EQUIPMENT DESCRIPTION
The diamond wire saw is designed to cut submerged pipe of varying materials and thicknesses. The machine operates on hydraulic power, and is controlled remotely using the Wachs topside control panel (TCP).
The saw uses a continuous-loop diamond cutting wire and a hydraulic feed system that advances the cutting wire through the pipe. Using a wire rather than a blade provides more reliable cutting on varied pipe materials, and helps avoid binding of the cutting mechanism if the pipe bends and pinches while the saw is engaged.
Current versions of E.H. Wachs Company manuals are also available in PDF for­mat. You can request an electronic copy of this manual by emailing customer service at sales@ehwachs.com
.
The diamond wire saw required constant cooling of the wire during cutting. The machine is specifically designed for subsea or other underwater cutting applications, but it can be used for non-submerged uses if adequate coolant is applied to the wire. The machine can be supplied with cus­tomized cooling spray attachments that use tap water or other available coolant.
The diamond wire saw has three hydraulic drive circuits:
E.H. Wachs Part No. 10-010-MAN, Rev. 1-0310 3
Diamond Wire Saw User’s Manual
NOTE
The model name indicates the pipe size capacity. The first two digits are the largest pipe, and the second pair of digits is the smallest. For example, the WS-3616 saw will cut pipes from 16” to 36” (406 to 914 mm) O.D.
Cutting drive: operates the drive wheel that drives the cutting wire.
Feed drive: operates the bow holding the wire drive sys­tem, to feed the wire through the pipe and retract the bow when finished cutting.
Clamp drive: operates the clamping arms that secure the machine to the pipe during cutting.
Separate controls and gauges for each circuit are provided on the TCP, described later in this chapter.
Diamond Wire Saw Models
Various wire saw models are available, each designed to cut a range of pipe sizes. All models operate in a similar man­ner. However, the WS-8460 model has some different fea­tures, which are highlighted throughout this manual.
The following table lists the models and capacities.

Figure 1-1. The photo shows the cutting wire drive system components.
The WS-8460 has an addi­tional idler wheel next to the drive wheel.
The drive wheel is operated by the hydraulic drive motor to turn the wire around the cutting system loop. It is mounted on a pivoting fixture used to adjust the tension of the wire. The tension is set using a knob on the fixture, which also positions the wheel for installing and removing the cutting wire.
The tension wheel is on a pivoting, spring-loaded fixture that maintains wire tension. The other two idler wheels are fixed at the bottom of the bow where the cutting wire engages the pipe.
The wire is a custom-made loop for the size of the saw. Spare wires can be ordered from E.H. Wachs.
Feed System
A feed drive mechanism on the main frame of the machine drives the bow and cutting system up and down to perform the cut and retract the bow after cutting. The bow rides on feed rails and is driven by a feed screw in the center of the frame. Figure 1-2 and Figure 1-3 show the main feed sys­tem components.

Figure 1-3. The feed system components are shown. The feed block is attached to the saw bow.
The top of the feed screw has a drive nut to allow the feed to be operated manually, and a clutch in the top coupling dis­engages the feed screw if the feed drive jams or reaches the end of travel.

Feed control actuator Tension wheelTension spring
Figure 1-4. Use the manual feed nut to move the saw bow if it cannot be operated using hydraulic power. T urn the nut clockwise to retract the bow away from the workpiece.
The feed system has a self-adjusting speed control feature. A hydraulic actuator on the tension wheel fixture measures the deflection of the wire as it cuts. If the feed speed is too fast, the increased wire deflection trips the actuator, which slows down the feed rate. This allows the cutting action of the wire to catch up. At maximum deflection of the wire, the actuator will stop the feed motion for as long as necessary.
Figure 1-5. The actuator controls the feed rate by measuring the deflection of the cutting wire.

Clamping System
An adjustable clamping system allows you to configure the machine for pipe sizes within each model’s range. The two clamping arms are attached to the main frame with two­pronged forked pins that are removable to reposition the arms.
The clamping arms are engaged by hydraulic cylinders mounted to the frame. When the cylinder rods are extended, the clamps pivot inward to grip the underside of the pipe and hold the machine securely to it. Figure 1-6 illustrates the clamping operation.
See “Adjusting Clamp Arms for the Pipe Size” later in this chapter for information on the clamp position settings for each wire saw model.

Figure 1-6. The photo shows the wire saw in position for clamping on a test workpiece. When the hydraulic cylinder is extended, the clamp arm pivots and closes on the pipe. Both clamping arms operate together.
Chapter 1, About the Diamond Wire Saw: Equipment Description
Figure 1-7. The photo shows the clamping cylinder extended and the clamp arm secured against the pipe.
The frame of the machine has clamp shoes attached that the machine rests upon when installed on the pipe. These shoes are made of a compressible composite material that deforms slightly under pressure to create a secure, slip-free grip on the pipe when the machine is clamped.

ADJUSTING CLAMP ARMS FOR THE PIPE SIZE
The clamp arms are attached to the main frame using forked pins that go through two holes in the frame. Multiple sets of holes allow the arms to be mounted in various positions.
The hole pairs for each position are stamped with the size of the largest pipe for that position. Refer to the following sec­tions for the pipe size settings for each saw model.

Positioning the Clamp Arms
Make sure the saw is sitting horizontally on a level surface before you adjust the clamp arms.
Remove the spring clips from both pin ends of the
1.
forked pin, then pull the forked pin out of the frame.
Do not attempt to change the clamp arm positions while the saw is in a vertical position. The clamp arms may fall when the pins are removed, resulting in personal injury and equipment damage.
