GEHRING / Cylinder Block Thermal Spray Pre-Laser Rough Machining Machine
Optimal for rough surface processing of thermal spray bores, laser rough surface processing machine.
Rough surface processing (laser roughening) is equipment that performs rough surface processing inside engine bores using lasers. This is done to enhance the adhesion between the base material and the thermal spray material. By creating a special profile shape on the inner surface of the bore with a laser, it not only generates a higher adhesion compared to conventional mechanical roughening but also allows for a shallower depth of the roughening profile. This not only reduces the cycle time for thermal spraying but also significantly decreases the amount of thermal spray material used. 【Features】 ■ By configuring the equipment in a two-axis structure, simultaneous processing of #1 bore and #3 bore, as well as #2 bore and #4 bore, is possible.

We will be exhibiting at the 18th Automotive World - Advanced Automotive Technology Exhibition.
Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your company. I sincerely appreciate your exceptional support as always. We will be exhibiting at the Automotive World 2026. - Gehring's "Hairpin Stator Manufacturing Line" from Germany We will introduce a series of manufacturing technologies used in the production line for EV stator components. We will display samples of the finished hairpin stators, and in a collaborative video with WAFIOS, you will be able to see a series of manufacturing processes including pin production, assembly, pin expansion and bending, welding, impregnation, and powder coating. Additionally, we will also showcase samples of honing tools and laser roughening at the same booth. Gehring and WAFIOS have been in a cooperative relationship since April 2021, aiming to provide a turnkey solution for hairpin stator manufacturing lines. This exhibition will be presented as a joint exhibit by our company, the agent for Gehring, and CORRENS, the agent for WAFIOS.
