Gear shaper cutters

TSA shaper cutters are designed under the concept of profile optimization to maximize tool life, assuring dimensions of the part within required tolerances. This will allow maximum number of sharpening operation and pieces per tool, reducing the tool impact on cost per piece.

Manufacturing process is highly controlled. Aftervacuum heat treatment, shaper cutter profiles are ground on 5-axis grinding machines, achieving maximum precision and being able to manufacture up to DIN AAA quality.

Applications and componentsInternal/external gear and rack shaping; shaping of spur cylindrical toothed transmissions, helical shaping up to 45º, double helical (chevron/herringbone); tandem cutting
