Product catalog summary

Overview: The JUPITER series centerless grinding machines by JUNKER offer significant production advantages, including CNC height adjustment for quick setup, automatic grinding gap geometry adjustment, and an inclined bed for precision. These machines use corundum, CBN, or diamond abrasives depending on the application.

Grinding Processes:

Throughfeed Grinding: A highly productive method where workpieces pass continuously through the machine, with the grinding wheel having zones for roughing, finishing, and ultra-fine grinding.
Plunge-Cut Grinding: Used for workpieces with offset or profiled diameters, allowing multiple diameters to be ground in a single operation.
Inclined Plunge-Cut Grinding: A variant where the wheelhead is inclined by 10°, suitable for grinding flat shoulders or face ends.

Key Features:

Patented CNC height adjustment for rapid setup.
Grinding wheel balancing on two planes to minimize undulations.
Direct drive grinding spindle for low noise.
Automatic grinding gap geometry setting for optimized processes.
Individual CNC dressing of grinding and regulating wheels.

Equipment and Options:

Operator panel for controlling all machine components, offering user convenience and flexibility.
High precision axis drive and guidance with linear roller ways and ball screw drive.
Polymer machine bed for stability and damping.
Various abrasive options with steel or carbon base wheels.
Partial and full enclosure options for maintenance ease.

Additional Features:

Loading systems tailored to customer needs.
Measurement systems for dimensional correction.
Fire protection with automatic sealing and optional extinguishers.
Energy efficiency through optimized machine components.

Technical Data: The document provides detailed specifications for different models, including workpiece dimensions, spindle drive power, and machine weight.

Contact Information: The document lists contact details for JUNKER offices worldwide, including Europe, Asia, and America.

CENTERLESS CYLINDRICAL GRINDING

Open the catalog to page 1

GRINDING PROCESSES PRODUCTIVE ALL THE WAY CENTERLESS GRINDING During centerless cylindrical grinding, the workpiece is not clamped but lies in the grinding gap between the grinding wheel, regulating wheel and support blade. The grinding pressure presses the workpiece against the regulating wheel, which brakes the workpiece to its own peripheral speed. THROUGHFEED GRINDING JUPITER series centerless grinding machines offer substantial production benefits: The patented CNC height adjustment of the support blade minimizes tooling times, automatic adjustment of the grinding gap geometry optimizes...

EQUIPMENT AND OPTIONS ABRASIVE CONTROL SYSTEM Depending on the application, corundum, CBN or diamond is used as an abrasive. When using CBN or diamond, the base wheels are made of steel or carbon. Carbon is light in weight, has vibration-damping properties and remains dimensionally stable even at high speeds. The Erwin Junker Operator Panel was specifically developed to control grinding machines. All machine components are controlled using the operator panel – irrespective of the series and the used control system. The identical structure, intuitive menu guidance and visualization of the workpiece...
