Overview

The Kitamura Mycenter-3020G is a vertical machining center with a four-step gear-driven spindle that runs from 20 to 20,000 rpm on an NST No. 40 taper. Travels are 762 mm (30 in) in X and 510 mm (20.1 in) in both Y and Z, over a 500 × 860 mm table.

Four gear steps on a No. 40 spindle explain the width of that speed range. Low gears multiply motor torque for drilling, tapping and face milling at a few hundred rpm; the top step carries the spindle to 20,000 rpm for small cutters. The motor is listed at 20 HP, so the machine reaches its cutting force through gearing, not through a large motor. Kitamura's table gives no torque figure, which is worth requesting, since torque in each gear step is what this design is about.

The Mycenter-3XV is the alternative on nearly the same travels, 760 mm (29.9 in) by 510 mm (20.1 in) by 510 mm (20.1 in). The Mycenter-3XV lists 41 HP and a 50 - 15,000 rpm range, with rapids of 52 m/min (2,047 ipm) in X and Y against 50 m/min (1,969 ipm) here, and 42 m/min (1,654 ipm) in Z against 36 m/min (1,417 ipm).

Tool changes take 2.4 sec tool to tool and 4.6 sec chip to chip from a 30-tool magazine. The control is Kitamura's Arumatik-Mi with 8,190 block look-ahead, which matters for the long, finely segmented toolpaths that 20,000 rpm finishing produces. Electrical demand is 30 kVA at 200 V AC, three-phase.

Limitations

Motor power is 20 HP, against 41 HP on the Mycenter-3XV
30 tools is the only magazine size in the table; the Mycenter-4XV carries 40 tools
Z rapid of 36 m/min (1,417 ipm) is slower than the 50 m/min (1,969 ipm) of X and Y
No spindle torque or table load figure is published

Best For

Die and mould work mixing low-speed roughing and 20,000 rpm finishing 3D surfacing that benefits from 8,190 block look-ahead Parts within 762 mm (30 in) by 510 mm (20.1 in) Shops that want one spindle for tapping, drilling and high-speed finishing

Frequently Asked Questions

01 Why does the Mycenter-3020G have a gear-driven spindle?

Kitamura lists the spindle as four-step gear driven with a range of 20 - 20,000 rpm and a 20 HP motor. Gear steps let a motor of that size deliver more torque at low speed than it could directly, while still reaching 20,000 rpm in the top step. The table does not give torque values for each step.

02 How does the Mycenter-3020G differ from the Mycenter-3XV?

The Mycenter-3XV lists a 41 HP spindle with a 50 - 15,000 rpm range and rapids of 52 m/min (2,047 ipm) in X and Y. The Mycenter-3020G has the 20 HP four-step geared spindle reaching 20,000 rpm and rapids of 50 m/min (1,969 ipm) in X and Y. Travels and tool capacity, 30 tools, are almost the same on both.

03 What control does the Mycenter-3020G use?

Kitamura's own Arumatik-Mi control, listed with 8,190 block look-ahead. A long look-ahead lets the control plan feed rate through dense point-to-point toolpaths, which is where a 20,000 rpm spindle spends its time on mould surfaces.

04 What are the tool change times and tool capacity?

The magazine holds 30 tools. Tool-to-tool time is 2.4 sec and chip-to-chip time is 4.6 sec. No optional larger magazine appears in Kitamura's table for this model.

05 What are the travels and table size of the Mycenter-3020G?

762 mm (30 in) in X, 510 mm (20.1 in) in Y and 510 mm (20.1 in) in Z. The table measures 500 × 860 mm. The machine needs a 30 kVA supply at 200 V AC, three-phase.
