Description

CNC Spring End Grinding Machine GA20

Key Features:

Two vertical spindles with grinding wheels for simultaneous processing of the top and bottom ends of the spring.
Automatic feeding via a loading tray, ensuring uniform grinding.
CNC control with a touchscreen HMI interface for easy parameter programming (feed rate, clamping force, grinding depth).
Two operating modes:
- Through grinding (manual setup + manual cycle).
- Automatic cycle with digital control (feed with precise positioning).
Electronic system for monitoring spring height after processing.
Automatic reset and preparation for the next cycle for continuous production.

Applications:

Processing of compression springs in automotive, aerospace, machinery manufacturing, and other industries.
Achieving specified height and end parallelism.
