How much does the Kitamura Mycenter-HX630G #40 cost?
Estimated price range
Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Kitamura Machinery. Configuration moves it a long way.
Overview
A 20,000 rpm No. 40 taper spindle over a 630 x 630 mm (24.8 x 24.8 in) pallet is an uncommon pairing, and it defines the Kitamura Mycenter-HX630G #40. Horizontals of this pallet size are more often built around a larger taper. This one is aimed at big parts that are cut with small and medium tools: large aluminium housings, plates and frames, or tombstones loaded with many smaller components.
The spindle is driven through a four-step gearbox, runs from 20 to 20,000 rpm and is rated at 30 HP. HSK-A63 is optional in place of the NST No. 40 taper. The gear steps give the low end of the range some pull for bigger cutters, but 30 HP is the ceiling. For sustained heavy roughing the Mycenter-HX630G #50 is the alternative, with a No. 50 taper and 54 HP at a 12,000 rpm top speed.
Travels are 1,100 mm (43.3 in) in X, 920 mm (36.2 in) in Y and 1,050 mm (41.3 in) in Z, all well beyond the pallet dimensions, so fixtures can overhang and tools can clear a tall tombstone. Rapids are 60 m/min (2,362 ipm) and the tool change is 1.3 sec tool-to-tool, 3.8 sec chip-to-chip. The B axis is the slower element at 33.3 rpm (12,000 deg/min). On parts that index often, include that rotation time in the cycle estimate.
Accuracy is listed as ±0.002 mm (±0.000079 in) over the full stroke with ±0.001 mm (±0.000039 in) repeatability. The magazine holds 50 tools as standard, and 62, 100, 150, 200 and 300 tool magazines are options. Supply is 65 kVA at 200 V AC, three-phase. The table gives no maximum workpiece size or weight, which is the first thing to ask about for a machine meant to carry large fixtures.

Strengths & Limitations
Strengths
- 20 to 20,000 rpm four-step gear-driven spindle rated 30 HP, on a 630 x 630 mm (24.8 x 24.8 in) pallet
- Long travels for a 40-taper machine: 1,100 mm (43.3 in) in X, 920 mm (36.2 in) in Y and 1,050 mm (41.3 in) in Z
- 1.3 sec tool-to-tool and 3.8 sec chip-to-chip tool change with 60 m/min (2,362 ipm) rapids
- Magazine can grow from the standard 50 tools to 62, 100, 150, 200 or 300 tools
- Listed accuracy of ±0.002 mm (±0.000079 in) over the full stroke and ±0.001 mm (±0.000039 in) repeatability
Limitations
- Spindle power is 30 HP; the Mycenter-HX630G #50 offers 54 HP for heavier cuts
- B axis rotates at 33.3 rpm (12,000 deg/min), which adds time on parts with many index moves
- No maximum workpiece weight, diameter or height is listed for this model
- HSK-A63 and every magazine above 50 tools are options
- Needs a 65 kVA, 200 V AC, three-phase supply

Frequently Asked Questions
01
For speed with small tools. The #40 spindle runs from 20 to 20,000 rpm and is rated 30 HP, and its changer works at 1.3 sec tool-to-tool. That suits large light-alloy parts and fixtures full of small components. The Mycenter-HX630G #50 tops out at 12,000 rpm but has 54 HP and a No. 50 taper for bigger cutters.
02
1,100 mm (43.3 in) in X, 920 mm (36.2 in) in Y and 1,050 mm (41.3 in) in Z, over a 630 x 630 mm (24.8 x 24.8 in) pallet. Rapid traverse is 60 m/min (2,362 ipm). Maximum workpiece dimensions and weight are not stated in the table.
03
The listed rotary indexing speed is 33.3 rpm (12,000 deg/min). That is slow next to the linear axes at 60 m/min (2,362 ipm), so a part program with many rotations between faces should have the indexing time counted in the cycle.
04
50 tools in the standard magazine. Kitamura lists 62, 100, 150, 200 and 300 tool magazines as options. The standard taper is NST No. 40 and HSK-A63 is optional. Tool change time is 1.3 sec tool-to-tool and 3.8 sec chip-to-chip.
05
The Mycenter-HX500iG #40 has the same 20 to 20,000 rpm four-step gear-driven spindle on a smaller 500 x 500 mm (19.7 x 19.7 in) pallet, with travels of 870 mm (34.3 in), 800 mm (31.5 in) and 930 mm (36.6 in). The Mycenter-HX630G #40 adds pallet area and reach: 1,100 mm (43.3 in), 920 mm (36.2 in) and 1,050 mm (41.3 in).
