Use as a reference and adapt for your machine and needs.
Boart & Wire is known for consistent excellence in manufacturing diamond wire. For cutting blocks, CNC profiling, multi-wire saws, and quarry. Call Miles Supply to ascertain the right wire for you. There are many factors; we may want to know your block size, the stone material you are sawing, type of machine, and what sort of final product; square, slab, or profile work. Priority of production speed vs cost.
MULTIWIRES / SINGLE WIRE
Parameters for starting a new wire(s) (with soft granite doing 3 cuts if possible)
• 1st cut at 24 m/sec of linear speed wire
• 2nd cut at 25 m/sec
• 3rd cut at 26 m/sec
Ideal Cutting speeds after break in process remain at 26-27 m/sec, do not exceed unless told differently by Miles Supply Rep
NO MORE THAN 7 TO 9 CM OF ARC IN WIRE IF MORE THAN 9 CM OF ARC REDUCE CM/H
PLEASE CALL YOUR MILES SUPPLY REP FOR SERVICE OR TROUBLE SHOOTING
text from the chart pictured above:
Wire Tension- 260KG or 573 Pounds
Wire Arc- 7-9 CM, if wire is exceeding this slow down CM/H cutting speed!
PLEASE USE THIS SPEED CHART BELOW TO DETERMINE CUTTING SPEED IN CM/H. USE AS A STARTING POINT AND POSSIBLY INCREASE OR DECREASE SPEEDS DEPENDING ON WIRE ARC!
Class 2 stone (Grey, Black, White, Pink, and Brown) – Speed CM/H 1.6 divided by length of the block in meters
Class 3 Stone (Red, Blue, and Multicolor)- Speed CM/H 1.4 divided by length of the block in meters
Class 4 Stone (Gold) – Speed CM/H 1.1 divided by length of the block in meters
Class 5 Stone (Quartzite) = Speed CM/H .6 divided by length of the block in meters
Example 1: You are cutting a block of Class 2 stone that measures 8 feet long. Convert 8 feet to meters which is 2.43 meters. Then take 1.6 from the chart above and divide that by 2.43. That gives you .658 so your speed would be 65-66 cm/h
Example 2: You are cutting a block of class 5 stone that measures 4 feet long. Convert 4 feet to meters which is 1.21 meters. Then take .6 from the chart above and divide that by 1.21. That gives you .495 so your speed would be 49-50 cm/h
