How much does the Mazak INTEGREX e-420H-S cost?
Estimated price range
Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.
Overview
The Mazak INTEGREX e-420H-S is the second-spindle form of a horizontal multi-tasking machine in the INTEGREX e-H family. Its table lists a 4,000 rpm main spindle, a sub spindle described as equivalent to the main, and a 12,000 rpm B-axis milling spindle.
Mazak describes the INTEGREX e-H series as machines for large workpieces that take a part from raw material to final machining on one machine. The series has a built-in motor spindle, with temperature-controlled cooling oil circulated around the spindle bearings and the headstock to limit thermal displacement. Its milling spindle has an automatic tool changer and can use the same tool vertically, horizontally or at any angle. The control is the MAZATROL SmoothAi. The models Mazak names in the series are the INTEGREX e-500H, e-500H-S, e-670H, e-670H-S and e-800H, with the -S models marked Second Spindle. The e-420H-S is not among the names on that list.
The listed figures for this model are a standard turning length of 1,524 mm (60 in), X travel of 845 mm (33.27 in) and Z travel of 1,388 mm (54.65 in), a B-axis range of 240° (-30° to +210°) and continuous C-axis rotation on both spindles. Main spindle power is listed as 30 hp (22 kW) continuous and 40 hp (30 kW) on the 30-minute rating. The milling spindle is listed at 22 kW (29.3 hp) with a No. 40, CAPTO C6 or HSK-T63 taper, the magazine at 40 tools with 80 or 120 optional, and the weight at approximately 22,000 kg (48,502 lb). For scale, the INTEGREX e-500H lists 63 in (1,600 mm) of Z travel, a CAT50 milling taper and 49,824 lb (22,600 kg).

Strengths & Limitations
Strengths
- Sub spindle listed as equivalent to the 4,000 rpm main spindle, with continuous C-axis rotation on both
- Listed main spindle power of 30 hp (22 kW) continuous and 40 hp (30 kW) on the 30-minute rating
- B-axis milling spindle listed at 12,000 rpm and 22 kW (29.3 hp), with a No. 40, CAPTO C6 or HSK-T63 taper
- 40-tool magazine as listed, with 80 or 120 tools optional
- Series design per Mazak: built-in motor spindle with temperature-controlled cooling oil around the spindle bearings and headstock
Limitations
- Not named in Mazak's INTEGREX e-H model list, which gives the e-500H, e-500H-S, e-670H, e-670H-S and e-800H
- Listed Z travel of 1,388 mm (54.65 in) is shorter than the listed 1,524 mm (60 in) turning length, so the working length needs confirming
- Bar work is limited to the listed 77 mm (3.03 in) through a 91 mm (3.58 in) spindle bore
- Mazak's long boring bar stocker figures name only the e-500H, e-670H and e-800H

Frequently Asked Questions
01
A second spindle. The table lists a sub spindle described as equivalent to the main spindle, and C-axis rotation is given as 360° continuous on both spindles. On Mazak's INTEGREX e-H model list the -S models, the e-500H-S and e-670H-S, are marked Second Spindle.
02
Mazak's series list names the INTEGREX e-500H, e-500H-S, e-670H, e-670H-S and e-800H. The e-420H-S is not on that list, so ask Mazak which current model corresponds to it before planning around the listed figures on this page.
03
The main spindle is listed at 4,000 rpm with 30 hp (22 kW) continuous and 40 hp (30 kW) on the 30-minute rating, and the sub spindle is described as equivalent to it. The milling spindle is listed at 12,000 rpm and 22 kW (29.3 hp), with no duty rating stated. Bar capacity is listed at 77 mm (3.03 in) through a 91 mm (3.58 in) bore.
04
Mazak describes a built-in motor spindle, temperature-controlled cooling oil circulated around the spindle bearings and headstock, and a milling spindle with an automatic tool changer that uses the same tool vertically, horizontally or at any angle. The series runs the MAZATROL SmoothAi control, and Mazak offers a long boring bar system for deep machining of inner diameters on large workpieces.
