| PROHONE PRH - Progressive Honing System |
|
The progressive honing system, alternative to the expansion system, utilizes sintered diamond tools.
The system is capable of responding and adapting to customer requirements. It can handle a broad range of materials such as treated steel, ferrous metals, cast iron, carbon fibres, silicon metals
(in the absence of defoliating effect), lightweight alloys and ceramics.
The number of tools and diameter increments are determined in accordance with the metal stock removal.
The progressive honing system offers:
- High throughput
- Superb quality
- Excellent flexibility
- Rapid changeover times
- Minimum maintenance.
Tools
Comprising of a one piece steel unit which is easily and rapidly set up ready for immediate use, the tool can be easily adjusted to set diameter increments for different bores. The diameter increment adjustment is controlled by electro-pneumatic gauges for precision measurement of the bores obtained.
Each set of tools is capable of honing 800,000 to 1,000,000 cast iron bores. The one-piece sintered tool is ideal for honing bores of all types: through holes, blind holes, counter-bored and intersected holes.
Duty cycle
The cycle is completed in about half the time required by other machining system currently available. This is beacuse the vertical multi-spindle head completes the cycle in a single forward and return operation. The system's multiple programming capability also increases flexibility and significantly reduces retooling downtimes.
Process capability analysis
The progressive honing system guarantees production lots within a single tolerance range (tolerances to within one micron). Workpieces are automatically and individually controlled at the end of each honing cycle. The machine can be interfaced with an SPC system on request.
Roughness
The required degree of roughness is determind by several factors: type of diamond tool used, abrasive density/grit size and CNC-programmed operating parameters (i.e. feed rate and RPM).
