Overview
The Parpas HS 70 is a high-speed precision horizontal machining center designed for demanding five-face and four-axis machining of complex aluminum, titanium, and steel components. Parpas, an Italian precision machine tool builder with roots in the production of large jig boring machines and horizontal machining centers, developed the HS 70 to bridge the gap between conventional HMCs and the higher spindle speeds and thermal precision required by aerospace and precision engineering customers.
The HS 70 features a 700 mm (27.6 in) pallet size with a maximum workpiece envelope of 800 mm (31.5 in) diameter by 800 mm (31.5 in) height. The main spindle achieves 12,000 RPM at 35 kW (46.9 HP) through an HSK-A63 tool interface, with an optional 18,000 RPM electro-spindle for high-speed aluminum finishing. Axis travels are 800 mm in X, 700 mm in Y, and 700 mm in Z, with rapid traverse rates of 50 m/min (1,969 IPM) on all linear axes. The CNC B-axis rotary table provides 4-axis simultaneous interpolation and full 360-degree continuous rotation at 50 RPM for high-speed indexing and contouring.
Parpas integrates a comprehensive thermal compensation system monitoring the spindle, column, and bed temperatures in real time, correcting the axis position based on a network of embedded sensors. The machine is available with a Siemens SINUMERIK 840D sl or Heidenhain iTNC 640 control. Pallet changing is automated through a 2-station APC (Automatic Pallet Changer) for continuous production, with optional expansion to 4 or 6 pallet FMS configurations. The HS 70's high-damping polymer-concrete bed and precision box guideways on all axes deliver positioning accuracy of ±0.004 mm (±0.00016 in) and repeatability of ±0.002 mm (±0.000079 in).
Parpas HS 70 pricing typically ranges from $700,000 to $1,200,000 depending on spindle configuration, pallet system, and automation options.

Strengths & Limitations
Strengths
- High positioning accuracy of ±0.004 mm and repeatability of ±0.002 mm make the HS 70 suitable for precision aerospace and optical component machining that standard HMCs cannot achieve
- 50 m/min rapid traverse rates on all axes minimize non-cutting time on complex multi-operation programs with many tool changes and repositioning moves
- Optional 18,000 RPM electro-spindle enables high-speed finish machining of aluminum aerospace structures with excellent surface quality and reduced cycle times
- Polymer-concrete bed construction provides high vibration damping compared to cast iron, improving surface finish quality on deep-pocket and thin-wall features
Limitations
- 700 mm pallet size limits the machine to medium-size components; shops requiring 800-1,000 mm pallet capacity must consider larger HMC platforms
- Italian origin means North American service support may be less comprehensive than Japanese or German HMC brands with larger installed bases
- Premium pricing relative to Japanese HMCs of similar size reflects precision German/Italian build quality but increases capital investment

Frequently Asked Questions
01
The HS 70 achieves ±0.004 mm positioning accuracy through a combination of high-precision ball screws with direct-drive torque motors on rotary axes, a comprehensive thermal compensation network with 20+ temperature sensors monitoring the machine structure in real time, and a polymer-concrete bed that reduces thermal and dynamic distortion compared to cast iron. The Siemens 840D sl or Heidenhain iTNC 640 control applies compensation values continuously to maintain accuracy during long production runs.
02
The 18,000 RPM electro-spindle is designed for high-speed finish machining of aluminum aerospace structures, thin-wall pockets, and complex contoured surfaces where high surface speed is needed to achieve the required surface quality and tool life. At 18,000 RPM with HSK-A63 tooling, the HS 70 can achieve surface speeds on aluminum that approach or match dedicated high-speed machining centers, making it versatile across both steel/titanium roughing and aluminum finishing work.
03
Yes. The HS 70 is available with a 2-station APC as standard and can be expanded to 4 or 6 pallet FMS configurations with a linear pallet pool and automatic workpiece transfer. Parpas offers FMS integration packages with centralized control software for managing pallet scheduling, tool management, and production monitoring across multi-machine cells.
04
The HS 70 is offered with either a Siemens SINUMERIK 840D sl or a Heidenhain iTNC 640, both of which provide 4-axis simultaneous interpolation and full 5-axis optional capability. Aerospace customers frequently specify the Heidenhain iTNC 640 for its high-speed look-ahead and surface finish optimization features, while general engineering and automotive shops often prefer the Siemens 840D for its compatibility with existing DNC infrastructure.
05
Parpas is an Italian machine tool manufacturer based in Quinto di Treviso, near Venice in the Veneto region of northeast Italy. The company has been producing precision boring mills and horizontal machining centers since the 1960s and is known for its high-accuracy large-format machines. Parpas is part of a broader Italian precision machine tool heritage including brands like Rambaudi and FPT Industrie. The HS 70 and other Parpas machines are designed and manufactured entirely in Italy.
