POLISH MILL V TYPE ASPV mini

Brand: MOLDINO

We’ve added high-precision finishing tools to our small-diameter multi-flute cutting tool series.
The free-cutting edge shape solves issues related to vertical wall cutting.

ISUUE 01 : Inability to achieve desired dimensional accuracy with deflected walls.
Reworking consumes much time.

Proposed solutions
● Insert shapes with enhanced free-cutting capabilities enable to precisely finish deep vertical walls with extended overhangs.
● ASPVmini decreases wall deflection, reducing the time spent on reworking, additional work and modification issues during the finishing process.

Cutting condition

Work material : S50C (220HB)

Machine : Vertical type (BT40)

Solid end mill Tool dia.：φ20mm Revolution：1,432min-1 Feed rate： 572mm/min Depth of cut：ap=8.0mm Cutting width：ae=0.2mm Overhang：OH=100mm（L/D=5）

ASPVmini Tool dia.：φ20mm Revolution：4,775min-1 Feed rate： 2,387mm/min Depth of cut：ap=1.0mm Cutting width：ae=0.2mm Overhang：OH=100mm（L/D=5）

Point !  > Ground chipbreaker

The ground chipbreaker suppresses cutting forces. Work material：S50C（220HB） Cutter：Diameter φ20 Cutting speed：Vc = 300m/min Feed rate： fz=0.1mm/t　 Axial depth of cut （ap）=1.0mm 　 Radial depth of cut （ae）=0.2mm

ISUUE 02 : Requires high verticality, even at deep points where the L/D※ is eight or greater.

                                   ※L/D:Ratio of tool diameter (D) and tool overhang (L)

Proposed solutions
● Vertical cutting improves vertical wall accuracy, even when it’s difficult to cut the wall at constant depth due to extremely long overhangs.

Depth constant cutting Tool dia.：φ11mm Revolution：2,893min-1 Feed rate： 463mm/min Depth of cut：ap=0.5mm Cutting width：ae=0.1mm Overhang：OH=90mm（L/D=8.2） Air-blow

Vertical cutting Tool dia.：φ11mm Revolution：2,893min-1 Feed rate： 463mm/min Pick feed：pf=0.2mm Cutting width：ae=0.1mm Overhang：OH=90mm（L/D=8.2） Air-blow

ISUUE 03 : The tool wears due to prolonged finishing, resulting in unstable surface grade or problems with dimensional accuracy.

Proposed solutions

The ASPVmini inserts use the new grade “TH308” which offers excellent abrasion resistance to maintain high surface grade and accuracy.

Machine：Vertical 3-axis M/C （HSK63）
