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
The Kitamura Mycenter-HX500iG #50 puts a No. 50 taper spindle rated at 54 HP on a 500 x 500 mm (19.7 x 19.7 in) pallet. It is the heavy-cutting build of the HX500iG, keeping the pallet and travels of the #40 machine but adding the larger taper, a 35 to 12,000 rpm speed range and a bigger standard magazine.
Drive to the spindle is through a four-step gearbox. Gear steps exist to multiply torque at low speed, which is where large face mills, big drills and boring bars do their work in steel and cast iron. At the other end, 12,000 rpm is a high top speed for a spindle of this taper and keeps finishing passes productive. An 8,000 rpm spindle is listed as an option. The table states power but not torque, so ask Kitamura for the torque curve of each spindle before choosing between them. HSK-A100 is the optional taper.
Travels are 870 mm (34.3 in) in X, 800 mm (31.5 in) in Y and 930 mm (36.6 in) in Z, and the machine accepts a workpiece up to 800 mm (31.5 in) in diameter and 1,100 mm (43.3 in) high. Long 50-taper tools use up Z clearance quickly, so check the 930 mm of Z against the longest boring bar and the widest fixture together.
Tool changes take 2.1 sec tool-to-tool and 4.8 sec chip-to-chip. The standard magazine holds 62 tools, with 122, 162 and 212 tool magazines optional. Rapids are 60 m/min (2,362 ipm) and the B axis turns at 120 rpm (43,200 deg/min). Listed positioning accuracy is ±0.001 mm (±0.000039 in) over the full stroke with ±0.0005 mm (±0.00002 in) repeatability. Plan for a 75 kVA, 200 V AC, three-phase supply. The control is Arumatik-Mi.

Strengths & Limitations
Strengths
- No. 50 taper spindle rated at 54 HP and driven through a four-step gearbox, on a compact 500 x 500 mm (19.7 x 19.7 in) pallet
- 35 to 12,000 rpm speed range, so the spindle that roughs with large cutters can also finish at speed
- 62-tool standard magazine, with 122, 162 and 212 tool magazines available
- Accepts workpieces up to 800 mm (31.5 in) in diameter and 1,100 mm (43.3 in) high
- Positioning accuracy of ±0.001 mm (±0.000039 in) over the full stroke and repeatability of ±0.0005 mm (±0.00002 in)
Limitations
- Tool change is 2.1 sec tool-to-tool and 4.8 sec chip-to-chip, which adds up on parts made of many short operations
- Requires a 75 kVA, 200 V AC, three-phase supply
- Top speed is 12,000 rpm; the Mycenter-HX500iG #40 reaches 20,000 rpm for small-tool work
- Neither a maximum pallet load nor a spindle torque figure is given in the table
- HSK-A100 and the 8,000 rpm spindle are options rather than standard equipment

Frequently Asked Questions
01
In the spindle and the magazine. The Mycenter-HX500iG #50 has a No. 50 taper spindle at 35 to 12,000 rpm with 54 HP and a 62 tool magazine. The Mycenter-HX500iG #40 has a No. 40 taper spindle at 20 to 20,000 rpm and a 50 tool magazine. Pallet size and travels are common to both: 500 x 500 mm (19.7 x 19.7 in) and 870 x 800 x 930 mm.
02
The standard spindle runs from 35 to 12,000 rpm and is driven through a four-step gearbox. An 8,000 rpm spindle is listed as an option. Power is given as 54 HP. The table does not state torque, so request the torque curve for both spindles if low-speed roughing is the main job.
03
The maximum workpiece is 800 mm (31.5 in) in diameter and 1,100 mm (43.3 in) high, on a 500 x 500 mm (19.7 x 19.7 in) pallet. Axis travels are 870 mm (34.3 in) in X, 800 mm (31.5 in) in Y and 930 mm (36.6 in) in Z. No maximum workpiece weight is listed, so confirm it for heavy castings.
04
The standard magazine holds 62 tools. Optional magazines hold 122, 162 or 212 tools. A tool change takes 2.1 sec tool-to-tool and 4.8 sec chip-to-chip. The standard taper is NST No. 50, with HSK-A100 as the option.
05
Only if the work needs the room. The Mycenter-HX630G #50 carries the same No. 50 taper, 35 to 12,000 rpm, 54 HP spindle and 62 tool magazine on a 630 x 630 mm (24.8 x 24.8 in) pallet, with travels of 1,100 mm (43.3 in), 920 mm (36.2 in) and 1,050 mm (41.3 in). The Mycenter-HX500iG #50 covers parts that fit a 500 x 500 mm pallet and 870 mm (34.3 in) of X.
