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 H55 is a compact horizontal machining center on a 500 x 500 mm (19.7 x 19.7 in) pallet. The listed figures give it travels of 750 x 700 x 750 mm (29.5 x 27.6 x 29.5 in), an HSK-A63 spindle running to 12,000 rpm with 35 kW (47 hp) continuous, and 60 m/min (2,362 ipm) rapids.
Three items are choices. An 18,000 rpm spindle is listed as an option to the 12,000 rpm standard, which matters for small cutters in aluminium. The magazine holds 60 tools as standard, with 120 or 240 optional. And the control is listed as Siemens SINUMERIK 840D sl or Fanuc 31i-B, so the machine can follow whichever of the two a shop already programs.
X travel is 50% wider than the pallet, so the spindle can reach past both edges of a fixture, and the 700 kg (1,543 lb) workpiece limit has to be checked against part and fixture together. The pallet changer is listed as 2-pallet standard and FMS-ready, meaning it is prepared for connection to a pallet system. Positioning accuracy is listed as ±0.005 mm (±0.0002 in) with ±0.003 mm (±0.00012 in) repeatability, and the B axis indexes at 0.001° resolution. No spindle torque or machine weight appears among the listed figures.

Strengths & Limitations
Strengths
- Spindle speed of 12,000 rpm as standard, with 18,000 rpm listed as an option
- 60 m/min (2,362 ipm) rapid traverse on travels of 750 x 700 x 750 mm (29.5 x 27.6 x 29.5 in)
- Magazine of 60 tools as standard, with 120 or 240 optional
- Control listed as Siemens SINUMERIK 840D sl or Fanuc 31i-B
- 2-pallet changer as standard, listed as FMS-ready
- Listed positioning accuracy of ±0.005 mm (±0.0002 in) and repeatability of ±0.003 mm (±0.00012 in)
Limitations
- The 18,000 rpm spindle and the 120 and 240 tool magazines are options, not part of the standard machine
- Workpiece weight is limited to 700 kg (1,543 lb)
- No spindle torque is listed, so heavy roughing capacity cannot be judged from the 35 kW (47 hp) rating alone
- HSK-A63 limits tool diameter and length compared with HSK-A100 machines such as the Heckert X80

Frequently Asked Questions
01
12,000 rpm is the standard figure and 18,000 rpm is listed as an option. The spindle takes HSK-A63 tooling and is rated 35 kW (47 hp) continuous. Torque is not among the listed figures.
02
The pallet is 500 x 500 mm (19.7 x 19.7 in) and the listed maximum workpiece weight is 700 kg (1,543 lb). Travels are 750 mm (29.5 in) in X, 700 mm (27.6 in) in Y and 750 mm (29.5 in) in Z, so the axes reach beyond the pallet in every direction.
03
Two: Siemens SINUMERIK 840D sl and Fanuc 31i-B. The listed figures do not say which is standard, so name the control when the machine is specified, and check that options such as the 18,000 rpm spindle are available with it.
04
The magazine holds 60 tools as standard, with 120 or 240 listed as options. The pallet changer is 2-pallet as standard and is listed as FMS-ready, so the machine can start as a stand-alone cell and be tied into a pallet system later.
05
The listed positioning accuracy is ±0.005 mm (±0.0002 in) and repeatability is ±0.003 mm (±0.00012 in). The B axis is listed with 0.001° resolution. The figures do not state the measuring standard behind them, so ask for it if the tolerance on the part is close to these values.
