Microfinish machine reduces EDM time
The development of the new Guyson Microfinishing system has been targeted at lowering manufacturing costs for the tool manufacturer using EDM.
The development of the new Guyson Microfinishing system has been targeted at lowering manufacturing costs for the tool manufacturer These include reducing the operating times of spark eroding machines during smoothing operations, quicker cleaning of white zones, reducing time spent on grinding and polishing operations, gaining easier access into the cavities within shaping areas such as corners, grooves, holes and hollows and reducing the surface profile

Keying surface produced for anodising
When Bodycote a world leader in metal technology, were faced with a demanding finishing problem, coupled with an extremely tight delivery deadline, they approached Guyson International for help.
To achieve these results, many changes in current beadblasting technology have been introduced.
These include the development of two formulations of speciality microfinishing cleaning and finishing media, a three gun installation, a roller turntable for positioning the tools and additional facilities for ensuring the efficient movement, handling and containment of ultrafine powders and dusts.
The first cleaning operation is directed at the removal of all traces of white and melting zone deposits from spark eroded areas.

Quality cleaning for metal worked components
Metal-worked aluminium components are literally singled out for individual treatment by a new, aqueous based, three stage, wash rinse and dry system from Guyson International.
The ultrafine granular nature of the new blast media assists penetration into shaped areas of poor access and removes surface defects such as grooves and scoremarks from ground and milled areas.
The result is a completely clean, slightly roughened surface with a low, angular surface profile ready for either coating or plating as required for the particular form tool.
The second stage uses a completely different blend of ultrafine beadblast media to round off the minute, slightly roughened peaks of the superfine profile and to compact, level and smooth the surface using a peening action to produce a sheen effect.
The result of the two-stage process is a low, rounded, microdimpled profile with a finish acceptable for immediate production use or final polishing.
The finest of the three is a pencil-shaped micronozzle with an internal diameter as small as 0.8mm and able to blast only ultrafine media of a particle size of less than 300 microns.
This allows accurate targeting of the blast spray and ensures that the process can be carried out exactly at the desired spot without the risk of provoking 'tensions' or excessive heating - especially in the case of hardened steel and alloys.
A series of metal rollers fitted within the cabinet floor allow easier forward, reverse and rotational movement of the heavy form tool during processing.
Consistency of finish and environmentally safe workshop conditions are maintained by uprating the airwash, media recycling and dust filtration Facilities to handle and contain the additional volumes of ultrafine media and dust within the system.
The Guyson Microfinishing System can be supplied as a custom tailored installation with many options of cabinet size, loading and access.
Demonstration Facilities are now in place at Guyson lnternational's factory at Skipton, North Yorkshire and trials can be arranged by contacting them. Request a free brochure from Guyson International ...
