MR-1 Accuracy

MR-1 is packed with the high quality components that are needed to produce high quality parts. The precision grade linear guideways and ball screws work together to ensure that the cutting tool is exactly where it needs to be. The incredible rigidity of the machine structure makes sure that the tool remains on path with little deflection, during both heavy cuts and light finishing passes.

The machine boasts XYZ straightness error of less than 0.00015 per inch and positional repeatability of less than 0.0005. Every spindle is precision ground in house to less than 0.0003” runout. MR-1 is the right choice for when thousandths matter.

MR-1 RIGIDITY

Boasting spindle deflections less than 40 millionths per pound of cutting force, MR-1 is more rigid than any other machine in its class. This stiffness is what allows MR-1 to cut nearly any material between plastic and stainless steel. We believe CNC machines should be made out of steel and iron, not aluminum. That's why the entire structure of the machine is made out of thick steel plate while the carriages are made out of heavy duty cast iron for incredible stiffness an vibration damping. Tipping the scales at over 700 pounds, MR-1 is a real machine that's ready for hard work.

Drilling

With over 3 lb-ft of spindle torque and 160 pounds of Z axis thrust force, MR-1 can drill large holes with ease in a wide range of materials. MR-1 has up to 9” of clearance between the spindle nose and table meaning that jobber length drills can be used with plenty of room to spare.

Slotting

Full width slot milling is a toolpath that most machinists try to avoid, but sometimes there is no other option. Thanks to the rigidity of MR-1, full width slot milling is not an issue, even in steel.

Watch Full Slotting
Boring

Boring is the process of enlarging an existing hole to improve its size, form, and location accuracy. When a particular project requires tenths level accuracy, boring is the natural option. Success in boring requires rigidity, very low spindle runout, and high spindle torque at low RPM. Because MR-1 has all of this, boring is never a problem.

Facing

While it can be done with an end mill, facing is usually accomplished with a specialized cutting tool such as a fly cutter or a facing mill. It is typically a finishing operation used to produce flat, mirror-like surface finishes. Running large diameter cutters like facemills takes plenty of horsepower, and MR-1 has plenty to give.

3D Surfacing

We all know that 3D printing is great. But if you want to make more than one sample, 3D printing makes little sense when time is money. If you want to make a lot of plastic parts quickly, you need to be looking at plastic casting or injection molding. And to make molds? You guessed it, 3D surfacing is needed. It involves the use of a ball end mill to produce accurate and smooth 3d surfaces.

Corner Finishing

The difference between a good looking part and a great looking part is how the corners are finished. There are two main corner finishing operations; chamfering and corner rounding. Use either process with our specially ground form tools to produce the desired corner geometry to take your project to the next level.

MR-1 Power

When it comes to machining metals, torque is king. Higher torque means that larger chips can be peeled from the workpiece with each rotation of the cutting tool. More chips peeled per hour equals more money in your pocket. Thankfully the 3.4 horsepower AC spindle motor provides incredible torque throughout the entire 0-8000 RPM range. MR-1 has the power and rigidity to run large diameter cutters such as facemills, fly cutters, boring bars, and drills up to ½”.

The supercharged spindle is useless unless the motion system has the ability to push it around forcefully. That’s why the linear drives can exert over 135 pounds of cutting force at 100 inches per minute in any direction.

MR-1 FAQ

I want an MR-1 Gantry Mill but I don't have any CNC machining experience. Is it still a good choice for me?

We think MR-1 is the best choice for CNC machining education. We are confident that anyone that’s willing to put in the time can learn how to operate MR-1 proficiently. We understand the vast majority of our customers have zero experience with CNC machining, and that’s ok! As long as you are eager and willing to learn, our video tutorials will provide you with all of the knowledge that's required to get started.The best part about learning on MR-1 is that the skills are directly applicable to operating a full sized CNC milling machine.

Before machines begin shipping to customers in August, we will be releasing a comprehensive suite of tutorial and educational videos that cover the following topics:

  1. Selecting a suitable CAD/CAM package (and why we prefer and support Autodesk Fusion 360)
  2. Drawing parts in Fusion 360 for CNC milling
  3. Programming milling toolpaths in Fusion 360
  4. Post Processing in Fusion 360
  5. How to use CutControl for running MR-1
  6. Loading and running your first G code program on MR-1 in CutControl
  7. Setting part offsets and tool offsets
  8. Workholding theory
  9. Cutting tool selection
Can I finance the purchase of MR-1?

Yes, we are partnered with Affirm who takes care of all of the financing needs of our customers. While you will need to provide the $500 deposit via credit card to initially reserve a machine, financing for the balance can be established via Affirm right before your machine ships.

How does MR-1 ship and what does it cost?

MR-1 ships exclusively via freight. Approximate dimensions of the shipping crate are 48”x48”x 40”. Depending on options and accessories, the crate will weigh between 500 and 700 pounds. All MR-1 machines will ship out of our Conroe, Texas facility.

Depending on location, shipping will cost approximately $300-600. Additional fees will be charged if liftgate service is required. Actual freight charges will be calculated prior to shipping to your specific address.

All add ons and accessories ship for free if purchased at the same time as the machine.

Can I pick up my machine in person to avoid shipping costs?

