SwivelJet® Flexible Coolant Delivery Systems

What is SwivelJet?

SwivelJet was designed to give you a better coolant nozzle line choice. 

It delivers a strong, cohesive jet of coolant to the grinding or machining area. It’s also designed to be flexible for setup and be tightened to stay rigid. And finally, it is designed to reduce costs and increase profits.

The line is made of solid brass. As designed, a single hex line will hold its geometry at 200 psi. The links swivel up to 30 degrees each way, giving the flexibility needed for almost all setups. Adding or removing a link takes less than 20 seconds. A new knurled system allows for hand-tightening with no loss to line geometry without wrenches or tools.

How does SwivelJet Work?

The SwivelJet line uses a series of links made from solid, recyclable brass. Links can be added or removed easily to create longer or shorter coolant lines. Each link has two swivel joints. When the line is first installed, the operator can set the desired pressure on the swivel joints.   

Once installed, the line can be easily moved into position by hand and tightened into place with either a wrench (hex line) or by hand (knurled line).  

The lines are available with several types of nozzles: a round swivel or "bullet" nozzle, a flat swivel nozzle, or a two-angled flat nozzle. The coolant jets created by the nozzles use coherent jet fluid principles used in fire hose nozzle technology. This keeps the coolant together, reducing the amount of air brought into the machining or grinding zone.

Finally, standard NPT and BSP manifold fittings are used to thread the lines into a manifold.  

Tests performed on popular CNC tool and cutter grinders resulted in cycle time reductions of 25 to 55 percent on applications using diamond and CBN wheels. Used in machining, SwivelJet reduces double-cutting of chips while at the same time allowing for faster cycle times. Tool life will go up while costs to manufacture go down.

The End Results

The SwivelJet line and nozzle are best used in an enclosed CNC. The amount of coolant pressure created by the nozzle puts more coolant into the machining and grinding zones. As a result, more coolant is usually displaced as it hits the tool or wheel.  This does not usually lend itself to use on manual machines that are open to an operator.

The lines can be used with the manifolds supplied by the manufacturer, or with a coolant manifold designed to put the lines where they need to be.

With SwivelJet, the stream of coolant leaving the nozzle does most or all of the following for grinding:

  •  Reduce cycle time
  •  Reduce wheel loading
  •  Reduce heat in grinding zone
  •  Reduce wheel dressing
  •  Reduce wear on the wheel
  •  Increase the coolant pressure (psi) at the nozzle
  •  Reduce heat and metal weakening of the workpiece
  •  Increase the distance the line is placed from the wheel
Five nozzles for coolant delivery: Bullet, straight, flutemaster, gearmaster, power

Nozzle Types

SwivelJet offers several different nozzle types for different coolant patterns.  All types of nozzles are available in both our SW1 and SW2 coolant lines, with the SW1 lines offering multiple sizes of the wide nozzle patterns.

The bullet nozzle provides a concentrated flow of coolant in a compact round stream. It will maintain a coherent flow for up to 12 inches or more. It includes a swivel joint to allow for pinpoint direction control.

The flat nozzle provides a straight fan flow of coolant for broad coverage. The corners of the nozzle are radiused to provide clean (non-distorted) delivery at extended distances. It includes a swivel joint to allow for easy positioning of the coolant flow.

The Flutemaster nozzle is a specially adapted flat nozzle. It is designed at a 60-degree angle from the plane of the coolant line to provide a straight fan flow of coolant to target broad coverage for the face of a grinding wheel or cutting tool. The corners of the nozzle are radiused to provide clean (non-distorted) delivery at extended distances.  It is supplied with a swivel joint to allow for easy positioning of the coolant flow.

The Gearmaster nozzle is a specially adapted flat nozzle. It is designed at a 60-degree angle from the plane of the coolant line, similar to the Flutemaster nozzle, and rotated 90 degrees around the axis of the coolant line to provide a straight fan flow of coolant to target broad coverage for the sides of a grinding wheel or cutting tool.

The corners of the nozzle are radiused to provide clean (non-distorted) delivery of extended distances. It is supplied with a swivel joint to allow for easy positioning of the coolant flow.

The power nozzle is designed to provide a concentrated flow of coolant in a compact round stream with a different geometry than the bullet nozzle. The delivery portion of the nozzle is shorter than the bullet nozzle to provide a wider stream. It’s supplied with a swivel joint to allow for pinpoint direction control.

Hex and Knurled Line Finishes

SwivelJet coolant lines come in both hex tightening and knurled tightening options.

Hex Coolant Line

Hex

The hex geometry allows you to use a wrench when tightening a Swiveljet coolant line into position. The hex allows for a tighter connection because you can use a wrench to apply more torque on the fittings. This style is popular with fixed installations, higher pressure applications and for the SW1 lines, as they are a larger diameter.

Knurled Coolant Line

Knurled

The knurled geometry allows for finger-tightening of the Swiveljet coolant line into position. The knurled finish provides an easy-to-grip surface to allow an operator to grip the line and tighten the fittings. This style is popular for frequently adjusted installations and for the SW2 lines, since they are smaller in diameter and easier to tighten with only finger pressure.
