Profile accuracy and stable dressing performance in creep-feed grinding

Match the workpiece profile and rotary dresser

EHWA develops rotary dressers around your workpiece contour. They profile the grinding wheel for subsequent turbine-blade machining. The programme combines custom geometry, high precision, long tool life and stable dressing performance in creep-feed grinding.

Custom roll design and precise profiling

EHWA identifies three connected benefits:

Tool feature Application benefit
Roll design based on the workpiece Match the dressing contour to the blade profile
Long tool life and high tool precision Consider useful life and precise profile machining together
Stable dressing performance in creep-feed grinding Support consistent profiling during the creep-feed grinding process

Contour, grinding wheel, mounting and dressing strategy are designed together. Drawings and inspection records help match profile quality, surface requirements and dressing intervals.

Four profile-contact arrangements

Four contact positions illustrate profile machining. Blue shows the upper profile; grey shows the blade/counterprofile. The arrangement is matched to your workpiece drawing.

Profile contact 1: horizontal blade body with a raised profile area at the side.

Discuss your turbine application

Provide the blade drawing, material, machine, mounting and grinding wheel. Add your existing rotary dresser, dressing strategy and required profile and surface quality. Inspection records, wear patterns and dressing intervals support the comparison. Together, we match the design to your production process.
