Standard Equipment

• Servo Drive: High accuracy independent control of spindle drive axis. Reduced components and maintenance. Radial die line-up via motor control from the HMI interface.
• Versa III Auto Oil Lubrication System: Automatic feed slide oil system.
• Hydraulic Slow Release Valve: Used in heavy rolling, function releases rolling force slowly to prevent deformation of thread form.
• Spindle RPM Tachometer: Reads the RPM of the spindle.

Available Options

• Thread Length Control Limit Switch: Used when rolling threads on part of a rod; allows positioning of thread length by limit switch placement.
• Radial Die Line-Up Coupling: Permits separate rotational adjustment of one spindle to the other for matching infeed or helical slow feed dies; keeps die faces even when desired.
• Front "L" Support including Front Bar Feed Fixture: Adjustable work holding fixture that attaches to front of machine.
• Spring Loaded Rear Stop Assembly with Base: Spring loaded part stop positions part to the desired location for infeed rolling and allows slight part movement.
• Part Hold Down with Spring Loaded Stop: Hand operated; holds part on support blade so fingers are at a safe distance during rolling.
• Tie Arm Hydraulic Stop Block Assembly: Adjustable mechanical stop that prevents over-rolling the tail-end of thrufeed bars.
• Enclosed Toe-in Indicator: Gives a reference for adjusting the left main head die for part taper.
• Hydraulic Slow Release Valve (option): Used in heavy rolling to release rolling force slowly to prevent deformation of thread form.
• Outboard Roller Supports (1 set/2 pcs): Behind the spindle support blocks; gives more part clearance for large head bolts, etc.
• Center Stands (1 set/2 pcs): Supports the center tube.
• Center Support Tube (1 needed for each size): Contains parts out the back of machine; one needed for each size.
• Upper Support Holder: Captures material between dies and work support blades for running high-speed studs and threaded rod.
• Feeding and Receiving Fixtures: Custom designed feeding and receiving fixtures for specific needs.
