ZEUS-86

The ZEUS-86’s high-rigidity, bridge-type monoblock structure allows high-speed, high-precision machining while the minimized distance between the Z-axis guideways and spindle center provides greater stability. The high-rigidity bed with ideal rib distribution guarantees static positioning accuracy of ±0.000080″ and ±0.000030″ repeatability.

The ZEUS-86 is capable of a wide spindle speed range (200 – 25,000 RPM) using an oil-mist lubricated spindle and a 20-HP AC spindle motor. High-speed direct hard milling is possible via dry or semi-dry oil-mist systems. New HSK-E50 holder achieves six times higher clamping force than a regular BT shank while Dual Balance Cylinders reduce the load for the Z-axis ball screw and servo motor.

The ZEUS-86 is a unique member of the Roku machine family as it uses a Twin Drive System for the Y-axis.  This is a twin direct drive motor/ball screw system that is designed to move the large table and workpiece weight and still maintain its high degree of accuracy.

The ZEUS-86 features a Fanuc 31i-B5 Super High-Speed Processor and Al Contour Control II – A “NANO CNC System” with Intelligent Velocity Control, NANO Interpolation, and NANO Smoothing

OVERVIEW

The ZEUS-86 is a special member of the Roku family due to its size and the 1,763 lb. workpiece load it can handle.  To achieve the High Precision High Speed macro fine machining technology the ZEUS-86 has been designed using a high rigidity base casting, a column and cross rail forming a single mono-block structure with a special rib structure to suppress thermal deformation, a Twin Drive Y-axis ball screw system moving the table and workpiece weight, and a dual Z-axis balance cylinder that holds the weight of the spindle thus providing smooth, precise and stable movement.  The entire machine is designed using HIS (Heat Isolation System) that combines heat discharge fans on all axes and dual chiller systems to cool the spindle and machining coolant.  Thermal Growth Control is held to ±0.1°C using this combined system.
