One of the features about a Hurco that many customers love is the 8-nozzle coolant ring that comes standard on all VMX models of vertical machining centers, and the amount and flow of the flood coolant that can be experienced is sometimes unbelievable to many new users. Now Hurco VM owners can experience this same overwhelming feeling of flood coolant!

Over the years, Hurco has partnered with many tooling companies. Recently I received a link from G.W. Shultz, that showed a video of one of thier tools cutting 422 Stainless Steel, on a Hurco VMX30HSi High Speed milling machine - at some pretty impressive speeds. The information listed in the video comment section says: "Pushing the G.W. Schultz Tool HGW40250-01 to 1000SFM in 422 Stainless Steel".
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.
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.
As many of you are already aware, the Absolute Tool Length method of tool calibration has become the industry standard for measuring and recording the length of individual cutting tools on milling machines. This method of tool measurement not only produces numerical values that make sense to the operator, and can easily be verified with a pocket scale, but will also allow for tool lengths to be set offline using a presetter - and then the data can simply be entered into the tool setup for that particular tool…helping to reduce setup time at the machine.
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.
