HAAS ST-25 CAPABILITIES

Machine Overview

The HAAS ST-25 is a versatile, high-performance CNC turning center that excels at precision parts production. With a robust spindle, programmable tooling, and excellent repeatability, it handles a wide range of materials and part complexities — ideal for prototyping, short-run, and production environments.

Materials Machined

  • Aluminum and aluminum alloys

  • Carbon and stainless steels

  • Brass, bronze, copper

  • Plastics and composites

  • Titanium and exotic alloys
    (with proper tooling & feeds)

 

Typical Applications

  • Precision turned components

  • Complex shaft work

  • Short-run and production job lots

  • High-accuracy fittings, bushings, spacers

  • Cross-hole drilling and multi-operation parts
    (with live tooling)

 

Work Envelope / Physical Dimensions

  • Swing Over Bed: 19.0 in (483 mm)

  • Maximum Turning Diameter: ~13.0 in (330 mm)

  • Maximum Turning Length: ~16.0 in (406 mm)

  • Chuck Size: 10.0 in (254 mm) standard
    (optional sizes available)

  • Maximum Bar Capacity

  • Spindle Bore: ~3.0 in (approx.)

  • Precision bearings and optional spindle cooling available

 

Feed & Rapid Movements

  • Rapid Traverse (X & Z): 300–500 IPM

  • High-speed cutting capable

  • Smooth acceleration for surface finish and cycle time optimization

 

Tooling & Turret

  • Tooling System: Programmable multi-station turret

  • Station count typically 8–12 (model/config dependent)

  • Optional Live Tooling: Available for milling, drilling, tapping in one setup

  • Tool stations support broad tooling range (turning, grooving, boring, etc.)

 

Control & Accuracy

  • CNC Control: HAAS Control with conversational programming

  • Repeatability: ±0.0004 in (typical)

  • Part Accuracy: ±0.001 in (depends on tooling/material)

  • Programmable tool offsets and thermal compensation
