STÄHLI: Feeling for Finishing
September 9, 2026 / 4:24 PM
Stähli Lapping Technology is a family company and Swiss machine manufacturer specializing in lapping and honing technology with about 50 employees. The headquarter is in Pieterlen where we develop and build the Stähli Machines. Our core competencies include mechanical engineering, customised processing and trading consumable materials developed by our company. Both, flat and round workpieces can be honed, lapped and polished with Stähli machines. We machine all types of materials, including steel, aluminum,
brass, ceramics, carbide, plastic, and many more.
In addition to the headquarters in Pieterlen, the Stähli-Group also has branches in Germany, the US, China and Eastern Switzerland. The Stähli-Group employs more than 100 people internationally for its customers. Various external distributors enable us to be close to our customers in all relevant markets worldwide. See our list of references on our website.
Our machinery portfolio includes:
- 1-WHEEL FLAT HONING AND FINE GRINDING
In the production of small and big series is a flexible production with high stock removal and highest precision required. This machine series is designed for these requirements and convinces with the In-Process measuring, automatic dressing and re-sharpening station and flexibility. Our portfolio includes a manual and a fully automatic version - 2-WHEELS FLAT HONING AND FINE GRINDING
The impressive DLM series, developed using the competence of the Stähli Group, is capable of flat honing with diamond / CBN wheels or alternatively precision grinding with conventional SiC or CORUNDUM working wheels.
Large production quantities with high stock removal demand high performance, precision, and productivity. The DLM machine series meets this requirement and is focused on user-friendliness and safety.
- 3-WHEELS FLAT HONING AND FINE GRINDING
The FH3 machine series has been developed for operation with automation. These machines have two lower grinding wheels, which can be swiveled 180°. Because of this, the processing down time is very short.
While one set of work pieces are being honed, a second set of honed parts on the second lower wheel are unloaded and unfinished work pieces loaded.
The FH3 series are also available in combination with automations. - 1-SIDE LAPPING AND POLISHING MACHINES
Our FLM machines are perfect for lapping and polishing with loose abrasive or flat honing with fixed abrasive wheels, and we know the right process for your application.
If you are focused on cost, flexibility, and reliability with the highest possible precision in your production, our FLM lapping machines are right for you. Whether you are grinding gear wheels with Ø 1 mm or housing plates with Ø 1000 mm, we have the right machine for you.
Versatile, efficient and precise: the my Läpp series delivers exceptional surface quality and outstanding accuracy, making it ideal for both single-part and series production. For more information, please refer to Mr. Beat Garo, who will be present at this year’s MSV in Brno.
We also manufacture customized machine sizes for you. Tell us your wishes and we will find a solution together. Benefit from our knowledge and decades of experience.
Flat-Honing
Flat-honing - also called fine-grinding - is a machining process with bonded grain. The work pieces are inserted in carrier wheels which form planetary kinematics with the inner and outer pin ring. The work piece is machined on the top and bottom or optionally also on one side. Large quantities of material can be removed in one work operation, but also the most precise roughness and flatness can be achieved.
Lapping
Lapping is defined as machining using a grain distributed loosely in a paste or liquid - lapping mixture. This is applied to a lapping tool - most often one that provides shaping - where the cutting tracks of the individual grains are largely non-directional. All types and sizes of work pieces in all possible materials and practically any required quality level can be machined.
Polishing
Polishing is a micro-finishing process which is used depending on the required surface quality. Thereby, both optical, shiny surfaces, as well as technical aspects play a role. The polishing process is used in combination with other processes such as polishing lapping or also polishing honing.
Do you have any questions about the "flat-honing, lapping or polishing" process?
We look forward to welcoming you at MSV 2026 in Brno, Hall P / Booth 001.
