Overview
The GF Machining MIKRON MILL P 900 is the larger-envelope member of the MILL P precision milling series, designed for mold, die, and toolmaking shops that need the same sub-micron surface finish quality as the MILL P 500 but with substantially more working volume and table capacity.
The MILL P 900 provides X/Y/Z travels of 900 x 600 x 450 mm (35.4 x 23.6 x 17.7 in) on a T-slot table measuring 1,000 x 600 mm (39.4 x 23.6 in) with a substantial 1,000 kg (2,205 lb) load capacity. This work envelope handles medium-to-large injection mold cavity blocks, die inserts, and fixture plates.
The standard spindle configuration is a 20,000 RPM Step-Tec unit with HSK-A63 taper and 120 Nm of torque, making it a genuine dual-purpose machine. GF also offers a 36,000 RPM HSK-E50 spindle option for maximum surface finish quality.
GF Intelligent Thermal Control (ITC) is standard, continuously compensating for thermal drift during extended machining cycles. The 30-pocket tool magazine (expandable to 60) and System 3R Delphin pallet automation enable unattended production. Pricing ranges from approximately $350,000 to $550,000.

Strengths & Limitations
Strengths
- 900 x 600 mm X/Y travel with 1,000 kg table capacity handles medium-to-large mold blocks and die inserts
- Dual spindle availability: 20,000 RPM / 120 Nm HSK-A63 for balanced work, or 36,000 RPM HSK-E50 for maximum finish quality
- 120 Nm spindle torque at 20,000 RPM provides genuine semi-roughing capability in hardened tool steel
- Intelligent Thermal Control (ITC) maintains dimensional accuracy across extended machining cycles
- System 3R Delphin pallet automation and WorkPartner compatibility enable unattended overnight production
- High dynamic stiffness maintains surface finish quality at aggressive cutting parameters
Limitations
- 30 m/min feed rate is conservative compared to dedicated high-speed machines
- At $350K-$550K, requires a clear precision mold or die workload to justify the premium
- 450 mm Z travel may be limiting for very deep mold cavities
- The 36,000 RPM HSK-E50 spindle option adds significant cost and requires separate toolholders

Frequently Asked Questions
01
Typically $350,000-$550,000 new. Base machine with 20K RPM HSK-A63 starts near $350K; 36K spindle, 60-pocket mag, and pallet automation push toward $550K.
02
Larger travels (900x600x450 vs 500x450x350mm), higher capacity (1,000 vs 300kg). P 500 runs at 42K RPM for max finish on small parts; P 900 is more versatile.
03
20K RPM HSK-A63 with 120 Nm for most shops. 36K RPM option for shops where surface finish is the primary differentiator.
04
Hardened tool steel (62 HRC), pre-hardened mold steel (P20, H13, S7), aluminum, graphite, copper electrodes, stainless, engineering plastics.
