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.
When we hear the term "High Speed Machining" (HSM), most people associate it with mold making, but what people fail to realize is that this technology is being used effectively by shops of every kind to positively impact the bottom line...and isn't that what everyone wants???
In today’s industry it’s all about quick setup and changeover between parts...especially in an environment where you run a high-mix of low volumes. In this article I want to discuss how part and tool probing can offer a real advantage for the shops that find themselves in this type of environment.
For the past ten years or so, we have seen 3D printing technology – also called Additive Manufacturing – really gain momentum in the industry. In fact, it has become so common-place that there has been speculation by some that it might actually replace traditional manufacturing in the not so distant future. Although I can see many benefits of this amazing new technology, and although I do agree that it will someday impact our lives – such as how we, as consumers, acquire many common household items - I have my reservations about how much it will ultimately change the need for traditional manufacturing processes as we know them. Because of the limitations on mixing printing materials, and the fact that the materials available for use in printing are not always the best for a particular application - not everything that can be printed, should be printed.
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.
Regardless of a particular OEM machine builder, there are several common machine configurations for 5-axis that are available - and each one has its own set of strengths that make it stand out among the choices. The most common types are: Table-Table, Head-Table, and Head-Head configurations.
When programming in 5-axis, we have two distinct options that we can use to command rotary moves and positions. We can output the data using either rotary angles, or tool vectors. Although each one has its pros and cons, I would prefer to configure a postprocessor to output these rotary commands as IJK tool vectors, instead of the more common ABC axis rotary angles, if given a choice.
Have you ever had to abruptly stop your machine, in the middle of running a program, and wished there was a way to recover exactly where you left off - even if you were in the middle of all that code? For years Hurco’s Recovery Restart feature offered operators a way to just that…but you had to know exactly what block you ended on to recover. Well not anymore! The WinMax version 9 software – which was released at IMTS last year – offers a new feature that will automatically insert a restart marker at the exact location of the last block executed before the interruption - which relives the pressure on the operator to remember (or guess) what block to restart program.
