DIAMOND BLADES

LORTONE offers diamond blades in several different styles for specific needs. Our blades are made exclusively with high quality diamonds under tightly controlled conditions. Each is the finest made for its purpose and will give prolonged life if used with proper care. Blades are individually edge ground, tested for tension and balance and painted for protection. We believe our blades to be superior in quality and performance to any competitive blades made anywhere in the world.


Select the proper blade

Choose a blade for the type of cutting you do. Material properties, machine Characteristics and coolant type will influence blade choice. Delicate trim work or valuable material requires thin blades. Use a thicker blade when material loss is not as important or where extra durability is required.


Select the Proper Coolant

Make sure the coolant you choose is combatable with your equipment. If you are not sure which coolant to use, ask the manufacturer. Oil is the standard coolant for long life and fast cutting and a must for slabbing large sections of hard material. Water offers reduced odor and easier cleanup than oil but at a slight loss of performance and life. Use blades without coolant only where water and oil would damage the specimen and only when specifically designed for such use.


 

TAKE CARE OR YOUR BLADE

* Make sure the blade fits. Check to make sure the diameter and arbor size is correct for your saw.

* Use the proper blade flanges for your machine. Check to make sure the flanges are free of burrs.

* Check for play in the arbor. Loose arbor bearings can cause a blade to pound or dish.

* Use the proper coolant. Kerosene, diesel fuel, and antifreeze do not provide sufficient lubrication.

* Use the proper RPM. Run blades at manufactures suggested rpm.

* Dress the blade when new and periodically during use. This removes glaze and expose new diamond. Use a good quality dressing stock such as CASCADE Dressing Stick.

You can calculate the equipment shaft speed for other motor speeds by multiplying the motor RPM by the motor pulley diameter and then dividing by the equipment pulley diameter.


DETERMINING SAW SPEEDS

To make certain your saw runs at the correct RPM's for the diameter of a blade, use the chart above. Chart is based on motors running at 1750 RPM.

Left hand column lists diameter of the motor pulley, while the top column across lists the diameter of the pulley on the equipment. With these two pulley diameters, you can locate the RPM speed of that particular setup. For instance, a motor pulley diameter of 3.0" with an equipment pulley of 2.5" will operate a saw blade at 2100 RPM's. Using the chart Guide to Operating Speeds for Blades, you will find this is a proper speed for blades 5" to 10" in diameter. But if your saw takes either a 4" blade or one with 12" or more in diameter, you will need to change pulleys.
