The EMAG UG Series lineup: UG 400, UG 630, UG 1000 and UG 1500 cover grinding lengths from 400 to 1,500 mm.
Work area of the EMAG UG Series. The combination of swiveling B-axis and direct-drive spindles enables internal and external grinding.
Precision internal grinding on the EMAG UG Series: Direct-driven spindles and rigid machine kinematics help ensure high dimensional accuracy and enhanced surface quality in the micrometer range.
Compact workhead with precision tapered roller bearings for roundness accuracies of up to 0.5 µm. The swivel range of 0 to +30° enables flexible machining strategies.
The tailstock has a precision bearing quill with fine adjustment and sensory equipment for monitoring the workpiece position as well as a hydraulic reset.
EMAG LLC has announced the availability of the UG Series universal cylindrical grinding machines for the U.S. and Canadian markets. The series is designed for manufacturers who require flexible, high-precision grinding across internal, external, and out-of-round applications without investing in separate dedicated machine platforms.
The UG Series includes four models-UG 400, UG 630, UG 1000, and UG 1500-with grinding lengths corresponding to 400, 630, 1,000, and 1,500 mm. The series features multiple grinding wheel configurations tailored to job shops, precision component manufacturers, toolmakers, and production facilities serving the automotive, aerospace, and industrial supply chains.
The grinding head on each UG Series machine is equipped with direct-drive motorized spindles rated at up to 11 kW. The elimination of belt drive removes a primary source of vibration and mechanical power loss in conventional cylindrical grinding systems, the company reported. Peripheral grinding wheel speed reaches 50 meters per second.
An automatically swiveling B-axis enables infinitely variable positioning between -15° and +225°, with 0.0001° resolution and ±2 arc seconds positioning repeatability. Swivel time for a 180° repositioning is 8 seconds across all four models.
Precision tapered roller bearings in the workhead provide the rigidity required to achieve concentricity accuracy of 0.5 micrometers on the test workpiece. The workpiece spindle uses direct drive with stepless speed control from 30 to 800 RPM. A swivel range from 0° to +30° supports cone grinding strategies. High-frequency internal grinding spindles cover a speed range of 20,000 to 125,000 RPM with oil-air lubrication on the UG 400, UG 630 and UG 1000.
An optional C-axis workpiece spindle enables out-of-round and thread grinding through synchronized motion between workpiece rotation and grinding spindle feed, requiring the FANUC 31iB Plus control.
The tailstock uses a precision-mounted quill (60 mm diameter, MK4 taper; 65 mm on UG 1500) with micro taper correction of ±40 µm for concentricity under one micrometer. Manual or hydraulic actuation options are available. Three dressing configurations are supported: a repositionable table-mounted swivel arm dresser, a workpiece spindle dresser system for automated batch production cycles, and dressing tile holders for supplemental or manual dressing.
The UG Series standard control is the FANUC 0i-TF Plus with dialog-oriented HMI for simplified operation. The FANUC's global service availability is a practical advantage for U.S.-based manufacturers managing maintenance and spare parts logistics.
EMAG offers turn-key packages for the UG Series including machine, NC program, grinding tools, coolant, and workholding technology. The customer receives a production-ready solution from a single source.
EMAG LLC provides U.S. and Canadian sales, applications, engineering and service support from its Farmington Hills, MI, location.
