  5. LBE Laser BallEndmill • high precision finishing ball endmil

  6. Laser Mill Through coolant hole High precision Screw clamp • Rigid holder • steel • - carbide Features of Laser Mill • High precision finish ball endmill • Simple design of rigid holder • MQL for optimal coolant action for mold machining • Harder grade for long tool life

  7. Laser Mill • Comparison of Indexable Endmill

  8. Laser Mill General type - Steel shank : 25 type - Steel + Carbide brazing shank : 16 type - Steel + Carbide brazing shank : 16 type (Strengthening holder part) Modular type - Steel modular : Head(7 type), Adaptor(29 type) - Carbide : 12 type - Carbide : 12 type (Strengthening holder part)

  9. Radial force Radial force Radial force Feed force Feed force Feed force Laser Mill High feed mechanisms (LFH) • Specially designed cutting edge line enables the good surface roughness • even under the high feed machining 1. Large AA⁰ + Minor cutting edge angle 2. Tangential edge line between minor and major cutting edge 3. Smooth chip evacuation due to recess part ※ According as the approach angle becomes larger, feed force decreases gradually.

  10. Laser Mill • Chip geometry • LFH insert : Corner R programming (mm) (mm/t)

  11. Laser Mill Classification of endmill

  12. Laser Mill • LBE 6 in 1 system R-tolerance Under 0.01 mm LBE * PC210F : PVD (TiAlN) + Super fine grain substrate 6 in 1 system Ball type corner “R” High Feed Chamfer LRH LCF LFH LBH UP UP LBS LR
