Introducing two new CNC Routers from Spark Robotic: the RTR-44, the RTR-84 & the RTR-51!  Known for disrupting markets by making well-built machines at affordable prices, Spark Robotic makes all its products in America and supplies them directly to the consumer.  Throughout our years providing our customers with CNC plasma tables, we were frequently asked to recommend a CNC router that was up to our standards.  We're pleased to announce that we can finally recommend our very own RTR-series CNC routers!  

At base, our RTR Routers share a proven design foundation with our light industrial XR plasma series.  However, the RTR Routers also integrate several key features that we wanted to see in a class-leading router platform.  Our goal was to design and engineer a CNC router that would work all day long with precision, speed and reliability, all without breaking the bank. The result is the RTR series of CNC routers outperform the competition while saving you $5,000 to $20,000 vs comparable routers.   

After more than a year of highly focused prototyping, research, and testing, the RTR Routers have proven accuracy in cutting wood, foam, composites, and non-ferrous metals (i.e., aluminum and brass). More info below on what the RTR Routers can do, including how they can improve your workflow and bring value to your shop. 
 
Hardware Specs:

• Modular design with a fully-welded gantry and 3 fully-welded leg sections fabricated from American-made, laser-cut steel tubing
• 60 holes for mounting a table board

• Heavy-duty, hardened, precision 23mm linear rails
• 10 oversized linear bearings
• Gear and rack drives on both the X and Y axes
• Precision mechanical gear reductions on both the X and Y axes

• High-Power Servo motors on all axes
• 2.2 kw (3HP) spindle with VFD control (110 or 220V)
• Laptop included  
• Automotive-style wiring harness

 

The Table

We thought long and hard in order to bring you a modular design that, while incredibly rigid, is still simple enough that you can assemble the base table in under 30 minutes.  We were eventually able to accomplish this via laser-cut steel tubing with oversized "tab and slot" plates welded on each end.   These plates make for large, flat mating surfaces that join together perfectly, thus allowing for a massive amount of clamping force.  The laser-cut steel tubes are then powder coated (in-house) to make sure they're perfectly aligned (and not to mention aesthetically pleasing).  Unlike many of our competitors, we use American-made steel in the structural components of our tables instead of extruded aluminum.

  

The Drive System

The RTR Routers use HG-23 linear bearings, as well as a rack-and-pinion drive with gear reductions on the X and Y motors for motion.  The Z axis uses a 16mm ball screw for maximum rigidity.  Our Z axis is reverse-mounted to keep dust and debris off the ball screw and bearings, as well as to maintain maximum rigidity near the bit--exactly where you want it.    

             

2.2kw (3HP) Spindle and VFD

The RTR Routers use an air-cooled 3 horsepower spindle controlled by a VFD (variable frequency drive) with an RPM range of 8k to 24k.  We tested air-cooled vs water-cooled and found that air-cooled heat dissipation was as good, if not better, than water-cooled at 8000+ RPM.  This allows our machines to operate without a liquid cooling system, meaning the customer does not need to worry about leaks, evaporation, maintenance, or mold growing in their spindle.  The spindle uses ER-20 to hold cutters up to 1/2" and comes with a 14-piece collet set from 1/2" all the way down to 1/16".

                        

The VFD is completely controlled by the integrated software.  Your g-code will automatically set the spindle RPM, so you won't need to turn the spindle on or off or set the RPM before each cut.

                           

Planet CNC Controller and Software 

When it came to deciding which control software was right for these machines, we tested over a dozen different software packages.  We chose Planet CNC because it supported all of the many different needs we were able to imagine while also being comprehensive, customizable and user friendly.  Planet CNC is capable of 9-axis control with 8 digital outputs and 3 PWM outputs.

                          

High-Power Servo Motors 

The accuracy and speed of high-power, closed-loop servo motors are without comparison.  We have run these machines at over 3000 in/min without losing any steps.  This combination of performance and reliability is what our customers expect from Spark Robotic.  On top of all the other design and engineering choices we made (and argued over), we're excited to be able to feature these servo motors on all of our routers while managing to keep our prices lower than the competition.
