A guide to diamond blades

Introduction

Specialist tools such as the OX product range require a similarly specialist support service. Our far ranging experience encom-
passes thousands of diamond tools and our qualified staff can assist your selection from our comprehensive product list to reach
rapid solutions to your specific application problems.

This booklet has been designed to assist in the careful use of our diamond blades so as to ensure their
longevity and safety of use.

Operating Instructions

Important
Before using your OX diamond blade, please read these instructions carefully and ensure they are observed.
1. Check the center bore diameter of the blade corresponds to the spindle diameter of the machine.
2. Check for wear of the blade flanges and machine spindle. Worn parts must be changed before remounting a blade.
3. Mount the blade carefully, ensuring it is correctly positioned and seated on the spindle. Securely tighten the flanges
with the fixing bolt or nut.
4. Rotate the blade by hand to check it is running concentric and does not foul any guarding.
5. If the initial cutting is on hard dense materials such as quarry tiles, engineering bricks, etc., predressing the blade will help to produce
and maintain a good cutting speed. This is done by making several shallow cuts on a coarse abrasive material such as sandstone.
On most materials the cutting speed will remain constant throughout the life of the blade. If however, the cutting speed slows appreciably,
redressing will restore it.
6. Tilting or twisting of the saw should be avoided during the cutting operation as this will exert pressure and stress on the steel center.
Stress and side pressure can cause damage to the steel center and segments.
7. Overfeeding is when attempts are made to force the blade to penetrate faster than it will naturally accept. Overfeeding causes rapid heat
generation which in turn has a major adverse effect on the diamond segments. Over-heating and therefore overfeeding must be avoided.
8. Blades up to 300mm diameter are primarily designed for dry cutting but can also be used wet. They will penetrate steel reinforcing
embedded in concrete but are not suitable for cutting bare metals of any kind.
9. If any problems are encountered, your supplier should be contacted immediately.
