MPS Modular Tool System Overview

The MPS Modular Tool System is engineered for HT/HL/STH honing applications, providing modular hone heads, mandrels, adapters, and accessories to cover a broad range of bore diameters and honing lengths. It emphasizes flexibility and customization for diverse industrial honing needs.

1. Hone Head Assemblies and Diameter Ranges

• MPS-H85 Module: Covers 85 mm to 177 mm (3.4"–7.0") diameter range; includes yoke, cage, hone body, pinion adjustment, stone and guide adapters, and swaging tool. Double length versions available on request.
• MPS-H165 Module: Diameter range 165 mm to 216 mm (6.5"–8.5"), similar components as H85 with extended size capability.
• MPS-H200 Module: Diameter range 203 mm to 299 mm (8"–11.5"); includes stone and guide extension sets; master holder and adapter blocks ordered separately.
• JS9X Cage Assembly and Extensions: Extends MPS-H165 and H200 diameter range to 279.4 mm–381.0 mm (11"–15"). Requires specific cage and extension sets.
• NH6X Cage Assembly and Extensions: Further extends diameter range to 381.0 mm–889.0 mm (15"–35") with multiple size-specific cage and extension sets.

2. Adapter Sets and Drive Extensions

• Drive and feed extensions available from 150 mm (5.9") to 1750 mm (68.9"), supporting honing lengths up to 1981 mm (78"). Extensions can be linked for longer reach.
• Each extension includes two disassembly rings; additional rings can be ordered separately.
• Adapter sets exist for various hone head modules (H50, H70, H85, H165, H200) with replacement parts such as input yokes, output flanges, universal covers, trip dogs, pins, and disassembly rings.
• GNR Drive Shaft Adapters provide enhanced strength for heavy-duty applications (diameters ≥ 88.9 mm). Quick change-over adapters are available but not recommended for rough or heavy-duty use.

3. Stone and Guide Sets

• Stone sets compatible with multiple hone heads and extensions, including metal bond superabrasive stones (CBN and diamond).
• Abrasive types: Aluminum Oxide, Silicon Carbide, CBN, Diamond; grit sizes range from 70 to 1200.
• Heavy-duty bronze guide shoes are offered for diamond or CBN stones when standard guides wear prematurely.

4. Mandrels and Portahones

• Mandrels available with 2 to 5 stones, covering diameters 25.15 mm to 66.68 mm (0.990"–2.625").
• Portahones designed for diameters below MPS-H50 range or for longer stone lengths to bridge interruptions like ports or cross holes.
• MPS-1000-JU5X Mandrel Driver adapts to drive and feed extensions for interrupted or undercut bores, covering 66 mm to 144 mm (2-5/16"–6").

5. Ordering and Special Notes

• Double length hone heads and longer mandrels available on special request; contact customer service.
• Mandrel orders must specify open or blind hole application.
• Stone and guide master holder and adapter block sets must be ordered separately for certain diameters and extensions.
• Consult product bulletins or sales representatives for large diameter or special application hone heads.

Critical Parameters and Recommendations

• Match diameter ranges and honing lengths precisely with appropriate hone head modules, extensions, and mandrels.
• Use GNR Drive Shaft Adapters for heavy-duty or rough applications requiring stronger shafts.
• Order stones per H70 Stone Selection Guide or P28/R28 sections for mandrel driver applications.
• Ensure inclusion of all necessary components (yoke assemblies, cage assemblies, pinion adjustments, adapter blocks) for complete tooling setups.

The system offers scalable, precise honing solutions across a wide bore size range and application complexity, supporting both standard and custom tooling configurations.

Hole Honing Equipment Overview