Yes- as long as a suitable vehicle is used such as a pickup truck or a trailer with at least 48” of bed width you are able to pick up your order from our Conroe, Texas warehouse.. We will use our forklift to load the crate, but you are responsible for strapping. You must make an appointment for pickup by sending an email to support@langmuirsystems.comonce your machine is prepared and your balance is paid.

Is Lift Gate service available upon delivery?

Yes. MR-1 and all the associated accessories ship via freight to both residential and commercial addresses. A lift gate option is available for those that do not have a load dock to unload the crate from the delivery truck. When your order is ready to ship, you will receive an invoice email to complete the balance payment including shipping. Here you will be able to select the Lift Gate service option for your delivery. Note: a small fee will apply for Lift Gate service.

Do you ship MR-1 internationally?

MR-1 currently ships to the United States, Canada, and Mexico. International buyers are responsible for paying all duty fees in addition to the extra freight charges.

Are accessories and options more affordable if purchased at the same time as the machine?

All options and accessories take advantage of free shipping if purchased together with the machine. In addition, the freight cost is the same whether you order the base machine or all of our options so it is advantageous to include these times during your initial purchase.

Some items such as the machine enclosure are very expensive to ship if purchased separately at a later date. We highly recommend all customers do their best to order options and accessories with the machine to save on shipping.

How long does it take to assemble the machine?

Assembly time varies with skill level and selected options and accessories. We expect the average assembly to require 15-25 hours to complete.

If you prefer to receive a machine fully assembled and precision aligned by us, select the ‘Full Assembly’ option at checkout. It's a great option for those that want a turnkey system that's ready to run upon delivery; for the flat rate assembly fee we will put your machine together with all the options that were ordered.

Note that choosing the MR-1 Full Assembly Service will require custom crating and shipping leading to an increased shipping cost. We estimate the cost to be around $1,000 to most locations in the contiguous United States. The earliest these assembled machines will be available is October 2022.

Now that my machine is assembled and operable, what’s next?

Before machines begin shipping to customers in August, we will be releasing a comprehensive suite of tutorial and educational videos that cover the following topics:

  1. Selecting a suitable CAD/CAM package (and why we prefer and support Autodesk Fusion 360)
  2. Drawing parts in Fusion 360 for CNC milling
  3. Programming milling toolpaths in Fusion 360
  4. Post Processing in Fusion 360
  5. How to use CutControl for running MR-1
  6. Loading and running your first G code program on MR-1 in CutControl
  7. Setting part offsets and tool offsets
  8. Workholding theory
  9. Cutting tool selection

We understand the vast majority of our customers have zero experience with CNC machining, and that’s ok! Our video tutorials will provide you with all of the knowledge that's required to get started.

Are replacement parts available?

All machine components are offered as replaceable items for purchase if stock is available. Send us an email at support@langmuirsystems.comwith your needs and we will prepare you an invoice.

Can the Base Plates be replaced?

Yes. Much like all other parts of the machine, the baseplates are also replaceable. The baseplates secure to the embedded anchors with 56 socket head cap screws. Removing these cap screws allows the baseplates to be lifted out. The new baseplate will require skim cutting after installation.

Can the machine be run on 120V Power?

Yes. We offer a step-up transformer option for MR-1. Purchase this item If your workspace is not equipped with 240V single phase AC power for the spindle motor. This transformer steps 120V outlet power up to 240V that's needed to power the MR-1 spindle motor. Note: Peak spindle power is limited to 2.0 hp (1.5kW) on a standard 15 amp outlet.

Is the Epoxy Leveling Kit required when assembling my machine?

No. There are no issues with leaving your concrete base as poured during your machine assembly and we have run many machines this way.

While not required on your MR-1 machine, the 1 Gallon Epoxy Leveling Kit has many benefits:

  • The epoxy self leveling characteristics help to create a near perfectly flat surface that fills in any low spots in the concrete and creates a smooth to the corner drains when running flood coolant.
  • It seals the concrete from water and coolant.
  • The smooth nonporous surface is easy to clean between projects and looks visually appealing.
What future add-ons are currently in the works?

The MR-1 base platform is a jumping off point for a wide variety of upgrades and expansions. Below is a condensed list of some of the options that will be released in the future that are 100% compatible with the first generation of MR-1 machines.

  1. 4th Axis kit including rotary indexer and tailstock. This option will allow the user to flip and index their parts to any angle for machining to reduce the number of setups required. It will be robust and rigid enough to machine aluminum and steel parts. The 4th Axis head stock will include an ER32 collet chuck as standard. An optional 4 jaw chuck and trunnion table will be available as well.
  2. High Speed Machining (HSM) kit which includes faster rate ball screws and high output stepper motor drivers. This will increase the maximum cutting feed rate from 100 ipm to 200 ipm. This kit is a great option for those wanting to reduce cycle times as much as possible.
  3. Cutters of every size and type. Our goal is to have a completely stocked online store that carries every cutting tool you will ever need. This includes stub end mills, reach end mills, drills, keyway cutters, boring bars, chamfer tools, thread mills, indexable end mills, counterbores, engravers, dovetail cutters, radius tools, and more!
  4. Workholding accessories including set up blocks, table chucks, collet blocks, right angle blocks, part stops, risers, quick change pallets, vacuum chucks, edge clamps, etc.
