Revenue model

1. Honing Tools and Tool Systems: Manufacture and sale of precision honing tools (multi-stone, single-stone, shell, fixed diameter, custom) and modular tool systems (coolEX, coolEXact, coolEXfloat, Xstep, FDhone) for machining centres and dedicated honing machines. Tools are produced for machine systems including Nagel, Kadia, Gehring, Sunnen, Delapena, Nissin, Fuji and Pleiger.
2. Tool Rental: Rental of honing tools from stock including single-stone, multi-stone, shell, fixed diameter and double expansion tools. Includes replacement ledges, shells and adapters. Tools available in diameters from 4mm to over 200mm.
3. Subcontracting / Job Honing: Contract manufacturing including CNC honing on vertical machining centres, turn/mill centres, CNC turning and milling, CNC spark erosion, CNC wire cutting, conventional honing, surface grinding, cylindrical grinding, deep hole drilling and automatic welding. Primarily for small series and prototypes.
4. Tool Repair and Overhaul: Inspection, repair, economic refurbishment of honing tools including wear part replacement and component completion. Also refurbishes worn measuring devices ( carbide pad fitting, recoating) and manufactures fixture parts to sample or drawings.
5. Training and Consultation: Technical training on honing technology, tool types, expansion systems, coolants, abrasives, and process design. Consulting on tool selection, process design, honing on machining centres, coolant selection, and independent machine type selection advice.
6. Process Layout / Application Engineering: Six-step application engineering process from task information through analysis, test execution, test analysis, optimization, to production release and after-sales support. Includes trial tooling planning and on-site accompaniment.
