How much does the Starrag SRM 500 cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from Starrag. Configuration moves it a long way.
Overview
The Starrag SRM 500 is a 5-axis machining center for rotational parts up to 500 mm (19.7 in) in diameter and 150 kg (330 lb), with a Starrag Blisk machining process package among its listed features. The figures on this page are the listed ones only. They have not been matched to a Starrag page for the SRM 500, so confirm them before planning work around them.
The envelope is defined by the part, not by linear travels: no X, Y or Z travel is listed. What the table gives instead is the rotary geometry. The A axis swings ±110° and the C axis rotates 360° continuously, each with a listed accuracy of ±3 arcseconds. On a bladed disc the cutter has to reach between neighbouring blades at a steep angle and come back to the same angular position blade after blade, so rotary accuracy counts as much as linear accuracy. The linear figures are ±0.005 mm (±0.0002 in) positioning and ±0.002 mm (±0.00008 in) repeatability.
The spindle is listed at 18,000 RPM with an HSK-A63 taper and 35 kW (47 HP) continuous. Linear rapid traverse is 30 m/min (1,181 IPM). The magazine holds 40 tools as standard, with 80 optional, and the control is a Siemens SINUMERIK 840D sl. Neither a torque figure nor a machine weight is listed.

Frequently Asked Questions
01
The listed maximum workpiece diameter is 500 mm (19.7 in) and the maximum workpiece weight is 150 kg (330 lb). No linear travels are listed, so the usable part height has to be confirmed for the individual machine.
02
Both the A axis and the C axis are listed at ±3 arcseconds. The A axis has a range of ±110° and the C axis rotates 360° continuously. Linear positioning accuracy is listed at ±0.005 mm (±0.0002 in), with repeatability of ±0.002 mm (±0.00008 in).
03
An 18,000 RPM spindle with an HSK-A63 taper and 35 kW (47 HP) continuous. There is no torque figure in the table, so ask for the torque curve if the work includes roughing from solid.
04
40 tools as standard, with 80 optional. Linear rapid traverse is listed at 30 m/min (1,181 IPM), the control is a Siemens SINUMERIK 840D sl, and a Starrag Blisk machining process package is listed.
