Contractor ’ s Corner
ASSESSMENT EXCELLENCE Application specialists and technical sales advisors at reputable providers are available to conduct site visits and assess a company ’ s applications and requirements , as well as provide guidance on the machine and tool combination that will offer the most cost-effective solution .
As an example , recently a PFERD application specialist went to a site to assess the customer ’ s unusually high usage of tungsten carbide burrs . It was determined that the customer recently replaced their pneumatic tool drives and price played a major role in their decision-making .
During the investigation , it was determined that the new pneumatic tool drives were of the incorrect rotational speed for the tungsten carbide burrs being used . The machines were rated at 25 000 RPM – whereas the consumables had an optimum operating speed of 16 000 RPM . This incorrect operating speed led to heat build-up , premature wear and in some instances , product failure .
When replacing new tool drives it is recommended to do so with the correct operating RPM and a material specific consumables ideally suited for the material and application . The immediate difference in the handling , performance and comfort for the operators will be evident .
In this example , further in-production testing resulted in the customer changing over to the recommended machine and consumable combination . While initial set-up costs were higher , the customer noticed a significant overall cost reduction due to improved product service life and productivity . The proof was thus in the performance and the balance sheet .
When used correctly , premium brand product ranges offer greater lifespan , better performance and superior cost efficiencies . RACA
