Breaking spindles: precision for perfect grinding results

Breaking spindles are essential for precise alignment of Wheels and ensure uniform grinding processes with highest accuracy. Depending on the application, we offer different types of construction with air or water cooling as well as different types of lubrication – for maximum service life and efficiency.

Our portfolio of dressing spindles

In Steinmetz grinding technology you get dressing spindles that are exactly matched to your application. For maximum grinding precision, long service life and reliable processes – from Compact spindle to tailor-made Special production.

Compact dressing spindles (Ø 42–58 mm)

For confined installation spaces and applications with low power requirements. These sizes are optimally suited if the installation conditions in your machine leave little space. Despite compact dimensions, these spindles convince by high speeds and precise rounding. Some models are optionally equipped with cut detection (e.g. Dittel system).

Typical features

Outer diameter: 42–58 mm
Speeds up to 28,400 min-1
Performance: up to approx. 0.4 kW
Lubrication: grease duration lubrication
Cooling: usually without or air cooling

Typical series

AS42x147F
AS58x94F
AS58x111

Areas of application

Tool grinding in compact machines
Retrofit solutions for lack of space

Medium standard spindles (Ø 72–100 mm)

The all-rounder under the dressing spindles – for versatile applications. This category covers a wide range of applications: from tool and mold construction to automated series production. Optionally available with cut detection for process monitoring.

Typical features

Outer diameter: 72–100 mm
Speeds: up to 19,000 min-1
Power: up to 1.2 kW
Cooling: air or oil
Voltages: 220–350 V
Cutting detection via Dittel system possible

Typical series

AS72x205F
AS72x220F
AS80x225F
AS90x250F
AS100x300F

Areas of application

Internal and external circular grinding
Form and profile grinding
Serial and single parts production

High-performance dressing spindles (Ø 120 mm)

For extreme requirements in continuous operation and series production. These spindles are designed for maximum load – with particularly stable mounting, high cooling performance and strong motorization. Ideal for applications with high material removal and long cycle times.

Typical features

Outer diameter: 120 mm
Speeds up to 9.720 min-1
Continuous power up to 3.5 kW
Lubrication: grease duration lubrication
Cooling: air or water cooling

Typical series

AS120x320F
AS120x270F

Areas of application

grinding centers with high ablation
Serial production in hard materials
Applications with continuous operation and closest tolerances

custom productions according to customer request

Not every application can be covered with a standard product. Therefore, we offer you the possibility to manufacture dressing spindles according to your individual requirements. Whether special dimensions, other bearings, special connections or alternative clamping systems – we implement your requirements.

Possible options

Individual dimensions, sleeve lengths or flanges
Special connections for cooling and blocking air
Drive via pulley or directly
Design with or without sensor technology
Production already from small quantities

Typical examples

spindle 139118: Ø 110 mm, 350 mm sleeve length, belt drive
AS63x10F/001: Belt drive, Labyrinthab seal
AS63x10Ö/001: Oil fog lubrication, Ø 63 mm

Areas of application

Machine modernization (retrofit)
Special machinery
Spare parts production of spindle types no longer available

Additional features for your dressing spindles

Belt drive available

In certain spindle types, the drive does not take place via an integrated motor, but via an external Belt. This option is especially relevant for custom productions and offers maximum flexibility for installation in special machines.

Available at: Special productions
Advantages: space-saving installation, independent drive design

Cutting detection / sensor system integrated

For automated processes, we offer spindles with integrated sensor technology (e.g. Dittel). The cut detection increases process reliability, allows reproducible grinding results and prevents tool wear.

Optional for: compact, standard and high-performance spindles
Systems: Dittel-Sensorik (incl. Micro-M sensor, transmitter, receiver)
Benefits: Process control, Safety, Quality assurance
