Strongsville, Ohio, USA, February 18, 2019 – Rafter Equipment Corporation has shipped an RT-4000 HFI weld squeeze box to a major North American DOM tube producer. The new 4-roll design continues with the company's preference for "dead spindle" weld roll shafts whereby the bearings are pressed within the roll tools. This unit replaces an old 4-roll design that had "live" spindles for the two lower rolls. The bearings for these spindles had become very expensive and time consuming to replace. Having the bearings now in the rolls allows for frequent inspection and easy replacement when necessary.
The new design includes a removable faceplate assembly that allows for offline changeover of the roll tools while laying the assembly flat in a horizontal orientation. This method is much easier than on the mill in an upright or vertical orientation. Powered shot pins secure the faceplate assembly and allow for a quick engagement without the use of hand tools.
In addition, all roll adjustments are accessible from the operator's side of the machine. The heavy-duty construction will accomodate tubes up to 3.500" OD x 0.300" wall thickness x 75 KSI material yield strength.
Strongsville, Ohio, USA, February 11, 2019 – Rafter Equipment Corporation has shipped four (4)

Strongsville, Ohio, USA, February 1, 2019 – Rafter Equipment Corporation has shipped a RT-2000L
2-roll HFI weld squeeze box to a North American tube producer. The weld box is a retrofit to an existing Yoder M-1-1/2 tube mill that is being converted from ERW to HFI welding. The product mix on this mill is perfect for a simple 2-roll solution.
Strongsville, Ohio, USA, January 22, 2019 – Rafter Equipment Corporation has shipped a
RT-3000S/3500S high-speed HSS tube mill to a major North American tube producer. The mill is capable of making 2-1/2" square x 0.250" wall HSS tube at 400 FPM and lighter gauges up to 600 FPM. The mill is rafted for quick-changeover and includes an automatic universal drive shaft handling system. The reshaping section includes heavy-duty RT-3500S driven and idle side roll stands. A double-sided turkshead straightener with 2-axis remote adjustment with position feedback allows the operator to make straightness corrections from the downstream cutoff station. Offline raft changeover tables were included. An integrated rolling trolley with hydraulic push/pull device makes for quick and easy handling of the outboard roll stand housings.
UPDATE May 17, 2019: Line commissioning began this week and the mill performed as expected.
Strongsville, Ohio, USA, November 11, 2018 – Rafter Equipment Corporation has supplied a retrofit
RT-2500S 2-roll HFI weld squeeze box to a major North American mechanical tubing producer.

The weld box is sized for up to 4.500" OD x 0.160" wall HSLA tube. It is significantly more robust than the unit it replaced. Operator feedback on the new unit has been very positive.

Strongsville, Ohio, USA, March 30, 2018 – Rafter Equipment Corporation has shipped an RT-3000 Single-Tool HFI Weld Bead Upset Trimmer with Bead Winder to a North American custom roll form parts producer. The equipment includes a cam actuated quick-lift feature to raise and lower the trimming tool automatically when the mill stops or manually when a coil end joint passes underneath. The use of a cam motion locks the tool in the down position mechanically. It also returns the tool to the preset trimming position automatically after it has been raised. The lower support roll tool was contoured to match the direct-welded profile section.
The Bead Winder is mounted to the top surface of the trimmer. It includes a variable speed motor with a slip clutch mechanism for optimum tension control. This feature greatly reduces bead breakage during winding. A pneumatic push-off mechanism breaks the cooled bundle free of the winder tines for easy disposal.
Strongsville, Ohio, USA, February 16, 2018 – Rafter Equipment Corporation has shipped an RT-4000S single-sided turkshead straightener with 2-axis motorized adjustments to a major North American heavy-wall tube producer. The turkshead is capable of straightening up to 3.500" OD x 0.300" wall (88.9mm OD x 7.6mm wall) tubing. It includes motorized up/down and left/right adjustment so that tube straightness can be controlled from a remote downstream position using a simple joystick device. Linear displacement transducers (LDTs) indicate movement and position for optimum straightness control on the included remote operator's console.
The turkshead includes a removable faceplate design that allows for the roll tooling to be exchanged offline while laying down. A second faceplate was included for enhanced quick-change capabilities.
Strongsville, Ohio, USA, February 5, 2018 – Rafter Equipment Corporation continues to please customers with the company's robust 3-roll HFI weld squeeze boxes.

The stands will reshape round tubing formed with a bottom-of-tube constant datum into equivalent squares & rectangles with a constant centerline datum. The maximum reshaped tube will be 2½” square x 0.135” wall thickness.
The stands represent a new design with increased robustness and easier setup and operation. The company worked with the customer to determine what improvements could be made over the previous design while still keeping within the original budget.
