When purchasing a CNC lathe, there are several questions that you need to ask yourself before you begin the process. Some of these questions will be quite obvious: How much axis travel do I need? What size chuck should I look for? How many tool stations are on the turret? What is the spindle bore size? Etc... However, there are other specifications that are just as important, but not always so obvious: What is the maximum swing distance that my work will require? What is the maximum turning diameter necessary for my family of parts? What kind of spindle horsepower and torque will my type of work consume? The first set of questions above is relatively easy to answer, but the second group requires a better understanding of lathes in general.

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.
A few months ago I published a two-part series on the basics of mill-turn technology, where I covered topics such as: axis configurations, the orientation of live tooling holders, mill-turn terminology, instances when a Y-axis might be necessary, etc… In today’s article I want to discuss the differences between the driven tool mounting configurations, and offer my opinions on the benefits and challenges associated with each one.
As machinists we are all aware of the standard tools of our trade; however, there are other non-standard tools available - that not everyone is aware of - that could be very helpful in our day-to-day life in the shop. Just like any other industry, if there is a time consuming and mundane procedure that must be completed, you can bet that somewhere there is someone who has already invented a tool or device that would make that task easier…if we only knew where to go to find those tools.
For anyone new to 5-axis machining, it should quickly become apparent that fixturing can be one of the single most challenging tasks that you will face during the setup process. Although there are many different styles of professionally manufactured workholding devices available, from a variety of different manufacturers - like Kurt, Raptor Workholding, Lang, Jergens, Bock, Hirschmann, and System 3R just to name a few - creativity is the name of the game.
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.
