Seiki KT-360D Milling and Tapping Center

Description

The Seiki KT series is the fastest CNC milling and tapping 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 machine is a moving column / fixed table type design with rotary pallet changer.

The machine is a traveling column type design where the worktable is stationary. The APC unit, located in front of the machine, provides easy access and slashes idle time. The APC is a built-in type rotary type pallet changer mounted in front of the machine. It exchanges the fixed tables in only 4.5 seconds. The rotary pallet uses a hydraulic cylinder to rotate the pallet and a hirth coupling hydraulic clamping mechanism to clamp the pallet in place without lifting for excellent repeatability. The center port of the APC unit is pre-plumbed for hydraulic or pneumatic fixturing.

It features a Meehanite cast iron frame and rigid linear slideways for rigidity and fast, precise movement. The 36mm (1.42”) diameter ballscrews are class 3 with a double nut pre-loaded design allowing a standard rapid traverse rate of 2362 inches per minute in the Z axis with acceleration of 1.0G. The ABS (Absolute Pulse Coder) servo system does not require zero return. The machine can be started anytime from any position, saving non-productive time. A standard bed flushing system pushes chips to the rear of the machine. The optional caterpillar chip conveyor provides efficient chip removal.

The KT-360D is equipped with a 21 tool servo turret type ATC. The KT-360D’s standard 21 station turret style servo automatic tool changer provides fast, reliable tool selection. Complete tool change time is only 1.07 seconds tool to tool and 1.36 seconds chip to chip.

The standard spindle is a 28HP peak / 6.5HP continuous, 15,000 RPM direct drive spindle that provides rigid tap speeds up to 6000 RPM. For 40 taper milling performance in a compact 30 taper machine, the optional 10,000 RPM High Torque spindle produces 28HP peak / 11.3 HP continuous with a whopping 120Nm of torque. An optional 24,000 RPM direct drive spindle with 35HP peak / 5 HP continuous delivers high RPM for aluminum / magnesium parts machining as well as an excellent choice for graphite. A spindle chiller is standard. The BBT-30 (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.
