HTG 310: Compact Production Cylindrical grinding machine for workpieces up to 400 mm

The HTG 310 is specifically designed for the precise machining of smaller and compact workpieces. As a compact production cylindrical grinding machine, it is ideal for applications that require high accuracy in limited installation space. Thanks to its robust machine structure and high-quality guideways, it enables smooth machining with high dimensional accuracy – even on demanding geometries.

Workhead
  • With MT5 (roller-bearing mounted)
  • With MT4 (hydrodynamic bearings): very accurate concentricity ≤ 0,001 mm
  • Alternatively with MT4 high-precision: high-precision concentricity ≤ 0,0005 mm
Hydrodynamic wheelhead
  • Good damping properties
  • Self-centering with high-precision concentricity
  • Long service life
Slide guideways
  • High process stability thanks to high-precision V and flat guideways
Cast iron machine bed
  • Distortion-free, thermally stable and vibration-damping
  • Cubic, heavily ribbed
Tailstock MT3
  • Adjustable quill pressure
  • Manual or automatic operation (optional)
  • Taper correction +/- 0,02 mm (optional)

The heavily ribbed machine base made of high-quality, multiply stress-relief annealed cast iron ensures maximum rigidity and damping. The entire grinding cycle can be preset, thus simplifying single-piece and small batch production.

The good accessibility to all functional areas shortens changeover times and facilitates maintenance. A large selection of application-oriented accessories expands the range of uses and enables the machining of even complex workpieces.
