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 MILL E 500 U is the smaller of GF Machining Solutions' two MILL E U machines: a cast iron C-frame 5-axis machining center with 500 × 450 × 400 mm of travel, a 20,000 rpm HSK-A63 spindle rated 36 kW and 120 Nm, and a T-slot table Ø500 mm. GF pitches it at job shops and part producers, and the table reads that way: general 5-axis work in a range of materials rather than one specialised job.

The swivel range of -65° / +120° is the figure GF highlights. Tilting as far as +120° in one direction lets the spindle reach under overhangs and into the back faces of a part without a second setup. Both rotary axes use direct torque drives with no mechanical transmission, and GF quotes repeatability within 10 µm for them. Swivel speed is 32 rpm and rotary speed 112 rpm; the linear feed rate is 30 m/min.

The spindle uses GF's OptiCool design to cool the front bearing area, plus a heat barrier cooling loop between the motor and the spindle nose. With 120 Nm on an HSK-A63 taper, roughing and finishing can both run on this machine.

Workholding options are wide: besides the T-slot table, the table lists System 3R Dynafix 350x350, Erowa UPC 320x320 mm, System 3R Delphin 400x400 and Erowa MTS 400x400 mm. Load is listed as 300 / 200 kg without saying which figure applies to which setup, so ask GF before planning a heavy fixture. Magazines hold 30, 60 or 170 tools, and the control is a Heidenhain TNC 640.

The Mikron MILL E 700 U is the larger model on the same page, with 700 × 600 × 500 mm of travel, a T-slot table Ø630 mm and a 450 kg load.

Strengths & Limitations

Strengths

Swivel range of -65° / +120° reaches undercuts and back faces in one setup
Direct torque drives on both rotary axes, with repeatability within 10 µm quoted by GF
20,000 rpm HSK-A63 spindle rated 36 kW and 120 Nm
T-slot table Ø500 mm or Dynafix, Erowa UPC, Delphin and Erowa MTS pallet systems
Tool magazines of 30, 60 or 170 pockets

Limitations

Load is listed as 300 / 200 kg without saying which figure goes with which setup
Linear feed rate of 30 m/min
Rotary axes are listed at 32 rpm swivel and 112 rpm rotary, too slow for turning work
A single control is listed, the Heidenhain TNC 640

Best For

Job-shop 5-axis parts within 500 × 450 × 400 mm Parts with undercuts that need up to +120° of tilt Steel and aluminium parts roughed and finished at up to 36 kW Shops standardised on Erowa or System 3R pallets

Frequently Asked Questions

01 What is the swivel range of the MILL E 500 U?

-65° / +120°, with n x 360° on the rotary axis. GF names this range as a highlight of the MILL E 500/700 U. Both axes are direct torque drives, at 32 rpm swivel and 112 rpm rotary.

02 How heavy a part can the MILL E 500 U carry?

The load row reads 300 / 200 kg. It does not say which figure belongs to the T-slot table and which to the pallet systems, so confirm the limit for your clamping setup with GF before ordering.

03 How does the MILL E 500 U differ from the MILL E 700 U?

The Mikron MILL E 700 U has 700 × 600 × 500 mm of travel, a T-slot table Ø630 mm and a 450 kg load. The MILL E 500 U has 500 × 450 × 400 mm and a T-slot table Ø500 mm. Swivel range, feed rates, magazine sizes and the TNC 640 control are the same.

04 What spindle does the MILL E 500 U use?

A STEP TEC spindle at 20,000 rpm with an HSK-A63 interface, rated 36 kW and 120 Nm. OptiCool cooling at the front bearings and a heat barrier loop keep motor heat away from the spindle nose.

05 Can the MILL E 500 U be automated?

GF lists the machine as automation ready and says it can grow from a single machine to a fully automated cell. The table names System 3R Dynafix, Erowa UPC, System 3R Delphin and Erowa MTS clamping, and a 170-pocket magazine is available.
