New high energy mass finishing solution for garden shear components

Optimised finishing process at Gardena increases productivity and lowers costs

Improved productivity , increased production capacity , better quality and lower costs . These were the demands of a leading garden tool manufacturer , when the company invested in a new mass finishing system for deburring and polishing of garden shear knives . Rösler met this challenge with a tailormade Keramo-Finish process that is run in a double batch centrifugal disk finishing machine FKS 35.1 A2-So with fully automatic work piece handling . In a two-stage process the stamped and laser-cut knives are deburred and polished in the FKS finishing machine . Subsequently they are dried in an energy-efficient rotary dryer and prepared for the next manufacturing step .
For more than 60 years , Gardena , a brand of the Husqvarna Group , has been offering everything ardent gardeners need . The broad product range includes innovative systems for irrigation , lawn , tree and shrub care , as well as soil cultivation . Gardena products are used in more than 80 countries all around the world .
A transformation to ultra-modern equipment and process technologies
To ensure easy and simple handling , produce excellent cutting performance and guarantee a long service life , the shear components are produced with state-of-the-art manufacturing technologies . Important steps are the stamping or laser cutting of the upper and lower knifes followed by a deburring and polishing process in mass finishing equipment . Previously the lower knifes required two separate finishing operations , one in a rotary vibrator and one in a centrifugal disk finishing machine .
To combine these two operations into one and adapt them to the latest manufacturing requirements , the existing mass finishing equipment , used over many years , was replaced . Gardena chose a finishing solution from the Rösler Oberflächentechnik GmbH , who had already supplied the machinery used to date . By investing in new equipment the customer was looking for a comprehensive optimisation of the finishing process that improved not only the productivity and offered a higher capacity but also resulted in lower costs .
