Product catalog summary

Overview
The JUMAT cylindrical grinding machines by JUNKER offer high versatility, quality, and productivity for both external and internal grinding processes. These machines are customizable to meet specific customer requirements and are suitable for a wide range of industries.

Grinding Process
The JUMAT machines utilize straight and inclined plunge-cut grinding processes. External cylindrical grinding involves clamping workpieces between tips or in a collet chuck, while internal grinding uses high-speed spindles for precise inside surface grinding.

Machine Capabilities
The JUMAT series can perform both OD and ID grinding in a single setup, using CBN and diamond grinding wheels for high-speed and high-performance grinding. The machines can handle complex workpieces like shafts, injection pump parts, and threaded components.

Key Features

High dimensional accuracy with various measuring systems.
Long tool life with CBN or diamond grinding wheels.
Versatility with multiple wheelhead versions.
Fast changeover with a patented 3-point mounting interface.

Special Solutions
The JUMAT series includes specialized solutions like center drive systems for simultaneous grinding of both workpiece ends, and double workpiece headstocks for efficient thread grinding of ball screw nuts.

EQUIPMENT AND OPTIONS IN-PROCESS MEASURING SYSTEM CONTROL SYSTEM A digital measuring head measures the bearing diameter and the concentricity in the process. The control system logs the measured values, calculates the correction data and compensates process influences due to temperature fluctuations or grinding wheel wear. 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...
