JUCENTRIC

Product catalog summary

Overview: The JUCENTRIC 500 is a center-type cylindrical grinding machine known for its short cycle times and high accuracy. It is designed to grind shafts and pipes with minimal deflection, ensuring precision and efficiency.

Grinding Process: The workpiece is clamped between centers, and grinding is performed while clamped. The CNC-controlled support rail, regulating wheel, and grinding wheel are adjusted until the desired dimension is achieved. This process is patent pending and involves driving via a driver on the C-axis of the workhead. After grinding, the gap opens for workpiece removal.

Technical Specifications:

Workpiece Diameter: 15 – 60 mm
Workpiece Length: 280 – 500 mm
Corundum Grinding Wheel Speed: 63 m/sec
CBN Grinding Wheel Speed: 120 m/sec
Spindle Drive Power: 55 kW
Regulating Wheel Dimensions: 350 x 500 x 203 mm
Spindle Drive Regulating Wheel Power: 11.5 kW
Machine Dimensions (W x D x H): 4,465 x 2,770 x 2,340 mm
Weight: 18,000 kg

Key Features:

Maintains relation to centerline with clamping set-up between centers.
High dimensional accuracy due to support by regulating wheel and support rail with patented CNC height adjustment.
Shortest cycle times through simultaneous grinding of all diameters.
Minimized undulations with grinding wheel balancing on two planes.
Extremely low running noise due to grinding spindle with direct drive.

Additional Information: The machine is perfectly supported and designed to accommodate technological progress, with the manufacturer reserving the right to make changes.

CENTER-TYPE CYLINDRICAL GRINDING

Open the catalog to page 1

PERFECTLY SUPPORTED GRINDING WITHOUT DEFLECTION The JUCENTRIC 500 is characterized by extremely short cycle times and outstanding accuracy. The clamping set-up between centers retains the relation to the centerline when grinding shafts and pipes. At the same time, the support rail and regulating wheel guarantee perfect support. GRINDING PROCESS The workpiece is positioned and clamped between centers. Grinding is carried out while clamped; the CNC-controlled support rail, the regulating wheel and the grinding wheel are evenly readjusted until the finished dimension is reached. This unique, ingenious...
