Why Live Tooling for CNC? with Heimatec’s Preben Hansen

A brief introduction to the basics of this machine tool method, its concepts and recent developments in the technology

By Preben Hansen, President, Heimatec Inc., Prospect Heights, IL

Live tooling, as the name implies, is specifically driven by the CNC control and the turret of various spindle and powered sub-spindle configurations on CNC lathes to perform various operations while the workpiece remains in orientation to the main spindle.   These devices, whether BMT or VDI, are also called driven tools, as opposed to the static tools used during turning operations and are usually customized for the particular machine tool builder’s turret assembly.

+135º/-30 universal style adjustable tool might be the ideal solution for families of parts

Most often, live tooling is offered in standard straight and 90º configurations with a wide variety of tool output clamping systems, including collet chuck, arbor, Weldon, capto, whistle notch, hydraulic, HSK, CAT, ABS and a variety of custom or proprietary systems developed by the many suppliers to the industry.

As your jobs change or volume increases or you encounter specific challenges in machining very large parts with deep pockets or very small intricate parts, for example, and the need arises for new machinery, a common error is made by accepting the standard tooling packages provided by the builder.  This is most definitely not a criticism of the standard packages from builders, but this article is meant to give you a set of parameters to consider when evaluating the tooling and toolholding devices to use in your shop or production department.   Simply stated, you need to do as much evaluation of your process, when determining the proper tooling to be used, as you did when you evaluated the various machines available for purchase.

This examination can range from the simple (external vs. internal coolant, for example) to the sublime (adjustable or extended tooling configurations) to the truly exotic, an example of which will end this article.

Tool life is the product of cutting intensity, materials processed, machine stability and, of course, piece parts produced. Two seemingly identical job shops can have vastly different tooling needs because one is automotive and one is medical, or one specializes in the one-offs and low-volume work, while the other has a greater occurrence of longer run jobs. The totality of your operation determines the best tooling for the machines being purchased.

Example of a very large, deep pocket tool that initially seemed too expensive, until the tests proved otherwise

Bearing construction and the resulting spindle concentricity drive the life of any tool and you might find that just a 10-15% greater investment in a better design can yield both longer lasting cutters and consistently superior finish on your products. Of course, the stability and rigidity of the machine tool base are also critical factors, especially on large or deep pocket workpieces, where the distance from the tool base to the cutter tip is greater. Bevel and spur gears that are hardened, ground and lapped in sets are best for smooth transition and minimal runout. Roller bearings are consistently superior to spindle bearings in live tooling applications, so look for a combination system to get the highest precision possible. Also look for an internal vs. external collet nut, so the tool seats more deeply in the tool, as superior rigidity will result.

Internal clamping nut seats the tool more deeply

Likewise, coolant high pressure might be desirable. Look for 2000 psi in 90º and 1000 psi minimum in straight tools.

You need to ask another question, namely, is the turret RPM sufficient to handle the work to be done? It’s possible a speed increaser on the tool would be helpful. Would it be beneficial to move secondary operations to your lathe? Gear hobbing can be accomplished or producing squares or flats through the use of polygon machining.

Standard live tooling most often is best suited to production work, where the finish, tolerances and cutter life are critical, while quick-change systems may be better suited to the shop producing families of products and other instances where the tool presetting offline is a key factor in keeping the shop at maximum productivity.

This opens the discussion of long-term flexibility and it’s the most often overlooked consideration in buying live tooling. What work do you have in the shop, what work will be coming in the future and the overall economies of a changeable adapter system on your tooling may be considerations not often made when the focus is centered on the machine being purchased. Dedicated tools for large families of product may be desirable, but consider a changeable adapter system and talk to your supplier before making that determination. Likewise, if the future work you’re bidding involves more families of product, think ahead when buying the initial tooling on the machine.

If standard ER tooling is suitable for the work, there are many good suppliers but do consider the construction aspects noted above. For a quick-change or changeable adapter system, there are fewer suppliers in the market, so seek them out and be sure they can supply the product styles you need for all your lathe brands. Adjustable angle head systems can be costly but very worthwhile, owing to the stability and rigidity of their construction, when producing families of parts with only slight differences in the dimensions.

Now, one of the exotic examples promised earlier…it evidences the value of having test runs done on alternative tool styles…

Internal clamping nut seats the tool more deeply

One company was doing a cross-milling application on an AL6063 sheave, using an ER40 output tool on a Eurotech lathe, running 10 ipm at 4000 rpm. They were making three passes, with a cycle time of 262 seconds and getting a chatter finish on 20,000 pieces per year. The annual cost of the machining was over $130,000. By using an improved adapter tool design with ER32AX output and the same parameters, they were able to produce the part in a single pass with a smooth finish and cycle time of just 172 seconds. Over the course of the year, this turned into a savings of $45,000, approximately 20x the cost of the tool. The bottom line is the bottom line, as the accountants tell us.

In the end, you may not need a +135º/-30 universal adjustable tool or a multi-spindle live holder or even a quick-change adapter system, but do consider all the options. Talk to your machine builder and several tool suppliers, plus the most important people in this equation, your shop personnel, as their input is invaluable.

HT Series… Fastest Quick-Change Tool Adapter System On The Market!

New Heimatec system reduces downtime, eliminates costly changeover; ideal for the busy job shop or production department

HT Series quick-change tool adapter system from Heimatec requires only a single clamping bolt turn for changeover. Click the image to view the animation.

Heimatec, a world leader in live tools, angle heads and multi-spindle drill heads, announces immediate availability of its newest development, the HT Series quick-change tool adapter system.  With the HT Series onboard, users do not need to change tooling, only the adapter and that action is accomplished with a single clamping bolt.  In this way, collet assemblies can be preset outside the machine tool, then simply swapped out as needed.

Whether a one-off job shop or long run production department, downtime on any machine tool is costly and the HT Series reduces changeover from an average of 15-20 minutes down to about that many seconds.  The tool head stays in the machine, so less probing is needed after the changeover, as well.

HT Series offers users a lower initial investment, minimized tooling time, reductions of tooling quantities and related costs, plus considerably lower inventories.  Further savings are realized by the high degree of flexibility in the system, the shortest gauge line of any system on the market, meaning no additional tool length consumed, standard coolant-through design, exceptional repeatability to 0.0002” and easier handling of the components, resulting in lower setup costs.

This new quick-change system is available from Heimatec with all common outputs, including collet, extended collet, collet with tension and expansion for tapping, weld-on, weld-on extended, arbor, hydro-chuck, indexable insert holder, shrink fit and blank/plug design.
