WHAT IS A NOVENCO TURQUOISE SLIDEWAY?
Slideway is a proprietary formulation of PTFE material impregnated with bronze and friction reducing additives.
WHAT DOES A NOVENCO TURQUOISE SLIDEWAY DO?
Reduces friction and wear
Reduces damage caused by mechanical problems
Increases accuracy
Extends machine life
Saves energy
HOW DOES A NOVENCO TURQUOISE SLIDEWAY LINEAR BEARING SYSTEM WORK ?
By providing self-lubricating, low coefficient of friction linear bearing surface between two metal interfaces, NOVENCO Turquoise slideway is normally attached to the moving surface by a bonding method.
The Slideway bearing moves with the work table or tool holder along the steel or cast iron mating of the tool way. The static and dynamic friction of NOVENCO Turquoise slideway is nearly the same on both cast and hardened or soft steel ways.
Planers, milling machines, SPMs, sharpers, horizontal & vertical boring machines, hydraulic & pneumatic power presses, press brakes, all types of grinders, radial drills, automatic screw machines, gear hobbers, gear shapers, multi-spindle automats, broaching machines, CNC machines and machining centres.
NOVENCO Turquoise slideway is the solution you have been looking for to reduce the effects of friction on your machine tool's accuracy. It is applicable both for new designs and while rebuilding guideways. The results conform to the machine tool manufacturers & re-builders specifications.
The advantages of NOVENCO Turquoise slideway tape bearings in comparison with traditional solutions are:
Coefficient of Friction: NOVENCO Turquoise slideway has the lowest coefficient of friction as compared to other guiding materials. It is self-lubricating with an unlimited shelf life
Wear: NOVENCO Turquoise slideway has outstanding wear resistance and is recommended for mating with surfaces having a Hardness (BHN) of 180-220 with a Roughness (mm) of Ra<0.6
Contact Pressure: At contact pressures up to 11 N/mm2 it is comparable to other guiding materials and additionally has excellent vibration and damping properties
Stability of Dimensions: NOVENCO Turquoise slideway will not swell or shrink. Its inert property assures the stability of dimensions
Mounting: NOVENCO Turquoise slideway is secured to the metallic guide elements by bonding. The etched side of the tape is easily bondable with a conventional 2-pack industrial adhesive
