Stylus for CMM and CNC Touch Probes

◆What is the function of stylus

As industry has developed its requirement for increasingly diverse and complex manufactured parts, measurement systems have had to work hard to keep up.
High speed and high performance measuring machine scanning system can guarantee in a very short period of time to achieve very accurate measurements. Qidu help you maximize your productivity and maintain the highest quality.
Successful measurement depends very much on the ability of the probe's stylus to access a feature and then maintain accuracy at the point of contact. At Qidu, we have used our expertise in probe and stylus design to develop a comprehensive range of CMM and machine tool styli to offer you the greatest possible precision.

◆What is a stylus

A stylus is that part of the measuring system which makes contact with the component and workpiece, causing the probe's mechanism to movement, The generated signal enables a measurement to be taken. The feature to be inspected dictates the type and size of stylus used in all cases, however, maximum rigidity of the stylus and perfect sphericity of the tip are critical.
To achieve this, Qidu's stylus stems are fabricated on CNC machines to meet the high quality standards. Great care is taken to ensure that the maximum stiffness of stylus, whilst the quality of stylus is optimized to suit QIDU's wide range of probes.
Qidu stylus balls are produced to the highest standards and are bonded to the stems in such a way as to ensure maximum joint integrity.
The performance of your measurement can easily be degraded if you use a stylus with poor ball roundness, poor ball location, bad thread fit or a compromised design that allows excessive bending during measurement. To ensure the integrity of the data you gather, make sure that you specify and use a stylus from the full range of Qidu styli.

◆How to choose a stylus
To maintain accuracy at the point of contact we recommend that you:
1.Choose short styli
The more that a stylus bends or deflects, the lower the accuracy.
Use as short as possible stylus is your best option.
2.Minimize joints
Every time you join styli and extensions, you add potential bending and deflection points. Try, wherever possible, to reduce the number of components in your application.
3.Choose the ball as large as possible
3.1. It maximizes your ball/stem clearance thereby reducing the chances for false triggers caused by 'shanking out’ on the stylus stem.
3.2. The larger ball can reduce the effect of the surface finish of the component being inspected.

◆What is the stem material
■Stainless steel
Stylus stems manufactured from stainless steel are used widely for styli with ball/tip diameters of 2 mm or greater and with lengths up to 30 mm. Within this range, one piece steel stems offer the optimum stiffness to weight ratio, giving adequate ball/stem clearance without compromising stiffness with a joint between the stem and threaded Body.

■Tungsten carbide
Tungsten carbide stems are best used for maximizing stiffness with either small stem diameters required for ball diameters of 1 mm and below, or lengths up to 50 mm Beyond this, weight can become a problem and stiffness is lost due to deflection at the stem to body joint.

■Ceramic
For ball diameters greater than 3 mm, and lengths over 30 mm, ceramic stems offer stiffness comparable to steel but are significantly lighter than tungsten carbide. Ceramic stemmed styli can also offer additional crash protection to your probe as the stem will shatter in a collision.

■Carbon fibre
There are many grades of carbon fibre materials. However, Qidu's material combines optimum stiffness characteristics, both longitudinally and in torsion,with extremely low weight. Carbon fibre is inert and this combined with a special resin matrix, provides excellent protection in the most hostile of machine tool environments.
Qidu's material is ideal for maximizing stiffness for styli above 50 mm in length. It is the optimum stem material for high accuracy strain gauge technology probes with excellent vibration damping characteristics and negligible co-efficient of thermal expansion.
