The MR-1 Gantry Mill stands alone as the only machine in its price class that is capable of productively machining aluminum, steel, titanium, and stainless steel. MR-1 is not a toy; it is a machine that you can rely on to make real metal parts that require excellent finishes, precision, and accuracy.

Let's start with the Hardware:

MR-1’s table is a nearly ¾” thick plate of 6061-T6 aluminum that is drilled and tapped for ¼-20 tooling holes in a 2”x2” grid pattern making workholding a breeze. The table is rigidly encased in 300 pounds of high strength interlocking concrete to promote excellent rigidity and stability. The base is designed to be skim cut flat by the user to produce a laser flat surface that is exactly parallel to the XY plane of the machine.

Four steel legs support the machine making it a freestanding unit. This means you don’t need to buy or build a workbench like most hobby machines. The legs come pre-drilled for attaching accessories such as leveling feet, computer stand, or touch screen controller (all available for purchase).

Also encased in the concrete base structure are the steel Y axis rail supports. To these mount the 1” thick steel Y axis rails containing the 20mm linear guideways. The direct connection to the concrete base structure keeps deflections to a bare minimum while providing a direct path for vibration damping.

Riding on the Y axis rails is the beefy X Axis gantry. There are no aluminum extrusions found here. The heavy duty gantry is constructed from 5/16” steel plate all the way around for maximum bending and torsional stiffness. It is machined and 100% inspected to exacting standards to hold a pair of 20mm linear guideways right where they need to be for supreme accuracy.

Keeping with the ‘aluminum has no place on the frame of a CNC mill’ theme, the X axis and Y axis carriages are made out of gray cast iron. The working surfaces are precision machined and 100% inspected to ensure that our quality requirements are met. Cast iron was chosen for its superior stiffness and vibration damping.

Machine travels are 23.0” (X), 21.0” (Y) and 6.1” (Z). An additional 2” of static Z-axis travel is available by adjusting the vertical spindle mounting position.

The Spindle:

The spindle motor is the heart of the machine, and we did not skimp here. The 220 V AC servo motor packs a whopping 3.4 horsepower and nearly constant torque from 0 to 4000 RPM. The 1:2 overdrive transmission allows the user to pick any cutting speed in software up to 8000 RPM. The built-in encoder means that the motor can maintain its programmed speed even under heavy loads.

When it comes to machining metals, torque is king and this beast of a spindle motor has plenty to give. Trim routers and low torque VFD driven spindle motors don’t belong on a machine designed for milling metal, especially steel. Our Spindle can run fly cutters, drills, boring heads, and large end mills. All without violating the SFM specs provided by the cutting tool manufacturers for carbide and high speed steel.

The spindle itself is custom made from high grade alloy steel and through-hardened for wear resistance. The ISO-ER20 taper of each is precision ground in-house to ensure runout is less than 0.0003”.

Don't have 220V power in your shop? Consider picking up a transformer to run our spindle motor on any ordinary 110V outlet.

The Electronics:

Pushing the spindle around are precision 1205 ball screws driven by NEMA 23 waterproof stepper motors. Each axis can exert over 135 pounds of cutting force that is reacted by 1” thick steel bearing mounts. This is sufficient for removing up to 30 pounds of steel per hour with the correct roughing tool and tool path setup. Maximum travel speeds of 100 inches per minute (IPM) ensure your projects get completed fast.

MR-1 not only comes standard with limit switches, it comes with two on the Y axis. This gives the machine automatic squaring capability of the gantry. Each time the user homes the machine in software, it will fine tune the alignment of the X axis to the Y axis on the fly to ensure squareness is achieved.

At the heart of the electronics is our proprietary motion control board with high speed USB communication. Based on the successful control boards from our CNC Plasma line of machines, this robust and battle tested system allows the user to stream millions of lines of code without skipping a beat.

The electronics box also includes ports to connect the Automatic Tool Setter and Touch Probe. The combination of these two devices allow the user to establish massively increased workflows by setting part locations and tool offsets automatically at the push of a button.

The Software:

Included with every machine is the CutControl software package that runs on both Windows and MAC OS. It takes the engine from our widely successful FireControl software and pairs it with the features required to blast through milling projects on MR-1, including a 3D visualizer. Control the machine at your fingertips including Spindle Control and RPM setting, Flood Coolant, Program Speed Overrides, Automatic Tool Setting, Touch Probing Routines, Milling Canned Cycles and many others. We are constantly adding new features and optimizations to improve the user experience of our software packages and this is no different with CutControl.

The Touchscreen is mounted on a swivel bracket so that the perfect viewing angle can be achieved for both seated and standing users.

The Control PC is specifically configured for use on MR-1 and comes pre-installed with Windows 10. It attaches directly to the back of the touchscreen in order to keep things tidy and the cabling short and out of the way. Programs can be loaded either via USB stick, or by simply taking advantage of the controllers WiFi to send and receive programs wirelessly from your design PC.

Setting work offsets, changing tools, and inspecting your projects requires the user to get up close and personal. Thanks to its 20’ connectivity radius, the wireless control pendant lets you control nearly every function of CutControl without having to physically be at the touchscreen.

