Overview

The Kitamura Mycenter-3020G Sparkchanger adds a 2-station APC with 180-degree rotation to the Mycenter-3020G, so one pallet can be loaded while the other is under the spindle. The machine underneath is unchanged in the listed figures: 762 mm (30 in) of X, 510 mm (20.1 in) of Y and Z, and a 20 HP gear-driven spindle that reaches 20,000 rpm.

What the pallet changer changes is how the day runs. On the standard machine the spindle stops for every unload, clean-down and reload. Here that work moves to the outside station, and the interruption shrinks to the pallet rotation. The gain is largest on short cycles and on parts that take time to clamp, and smallest on long mould programs where loading is a minor share of the hours. Kitamura's table gives no pallet change time and no pallet load for this model, so ask for both; fixture weight on a rotating pallet is usually the first constraint.

The listed table size is 500 × 860 mm (19.7 × 33.9 in). Cutting specifications follow the base model: a four-step geared NST No. 40 spindle with a 20 - 20,000 rpm range, 30 tools, 2.4 sec tool to tool and 4.6 sec chip to chip, and rapids of 50 m/min (1,969 ipm) in X and Y and 36 m/min (1,417 ipm) in Z.

Control is the Kitamura Arumatik-Mi with 8,190 block look-ahead, and the supply requirement is 30 kVA at 200 V AC, three-phase. With two pallets feeding one 30-tool magazine, tool capacity can become the limit if each pallet carries a different job, so plan the tool list for both before committing.

Strengths & Limitations

Strengths

2-station APC with 180-degree rotation lets parts be loaded during the cut
Same 762 mm (30 in) by 510 mm (20.1 in) by 510 mm (20.1 in) travels as the Mycenter-3020G
Four-step gear-driven spindle, 20 - 20,000 rpm, 20 HP, NST No. 40
Tool changes of 2.4 sec tool to tool and 4.6 sec chip to chip
Arumatik-Mi control with 8,190 block look-ahead

Limitations

No pallet change time or pallet load is given in Kitamura's table
The 30-tool magazine has to serve the jobs on both pallets
Spindle power is 20 HP; the Mycenter-3XV lists 41 HP for heavier roughing
A pallet changer adds little on long single-part programs where loading time is small

Best For

Repeat batches where clamping takes as long as cutting Running two different fixtures alternately on a 2-station APC High-speed finishing at up to 20,000 rpm with parts loaded during the cut Fixtured parts within the 500 × 860 mm (19.7 × 33.9 in) table

Frequently Asked Questions

01 What is the Sparkchanger on the Mycenter-3020G?

It is Kitamura's name for the pallet changer on this model, listed as a 2-station APC with 180-degree rotation. Two pallets swap places by rotating, so the operator sets up one outside the work zone while the other is machined.

02 How long does a pallet change take on the Mycenter-3020G Sparkchanger?

Kitamura's table for this model does not state a pallet change time or a pallet load. It lists the changer as a 2-station APC with 180-degree rotation and gives tool change times of 2.4 sec tool to tool and 4.6 sec chip to chip. Ask for the pallet figures with the quotation.

03 Is the spindle the same as on the standard Mycenter-3020G?

Yes, in the listed figures. Both show a four-step gear-driven NST No. 40 spindle with a 20 - 20,000 rpm range and 20 HP, the same travels of 762 mm (30 in), 510 mm (20.1 in) and 510 mm (20.1 in), and 30 tools.

04 What control and power supply does the Sparkchanger version use?

The control is the Kitamura Arumatik-Mi, listed with 8,190 block look-ahead. The machine needs 30 kVA at 200 V AC, three-phase. Rapids are 50 m/min (1,969 ipm) in X and Y and 36 m/min (1,417 ipm) in Z.
