A toolholder is the mechanical device, like a lathe chuck, that holds the cutting inserts in machines such as drills and mill machines. When buying a toolholding kit for a machine, it is important to make sure that the kit is an ideal fit. Before buying a toolholding kit, there are a few things to keep in mind: toolholding rigidity, machine spindle style and size, and the material being cut. Buying toolholding kits that provide the maximum rigidity will help improve the life of your tools and ensure that your machine operates effectively. As the spindle speeds increase, and machines are needed to operate at a variety of different speeds, the rigidity of the tools become very important. The overall balance of the machine and the tools is essential during high-speed use, and the correct tools will help overcome this problem. Although most machines operate with a V-flange style spindle, there are other styles that are becoming popular. Many high-speed machines, for example, are using smaller spindles such as the BT style spindle, while the HSK shank is being used more often in high-production machines. It is important to confirm the correct spindle type and size first, so you can be sure that you are making the correct purchase. If you work with the same materials regularly, you should chose a toolholding kit that works well with the materials being machined. To keep your machines running at top efficiency, the proper cutting tool, holder and insert should be used. If you work with high-speed machines, you should also try to use toolholders that will stay balanced during use. The industry has been improving its efforts to create balanced toolholders, and many models are now available that can handle the high-speeds of today's machines. |
