BENEFITS OF THE RIGIMILL• The RigiMill was developed together with SECO tools

to be the machine that can handle the fastest chip removalrate in the world for both titanium and aluminum

• Right-sized gantry for aluminum milling and titanium milling• Generally 40% faster per part than on a 4-spindle machine• No need for operator to load part on machine table• No need for manual chip handling• Foundation cost less than 70% of multi-spindle machines• Normally 2/3 of the cost of a multi-spindle machine• Up to 970 cubic inches chip removal in aluminum• Up to 55 cubic inches chip removal in titanium• Robotic tool loading – this design maximizes spindle production time because the robot

will measure and verify the tools before they are put in the spindle• New design, competitors have design from middle of the 80´s• One specific gantry for aluminum machining and one for titanium machining• All parts FEM analyzed – Modig can show proof of machine stiffness• Outstanding performance award from Boeing – only machine tool builder outside U.S.

to receive this award• Double chip conveyor for best chip removal• Small footprint and minimized height to achieve the best stiffness

Advantages World’s first 2 in 1 machine (roughing and finishing in the same machine)Pallet system up to 600”PRICE compared to multi‐spindle machinesCustomized solution dedicated for customers partsWide variety of solutions for automationRobot tool loading with tool magazine holding up to 300 tools Flat floor designExtremely small footprintCapacity per square foot higher than competitorsGenerally 40‐50% faster than 4-spindle machines per part Less extensive and thus less expensive foundation required Good price level for smaller companiesCooperation with SECO tools for best customer solution

RIGIMILL

GENERAL TECHNICAL INFORMATION• Focus on parts that are 80” and longer, otherwise

we will have competition from commoditymachines

PROCESS• High speed 5-axis aluminum milling• Roughing in titanium or steel with up to

9,000 pounds pressure on the tool• Turn-milling

OPTIONS• Automatic pallet system for parts up to 600” long• Robotic loading and unloading for parts up to

100” long• Rotary tables• T-slot table• Rotating window fixtures• Dual zone machining areas• CNC fixtures for a variations of parts• Composite vacuum extractor• Vacuum clamping fixtures• Briquette press for chips• Ambient coolant level• 100 bar thru spindle coolant• NOTE: many features normally considered

options (such as probes) are already standard onModig machines

RIGIMILL

TECHNICAL ADVANTAGES• Double AC motors in Y and Z axis• Four AC motors in X axis for best speed and

acceleration• Five guideways in Z axis for best stiffness and

accuracy• Twelve carrier packs in Z axis for accuracy• Eight carrier packs in X for superior stability• Big AC 8 two-axis head that can handle the

cutting forces from a 170kW spindle• Mega torque motors in A and Z axis• Heidenhain rotational scales in A and Z axis• All moving parts made of cast iron for highest

stiffness, (welded steel design is very poor)• 4 rack and pinions on X-axis for zero backlash

(two is totally inadequate for a machine like this)• Double Heidenhain scales in all axis for highest

accuracy• Double ground ballscrews with internal cooling

in both Y and Z axis• Fanuc robot tool loading for minimizing

unproductive spindle time.• Robot measures tool length and diameter in

Renshaw probe instead of machine• Up to 300 tool pots• User friendly HMI operator control• All roller guideways are 65 mm for highest

stiffness (ball bearing guideways are veryinaccurate)

• Size of rail and roller pack also important• Fanuc 30i B system (the top of the range that

Fanuc can provide)• 3D crash protection software, for zero crashes

(very important) not available from Siemens• Spindle vibration monitoring• Torque detection monitoring• Spindle temperature monitoring• 27” touch screen for operator with Modig´s on HMI• Renishaw NC4 tool measuring and RPM 60 touch

probe standard• Post processor from ICAM• SECO provide cutting data and help at site for

best time and results during machining• 3R hydraulic fixing point for pallets for highest

accuracy (extremely good)• Pallets up to 16 meters in length• Automatic pallet loader with two stations for

loading parts outside working envelope• Hydraulic clamps and vacuum to hold part in

position• No cleaning the part from chips after machining.• Machine uses water curtain to clean the part

before pallet is removed• Ability to extend machine in the X-axis easily

after installation• Option to add a second gantry on the same

machine after installation

RIGIMILL

INDUSTRIES SERVED:• Aerospace• Marine• Transportation

• Heavy Industries• Automotive

EXCELS AT THESE PARTS: • Spars• Wing stringers• Landing gear• Titanium seat tracks• Wing ribs• Panels

• Titanium frames• Aluminum frames• Window frames• Railroad tracks• Rocket launcher parts• Aircraft doors
