CLEARANCE CUTTERS - SQUARE END MILL
What is a Clearance Cutter (Square End Mill)?
A clearance cutter, more commonly known as a square end mill, is a versatile rotary cutting tool used in CNC milling machines. It features a flat bottom with sharp, square cutting edges along its sides. This design allows clearance cutters to excel at these primary functions:
Clearance cutters operate within CNC milling machines, which move the workpiece with extreme precision against the rotating cutting tool.
Clearance cutters, also known as square end mills, are essential tools in precision machining. Their manufacturing process involves a meticulous combination of materials science, advanced machining, and quality control. Here's a breakdown of the key steps:
1. Material Selection
2. Blank Formation
3. Flute Grinding
4. End Geometry Creation
5. Sharpening and Finishing
6. Quality Inspection
General Size Ranges for Clearance Cutters (Square End Mills):
