UR18g-950 18kg Payload 950mm Reach ±0.05mm IP65 6-Axis Machine Tending Robot

UR18g-950 Compact Heavy-Duty Machine Tending Cobot

The UR18g-950 is a six-axis collaborative robot from the Universal Robots g-Series that pairs an 18 kg payload with a 950 mm reach, making it a strong fit for machine tending work where parts are heavy but the cell must stay compact. With a maximum tool center point speed of 4 m/s and a pose repeatability of ±0.05 mm (ISO 9283), this machine tending cobot keeps loading and unloading cycles fast and consistent. At only 39.2 kg, the arm is light enough to mount on benches, gantries and mobile carts, yet it still carries larger end effectors and heavier workpieces with a 350 N force capability at the tool flange.

Built on the Gen 7 platform, the UR18g-950 runs on PolyScope X software together with the CB7 Core controller, TP7 Core teach pendant and SP7 Smart Panel. Power, data and safety connectivity are brought straight to the tool flange: 24/48 V power (5 A peak, 3 A continuous), a 1 Gb Ethernet port and M8 I/O for digital, analog and RS-485 signals, so cameras, sensors and higher-power grippers connect without extra cabling. An enclosed joint design and an IP65 rating protect the arm in dusty and washdown machine tending environments, while an ISO 10218-1:2025 compliant 2PE Freedrive button and an LED light ring make teaching and status checks quick. Every joint offers a ±360° working range for flexible reach into machine tools.

Technical Parameters

Key Advantages

• Heavy-duty yet compact: an 18 kg payload in a 39.2 kg arm suits tight machine tending cells.
• Fast cycles: up to 4 m/s TCP speed cuts loading and unloading time.
• Repeatable precision: ±0.05 mm pose repeatability keeps part placement consistent.
• Rugged protection: an IP65 rating and enclosed joints resist dust and washdown.
• Simple integration: power, 1 Gb Ethernet and M8 I/O at the flange reduce cabling.
• Modern control: PolyScope X with the CB7 Core controller and SP7 Smart Panel.

Application Fields

• CNC machine tending: automatic loading and unloading of lathes, mills and machining centers
• Injection molding machine tending and part extraction
• Press tending and metal forming cells
• Pick and place of heavy parts between machines and conveyors
• Feeding deburring, inspection and cleaning stations from machine tools

Frequently Asked Questions

Q: What payload and reach does the UR18g-950 offer?
A: This machine tending cobot provides an 18 kg payload with a 950 mm reach, a balance that supports heavy end effectors and workpieces while keeping the cell compact.

Q: How fast and accurate is it?
A: The arm reaches a maximum tool center point speed of 4 m/s with ±0.05 mm pose repeatability (ISO 9283), so machine tending cycles stay fast and part placement stays consistent.

Q: Can it work in dusty or wet machine cells?
A: Yes. The UR18g-950 carries an IP65 rating and an enclosed joint design, protecting it against dust and low-pressure water jets common around machine tools and washdown areas.

Q: How is it controlled and integrated?
A: It runs on PolyScope X with the CB7 Core controller, TP7 Core teach pendant and SP7 Smart Panel. Power (24/48 V), 1 Gb Ethernet and M8 I/O at the tool flange let you connect grippers, cameras and sensors without extra cabling.

Q: How heavy is the robot and how is it mounted?
A: The robot weighs 39.2 kg with a 204 mm footprint and supports flexible mounting, so it fits standard benches, gantries and mobile machine tending stands.

For flexible machine tending, the UR18g-950 combines an 18 kg payload, a 950 mm reach, 4 m/s tool speed and ±0.05 mm repeatability in a compact 39.2 kg cobot. With IP65 protection, flange-level power and connectivity, and PolyScope X control, it is a practical machine tending robot for CNC loading, injection molding and press cells.
