The LittleMachineShop.com model 3501 CNC Milling Machine is a complete CNC solution. It's not a conversion or adaptation; this machine is designed and built by the factory as a CNC machine.

The Model 3501 now includes a one-shot lubrication system and an improved mill table that facilitates the use of flood coolant.

Up until now, hobby CNC has required that you make or buy a conversion of a manual milling machine. You had to integrate the mill, ball screws, stepper motors, drivers, power supplies, and breakout boards. Most people don't even know what those things are, much less how to integrate them into a working CNC machine.

The LittleMachineShop.com model 3501 is the perfect mill for the bench top machinist who wants to create parts and not just build a CNC machine. The power supplies and controllers are built into the mill. No extra cabinets, cables, or connectors are required. The model 3501 CNC milling machine even includes a 4th axis driver so you can add a 4th axis rotary table by simply plugging it in.

With powerful NEMA 23 hybrid stepper motors connected by zero backlash jaw couplings to precision-ground ball screws, the model 3501 can achieve positioning accuracy to 0.0005". Not many hobby-grade machines can make a claim like that. It will machine at up to 20 inches per minute and rapid traverse at up to 80 inches per minute.

A 2/3 horsepower closed loop brushless DC spindle motor and synchronized belt drive takes the spindle from 100 to 7000 rpm under full CNC control. A one-shot oiler with flexible shielded lube distribution tubing takes care of daily lubrication with a single press of a lever.

With a work envelope of 10.2" (X-axis) x 4.3" (Y-axis) x 7.1" (Z-axis) the model 3501 has large capabilities in a small machine. And at 190 pounds, you know it is not a toy. The mill table is 15" x 5.38", giving you plenty of room to mount your work and fixtures.

A software controlled receptacle on the back of the machine provides CNC control of an optional mist or flood coolant system.

And we haven’t forgotten your safety. The model 3501 carries the CE marking, the European counterpart to UL listing. A safety E-stop button right on the front and the interlocked spindle shield shut down the mill instantly.

This is the machine only; a computer and tooling must be purchased separately.

The LittleMachineShop.com model 3501 CNC Milling Machine is a version of the SIEG KX1.

*NOTE* We ship machines only to the US and Canada.

You need a computer to drive the CNC milling machine. You can get the model 4244 Machine Controller, or you can use your own computer. The computer must meet these minimum requirements:

  • 2-GHz CPU
  • 1 GB memory
  • 20-GB hard drive
  • Windows XP, 7, 8, or 10
  • 32-MB video card
  • USB port (to connect to mill)
  • Front USB port (for USB flash drives for moving files)
  • DVD/CD-ROM drive 

We do not support the use of notebook computers because the power-saving features affect the functioning of Mach3.

These machines ship by freight truck because they are simply too heavy and bulky for UPS Parcel Service. If your location will be difficult for larger truck/Semi-trailer, please let us know.

We normally ship truck orders a day or two after we receive the order. For local orders transportation usually takes no more than a day or two. For orders going across county or over water the transportation time can be up to a week or longer.

We add the following shipping cost to your order total:

We ship machines only to the US and Canada.

Additional Notes

  • Contact and delivery. Ensure you choose the correct type of delivery, have a dedicated contact person/number, and are ready on day of delivery. Freight companies charge an additional fee if delivery exceeds 30 minutes.
     
  • Only one shipping charge for entire pallet (up to 700 pounds total). The shipping charges shown above cover the cost of shipping the machine and anything else that you purchase with it, including a second machine, stand, tooling, and accessories.
     
  • A "commercial address" has a sign with company name, a public entrance and posted hours of operation. If you are running a business at your residence without a public entrance and posted company name and hours of operation it is considered a residence and a not commercial address.
     
  • A "limited access" designation is required for "Secured Locations" (schools, colleges, universities, university hospitals, military bases, government facilities, etc). Please provide accurate details on delivery in special instructions.
     
  • "Terminal Pickup" allows for pickup at local terminal. If there is not a terminal within 50 miles (or 1 hour), we will confirm with you that you still want Terminal Pickup. Terminals tend to be near highways (usually miltiple intersecting) and industrial centers. Only certain terminals allow pick-up.
     
  • "Residential delivery" does not include moving machine into home/garage/workshop or any setup. Delivery is to start of driveway on the street that the delivery truck can access. (See inside delivery below.)

 

For delivery to Alaska, Hawaii, or Puerto Rico

We will check with several trucking companies to get the best price and then call for your approval before we ship.

 

Canadian Shipments

Truck Freight shipping to Canada involves 3 distinct charges in addition to the product costs. (All amounts are in US Dollars, see the current mid-market exchange rate.)

  1. Canadian Provincial Taxes (GST, PST, HST) depending on which province the shipment is going to. This will be 5% - 15% added to total sales amount depending on province (Canadian Sales Tax).
     
  2. Hemisphere Customs Brokerage which handles all customs clearance requirements. This is a flat fee of $108 on any shipment.
     
  3. Truck Freight from Southern California to destination in Canada. This is generally $300-$500 for residential liftgate delivery and appointment for single machine + tooling orders. Delivery to a terminal for pick-up or a commercial location with loading capabilities can reduce this cost substantially.
