STANDARD EQUIPMENT / FEATURES

• The Hyperloop System will be replaced with a Fanuc 16i "CNC" Controller, with Color Display
• The Fanuc CNC will Control the Following Axis:
- Work Table Rotation (no change gears required)
- Cutter Spindle Rotation
- Work Table Infeed
- Cutter Spindle Stroking Speed
- Stroke position
- Stroke Length Adjustment (from CNC Control not Top of Machine)
• Manual Pulse Generator (MPG) can Control All Six "CNC" axis including stroke length adjustment
• Both Work and Cutter Spindle have Rapid Rotation for Indicating Purposes
• Four Cut Capability Selectable for 1-cut, 2-cut, 3-cut & 4-cut Operations with Stroking Speed, Depth Feed Rate, • • • • Depth of Cut and Rotary Feed Infinitely Variable and Preset for Each Cut
• High Output, Quick Return, Infinitely Variable Stroking Drive with Adjustable Return Ratios as follows:
- 12 to 300 SPM at 2:1 ratio
- 12 to 250 SPM at 3:1 ratio
• Rotary Feed: The Custom Software on the Fanuc Controller allows Direct Input of Rotary Feeds for Each Cut
• Digressive Infeed (infeed per stroke diminishing from a preset high value at beginning of cut to a preset low value)
• Adjustable Cutter Positioning at Top of Stroke
• Crowning and Taper Capability via Back Off Cam
• Complete "Hydrostroke" Hydraulic Power Unit
• Constant Pressurized Lubrication to All Working Elements
• Mechanical Straight Spur Guide for Cutter Spindle (interchangeable with hydrostatic guides without changing or adding any hydraulic equipment)
• Cutter Spindle Adaptor
• Guards, Covers, Misc. Wrenches, Spanners, Operator Tools
• Operator's Manual, Parts List, Wiring & Hydraulic Diagrams
• The Machine is Wired for 480V 3-phase
• Fully Air Condition Electrical Cabinet

Programmed Features

• CNC Controller has Macro Screens for "Operator friendly" Question and Answer Setups (NO PROGRAMMING NEEDED)
• One to four Cut Selected by CNC Controller
• Setups can be Stored in Nonvolatile Memory using a Setup Number between 1-9999
• Recut Mode Allows the Operator to Bring the Part into Size Without Changing the programmed parameters
• Each cut has individual parameters for:
- Depth of Cut
- Infeed Rate
- Stroking Speed
- Rotational Feed Rate
- Degree of Work Rotation

Optional Equipment

• Chip Conveyer
• Hydraulic Work Clamping
• Full safety enclosure
