People Also ask
What is the surface radius for grinding and polishing on the 6″ and 8″ lap machines?
The surface radius for grinding and polishing on the 6″ All-U-Need and 6″ Slant Cabber is 2-1/4″. The surface radius for grinding and polishing on the 8″ All-U-Need and 8″ Slant Cabber is 3-1/4″. This measurement is taken from the middle arbor hole to the rim of the diamond lap.
Can I sharpen my saw blades?
Yes, you can sharpen sintered saw blades, but we do not recommend sharpening notched-rim or electroplated diamond saw blades. The reason why sintered saw blades need to be sharpened is because the material you are cutting with, such as rock for example, can get impregnated into the sintered matrix over time. This dulls the performance of the saw blade. By sharpening them, you are removing the rock that is impregnated into the sintered matrix and exposing more diamonds.
Sharpen your sintered saw blades with aluminum oxide, a silicon carbide stone, dressing stick or brick. Simply run 3-4 times through the saw blade for a quick fix.
Can I cut curves with your saw blades?
No, all of our diamond saw blades are designed to cut straight lines only. Do not attempt to cut curves with them.
What do “core” and “kerf” mean?
Core is the thickness of the inside of the saw blade (the core), while kerf is the thickness of the saw blade’s rim. When purchasing a saw blade, the dimension of the kerf is what matters most because the kerf determines how thick of a cut you will get. FYI – the kerf gets thinner over time as the saw blade wears away with continuous cutting.
What is the difference between notched-rim diamond saw blades and sintered diamond saw blades?
Our notched-rim diamond saw blades are manufactured using diamond grit that is pressed into the edge of a solid steel core. They have an interrupted surface that improves cutting ability and coolant flow. This process results in a very economical and efficient cutting blade. Hi-Tech Diamond thin notched diamond saw blades and thick notched diamond saw blades are manufactured using this notched-rim process.
Our sintered diamond saw blades are manufactured using a metal-bond matrix that secures diamond grit and extends the full depth of the rim. This sintered technology allows diamonds to continuously expose the edge of the rim as the blade wears away, cut after cut, which increases the life span and durability of these saw blades. Hi-Tech Diamond thin sintered diamond saw blades and thick sintered diamond saw blades are manufactured using this sintered process.
What lubricants should I use with your saw blades?
All of our diamond saw blades are designed to be used with oil or water. Never use a saw blade dry or without a proper lubricant. There are a lot of factors that play a role in what lubricant to use or what lubricant is better for your application, such as what material you are cutting and what saw machine you are using. If you are unsure of what to use, we recommend searching the internet. We found this blog to be helpful: www.gemcutters.org/LDA/TrimSawLubricants.htm
Should I use water with my polishing pads?
While it isn’t necessary to use water with polishing pads, we recommend keeping the Tech-11 polishing pads and final polishing pads slightly damp when you polish. Depending on the material you are polishing, your stone can overheat, getting hot to the touch due to the friction between the stone and polishing pad. As a result of the high temperature produced by the friction, you could possibly burn your fingers or, if you’re using a dop stick, your stone could shift or fall off of the dop stick if the wax melts. If you are using water with your polishing pads, make sure it’s clean.
