Standard Equipment

• Servo Drive — Independent high-accuracy control of spindle axis; reduced components and maintenance; radial die line-up via motor control from the HMI.
• Front L Support with Front Bar Feed Fixture — Adjustable work-holding fixture attached to the machine front.
• Spring Loaded Rear Stop Assembly with Base — Positions parts for infeed rolling; spring loaded to allow slight part movement.
• Versa III Auto Oil Lubrication System — Automatic feed slide oiling system.
• Hydraulic Slow Release Valve — Releases rolling force gradually to prevent thread form deformation during heavy rolling.
• Spindle RPM Tachometer — Displays spindle RPM.

Available Options

• Thread Length Control Limit Switch — Allows positioning of thread length when rolling part of a rod.
• Radial Die Line-Up Coupling — Permits separate rotational adjustment between spindles for infeed or helical dies.
• Part Hold Down with Spring Loaded Stop — Hand-operated holder to keep parts on support blade and maintain operator safety.
• Tie Arm Hydraulic Stop Block Assembly — Adjustable mechanical stop to prevent over-rolling tail-ends of thrufeed bars.
• Enclosed Toe-in Indicator — Reference for adjusting main head die for part taper.
• Outboard Roller Supports (1 set/2 pcs) — Provide additional part clearance behind spindle supports.
• Center Stands (1 set/2 pcs) — Support the center tube.
• Center Support Tube (one required per size) — Guides parts exiting the back of the machine; one per size.
• Upper Support Holder — Captures material between dies and support blades for high-speed studs and threaded rod.
• Feeding and Receiving Fixtures — Custom feeding and receiving fixtures available.
