72713 Contact Wheel Belt Grinder for Turbine Blade Grinding

---

The IMM 72713 contact wheel belt grinder is designed for efficient and precise finishing operations across a wide range of applications.

Key technical features include:

• belt dimensions up to 50 x 3,500 mm  
• contact wheel diameters from Ø 20 mm to 120 mm  
• selectable spindle speeds from 700 to 2,800 rpm  
• three-stage V-belt drive for flexible speed selection  
• robust and rigid machine design for low vibration  
• compact footprint for space-saving integration  

The machine operates at 400 V, 3-phase, 50 Hz and is designed for industrial use with protection class IP54. Other electrical variants are available.

The 72713 belt grinding machine is used across multiple industries for precision surface finishing of complex components.

Typical applications include:

• turbine blades and guide vanes (manual processing or CNC finishing with SPE machines)  
• medical implants and orthopedic components (e.g. Stryker applications)  
• knives, tools and precision parts  
• cast components and freeform surfaces  

The machine is particularly effective for:

• grinding inner radii using small contact wheels  
• polishing convex and concave surfaces  
• slack belt finishing of sensitive geometries  
• edge preparation and surface blending  
• repair and rework operations  

Compared to automated CNC systems, the 72713 offers maximum flexibility for small batch production and complex geometries. For automated turbine blade finishing and higher production volumes, see our SPE CNC turbine blade grinding and polishing machine.

The 72713 enables both contact wheel grinding and slack belt finishing within one machine.

Contact wheel grinding is used for:

• defined radii and edge geometries  
• controlled stock removal  
• repeatable surface finishing  

Slack belt grinding allows:

• gentle polishing of sensitive surfaces  
• finishing of freeform geometries  
• blending and surface smoothing  

This combination makes the machine ideal for turbine blade finishing, implant polishing and precision manual grinding tasks. For fully automated processing of turbine blades with consistent cycle times, explore our SPE CNC solution.

The 72713 belt grinder can be configured with various options depending on application requirements:

• frequency converter for infinitely variable belt speed  
• braking system for rapid spindle stop  
• integrated machine lighting
• electric height adjustable feature for ergonomic adjustment of working height  

Different motor configurations are available, including:

• 2.2 kW / 1,500 rpm  
• 3.0 kW / 1,500 rpm  
• 4.0 kW / 1,500 rpm  

With frequency converter:

• speed range approx. 700 – 2,800 rpm

• high flexibility for complex and changing geometries  
• fast changeover of contact wheels  
• stable and repeatable surface quality  
• precise control of contact pressure  
• ideal for repair work and small batch production  
• suitable for aerospace and medical applications  
• compact and robust industrial design
