Precision built components and medical implants can now be cleaned and finished to the highest standards using the ultra-fine micro-nozzle pressure feed system
Small and difficult to reach areas such as those frequently found within precision built components can now be cleaned and finished to the highest standards using the ultra-fine micro-nozzle pressure feed system introduced by bead blasting machinery manufacturers Guyson International.
The Guyson Pencil Blaster system is equipped with two pencil shaped, micro blast nozzles with internal diameters as fine as 0.8mm, 1.2mm or 1.8mm to pressure blast ultra fine media of a particle size of less than 300 microns.
Controlled by a common foot pedal and selected by a switch system, each micro nozzle operates independently from one of two pressure vessels, each can contain blast media selected to produce the finish required, eg, one coarse and one fine. Operational blasting time can be extended to several hours, without replenishing media, by fitting additional media reservoirs, available as an optional extra, which screw on to the existing media containers.
A compact unit, the Pencil Blaster measures only 300mm high by 300mm wide and 230mm deep and has been designed primarily as a retrofit spot blast-finishing tool to complement most blast cabinet installations.
Available as either a single or twin micro nozzle system, it is now being factory fitted by Guyson as an optional modification to any new bead blasting cabinet purchased from its standard Formula or Euroblast range.
It can also be used as a freestanding blast unit, providing all necessary protective measures are taken. Typical usage includes the deburring and deflashing of precision parts, selective conformal coating removal from printed circuit boards, micropeening, cleaning orifices in turbine blades and the removal of metallic deposits from quartz glass.
Dental laboratories and medical departments have also found them useful for surface preparation on medical implants, cleaning and deburring of orthodontic devices and producing specific 'no glint' satin finishes to surgical instruments.
Also many museums and art restorers have installed units for cleaning artefacts, sculptures, jewellery and fossils and etching glass surfaces.
