New SEIKI KM-520 | Vertical Machining Centers

Description

The Seiki KM series is the fastest CNC machining center in its class. This machine will exceed the demands of any manufacturer with high volume, high precision machining needs. The compact size consumes very little valuable floor space while the blazing speed will deliver more parts per hour than the competition.

The KM series machines feature a Meehanite cast iron frame and rigid roller type linear slideways for rigidity and fast, precise movement. The 36mm to 40mm diameter ballscrews are class 3 with a double nut pre-loaded design allowing a standard rapid traverse rate of 1417 inches per minute in the all three axes with acceleration of 0.7 to 0.8G. The ABS (Absolute Pulse Coder) servo system does not require zero return. The machines can be started anytime from any position, saving non-productive time. A standard bed flushing system and caterpillar type chip conveyor located behind the machine provides efficient chip removal.

The KM series machines are equipped with a 30 tool twin arm type ATC. The standard 30 station arm type automatic tool changer provides fast, reliable tool selection. Complete tool change time is only 1.5 – 1.7 seconds tool to tool and 2.9 – 3.4 seconds chip to chip. The standard spindle is a 32HP peak / 15HP continuous, 12,000 RPM direct drive spindle that provides rigid tap speeds up to 6000 RPM. A spindle chiller is standard. The CAT-40 Big Plus dual contact taper is standard for rigid milling. Coolant through the spindle preparation is also standard.

The Mitsubishi M80A control is standard and is suitable for a wide range of applications from production to high speed machining applications. The M80A control features a 10.4” touch screen with intuitive smart phone type operation. A dedicated CNC CPU provides phenomenal processing speeds. An all new high response servo system with 1,000,000 pulse encoders is provided for state-of-the-art speed and accuracy. The Mitsubishi control comes with an industry leading 3 year parts and labor warranty! The Fanuc OiM-F Plus control with 10.4” LCD and 2 year warranty is also available.
