USED SUNNEN VSS-64-E-S18

Sunnen VSS-64-E-S18 High-Production Multi Spindle Single Stroke (Single Pass) CNC Honing Machine

The model breakdown indicates a VSS Series machine with 4 spindles and 6 stations, equipped with electronic/servo-controlled mechanics and integrated tooling/abrasive packages.

Core Machine Capabilities

The VSS Single Stroke system relies on a sequential pass mechanism where the workpiece moves through a series of pre-set diamond-plated tools to progressively expand and finish the bore to ultra-precise tolerances:

Spindle Configuration: 4 active spindles paired with a 6-station rotary indexing table.
Spindle Power: Typically powered by a high-torque 7.5 kW (10 Hp) motor.
Control System:
Complete CNC multi-axis automation with digital servo-motor/ballscrew feed control for rapid vertical column positioning and table indexing.
Diameter Capacity: Standard single-stroke platforms handle bore diameter applications ranging from 3.9 to 50 mm (0.149 to 2.0 inches), contingent on the specific modular tooling block used.Carriage Feed Speed: Up to 105 mm/sec (250 inches per minute) with a maximum carriage stroke travel of 724 mm (28.5 inches).
