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.

Available Options

• 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.
• Thread Length Control Limit Switch - Used when rolling threads on part of a rod; allows positioning to obtain desired thread length.
• Radial Die Line-Up Coupling - Permits separate rotational adjustment of one spindle to the other for matching of infeed or helical slow feed dies.
• 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 - Positions part for infeed rolling and is spring loaded for 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.
• Outboard Roller Supports (1 set/2 pcs) - Behind the spindle support blocks; gives more part clearance.
• 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.
