ExternalUVA LIDKÖPING is Sweden’s largest machine tool manufacturer. We specialise in the manufacture of precision grinding systems.
Our goal is to give you accuracy, efficiency and reliability through our products, our process knowledge and development, customer support and service. Through close cooperation with end-users, we ensure a correct and profitable solution for you, the customer.
The machine concept is based on the earlier generations of Lidkoping machines delivered in thousands all over the world. While this concept originally was made for the small range bearing sizes, the all new High Volume™ machines take this well proven concept also into the medium and large segment of bearings and other work pieces.
The direct driven grinding wheel spindle carries a diameter 610 mm grinding wheel, up to 120 mm wide, with or without automatic balancing built-in to the grinding wheel flange. With the grinding wheel dresser fixed onto the machine base, during the grinding cycle, the grinding wheel spindle is moving between three positions; grinding, loading and dressing.
Machine Concept
Slide System
Hydrostatic length slide, driven by linear motor. Optional dovetail type cross-slide, servo motor and ball screw operated.
Dressing
Fast full profile diamond roller plunge dresser for the highest productivity needs or CNC-dresser for more flexibility.
Grinding Spindles
A direct driven grinding spindle enabling grinding wheel peripheral surface speeds up to 60 m/s. As option the grinding wheel is automatically balanced.
Work Head Spindle
The work head spindles is direct driven and supported by high precision angular contact ball bearings. The work head can be swiveled -0.5 to 30 degrees.
Gauging Method
In-process 1-finger electronic gauging head.
Machine Control
Graphical user interface provides user-friendly controls. Control System, Siemens Sinumerik One.
As an option the machine can be equipped with Acoustic Emission analysis for process supervision and gap-elimination.
Chucking Principle
Shoe centerless or centric.
Handling
The work pieces are loaded through in- and outlet chutes.
Grinding Operations
External grinding of bearing rings, rollers or other applications.
