Model: M2 Ø0.5 MM RUBY BALL, TUNGSTEN CARBIDE, L 20 MM, EWL 7 MM
MPN: A-5003-1345
Renishaw M2 Ø0.5 MM Ruby Ball, Tungsten Carbide Stem, L 20 MM, EWL 7 MM Styli New With 1 Year Warranty.
Straight styli are designed to inspect simple features where direct, unobstructed contact with a measured surface is possible. A tungsten carbide stem provides exceptional rigidity, particularly for styli with small ball and stem diameters. Ruby is regarded as the industry standard for stylus tips. It is one of the hardest materials available and suitable for most applications. Due to adhesive pickup, ruby tips are not recommended for scanning aluminium parts.
Equivalent to Q-Mark part number: TM2-0520-07.
A few simple rules can be applied to maximize accuracy for most probing applications.
| Thread | M2 |
|---|---|
| Ball dia | 0.5 mm |
| Stem material | Tungsten carbide |
| Tip material | Ruby |
| Holder material | Stainless steel |
| Centre styli | N |
A= ball diameter = 0.5 (0.02)
B = overall length = 20.0 (0.79)
C = stem diameter = 0.3 (0.012)
Renishaw uses a standard description of overall length, measured from the rear mounting face of the stylus to the centre of the ball.
This is measured from the centre of the ball to the point at which the stem will foul against the feature when measuring 'normal' to the part.
A few simple rules for stylus selection can be applied to maximize accuracy for most probing applications
The more the stylus bends or deflects, the lower the accuracy. Probing with the minimum stylus length for your application is the best option.
Every time you join styli and extensions, you introduce potential bending and deflection points. Try, wherever possible, to keep to the minimum number of pieces possible for your application.
There are several reasons for this:
EWL can also be affected by assembly tolerances. For this reason Renishaw styli are assembled to exacting standards in controlled conditions.
This is by far the best price you will find on a Renishaw M2 Ø0.5 mm Ruby Ball, Tungsten Carbide Stem, L 20 MM, EWL 7 MM Styli New With 1 Year Warranty.
