology are able to carry out controlled deburring and surface finishing as part of their wider production process. The wheels help smooth edges, refine surfaces and provide a professional finish while giving the user a high level of control.

For Moleroda, this case study highlights exactly why RODA NyWheels remain one of our most popular UK-made abrasive nylon products. They are compact, versatile, easy to use and available in a wide range of grades for different levels of cutting, cleaning and finishing.
