Seiki UT Series – Tapping Centers

Ultra Speed Milling & Tapping Center

The Seiki UT series machines are the fastest CNC milling and tapping centers in their class and are well suited to high volume machining as well high speed 3D machining. These machines will exceed the demands of any manufacturer with high volume, high precision machining needs. Their compact size consumes very little valuable floor space while the blazing speed will deliver more parts per hour than the competition.

UT series machines feature a fixed column / moving table type design and are constructed with Meehanite cast iron frame and rigid linear slideways for rigidity and fast, precise movement. The XYZ axis ballscrews are class 3 with a double nut pre-loaded design allowing for industry-leading rapid traverse rates in all 3 axes as well as impressive acceleration in the Z axis. 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.  

Two types of high speed ATC systems are available. The standard is a 20 tool servo turret type ATC while the a 24 tool twin arm type ATC is optional.  The standard 20 station turret style servo automatic tool changer provides fast, reliable tool selection. The optional 24 station high speed arm type ATC provides an increase in Z axis travel and even faster tool change times.

The standard spindle is a 7.4HP 30 min. /  5HP continuous direct drive spindle that provides rigid tap speeds up to 6,000 RPM.  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 (pump system optional). 24,000 RPM high speed and 12,000 RPM high torque spindles are optionally available.

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.
