WT-external-grinding-machine-DANOBAT

Product catalog summary

Overview
The WT range of medium and heavy-duty grinding machines features a cross-slide configuration to optimize the machine footprint. It is designed to handle components weighing up to 8 tons and measuring up to 10,000 mm in length. An optional gap bed is available for large diameter components.

Construction and Configuration
The machine base and sub-assemblies are constructed from stabilized perlitic cast iron. The WT grinders offer various wheelhead configurations, including straight, angular, and 'B'-axis driven by an integrated torque motor. Wheels can be mounted on hydrostatic bearing spindles, roller bearings, or electric spindles designed by DANOBAT. Depending on the application, corundum, CBN, or diamond wheels can be used.

Performance Enhancements
To maximize performance, WT machines can be equipped with in-process measuring systems, automatic wheel balancing with gap and crash detection, axial positioning systems, and taper correction systems.

Technical Description

Rigidity, Stability & Precision: Features include FEM optimized frame structure, stress relief tests, stabilized one-piece perlitic cast iron, coolant circulation, and wide, strong hand-scraped guides.
Flexibility and Versatility: Modular design, high-tech grinding processes for complex materials, and a wide range of wheelhead configurations.
User-Oriented Design: Ergonomic design, clean working area, user-friendly grinding software, and compact machine footprint.

Optional Equipment
Options include automatic wheel balancing systems, new generation grinding software, touch systems for axial location and measuring, DANOBAT MDM-absolute measuring systems, and various contact or non-contact measuring devices.

UNIVERSAL HEAVY-DUTY GRINDING WITH CROSS-SLIDE CONFIGURATION WT UNIVERSAL HEAVY-DUTY GRINDING WITH CROSS-SLIDE CONFIGURATION The medium and heavy duty WT grinding machine range has a cross slide coniguration to optimise the machine foot print. Machine main groups like wheelhead, workhead and tailstock are designed to grind components weighing up to 8 ton and 10000 mm length. Gap bed option is available for large diameter swing components. The machine base and sub-assemblies are made of stabilized perlitic cast iron. WT grinders can be equipped with a wide range of wheelhead conigurations: straight, angular and “B”axis which is driven by an integrated torque motor. Wheels are assembled on hydrostatic bearing spindles, roller bearing or on DANOBAT designed electric-spindles. Depending on the application, corundum, CBN or diamond wheels can be utilised. In order to obtain the maximum machine performance WT machines can be equiped with in-process measuring systems, automatic wheel balancing incorporating gap and crash, axial positioning system and taper correction system, etc
