Haas Automation’s GR Series Gantry Routers Include Chip Guards

Haas Automation, Inc.’s range of GR CNC gantry routers are now fitted with chip guards as standard, further increasing the safety and cleanliness of the machines.

 The Haas Automation design team has created an innovative enclosure based on full-perimeter light curtains for these very successful, gantry-style machines. Designed to keep operators and moving components apart, the concept for the travelling guard is simple: chips and coolant inside, people outside! From a safety and cleanliness perspective this clearly offers great advantages to customers. All Haas GR models sold after January 1st 2014 accommodate the new chip guard as standard, with the first enhanced GR machines shipping in March 2014. 

Featuring a powerful 40-taper milling head, GR routers are available in two model configurations: the GR-510 and the GR-712. While the former offers travel in the X, Y and Z axes of 3073 x 1549 x 279 mm respectively, the latter offers customers longer X and Y travels of 3683 x 2159 mm, and the same 279 mm Z-axis. 

Each Haas GR gantry router has a 10,000rpm, 11.2 kW vector drive spindle that provides the power to cut a wide range of different metals, and the speed to cut various plastics and additional light materials. Long extrusions and large sheets of material can be processed with ease. 

The rigid steel construction of GR machines provides a stable cutting platform, while a 25 mm thick aluminium table is offered as standard. Fitted with a direct speed belt drive, the routers are capable of generating 23 Nm of torque at 4600 rpm, along with 20.3 m/min cutting feed rates. Also featured are a 10-pocket automatic tool changer (ATC), memory lock key-switch, 15" colour LCD monitor and USB port. Standard G-code programming is facilitated through the user-friendly, full-function Haas CNC control. 

Available options include a high torque 5000 rpm spindle; extended Z-axis clearance/travel; high speed machining with look-ahead capability; rigid tapping; 20-pocket ATC; Haas Intuitive Programming System; coolant system with 360-litre tank; remote jog handle; user-definable macros; and an Ethernet interface.
