As machinists we apply our skill, knowledge and experience to produce the best looking and most accurate parts that we can. We take a great deal of pride in the products that we produce, and we want others to see that pride in the finished product. But what do we do when we aren’t getting the results that we want? When dimensionally the parts meet blueprint specifications, but the surface finish and overall appearance is less than desirable? When this happens we need to go back the basics and ensure that we are using the best machining practices that we know to be correct.

There are several things to keep in mind when you are in the market for a new 5-axis machining center. To be successful, you must make sure that the machine will fit all of your needs, not just your current one. Often times the purchase of a 5-axis machine is driven by a particular job or part, and sometimes shops fail to consider the other work they could run on the machine. Remember, size does matter.
High speed machining is usually associated with any spindle speed above 15k rpm, but it is much more than just a faster spindle. The whole machine must be considered when selecting a good candidate machine for HSM. Thermal compensation, overall machine rigidity and construction, positional feedback, the motion control system, tool retention, and many other characteristics must be looked at, in detail, before determining that a particular machine is suitable for the task.
Hello, and welcome to the Hurco blog. I will be updating and posting something new each week on a variety of different subject matter: high-speed and 5-axis machining, workholding, the latest control technologies, and Hurco tips-and-tricks…just to name a few.
