How much does the Starrag Heckert H70 cost?
Estimated price range
Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Starrag. Configuration moves it a long way.
Overview
The Starrag Heckert H70 is a horizontal machining center with a 700 x 700 mm (27.6 x 27.6 in) pallet, listed travels of 950 x 900 x 1,000 mm (37.4 x 35.4 x 39.4 in) and a 12,000 rpm HSK-A63 spindle rated 42 kW (56 hp) and 420 Nm (310 ft-lb). The pallet takes 1,400 kg (3,086 lb).
It is easiest to place by its neighbours. The Heckert H65 is the same kind of machine one step down: a 630 x 630 mm (24.8 x 24.8 in) pallet for 1,200 kg (2,646 lb), 37 kW (50 hp) and 370 Nm (273 ft-lb). Moving to the H70 from the Heckert H65 adds about 14% in power and torque and about 17% in pallet load, while spindle speed, taper, rapids and Z travel stay the same.
One step up, the Heckert H75 changes character: it is listed with an HSK-A100 spindle and 50 kW (67 hp), a 750 x 750 mm (29.5 x 29.5 in) pallet and 50 m/min (1,969 ipm) rapids. Of the three, the H70 is the largest pallet that keeps the HSK-A63 interface and 60 m/min (2,362 ipm) rapids. If the tooling is already HSK-A63 and the parts have outgrown the pallet of the Heckert H65, that is the case for this model.
The listed figures also give 0.001 deg B-axis indexing through a worm gear, two pallets expandable via a pallet pool, 60 tools expandable to 180+, positioning accuracy of ±0.005 mm with ±0.003 mm repeatability, a Siemens SINUMERIK 840D sl control and a machine weight of 18,000 kg (39,683 lb).

Strengths & Limitations
Strengths
- 420 Nm (310 ft-lb) and 42 kW (56 hp), about 14% more than the Heckert H65 in both
- 700 x 700 mm (27.6 x 27.6 in) pallet carrying 1,400 kg (3,086 lb)
- Keeps 60 m/min (2,362 ipm) rapids and 12,000 rpm on the larger pallet
- Travels of 950 x 900 x 1,000 mm (37.4 x 35.4 x 39.4 in)
- Pallet pool and magazine expansion to 180+ tools are listed
Limitations
- HSK-A63 only in the listed figures; the HSK-A100 interface starts with the Heckert H75
- The Heckert H65 offers the same Z travel, spindle speed and rapids, so the gain over it is confined to pallet size, load and spindle rating
- The standard magazine is 60 tools; more requires the expansion
- Machine weight of 18,000 kg (39,683 lb) has to be allowed for in floor loading and rigging

Frequently Asked Questions
01
Pallet, load and spindle rating. The Heckert H65 has a 630 x 630 mm (24.8 x 24.8 in) pallet for 1,200 kg (2,646 lb) with 37 kW (50 hp) and 370 Nm (273 ft-lb). The H70 has a 700 x 700 mm (27.6 x 27.6 in) pallet for 1,400 kg (3,086 lb) with 42 kW (56 hp) and 420 Nm (310 ft-lb). Both are listed at 12,000 rpm, HSK-A63 and 60 m/min (2,362 ipm).
02
It depends on the tooling. The Heckert H75 is listed with an HSK-A100 spindle, 50 kW (67 hp), a 750 x 750 mm (29.5 x 29.5 in) pallet and 50 m/min (1,969 ipm) rapids. The H70 stays with HSK-A63, 42 kW (56 hp) and 60 m/min (2,362 ipm), which favours lighter tools and faster positioning.
03
The listed travels are 950 mm (37.4 in) in X, 900 mm (35.4 in) in Y and 1,000 mm (39.4 in) in Z. Each is longer than the 700 mm (27.6 in) pallet edge, so the spindle can reach beyond the pallet on all sides.
04
Positioning accuracy is listed as ±0.005 mm and repeatability as ±0.003 mm, with a B axis that indexes in 0.001 deg steps through a worm gear. The control is Siemens SINUMERIK 840D sl.
