FAQ - frequently asked questions
Does the ISF Process cause hydrogen embrittlement?
The ISF Process produces a slightly oxidizing environment in the vibratory equipment. Hydrogen is not generated. The ISF Process has been repeatedly tested and proven to be free from causing hydrogen embrittlement. The process is metallurgically safe.
Does the ISF Process have any detrimental effect on the geometry of the part?
No. The ISF Process has been certified for use on DIN 2 (AGMA Q 13) quality gears. Material refined from the surfaces of gear flanks is uniform in profile and from tooth to tooth. Depth of material removed by the ISF Process is typically 0.006 mm.
Are there safety or environmental concerns with the chemicals used in the ISF Process?
The chemicals are non-toxic and non-hazardous and have been used in industrial settings for over 20 years. However, the standard precautions when dealing with chemicals should always be observed.
Are there special waste water treatment considerations?
Very little waste water is produced by the ISF Process and in most cases this water can be treated in an effluent treatment plant similar to those used for conventional vibratory finishing systems. (In most cases existing plants can be modified to treat the waste produced by the ISF Process). However, regulations controlling effluent treatment plants vary from country to country. It is therefore advisable to contact your local authority to discuss the situation.
Does OSRO provide sub-contracting services?
Yes. In addition to sales of the equipment and chemicals, a large part of our business is providing sub-contracting facilities. (link to OSF)
Is there a size limitation of parts?
We have successfully processed components as small as the head of a match and weighing only a few grams, and as large as 1800 mm diameter and weighing 1800 kgs. Machines for processing components weighing up to 5000 kg are currently being developed.
How long has this process been in use?
REM Chemicals pioneered chemically accelerated vibratory finishing in 1983 and have continualy improved it since then. In 1989 the non-abrasive processing technique was introduced. The process has been tested and proven to be effective in both industrial and military applications.
How much training is necessary to learn how to use the process?
Once the equipment is installed OSRO will provide the necessary training to your personnel. No particular expertise is required to operate the equipment. Our technical staff is available deal with any questions, concerns or problems. We pride ourselves on the excellence of our customer service.
Is the ISF Process expensive?
No. Whether you choose purchase equipment from us or use the jobbing services or our sister company, Osro Superfinishing, the process is extremely cost effective. In fact, once the savings of reduced downtime and extended service life are taken into account, there won’t be any question as to the value of the ISF Process.
