Saturn 2 Series CNC Router – 4′ x 4′

The Saturn Series CNC Routers are the most advanced CNC router in their class today. We have created these routers to give you the performance of machines far more expensive at a price that you won’t believe.

Why Buy a Saturn Series CNC Router?

• The system wasn’t designed to be a toy. It’s an industrial machine that you can run 24/7 in a business setting if you require it.
• We believe you should be able to walk up to the machine, turn it on and make parts right away at any time; without squaring or alignment. On the first day, right after you take it out the crate. No assembly required.
• Our machines come fully assembled, tested, and cut tested.
• We believe in quality components. Bolt-together extruded aluminum frames, Leadscrews, and V-Groove linear motion systems are cheap but entry grade. With a fully welded steel tube frame, ballscrews, and 30mm profile linear motion rails, we have the best components in our class.
• Designed and Assembled in the United States. This means peace of mind knowing that technical support is available at hours that suit you and extra spare parts are readily available the next day.

Machine Frame and Gantry

• Built with an accuracy of 0.1mm. If the frame isn’t fixtured properly, you will have issues with the linear rails not being straight and parallel, which ultimately leads to binding, unreliable machine performance, and headaches for you. We do it right with the proper fixturing to ensure that each frame is straight and everything is within tolerance.
• The frame is stress relieved to ensure it’s square when it comes out of the fixture.
• All of the holes and plates on the frame are CNC milled to assure that each rail is within tolerance of each other to provide even more quality not commonly found on equally-priced equipment

The Saturn 2 Series CNC Routers feature an ALL STEEL gantry construction. We don’t just throw a lightweight piece of aluminum on the industrial frame and call it done. We pair the gantry with precision milled interface plates to give you the most rigid mounting points available. This allows you to push our machines harder and faster under load with less deflection and chattering.

Motion Components (Rack and Pinion Drives, Linear Guides, and Ballscrews)

• Our best in class Rack And Pinion drives feature:
  • The pivot point utilizes 3 different bearings for frictionless pivoting without wiggle. A needle thrust bearing keeps the plate from rubbing against the mounting plate while a high load sealed ball bearing and eccentric ball bearing keeps the whole plate from wiggling which results in excessive wear on the pinion.
  • The pinion gear is an integrated pinion and timing pulley. Inside the pinion is a sealed ball bearing which rides on a stainless steel precision machined shaft. Don’t be fooled by other systems that utilize bushings: A bearing will not wear and will always provide a smoother, more consistent motion that a bushing!
  • All black anodized parts and stainless steel hardware.
  • A 3:1 Timing belt reduction. This reduction gives the rack and pinion drive better accuracy and protects the motor from unnecessary wear.
  • A unique CAM tensioning system to apply and keep tension on the timing belt.
  • An easily adjustable spring tensioning system to always keep the pinion engaged with the rack.
• Our Ball Screws:
  • Are precision ground and come with matching recirculating ball nuts.
  • Ride on precision bearing blocks and are secured in place with needle thrust washer sets which eliminate backlash.
  • The 1/2″ ballscrew can drive even the heaviest spindle with ease.
