GBSJ-1500/1800/2000 CNC Wire Saw Machine

Introduction :

Great Base (GB machine) GBSJ-1500/1800/2000 CNC Wire Saw Machine is single wire saw, can be used for block levering, thick slab cutting, cutting big block into small pcs and ect.

Normal cutting

l Line speed

Adjust according to materials and size of blocks. The harder the material is, or the wider the block is, lower line speed is needed; high line speed will cause polishing of wire, and low line speed will cause oval shape or conicity of beads. Suggested as follow:

Granite Class 1~4: 28-31m/s(the frequency of main motor:50-54HZ)

Granite Class 5 or higher: 24~27m/s(the frequency of main motor：43-48HZ)

Marble and material highly abrasive: 30~33m/s(the frequency of main motor：53-58HZ)

l Current: current is decided by downfeed, cooling water, better below 22A

l Tension: 6MPA（320kg for diameter9mm diamond wire）

l Cooling water: The quantity of water is recommended as 1.5~2 times of the diameters of wire (12-25L/min). Adjust the quantity according to the noise and the dust in the water. Quantity of water should not be too much, which will cause the polishing of wire and decreasing of efficiency.

l Downfeed

Since the block upper face is not flat, in case of wire crashing, breaking, the machine should turn to manual mode, the downfeed should be 20~30% lower than normal. Turn to automatically mode after the wire going into the block.

Adjust the downfeed according not only to cutting type, material, size of block, but also to the condition of diamonds and arc of the wire. The distance of bend of wire between top of wire and both side when you are cutting stone less than 50mm is normal. If more than 50mm, you need to decrease the downfeed. meanwhile according the electric current of main motor to adjust the downfeed. below 22A for main motor is better.

The experimental parameter of granite cutting is:

Class	Efficiency（m2/h）
1~3	0.8~2.5
4	0.5~1
5	0.3~0.7
6	<0.3

Material	Length of block	Hardness	Downfeed (mm/min)
Granite	Less than 1m	Hard	10~15
	Between 1m to 2m		7~10
	More than 2m		4~7
	Less than 1m	Medium	15~18
	Between 1m to 2m		10~15
	More than 2m		7~10
	Less than 1m	Soft	18~25
	Between 1m to 2m		15~18
	More than 2m		10~15
Marble	Less than 1m	Hard	20~25
	Between 1m to 2m		15~20
	More than 2m		10~15
	Less than 1m	Medium	25~30
	Between 1m to 2m		18~25
	More than 2m		15~18
	Less than 1m	Soft	30-35
	Between 1m to 2m		25~30
	More than 2m		18~25

Notice that low downfeed will cause low pressure. The bond of the beads won’t be consumed and the diamonds can’t be exposed continuously, which will lead to polishing problem eventually. High downfeed is easier to cause marks or other slab quality problems. So the downfeed should be controlled properly.

l Block arrangement

It’s highly recommended to cut several soft blocks before cutting a hard block. This method will increase the efficiency and lifespan of the wire.

l About efficiency

As diamond wire is one kind of soft tool, its efficiency is low than disk saw. So do not increase the efficiency too much or it will cause cable breaking, polishing, decreasing of lifespan and quality of slabs.

l Wear of joint

Operators must check the joint and the beads nearby before every cutting. Joint must be changed when worn out or got loose.

l Protection

Prevent the block from falling when cutting finishes. When the cutting is half done, insert enough wedges.

l Regular checking

Check the shape of the beads every cutting, in case of oval shape.

Check the joint and the beads nearby, change the joint when needed.

Check the tension force, within the range of 5-6Mpa
