How much does the Starrag Heckert H75 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 H75 is listed as an HSK-A100 horizontal machining center that still reaches 12,000 rpm, with 50 kW (67 hp) of continuous spindle power. Its pallet is 750 x 750 mm (29.5 x 29.5 in) and the travels are 1,000 x 900 x 1,000 mm (39.4 x 35.4 x 39.4 in).
The listed workpiece limits are 1,500 kg (3,307 lb), 1,000 mm (39.4 in) in diameter and 1,200 mm (47.2 in) in height. Two things follow. The diameter limit is a third larger than the pallet edge, so fixtures may overhang the pallet as long as they clear when the B axis turns. And the height limit is a third greater than the 900 mm (35.4 in) Y travel, so a part of full height fits in the machine but cannot be reached over its whole height by the spindle; plan the features near the top and bottom of tall parts accordingly.
An HSK-A100 interface at 12,000 rpm lets one spindle hold large face mills and boring bars and still run small cutters at speed. No torque figure is listed, so the low-speed cutting capacity has to be confirmed. Rapid traverse is 50 m/min (1,969 ipm). The Heckert X80 is listed with the same interface, 50 kW (67 hp) and 50 m/min (1,969 ipm), plus an 80-tool magazine expandable to 300, where the H75 holds 60 tools as standard with 120 or 240 optional.
The pallet changer is listed as 2-pallet standard and FMS-ready. Positioning accuracy is ±0.006 mm (±0.00024 in), repeatability ±0.003 mm (±0.00012 in), the B axis has 0.001° resolution, and the control is Siemens SINUMERIK 840D sl.

Strengths & Limitations
Strengths
- HSK-A100 spindle that reaches 12,000 rpm with 50 kW (67 hp) continuous
- Workpieces up to 1,500 kg (3,307 lb), 1,000 mm (39.4 in) in diameter and 1,200 mm (47.2 in) tall
- X and Z travels of 1,000 mm (39.4 in) over a 750 x 750 mm (29.5 x 29.5 in) pallet
- Tool magazine of 60 as standard, with 120 or 240 optional
- 2-pallet changer as standard, listed as FMS-ready
Limitations
- Y travel of 900 mm (35.4 in) is less than the 1,200 mm (47.2 in) maximum workpiece height
- No spindle torque is listed, so heavy low-speed cutting capacity is unconfirmed
- The 120 and 240 tool magazines are options; 60 tools is the standard
- Listed positioning accuracy is ±0.006 mm (±0.00024 in); tolerances near that figure need the measuring standard confirmed

Frequently Asked Questions
01
The listed limits are 1,500 kg (3,307 lb) in weight, 1,000 mm (39.4 in) in diameter and 1,200 mm (47.2 in) in height, on a 750 x 750 mm (29.5 x 29.5 in) pallet. Y travel is 900 mm (35.4 in), so the spindle does not cover the full height of the tallest part.
02
An HSK-A100 spindle with a maximum of 12,000 rpm and 50 kW (67 hp) continuous power. Torque is not among the listed figures; ask for the torque curve if the work includes heavy roughing at low speed.
03
60 tools as standard. Magazines of 120 or 240 tools are listed as options, so the larger capacities have to be ordered and are not part of the base machine.
04
The pallet changer is listed as 2-pallet standard and FMS-ready, which means two pallets come with the machine and it is prepared for connection to a flexible manufacturing system. The control is Siemens SINUMERIK 840D sl.
05
Listed positioning accuracy is ±0.006 mm (±0.00024 in) and repeatability is ±0.003 mm (±0.00012 in). The B axis is listed with 0.001° resolution.
