The roller burnishing tool "Superoll" is one of Sugino Machine's signature products. It has been adopted by many manufacturing sites in Thailand as a mirror finishing tool to improve surface roughness. Did you know that Superoll can also be used for mirror finishing of the side and bottom of grooves for attaching O-rings and sealing rings? This article introduces the features and specific applications of Superoll for groove finishing.

Machining technology for a new era: The unknown potential of Superoll

■ Expanding applications of grooving for O-ring
The machining of O-ring grooves (mirror finishing), which was difficult in the past, can be easily realized, and the functionality of the product can be expected to be improved.

■ Improved blade life
The use of Superoll enables efficient machining of narrow grooves, which is difficult with ordinary blades, and improves the blade life.

■ Stable machining quality
The use of Superoll ensures consistent quality without depending on the technical skills of the operator, thereby improving productivity and maintaining quality at the same time.

1) Superoll SR3Z for groove side surface (outer surface)

■ Features
・Both sides of the groove can be machined with a single tool
・Stable finish due to adjustable machining load
・Applicable to a wide range of materials from steel to non-ferrous metals
・Roller corner R0.2 minimizes the unmachined area
・Achieves Rz of 0.8μm or less, which is difficult to achieve with cutting

▲ installing

■ Specifications
・Workpiece shape that can be machined: Groove side surface (outer surface)
・Installable drive machines: General-purpose lathes, turret type lathes
・Machining range (mm):
Standard (groove width 3.6 or more / groove depth 5.5 or less)
Non-standard (groove width 2.2 or more / groove depth *Support on request)

2) Superoll SR24MW for groove bottom surface (outer surface)

■ Features
・Compact body allows installing on automatic lathes
・Enables groove finishing effective in improving O-ring life
・Improved “sealing performance” and “life” of O-rings

■ Specifications
・Workpiece shape that can be machined: Groove bottom surface (outer surface)
・Installable drive machines: General-purpose lathes, turret type lathes
・Machining range: Groove width 1.4 mm or more / Groove depth 5 mm or less
・Machining data: Surface roughness (μm); vertical magnification×2,000; horizontal magnification×50

▲ Machining Data
* The degree of finishing roughness can be adjusted by the pressurization of the spring built into the tool.
The degree of finished surface roughness can be adjusted so as not to increase the frictional resistance of sliding parts without crushing the surface roughness.

■ Main users and target sectors
・Shaft machining
・Electric motors
・Automotive parts
Widely implemented at various parts machining sites, and there is a growing demand in the industrial sector.

Test machining available before installation! Full range of maintenance services

We offer test rental services for customers who are considering implementing the system, allowing them to confirm the effectiveness with actual workpieces before installation. Additionally, while roller parts are consumables, proper maintenance will help maintain high-quality finishing. With technical support, you can try out the finishing process.

The roller burnishing tool "Superoll" is a tool that can achieve mirror-finish machining, diameter correction in micron level, strength enhancement, and surface hardness improvement in a single pass.

Since it can be used for mirror finishing of any machined shapes, it is widely used in various industrial sectors, and is expected to improve product quality and productivity.

With our service bases in Thailand, you can rely on us for everything from testing to post-purchase maintenance and after-sales support.
