from 800 mm to approx. 1.150 mm, starting 1.175 mm over clamping table Hydrostatic table bearing

Radial and axial hydrostatic table guide incl. oil cooling of the circuit of the workpiece carrier assembly – Increase of the table load to 80 kN Two-speed partial transmission

for the speed range of the workpiece table 0,08 – 32 rpm Hydraulic workpiece clamping device

For actuating workpiece-bound clamping devices, installed in the workpiece table. A safety system receives the clamping force for a limited time even if the hydraulic pressure fails – Clamping force max. 160.000 N Digital tension travel control for the hydraulic workpiece clamping device Flow monitor for coolant

For machines with automatic workpiece changes, a flow switch is required to ensure a corresponding minimum oil flow rate for cooling the milling process (fire hazard). Oil mist separator device

When working with oil as a process lubricant, the equipment of the machine with an internal oil mist extraction system or the connection to a central oil mist suction device for the CE conformity is mandatory. The oil mist separator device is based on electrostatic action and is integrated in the working area cover. Version with 5.000 m3/h suction power. Machine stabilization system

Oil recooling unit with preheating and various circuits including circulation lubrication / hydraulics and cooling lubricant.

Protection door

opens and closes automatically the machine door Linear measuring system X-axis

alternatively to the rotational measurement of the radial tool position HURTH MODUL-Dialog program

with plain text operator guidance in WINDOWS Execution for entering all geometric and technological parameters for the HURTH MODUL standard sub-programs. The operator guidance includes the calculation of the necessary cutting and cutting paths as well as of the tangential milling setting range and a plausibility test of the entered parameters. The parameters entered in the dialog can be stored in files for repeated processing. Parallel programming

The input dialog for a new workpiece can be made parallel to the current machining Hand control panel for essential set-up activities

especially for setting up the machine. This equipment is generally recommended for the user-friendly implementation of setup work such as scratching, inserting, tool change etc. Indexing device for form milling (single part method) Tool conditions monitoring

due to measurement and evaluation of the milling spindle motor current, basic signal required by control-integrated hardware and software of the SINUMERIK 840 D, use of the HURTH MODUL dialog program Cabinet cooling

Temperature stabilization of the control cabinet via a cooling unit instead of the filter fan Cabinet lighting Fully automatic centering of pre-toothed rotors

by recording the rotor reference position by means of the Renishaw button as well as corresponding correction of the operating dialog for storing rotor-specific parameters Milling spindle positioning

for milling position-oriented gears (Use of the HURTH MODUL dialogue program required)
