Grinding machine selection Which grinder is best suited for machining irregular, curved, tapered, convex, and concave surfaces and for sharpening complex cutters?

Introduction / Context:
Different grinding machines serve distinct geometries. Selecting the correct grinder impacts accuracy, finish, and productivity, especially for complex profiles and multi-edge cutting tools.

Given Data / Assumptions:

• Need to grind irregular, curved, convex/concave, and tapered surfaces.
• Application includes sharpening of milling cutters, drills, reamers, and form tools.

Concept / Approach:
Tool and cutter grinders provide multi-axis motions (e.g., swiveling work head, tilting wheel head, and adjustable tables) enabling complex geometries and precise relief/clearance angles. Jigs and fixtures extend versatility.

Step-by-Step Solution:

Verification / Alternative check:
Manufacturers catalogues list tool and cutter grinders for sharpening helical and form cutters, confirming suitability.

Why Other Options Are Wrong:
Surface grinder: primarily for flat surfaces.Cylindrical grinder: external cylinders and shoulders.Internal grinder: internal bores.Centerless grinder: external cylindrical surfaces without centers; limited profiling.

Common Pitfalls:
Trying to produce complex cutter reliefs on a surface or cylindrical grinder; setups become impractical and inaccurate.

Final Answer:

Tool and cutter grinder
