VI - PRO Carbide Endmills ― 4 Flute
ALCRO-MAX Coating for the VI-PRO
ALCRO-MAX has remarkable wear resistance at higher speeds and feeds due to excellent thermal
properties under high mechanical loads, and can be used for roughing and finishing operations.
Because of its chromium addition, surface finish of the work piece (Ra, Rz) remains consistent and
low during the life of the tool. ALCRO-MAX particularly excels when machining under wet or MQL
(minimum quantity lubrication) conditions.
This coating excels in titanium, high temperature alloys, and hardened stool steel 35 HRc or greater.
Our case histories have shown ALCRO-MAX out performs ALTIN in VI-Pro High Performance
Endmills. ALCRO-MAX is recommended for a wider range of materials such as stainless steels, high
strength tool steels as well as carbon steels and ductile and grey cast irons. This coating has the
highest thermal stability of any coating TITAN offers.
Speed and Feed Calculations • Running at higher SFM; heavier chip
loads than conventional endmills.
RPM = (3.82 x SFM) ÷ Dia.
IPR = IPM ÷ RPM • Speed and feed chart parameters are
SFM = (RPM x Dia) ÷ 3.82 for 4 flute diameter slotting.
IPM = IPT(chip load) x No. of teeth x RPM
IPT(chip load) = IPM ÷ (No. of teeth x RPM) • Recommended slotting depth = 1x
diameter.
V
• Tool holding important for maximizing
S WX tool life. Minimize TIR.
• Max ramp angle recommended 3° or
less.
