Overview

The DMG Mori HSC 20 linear is a high-speed 5-axis machining center designed for ultra-precision work on small parts. With travel of just 200 x 220 x 280 mm (7.9 x 8.7 x 11.0 in), this is not a general-purpose machine — it is a precision instrument built for micro-machining, dental restorations, watch components, medical implants, and graphite electrodes where surface finish and accuracy matter more than anything else.

Linear motor drives on all three linear axes eliminate ball screw backlash and deliver acceleration exceeding 2G. That translates to extremely fast repositioning between cuts, keeping non-cutting time to a minimum on small parts with many features. The linear motors also provide exceptional following accuracy during high-speed contouring, which is critical for achieving mirror-like surface finishes on complex 3D geometries.

The spindle options range from 42,000 to 60,000 RPM, all using HSK-E32 or HSK-E40 tapers. These are not conventional milling spindles — they are precision grinding-class spindles designed for micro-tools and ultra-high surface speed cutting. Water-cooled variants with active cooling maintain thermal stability during extended production runs.

The NC swivel/rotary table provides A-axis tilt from -15 to +130 degrees and 360-degree continuous C-axis rotation. For 5-axis work, the table handles 15 kg (33 lb) on a 200 mm diameter clamping surface. A rigid table option at 370 x 320 mm handles 100 kg for 3-axis positioning work.

The integrated linear magazine (PH 10/100 system) supports up to 99 pallet places with maximum 10 kg handling weight, enabling automated production of diverse small parts. The control is Siemens-based.

The HSC 20 linear competes with machines like the Kern Micro, Roders RXP 200, and Makino iQ300. It occupies a niche where speed, accuracy, and surface finish at miniature scales define the application. Specs sourced from DMG Mori published data.

Strengths & Limitations

Strengths

Linear motor drives on all axes deliver >2G acceleration with zero backlash for exceptional contouring accuracy
Spindle speeds from 42,000 to 60,000 RPM enable micro-machining with sub-millimeter tools at optimal surface speeds
Integrated pallet system with up to 99 positions enables automated lights-out production of diverse small parts
HSK-E32/E40 precision spindle tapers provide the concentricity needed for micro-tool applications
Water-cooled spindle options maintain thermal stability during extended production runs
A-axis range of -15 to +130 degrees provides good access for 5-axis micro-machining
Linear motors eliminate ball screw wear for consistent accuracy over the machine lifetime

Limitations

200 x 220 x 280 mm travel limits this to very small parts; it cannot handle anything beyond miniature components
15 kg 5-axis table load is extremely restrictive; only the lightest workpieces and fixtures fit
Spindle speeds above 40,000 RPM require specialized tooling and holders that are expensive and fragile
Starting at $350K for a machine with this tiny work envelope requires high-value applications to justify the investment
HSK-E32/E40 tooling ecosystem is much smaller and more expensive than standard HSK-A63 or BT40

Best For

Dental restoration manufacturers producing crowns, bridges, and implant abutments Watch component manufacturers requiring ultra-precision 5-axis machining of miniature parts Medical implant makers cutting small titanium and cobalt-chrome components Graphite electrode manufacturers needing mirror surface finish on complex EDM electrodes Micro-mold shops cutting tiny cavity inserts with sub-micron surface finish requirements R&D labs machining precision micro-components for optics, sensors, and MEMS applications

Frequently Asked Questions

01 What does a DMG Mori HSC 20 linear cost?

New HSC 20 linear machines price between $350,000 and $550,000 depending on spindle speed selection, pallet system configuration, and automation level. The 60,000 RPM spindle and full 99-pallet system push toward the upper end.

02 Why linear motors instead of ball screws?

Linear motors eliminate the mechanical backlash and friction inherent in ball screw drives. At the micro-machining level, even 1-2 microns of backlash can ruin a part. Linear motors also provide >2G acceleration, which drastically reduces non-cutting time on small parts with many features — a critical factor when cycle times on micro-parts can be dominated by rapid moves.

03 What surface finish can the HSC 20 linear achieve?

With the right tooling and parameters, the HSC 20 linear achieves surface finishes below Ra 0.1 µm on materials like graphite, aluminum, and hardened steel. The linear motor drives and high-speed spindles provide the dynamic accuracy needed for mirror-finish quality on complex 3D surfaces.

04 Is this machine suitable for hard milling?

Yes. With the appropriate spindle (typically 42,000-50,000 RPM range) and micro-tools, the HSC 20 linear handles hardened steel up to 62 HRC for micro-mold and die applications. The linear motor dynamics allow high feed rates with small stepovers for efficient hard milling.

05 How does the pallet system work?

The integrated PH 10/100 linear magazine holds up to 99 pallets with automated loading/unloading. Each pallet handles up to 10 kg. The system enables lights-out production of diverse small parts by automatically cycling through different workpieces with different programs.
