Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from GF Machining Solutions. Configuration moves it a long way.
Overview
The Mikron MILL S 500 Graphite is listed as a graphite-milling variant of the MILL S 500, with 500 x 400 x 400 mm of travel, a 600 x 500 mm table for 300 kg and a 42,000 RPM HSK-E32 Step-Tec spindle at 13 kW. GF Machining Solutions does not show a graphite version of the MILL S 500 in its current lineup, and this table has not been matched to a GF page.
That matters here more than usual, because the listed figures do not agree with the current machine of the same name. GF's current Mikron MILL S 500 has 500 x 450 x 360 mm of travel, a 590 x 450 mm table for 200 kg, a machine weight of 6,800 kg and Heidenhain TNC 7 control. This page lists 400 mm of Y, 400 mm of Z, a 300 kg table, 8,500 kg and a Heidenhain TNC 640. Either it describes an earlier build, or the figures are wrong; a buyer should measure and weigh against the machine itself.
As listed, the graphite equipment is complete: dry machining with no coolant, a high-flow HEPA-grade closed-loop extraction system, and sealed linear guides, ballscrews, drives and electrical cabinet. Rapid traverse is 60 m/min, the magazine holds 20 tools expandable to 40, and positioning accuracy is given as 0.003 mm.
On the listed 600 x 500 mm table, several electrode blanks can be fixtured side by side, and with the magazine expanded to 40 tools a whole electrode set can run as one unattended batch.

Strengths & Limitations
Strengths
- Listed 600 x 500 mm table for 300 kg, room for several electrode blanks
- Dry machining with a high-flow HEPA-grade closed-loop extraction system
- Sealed linear guides, ballscrews, drives and electrical cabinet against graphite dust
- 42,000 RPM Step-Tec spindle and 60 m/min rapid traverse
Limitations
- Listed figures conflict with GF's current Mikron MILL S 500 (500 x 450 x 360 mm, 200 kg table, 6,800 kg)
- 13 kW on an HSK-E32 interface restricts the machine to small tools
- No coolant listed, so wet machining of copper or steel is excluded

Frequently Asked Questions
01
Not on the listed figures. The current Mikron MILL S 500 has 500 x 450 x 360 mm of travel, a 590 x 450 mm table for 200 kg and weighs 6,800 kg. This page lists 500 x 400 x 400 mm, a 600 x 500 mm table for 300 kg and 8,500 kg. Measure any machine offered under this name.
02
The table lists a high-flow HEPA-grade closed-loop extraction system and fully sealed linear guides, ballscrews, drives and electrical cabinet. It cuts dry, with no coolant.
03
A Step-Tec spindle listed at 42,000 RPM and 13 kW with an HSK-E32 interface. The magazine holds 20 tools, expandable to 40, so a used machine may have either.
04
The table lists a Heidenhain TNC 640. GF's current Mikron MILL S 500 is offered with Heidenhain TNC 7, so confirm the control on any machine offered and whether your CAM post-processor supports it.
