Machine Overview

This compact 5 axis grinder is ideal for grinding complex geometries, particularly in the case of guide and rotor blades as well as heat shields for aircraft turbines. The workpieces to be machined are loaded ergonomically directly from the front into the working space. Heavy workpieces with a suspension device can be loaded from the top with a crane. The compact and space-saving design allows optimal use of the existing production area and enables effective production flow.

High efficiency and high torque

The high performance spindle drive enables the combination of different grinding processes, such as creep feed grinding with corundum or CBN grinding. Even at low speeds, full power and high torque remain available. The robust tool holding fixture allow wide machining contours to be realized at high removal rates. The grinding process can be performed with emulsion or oil. The high speed spindle provides optimal machining conditions for challenging grinding and milling processes in one clamping.

Process optimized coolant supply

The 2-axis controlled coolant nozzle enables an optimal coolant supply to the tool or workpiece. Nozzles are available on the grinding support for drilling and milling tools, and a coolant supply can be provided through the spindle.

Thanks to integrated grinding wheel cleaning, the grinding wheel remains clean and sharp for longer periods during grinding. This increases the removal rates while reducing the grinding wheel wear.

Machine Overview

Higher main axis speeds, greater acceleration and increased system rigidity - the combination of these consistently optimized essential performance characteristics means increased productivity while improving component quality. These features distinguish the PROFIMAT XT as a robust and effective production grinding machine that consistently builds on the experience and quality of the highly successful PROFIMAT MT.

To meet the different demands of everyday production and for flexible technological applications, Blohm developed the new machine as a series. The comprehensive range of accessories combined with the modular PROFIMAT XT system (sizes from 400x800 to 600x2000mm) makes this new machine generation an optimal grinding machine for all customers.

In addition to high-quality machine elements such as ground ball linear drive, optimized ductile cast iron and precision guidelines, this generation offers the operator a completely new user interface. The three-part control panel now offers customizable screen areas. The information relevant to the required work steps can be programmed and retrieved for the specific customer. The possibilities offered here range from component diagrams, 3D models, user manuals and electric diagrams to GripsProfile, Blohm's proprietary programming system for profiling of grinding wheels. This area also offers the possibility to call up screens for coolant, statuses and process monitoring based on the Industry 4.0 concept.