Product Link 

Includes:

• High flow submersible coolant pump
• 15 gallon coolant tank with steel lid
• Feed hose, loc line nozzle, and associated mounting brackets
• 2 side drains, stainless wire mesh drain filters, and drain hoses
• All associated hardware and fittings

When it comes to machining materials like aluminum and stainless steel, flood coolant is a must have. Some will argue that mist coolant is an acceptable alternative, but research across the board shows that tool life, accuracy, and surface finish all benefit greatly from the use of flood coolant.

At the heart of the system is the powerful submersible pump that rests directly inside of the 15 gallon polymer coolant tank. With the ability to safely pump solids up to ⅛” in diameter, small debris and chips that get past the drain filters will cause no harm to the pump. The pump offers massive pressure and flow to blast away chips and keep your cutters completely flooded in coolant via the included loc-line nozzle with on/off valve.

This kit also includes all of the drain plumbing that is cast directly into the concrete base structure during assembly, much like the plumbing in slab foundation homes. Drains on either side of the base plate are protected by fine mesh stainless steel filters to ensure the drains will never clog with swarf.

We recommend picking up these other options with the flood coolant system:

1. 1 Gallon Synthetic Multipurpose Cutting Coolant
2. Leveling Feet Kit - Leveling the machine ensures that the coolant drain flow is equalized between the two drains
3. Machine Enclosure

Note: If you're not purchasing the flood coolant kit, but think that may change in the future, we highly encourage you to purchase and install the flood coolant drain kit so that the drains can be installed at the time of assembly:

Product Link 

Includes:

• Swivel type Steel leveling foot – qty. 4
• Aluminum leveling foot mount – qty. 4
• Mounting screws

The leveling feet attach to each leg on MR-1 and can be individually adjusted to level the machine at all four corners. This is especially important if you plan on running our Flood Coolant Kit to ensure that the machine is level to equalize flow to all four drains.

If you are planning to epoxy coat your base, we strongly recommend purchasing this kit. The self-leveling characteristics of the epoxy require the surface being coated to be level in order to work properly.

If you plan to move MR-1, we recommend purchasing this kit so that the machine can be releveled after moving.

Includes:

• Redesigned Electronic Touch Probe with increased accuracy, repeatability, and reliability
• Ruby tipped carbide stylus, 1.25” long
• Cable to plug into CNC Electronics Enclosure

New and Improved! The Langmuir Systems V2 Touch Probe has been extensively redesigned to include a 3 pin kinematic mechanism that provides the following benefits:

1. Ability to resolve position to less than .0005” accuracy
2. Elimination of mechanical play present in some V1 probes
3. Increased ease of disassembly and reassembly without compromising accuracy

With our custom designed touch probe you can quickly and automatically set work offsets using CutControl’s integrated probing canned cycles. Within less than a thousandth of an inch the probe will find the corner of a block, the center of a bore, the center of a slot, and much more. The probe can also serve as a useful inspection or digitizing tool for your projects.

The replaceable probe stylus is constructed of either carbide or ceramic for stiffness and is ruby tipped for wear resistance. Adjustment screws allow the tip to be adjusted to zero runout. The shank can be gripped using a standard ⅜” ER20 collet.

The probe contains four indicator lights letting the user know when the probe tip has made contact with the surface of the part.

Using the touch probe in conjunction with our tool setter will make the entire process of setting part offsets and tool offsets fully automated. Want both? Consider purchasing our bundle at a discounted price.

Product Link 

Includes:

• Electronic Tool Setter
• Cable to plug into CNC Electronics Enclosure
• Mounting hardware

No tool changer, no problem. With the Automatic Tool Setter make accurate tool changes at a productive pace on MR-1.

Before any machining can take place, CutControl must know where the tip of the tool is in relation to the part that is to be machined. While the option exists to manually touch the tip of the tool to the surface of the part, doing so is tedious and could cause damage to the tool or part if care is not used. When machining a part that requires many tool changes, the time used for manually touching off tools can quickly add up.

Using the Langmuir Systems Tool Setter not only saves time, but it also improves accuracy and repeatability. Thanks to its plug-and-play integration into CutControl, tool height is quickly and accurately sensed at the press of a single button. When machining complicated projects with multiple tools, the time saved can be substantial.

The waterproof design ensures that the Tool Setter can be safely used with the flood coolant system. The base includes mounting holes that match the tooling hole spacing on the baseplate so that it can be mounted anywhere that’s convenient and out of the way. Four adjustment screws allow the surface of the platen to be perfectly leveled to the XY plane of the machine. The Toolsetter contains four indicator lights letting the user know when the tool has made contact with the surface of the platen.

Using the Tool Setter in conjunction with our Touch Probe will make the entire process of setting part offsets and tool offsets fully automated. Want both? Consider purchasing our bundle at a discounted price.

Product Link

Product Link 

Includes:

• Tramming Tool
• Compatible with the MR-1 Dial Test Indicator (Sold Separately)

This device allows the operator to directly measure spindle tram error so that the spindle can be shimmed/adjusted to eliminate the error.

Achieving exceptional surface finish with minimal steps between passes requires a spindle that has minimal tram error. Tram error is the measure of perpendicularity between the axis of the spindle and the XY plane of the machine. A spindle with too much tram error presents the cutting tool at an angle to the workpiece which has the tendency to create a stepped surface finish. The effect is magnified when using larger tools such as a fly cutter.

This tool sweeps an 8” diameter and should be used directly on the baseplate after it has been faced.
