Stahli 2-Wheel Flat Honing & Fine Grinding

FH3 505 - 805

Flat Honing With Super Abrasive Wheels

Introduction

Where precision meets throughput rates!

Historically fine grinding could not match throughput rates produced by traditional double disc grinding machines.  With the invention of the FH3, this is no longer the case!

   Load/Unload Times
DLM 505                                      1.5-2 Minutes
DLM 705                                       2-3 Minutes
FH3 505/805                               10 Seconds

With the improvement of load/unload times, the FH3 can match the throughput rates of a through-feed double disc grinding machine while still maintaining the tolerances of the DLM models.  This will truly be a revolutionary design in the industrial field.

ZL 501 GIII

Flat Honing With Super Abrasive Wheels

Introduction

Pioneers of fine grinding process on two-wheel machines are the Duomat and ZL models of the Hahn & Kolb series. They have been advanced by the Stahli group and represent thus a successful synthesis of the combined know-how. In the past over 2000 machines from these series were sold worldwide. The users now are being supported by the Stahli group and benefit from the latest technology.

With the new ZL 501 GIII we kept the basic principle of the vibrationless and rigid cast design and made it even more rigid and heavy to consider todays driving power requirements. To pivoted swiveling arm is still supported on a centre beam and the work force is hydraulically applied. Additional improvements and the touch-panel with extended machine functions complete the complete concept.

  • Sturdy Cast design
  • Sensitive loading capability
  • High repeatability
  • Safety guard for work zones
  • Working wheels diameter up to 540mm
  • Variable planetary drive equipment
  • Computer-aided measurement control
  • Control Panel with 10 in touch screen
  • Overview of all important machine parameters
  • Programming of workforce and working wheels speed with ramps for each of the 5 working steps
  • Graphic display for stock removal  and working pressure
