MACHINE ACCURACY Inches (mm)
(*) Recommended face mills:
1. Mitsubishi SE445RO405E, 4" diameter, 5 teeth, 45 o lead
angle, +19 o axial rake, -2 o radial rake, +13 o cutting rake.
2. Seco/Carboloy R220. 13-04.00-12, 4" diameter, 6 teeth, 45 o lead
angle, +20 o axial rake, -3 o radial rake, +12 o cutting rake.
Parameters:
5 hp 6 gpm (3.73 kW, 22.7 L /min) hydraulic
power unit.
Mist coolant.
Recommended milling cutter with sharp milling
inserts (see chart below).
A-36 steel plate.
Skilled operator.
Accurate alignment equipment (laser, optics,
etc.)
Machine components trammed.
Bed fully supported.
Milling completed in one setup with machine in
horizontal position.
Results:
.004 (.102) flatness over 9 x 48 (228.6 x
1219.2) area (ram on one side of the bed)
(A-36 steel plate).
.006 (.152) flatness over 9 x 48 (228.6 x
1219.2) area on each side of bed (ram moved
straight across to opposite side of bed) (A-36
steel plate). Improved accuracies may be
obtained by resetting the Z-axis and re-
tramming the milling head.
