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-HX630G #50 is the 50-taper build of Kitamura's 630 mm horizontal: a 630 x 630 mm (24.8 x 24.8 in) pallet under a 54 HP gear-driven spindle, with travels of 1,100 mm (43.3 in) in X, 920 mm (36.2 in) in Y and 1,050 mm (41.3 in) in Z. It is a mid-size machine for parts that need real spindle power, such as steel weldments, iron castings and large valve or pump bodies.

The standard spindle covers 35 to 12,000 rpm through four gear steps, on an NST No. 50 taper with HSK-A100 optional. An 8,000 rpm spindle is the listed alternative. Only power is stated, not torque, so the question to put to Kitamura is how much torque each spindle delivers in its lowest gear, because that is what sets the largest face mill or drill the machine can drive.

Rotation between faces is fast for this class. The B axis is listed at 120 rpm (43,200 deg/min), so a four-sided part loses little time to indexing, and the linear axes move at 60 m/min (2,362 ipm). The tool change is 2.1 sec tool-to-tool and 4.8 sec chip-to-chip. A 62 tool magazine is standard, and it can be replaced with a 122, 162 or 212 tool unit for families of parts that stay set up together.

Sizing is the remaining question. The Mycenter-HX500iG #50 offers the same spindle on a 500 x 500 mm (19.7 x 19.7 in) pallet with 870 mm (34.3 in) of X, and the Mycenter-HX800G moves up to an 800 x 800 mm (31.5 x 31.5 in) pallet with 1,570 mm (61.8 in) of X. Listed accuracy here is ±0.002 mm (±0.000079 in) over the full stroke and ±0.001 mm (±0.000039 in) repeatability, and the supply requirement is 65 kVA at 200 V AC, three-phase.

Strengths & Limitations

Strengths

54 HP No. 50 taper spindle with a four-step gear drive and a 35 to 12,000 rpm range
B axis rotates at 120 rpm (43,200 deg/min), keeping index time low on multi-face parts
Travels of 1,100 mm (43.3 in), 920 mm (36.2 in) and 1,050 mm (41.3 in) over a 630 x 630 mm (24.8 x 24.8 in) pallet
62 tool standard magazine, expandable to 122, 162 or 212 tools
60 m/min (2,362 ipm) rapids with ±0.001 mm (±0.000039 in) repeatability

Limitations

12,000 rpm is the top speed; small-tool work is better served by the 20,000 rpm Mycenter-HX630G #40
The table omits spindle torque and any maximum workpiece weight or size
The 8,000 rpm spindle, HSK-A100 taper and larger magazines are all options
Chip-to-chip time is 4.8 sec, so cycles built from many short operations carry a tool-change cost

Best For

Steel weldments and iron castings on a 630 x 630 mm (24.8 x 24.8 in) pallet Heavy face milling and boring with the 54 HP geared spindle Four-sided parts that index often, helped by the 120 rpm B axis Part families needing up to 212 tools in the magazine

Frequently Asked Questions

01 What spindle does the Mycenter-HX630G #50 use?

An NST No. 50 taper spindle rated 54 HP, gear driven through four steps, with a speed range of 35 to 12,000 rpm. An 8,000 rpm spindle is listed as an option, and HSK-A100 is the optional taper. Torque is not stated in the table.

02 Which is the better fit, the Mycenter-HX630G #50 or the #40?

It depends on the cutters. The Mycenter-HX630G #50 has 54 HP and a No. 50 taper for large tools, with a 62 tool magazine. The Mycenter-HX630G #40 has a No. 40 taper spindle that runs from 20 to 20,000 rpm at 30 HP and a 50 tool magazine, which favours small tools and light alloys. Pallet and travels are identical.

03 How quickly does the pallet rotate between faces?

The rotary indexing speed of the B axis is 120 rpm (43,200 deg/min). Combined with 60 m/min (2,362 ipm) linear rapids, repositioning from one face of a part to the next takes little of the cycle, which helps on parts machined on four sides.

04 What magazine sizes are offered?

62 tools as standard, with 122, 162 and 212 tool magazines as options. Tool change time is 2.1 sec tool-to-tool and 4.8 sec chip-to-chip. A larger magazine is worth specifying if several part numbers will share the machine without tool reloading.

05 What is the next size up from the Mycenter-HX630G #50?

The Mycenter-HX800G has an 800 x 800 mm (31.5 x 31.5 in) pallet and travels of 1,570 mm (61.8 in), 1,300 mm (51.2 in) and 1,400 mm (55.1 in). The Mycenter-HX800G keeps the 35 to 12,000 rpm No. 50 taper spindle range and the 62 tool magazine, and it weighs 29,665 kg (65,400 lb).
