STORE YOUR DISCS PROPERLY
NORTON HAS SENT OUT A REMINDER ON
how important it is to store coated abra- sives, such as fibre discs, for longer last- ing service. If neglected, it can affect the products performance, longevity and even its safety.
To avoid damaging abrasive products, consideration needs to be given during storage as there is often no special area al- located for storing abrasives. All abrasives, either coated, reinforced or bonded, should be stored in the following conditions:
• dry and frost-free
• kept away from cold and damp
• not exposed to high-temperature vari-
ations or direct sunlight
• within a temperature range of 18°C
and 26°C
• ideal relative humidity of 45% as ei-
ther dry or humid storage may incur product deterioration.
Temperatures and humidity are the
two very important factors influencing
coated abrasive performance and safety. Backings and adhesives are sensitive to climate changes and will gain or lose moisture according to the relative hu- midity of the surroundings.
Excessive humidity may cause the fi- bre backing of a disc to absorb moisture. This increase in moisture may cause the disc to curl up into a convex shape like a taco shell, called ‘cupping’. Discs that are cupped or curled up should never be used. A disc in this condition may snag on the work piece causing it to break. Excessive moisture may also soften the adhesive bond and cause the disc to sud- denly shed or lose large amounts of abrasive grains.
Excessive dryness may cause the disc to curl or arch down in a concave man- ner and become brittle and lose flexibil- ity. To keep your disc flat and safe please follow the list of the proper storage re- quirements for coated abrasive discs:
• store abrasive disc at 40-50% relative humidity and 15-29 degrees Celsius
• coated abrasive disc must be stored at
least 10cms above the surface of con- crete floors, away from open win- dows, out of direct sunlight and away from heat sources such as radiators, steam pipes and air conditioner vents
• protect coated abrasive discs from ex- posure to water or other fluids/solvents • always follow any abrasive manufac-
turer’s storage instructions
• do not drop or in any way damage the
coated abrasive packaging
• if packaging is received damaged, the
product inside must not be used. Re- turn any damaged product to its man- ufacturer
• rotate stock, use on a first-in, first-out basis
• store coated abrasive discs in original packaging and/or in a horizontal manner.
SAPE WELDER HITS THE GYSPOT
THE INBUILT INTELLIGENCE OF THE SAPE
Gyspot inverter allows full automation, offering body shops the ability to in- crease efficiency: brass G-clamp with pneumatic over-opening, easy arm posi- tioning without adjustment and a motor- ised overhanging arm providing a wide working area.
Sape says it is the advanced machine for body shops. Features include:
• light weight of 11.3kg with the G1 arm
• 80mm of automatic opening capacity (20mm at rest)
• manual over-opening of the arm for ac- cess to difficult areas (200mm release) • brass clamp support and arm-base for
optimal electrical contact
• double-action feature for quick arm re-
moval without the use of tools
• automatic cooling connection
• remote-controlled clamp for opening,
welding and adjustments
• lockable gyroscope, ball bearing, inte- grated into the clamp body
• high duty cycle (18 points/min) Options include the G9 arm, which is suitable with auto mode and a single-
point gun.
The adjustable overhanging arm ex-
tends 120 centimetres from the power source with rubber protections at the end of the moving parts. An offset bal- ancer is kept away from the work area.
