How much does the GF Mikron HPM 400U cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from GF Machining Solutions. Configuration moves it a long way.
Overview
The Mikron HPM 400U is a 5-axis machining center with 500 × 450 × 400 mm of travel, a 20,000 RPM HSK-A63 spindle and a Ø 400 mm trunnion table. It does not appear in GF Machining Solutions' current Mikron lineup, so this page is mainly for anyone assessing a used machine.
The spindle is listed at 35 kW (47 hp) and 120 Nm (88.5 ft-lb), enough for steady roughing in steel as well as finishing at speed. The magazine holds 30 tools, with 60 listed as an option, so check which one a given machine actually carries. Rapid traverse is 45 m/min.
The trunnion swivels from -30° to +120° on the A-axis and the C-axis turns 360° continuously. Work weight is limited to 250 kg. The machine sits on a polymer granite base and weighs 9,000 kg.
The current Mikron MILL E 500 U has the same 500 / 450 / 400 mm travels on a T-slot table Ø500 mm with a 300 / 200 kg load, which makes it the natural new-machine reference. The listed control for the HPM 400U is a Heidenhain TNC 7; on a used machine, confirm the control generation actually fitted, together with the spindle hours and the state of the trunnion.

Frequently Asked Questions
01
It does not appear in GF Machining Solutions' current Mikron lineup. The closest current machine in size is the Mikron MILL E 500 U, which has the same 500 / 450 / 400 mm travels on a T-slot table Ø500 mm with a 300 / 200 kg load.
02
The listed spindle runs to 20,000 RPM with an HSK-A63 interface, 35 kW (47 hp) and 120 Nm (88.5 ft-lb). On a used machine, ask for the spindle hours and any rebuild history before agreeing a deal.
03
Work weight is listed at 250 kg on a Ø 400 mm trunnion table. The A-axis swivels from -30° to +120° and the C-axis rotates 360° continuously, so the fixture plus part also has to clear the trunnion through that swivel.
04
The control fitted (the table lists a Heidenhain TNC 7), whether the magazine is the 30-tool standard or the 60-tool option, the spindle condition, and the trunnion axes. The machine weighs 9,000 kg, so plan the move and foundation too.
