Carbon Fibre Scissors

Transcription

1 Carbon Fibre Scissors A range of shears specifically designed to work with modern technical fibres used in an ever increasing range of product from ballistic protection, aerospace, automotive through to wind turbines, roofing etc Developed with innovators in industry to ensure maximum performance 1. What makes good scissors? A quality scissor will generally be made of "Hot Forged" high carbon steel, hardened and tempered. The process of forging the steel in a drop hammer strengthens the crystal structure of the steel, the hardening is a scientifically controlled process further enhanced by tempering which provides an optimum uniform hardness on the blades prior to grinding. Great care is taken to finish all the surfaces, particularly inside the bows to achieve maximum comfort of use. 2. Choosing the best scissors for the job Using the right scissor ensures that the job will be easier, safer and more effective. The following points will help you choose the most suitable scissor: Choose the size appropriate to the type of job. Big scissors are used for cutting large amounts of material, scissors with short blades and long shanks for cutting through thick material and small sharp scissors for work which requires a high degree of accuracy. Using the wrong size deforms the pivot and reduces the performance and life expectancy of the scissor. Select the biggest pair of scissors that can be comfortably held. Some materials such as Carbon Fibre, Glass Fibre and Aramid (Kevlar) are very difficult to cut using normal scissors. The development of a special range allows these modern materials to be cut successfully through special machining, setting and a Teflon coating. These scissors have a ten-fold cutting life extension when compared to standard scissors. It is not recommended that these scissors be used to cut both glass fibre, Carbon fibre or Kevlar because users have reported a rapid fall-off in performance. If cutting both types of fibre, use one scissor exclusively on each of the three types of fibres.

6 4. Maintenance Following these guidelines for maintenance and care for maximum cutting-life and satisfaction : Always use the correct pattern for the job Using an incorrect size or pattern could lead to damage to the scissors, distorting blades and damaging edges rendering the scissors unserviceable. It will almost certainly increase the effort required by the operator to complete the task which also has a bearing on productivity. Wipe the blades of the scissors after use with a soft oily cloth. This extends the life by removing tiny particles of dust and fibre which build up between the blades and also acts as a protection against corrosion on carbon steel patterns. This build-up can also impair the cutting ability. Avoid harsh treatment of the scissors. Dropping them can cause irreversible edge damage if the blades are open. Leather holsters are available which protect both scissor and operator. Keep away from moisture. Steam, humidity and perspiration can cause damage through corrosion. Lifetime and Re-sharpenning : The lifetime of the scissors will depend on the intensity of the work and their maintenance. However, these scissors are made for cutting very aggressive materials; their lifespan may be limited in time if their use is daily and intensive. We do not recommend re-sharpening of the blades; from experience it is has not proved to be cost effective and the quality of the re-sharpened blades are not comparable to a new pair of scissors.
