9.1 Introduction
Now that you own the most versatile and reliable surface preparation and polishing machine
on the market, you need to understand the way it gets the job done. Diamond tooling
provided by Substrate Technology has been designed and tested for use with the Prep/
Master
® line of machinery exclusively. We have assembled a system that takes the guess
work out of the industry that is Concrete Surface Preparation and Polishing. These products
are proprietary, original creations that are made to work consistently so that you have
success on your first and every concrete grinding or polishing project thereafter.
9.2 Why a Diamond Cuts
A diamond’s ability to cut is directly influenced by weight, speed, and diamond size. As any
one of those factors are reduced or increased the remaining two need to be modified to
accommodate that change without affecting performance. Diamond tooling cuts by using the
aggressive characteristics of synthetic or natural diamonds. As the diamond chip is moved
across the work surface, its inherent strength causes a scratch in the material equal to the
amount which the diamond chip is protruding from the matrix.
The matrix that holds the diamond is very important to the diamond chip’s ability to cut as
well as be retained so that the diamond can be held in place for as long as possible to keep
lifespan at an acceptable level. During the grinding process, the matrix holds the diamond
by eroding away only at the leading edge of the diamond as a function of abrasion, but the
