Machines

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

Size Control & Driven Head

Increased quantities and series production with rapid stock removal require more performance. Our FH 602 machine is dedicated to high productivity, user-friendliness, economic efficiency, precision and safety. Flat Honing with diamond or CBN-wheels opt for a future in superfinishing with a newly developed machine from the STAHLI Group.

Our single-side Flat Honing Machine with process control and size measuring system as well as loading and unloading tables meet thus requirements.

• High precision in-process size measuring system
• Process controlled machining
• High availability
• Loading table and unloading table for easy workflow
• Touch screen user interface
• Process adapted drives/speeds/pressures
• Energy-efficient
• Short changeover time
• Remote maintenance/online support
• Guarded work enclosure and splash shield

Lapping or polishing with free-rolling particles or flat honing with fixed or super abrasive wheels – the machines of our FLM 1800 – 3250 range are real all-rounders. Their employment in both large and small manufacturing shops is multipurpose and includes single piece machining as well as performance-oriented series production. Their technological advantages are well in evidence:

• Quick adjustment of the lapping wheel
• By means of the central screw
• Minimum loading, turning, and unloading times with user-friendly special facilities
• Optimal maintaining of a flat working wheel
• Wheel cooling
• Quick and easy wheel change
• Stable bearing arrangement for quiet operation
• Modern single-arm pneumatic construction for optimal accessibility and reduction of working times
• Various dosage systems of lapping and polishing materials for economic consumption
• Integrated inching system
• Robust construction

More Information On Our FLM Series Machine

Our FH2-505 machine is dedicated to high productivity, user-friendliness, economic efficiency, precision, and safety. Flat Honing with diamond or CBN wheels opt for a future in superfinishing with a newly developed machine from the STAHLI Group. In addition, this machine can be adapted and used as a 2-sided lapping machine with cast iron plates in combination with lapping liquid. Our double-sided Flat Honing machine is solid, compact, and ergonomic. Its construction combined with in-process measuring guarantees an efficient high precision machining, with high stock removal and fine surface quality.
