While there are some similarities among different types of tools, there are many differences as well. Machining tools, unlike hand tools, are made up of several different parts, such as tool holders and tool presetters. It is necessary to assemble the parts correctly, and accurately, in order to ensure that production is error free.
As of 2010, there were approximately 939,700 people employed by the machining industry.
In machining, tool holders are not for the storage of tools, but are used to securely hold tools in CNC machining devices for accuracy. Tool holders are often utilized in high speed, high velocity machining.
Tool presetters are used before the machining tools are used. The use of tool presetters ensures that the tools are in precisely set in order for a CNC machine to work accurately and efficiently, without down time. Machining tools perform two different functions. One is to constrain the work piece, and the second is to provide guidance in movement of the machine parts.
