Lathes Sanding Belt Holder

Description

Description of the MST-SBH External Lathe Sanding Belt Holder

The MST-SBH external lathe sanding belt holder is designed to provide safer, more precise, and more consistent finishing operations directly on rotating machined parts. Ideal for metal, alloy, and wood applications.

Mounted directly to the existing tool post of conventional or CNC lathes, the MST-SBH securely holds abrasive belts used for sanding, polishing, deburring, and finishing operations. Its design allows operators to work with excellent stability while maintaining consistent pressure on the workpiece. It eliminates the hazards associated with improvised tool holders, improving operator safety and finish consistency.

Unlike manual sanding methods where the operator holds abrasive paper or abrasive belts directly against a rotating workpiece, the MST-SBH keeps hands away from the working area while improving finish uniformity. This hands-free approach helps improve operator safety and reduce the risks associated with manual finishing operations on lathes. It also promotes more repeatable results and is better suited to industrial production and maintenance environments.

Designed for intensive industrial use, the MST-SBH is manufactured from durable, heavy-duty materials. Its three-position opening system allows it to quickly adapt to different workpiece diameters and a wide range of operating conditions.

Its ingenious design allows for:

The MST-SBH is available in 2 versions designed to meet different production requirements:

• Manual Mode (MST-SBH Model) for simple and efficient sanding operations
• Manual Mode with Belt Clutch Control (MST-SBH(A) Model) providing greater rotational control, ideal for applications where precision is critical. (Important: this tool is not motorized and cannot be motorized.)

Its innovative design provides:

• Easy adjustment to different workpiece diameters through three opening positions
• Direct installation on existing tool posts of conventional lathes
• Compatibility with a variety of materials, including metal, certain alloys, and some wood applications
• Simple integration into industrial production and maintenance environments

Compatible with both conventional and CNC lathes, the MST-SBH improves surface finish quality while reducing the risks associated with manual sanding during turning operations.

Each device includes 3 abrasive belts, allowing immediate start-up after installation.

The MST-SBH is designed in accordance with international standards applicable to machine tools and industrial turning operations, ensuring compliance with globally recognized industrial safety requirements.

Why Replace Manual Sanding on a Lathe?

In many machine shops, sanding, polishing, deburring, and finishing operations are still performed manually using abrasive paper or abrasive belts held directly against rotating workpieces during turning operations.

Although this method remains common, it can be difficult to control and may lead to significant variations in finish quality from one operator to another. Manually holding abrasives against a rotating machined part can also increase operator risk, contribute to physical fatigue, and reduce the repeatability of finishing operations.

The MST-SBH was designed to replace these manual methods with a safer, more stable, and more controlled solution better suited to industrial production and maintenance environments.

Thanks to its controlled abrasive belt support system, the MST-SBH provides:

• More uniform and consistent finishes
• Improved control of the applied pressure
• Reduced manual handling
• Greater process repeatability
• Improved safety during turning operations

What are the Advantages of Using the Prismont Lathes Sanding Belt Holder?

Improved Safety

The MST-SBH allows sanding, polishing, and finishing operations to be performed without manually holding abrasives against rotating workpieces. This hands-free approach helps reduce the risks associated with manual finishing operations on lathes.

Uniform and Precise Finishes

Thanks to the stable positioning of the abrasive belt and consistent control of the applied pressure, the MST-SBH helps produce more uniform and repeatable finishes on turned surfaces.

Increased Productivity

Using a dedicated sanding tool helps speed up finishing operations while reducing costs, manual adjustments, and variations between operators.

Reduced Operator Fatigue

The controlled support of the abrasive belt reduces the physical effort associated with manual sanding operations and improves operator comfort during extended periods of use.

Repeatability

The use of the MST-SBH can help achieve consistent and repeatable finishes on similar parts, making it particularly valuable for mass production environments where repeatability is critical.

Frequently Asked Questions About the Sanding Belt Holder for Lathes

What is the difference between the MST-SBH, MST-SBH(A), and MST-SBH(AIR-D)?

The MST-SBH operates manually and allows hands-free sanding and polishing operations to be performed directly on the lathe. It includes the MST-SBH1.0, MST-SBH2.0, MST-SBH4.0, and MST-SBH4.0EX models.

The MST-SBH(A) operates on the same principle but adds mechanical resistance for better control of belt rotation. It does not use a motor. It includes the MST-SBH(A)1.0 and MST-SBH(A)2.0 models.

The MST-SBH(AIR-D) is the motorized version of the range. Its pneumatic motor automatically drives the abrasive belt at a constant speed without requiring manual belt rotation.

Which Model Should I Choose Based on the Diameter of My Parts?

The choice of model depends primarily on the diameter of the workpieces and the available space around the workpiece on the lathe. The different MST-SBH and MST-SBH(A) sizes allow the tool to accommodate a range of workpiece diameters and operating conditions.

The compact models MST-SBH1.0 / MST-SBH(A)1.0 are suitable for diameters up to 150 mm (6″), the intermediate MST-SBH2.0 / MST-SBH(A)2.0 up to 200 mm (8″), the MST-SBH4.0 up to 300 mm (12″), and the MST-SBH4.0EX up to 500 mm (20″). The technical specifications table above serves as a useful reference.

On What Type of Lathes and for Which Materials Can I Use This Tool?

The lathe sanding device is suitable for both conventional and CNC lathes. It can be used on metal, alloy, or wood parts during turning operations.

I regularly perform sanding or polishing operations. Would a motorized version be more suitable?

For repetitive operations, the MST-SBH(AIR-D) provides a motorized alternative to the MST-SBH and MST-SBH(A). Its pneumatic motor drives the abrasive belt at a constant speed and reduces the amount of manual handling required during finishing operations.

The choice between manual and motorized models depends on factors such as the type of operation, how frequently it is performed, and the desired level of automation.

Can I use the same abrasive belts with the MST-SBH(AIR-D)?

Yes. The MST-SBH, MST-SBH(A), and MST-SBH(AIR-D) use the same abrasive belt and felt belt sizes when the tool dimensions correspond.

Important : Abrasive belts must match the tool size. Belts designed for a 4.0 model must not be used on a 1.0 or 2.0 model, and vice versa.

What other sanding and polishing tools for lathes does PRISMONT offer, and how do I choose the right tool for my application?

The PRISMONT range includes several solutions designed for sanding, polishing, and finishing operations directly on machined parts, including manual tools, motorized tools, and tools designed for internal polishing.

Choosing the right tool depends on factors such as the type of operation to be performed, workpiece dimensions, frequency of use, and the desired operating mode.
