The introduction of the MRC controller in 1994 allowed Motoman to introduce the revolutionary SK line of six-axis industrial robots. With the new ability to control up to 21 axes and synchronize two robots, the SK line became popular in arc welding workcells. The potential workload was increased by 300%.
A new line of AC servo motors, the Sigma series, gave Motoman robots maximum power for increased productivity. Sigma motors offered 33% less weight and size without compromising power, allowing the SK robots to offer the slimmest profile available. Other advantages included higher axis speeds and an increased work envelope. Late model SK robots used the XRC control system for new programming features.
Refurbished used robots made sense for this small business for a number of reasons. The Motoman K6 and OTC/Miller MR-V6 from RobotWorx gave Blue Chip even more flexibility. Now they have the luxury to be picky about the projects they accept. They can be more specific when they make offers.
Blue Chip is outfitted for multiple applications, from machining and fabricating to welding and painting. The company typically works with metals - handling U.S. Military Surplus projects as well as parts for both commercial and privately-owned companies. Tatman's wife, Tammy owns the company, which employs 47. Fittingly, a quarter of the Blue Chip workforce have served in the military.
For Blue Chip, the financial benefits of buying used robots were instantaneous. Tatman's first refurbished robot was four years old and cost just $20,000 (compared to $90,000 new). Tatman's second robot purchase less than a year later cost only $60,000 (compared to $150,000 new). Each robot paid for itself after a few months.
Despite all the advantages, when it comes down to it, Tatman admits the true reason he buys from RobotWorx is trust. Tatman and RobotWorx owner Keith Wanner started their businesses a year apart from each other - RobotWorx in 1992 and Blue Chip in 1993. "I've watched him grow and he has watched me grow," Tatman said. He appreciates the introduction to robotics he has received from Wanner. "When it comes to the down and dirty of the mechanics, there's no one better than Keith," Tatman said. "I don't think there is anyone more knowledgeable [about robots]."
The versatile M-16iB robot does it all - from assembly and dispensing to laser and water jet cutting. This hardworking 6-axis robot is known for its accuracy and flexibility. Two different versions of the popular M-16iB robot are available. The M-16iB/20 provides a 20kg payload and 1667mm reach. The long reach M-16iB/10L extends 1885mm and handles 10kg.
This thin Fanuc robot is built to fit into tight floor plans. Mount it upside down, on its side, or to the floor. Its compact design and footprint allow for installation in close proximity to parts. This flexibility also increases application speed and impacts productivity.
Thorough refurbishing methods and testing procedures have raised the bar for used robots. You could save as much as 50% for the same performance as a newer model. Plus, with integrators like RobotWorx, you don't have to worry about missing out on warranties and customer service. Explore the options available - debunk the used robot myths.
