If you want to clamp your workpieces efficiently for milling, LANG Technik is the right choice: We offer you an extensive range of innovative workholding and perfectly matched zero point clamping systems. The powerful combination of both technologies can be used universally in all milling machines. Our unique automation system makes this combination even better and makes optimum use of the strengths of our own workholding - you cannot design your production processes more economically. These three pillars - workholding, zero point clamping and machine tool automation - form the stable foundation for your modern production. Proven over many years, high quality and with an excellent price-performance ratio.

The hardness of the cutting tool material will also have a great deal to do with the recommended cutting speed. The harder the drill, the faster the cutting speed.  The softer the drill, the slower the recommended cutting speed (See Figure 2).

Large workpieces and sheet material require large solutions: Thanks to its modular design, the Makro•Grip® Ultra presents itself as a workholding technology solution that leaves nothing to be desired thanks to the wide range of clamping jaw options. Benefit from the fast set-up of the system and make optimal use of quick jaw adjustment and expansion options for your applications up to clamping ranges of 810 mm.

Drilling machines that have power feeds are designed to advance the drill a given amount for each revolution of the spindle.  If we set the machine to feed at .006” the machine will feed .006” for every revolution of the spindle. This is expressed as (IPR) inches per revolution

When things get tough, you can be sure of making the right choice with our contour clamping vises. Here, workpiece clamping of difficult shapes becomes an easy task thanks to top jaws/ contour jaws. Look forward to fast and flexible change-overs with these clamping systems. Plus, you can also rely on maximum holding forces when clamping cylindrical parts: Thanks to several collet chucks for ER 32 and ER 50 collets and a versatile 6-jaw chuck (with exchangeable top jaws), you can confidently handle such processes as well.

On the milling machines we have here at LBCC, the feed is independent of the spindle speed.  This is a good arrangement and it permits faster feeds for larger, slowly rotating cutters.

A good workholding system must be able to accomplish one thing in particular: To securely clamp workpieces regardless of their size with the least amount of space required. Our clamping systems do just that. It is the flexibility and user-friendliness that give you added value in your production. And that's regardless of whether you use 5-axis vises, centering vises, collet and jaw chucks or 5-axis vises with top jaws. We at LANG Technik have the right workholding system in every case. You can count on our clamping devices to securely fix any of your workpieces in a time-saving manner.

Feed per tooth, is the amount of material that should be removed by each tooth of the cutter as it revolves and advances into the work.

HAUBEX enables the automatic exchange of the workholding device from the tool magazine with a hood as a carrier system for the vise and workpiece blank.

This chip thickness or feed per tooth, along with the number of teeth in the cutter, form the basis for determining the rate of feed.

When drilling and tapping, it is crucial to use oil.  It keeps the bits from squealing, makes the cut smoother, cleans out the chips, and keeps the drill and stock from overheating.

The feed (milling machine feed) can be defined as the distance in inches per minute that the work moves into the cutter.

The modular workholding system is characterized by an enormous application variety and is ideally suited for clamping plates and large parts.

Pecking helps ensure that bits don’t overheat and break when using them to drill or tap.  Peck drilling involves drilling partway through a part, then retracting it to remove chips, simultaneously allowing the piece to cool.  Rotating the handle a full turn then back a half turn is common practice.  Whenever the bit or tap is backed out, remove as many chips as possible and add oil to the surface between the drill or tap and the workpiece.

Anyone who is buying into our 5-Axis Vises today is also buying into compact workholding technology and thus to optimum accessibility in 5-sided machining. Our 5-axis vises can achieve enormous holding forces like hardly any other clamping system. In combination with the stamping technology, they hold the workpiece by form-fit on just 3 mm. Best of all, these centering vise also hold workpieces that are much larger than the 5-axis vise. Secure clamping has never been easier – Makro•Grip®.

Tap guides are an integral part in making a usable and straight thread.  When using the lathe or the mill, the tap is already straight and centered.  When manually aligning a tap, be careful, as a 90° tap guide is much more accurate than the human eye.

You know it yourself: Designing solid workholding is anything but easy. To ensure that your workpieces - from the blank to the finished product - are secure throughout the entire process, we at LANG have put our vast know-how into workholding that leaves nothing to be desired. Convince yourself of clamping systems that are more than of handling the daily demands of cnc machining. Proven over years, high quality and reasonably priced.

Cutting speed is defined as the speed at the outside edge of the tool as it is cutting.  This is also known as surface speed.  Surface speed, surface footage, and surface area are all directly related.  If two tools of different sizes are turning at the same revolutions per minute (RPM), the larger tool has a greater surface speed.  Surface speed is measured in surface feet per minute (SFM).  All cutting tools work on the surface footage principle.  Cutting speeds depend primarily on the kind of material you are cutting and the kind of cutting tool you are using.  The hardness of the work material has a great deal to do with the recommended cutting speed.  The harder the work material, the slower the cutting speed.  The softer the work material, the faster the recommended cutting speed (See Figure 1).

Feeds for end mills used in vertical milling machines range from .001 to .002 in. feed per tooth for very small diameter cutters on steel work material to .010 in. feed per tooth for large cutters in aluminum workpieces.  Since the cutting speed for mild steel is 90, the RPM for a 3/8” high-speed, two flute end mill is

Maximum efficiency with minimum use of resources - the revolutionary quick-clamping system for all machine tables and automation pallets in the CNC milling sector.

Once the SFM for a given material and tool is determined, the spindle can be calculated since this value is dependent on cutting speed and tool diameter.

The chip fan automatically removes chips and coolant from machine tables, fixtures and workpieces after the machining process.

As the work advances into the cutter, each tooth of the cutter advances into the work an equal amount producing chips of equal thickness.
