SR CNC SERIES

Product catalog summary

Overview

GER-Máquinas Herramienta, S.L., based in Itziar-Deba, Spain, has been manufacturing grinding machines since 1952. Their product range includes cylindrical grinders (vertical and horizontal), rotary table flat surface grinders (notably the SR CNC series), internal grinders, and other specialized grinding machines. The company emphasizes advanced features, customization, and high precision.

1. Machine Types and Models

Cylindrical Grinders: Available in vertical and horizontal configurations.
Rotary Table Flat Surface Grinders: SR CNC series with models ranging from smaller sizes (e.g., 6200) up to large capacities (e.g., 14720).
Internal and Specialized Grinders: Machines designed for internal grinding and other specific applications.

2. Construction and Materials

All major components of the SR CNC surface grinders are constructed from high-quality perlitic cast iron, ensuring rigidity and vibration damping. The machines feature a ribbed, rigid box section design and a "T"-shaped main bed supporting the moving column. This design maintains stable grinding torque regardless of the grinding wheel’s transverse position, critical for precision.

3. CNC Control and Software Features

Customers can select between Fanuc or Fagor latest-generation CNC systems, including motors, drivers, and regulators from the same brand. The CNC interface is user-friendly with visual macros, suitable for operators of varying experience levels. Key software capabilities include:

Simple machine-job setup and dimensional correction.
Parameter input via teach-in method.
Two-axis interpolation for precise profile following.
Customizable working cycles (e.g., creep feed, toothed bar grinding).
Control of additional axes such as spindle, rotary table, and coolant nozzle.
Axis inversion to machine parts longer than the machine’s longitudinal capacity.
Direct programming from drawing profiles.
Wheel data storage and automatic wheel dressing.
Multi-language interface and real-time intervention during automatic cycles.
Remote diagnostics and fast internet-based service support.

4. Machine Dimensions and Capacities

The SR CNC series offers a broad range of capacities tailored to different grinding needs:

Transverse grinding capacity: 500 mm to 1000 mm.
Longitudinal grinding capacity: 1000 mm up to 6000 mm.
Table to spindle axis height: 335 mm to 660 mm.
Maximum grinding height: 1000 mm to 2500 mm.
Maximum job weight: up to 30,000 kg depending on model.
Working resolution: 0.001 mm.
Total installed power: 22 kW to 46 kW.
Wheel diameters supported: 550 mm to 1100 mm.
