The Centre of Excellence
is based at Taylor Hobson's
headquarters in Leicester and offers a comprehensive
metrology service for customers. These services include:
- Product and theory training either at Taylor Hobson or your premises.
- Instrument and metrology advice.
- A trial measurement service to help customers decide which product to buy.
- Lectures and presentations
The Centre of Excellence team has access to various Taylor Hobson instruments to measure surface texture, roundness, form, squareness, etc. This allows them to provide the metrology solutions for all kinds of problems, enabling them to advise you which intrument you need.
Metrology
Solutions
The Centre of Excellence
runs customised training courses for all Taylor Hobson customers.
General
Roundness and Surface Courses
Run to give you an
insight into the measurement of surface finish and roundness.
Instrument
Training
Essential for the
customer who wants to get the most from their Taylor Hobson instruments.
Taylor Hobson's Centre of Excellence provides a measurement service which develops solutions to your metrology problems. Some examples include:
- Erosion of the
human tooth by orange juice
- A customer was carrying out research, investigating the amount of erosion by acidic foodstuffs. By using a Form Talysurf Series with Y-Stage and Talymap 3D software, it was possible to view the erosion after a short period of time.
- Minute devices
designed to keep arteries open - called Stents
- The customer required various measurements of diameter, strut dimensions, angle etc. They also asked for particular requirements, such as an automated process, and a pass or fail system. The measurements were carried out on a Primus using the camera with zoom lens option, and a rotary table.
- The glaze defects
on ceramic tiles
- The customer required 3D analysis of the surface finish of several ceramic tiles. The solution to this problem was to use a Talyscan 150 measuring system.
- Explosive fuses
- The explosive was not firing fully, and the customer suspected a problem with the fuse body. They decided that this would need to be checked, and required measurements of cylindricity, straightness and parallelism. These measurements were carried out on a Talyrond 265

Surface Finish and Roundness Metrology course details
These courses are specifically aimed at users, managers and designers who are seeking a practical, “hands on” knowledge of the subject from the experienced user’s perspective.
Taking place at our
Centre of Excellence in Leicester, England, the courses are being given
bythe Centre’s Metrology Engineers - experts who have many years’
experience in solving real measurement problems.
Our engineers have access to the latest measurement technology and surface
finish roundness instruments.
Bring your own
measurement query
We invite
all attendees to bring their measurement problems along for discussion
during the “hands on” sessions which form part of the courses.
For any solutions that we can’t identify at the time, we can arrange
for a measurement report at a later date.

Instrument Training
Are you getting the
most from your Taylor Hobson instrument?
Do you need more information on data sampling, applying filters or maybe
the correct use of parameters?
Taylor Hobson's team of experts run regular courses on individual instruments which are tailored to help you get the maximum from their instrument.
Due to detail, these courses have a maximum class size of three people. To get the most out of these courses, you are invited to bring along components that you need to measure..
