Introducing The Bridgeport GX 300 & GX 510 VMCs

November 9, 2009

Hardinge announces the newest members of the GX-Series of Vertical Machining Centers as a standard product offering in North America.  These machines are designed and built for a production environment.  The machine can literally overlap one another to better utilize valuable floor space and to promote cell manufacturing.  The unique design provides service and operator interface to only the front or back of the machines.  This design allows the machines to be stacked in a line side by side since there is no need to access the sides of the machines.  Don’t let the small footprint fool you as the GX 300 & 510 packs a powerful punch. 

A unique feature of this milling machine is the spindle torque and horsepower compared to other small footprint machines.  With 20 horsepower and 99 ft-lbs of torque the GX300 & 510 is able to provide a solution for the aerospace, medical, defense, 3C, automotive and other industries, requiring high-value, complex parts from difficult to machine materials.  

Some of the key differentiators of these machines are:  Heavy-duty linear roller guide-ways ensuring a stiff machine design.  High acceleration rates of the spindles and axes required for high production. Standard with swing arm ATC, required for high production. Also, this machine is designed to support single piece flow and/or automated parts handling.

Bridgeport Releases NEW 5-Axis VMC

October 28, 2009

Introducing the newest member of Bridgeport’s Five Axis VMCs – - the fully-integrated 5-axis XR 300 5AX High-Performance vertical machining center is built to suit all manufacturing requirements.  This machine is positioned in the top of Bridgeport’s machining center portfolio. Our 5-Axis VMCs are ideally suited for a diverse range of applications within the aerospace, automotive, motor sport, medical, mold and tool and die sectors.
The 255mm (10″) diameter integrated dual-axis rotary table with 150-degree tilt and 5-arc second accuracy enhances the machine’s flexibility and high precision machining capability. The ability to machine complex shapes, undercuts and difficult angles in a single setup reduces tooling cost and labor time, resulting in lower cost per part in addition to maintaining parts conformity throughout production runs. The machining center is equipped with a 48-tool carousel-type automatic tool changer (ATC) features random access, bidirectional indexing and 4.6-second chip-to-chip change time.

Calculating RPMs for Lathes and Mills

February 3, 2009

Determining the proper rpm for a rotating tool for milling or drilling, or the proper rpm for a chuck when turning on cnc lathes, is a question many new CNC programmers are often faced with. Before calculating the RPM of the tool or part, here are two basic things you need to know:

  1. Material (Aluminum, Brass, Steel, etc.)
  2. Cutting tool composition (HSS, Carbide, Ceramic, etc.)

All cutting tools have an ideal cutting speed based on the material. Brass or aluminum cuts easier than steel for example. Cutting tool manufacturers have this information available through catalogs, tech support phone numbers, or possibly websites. If no other information is available to you, the Machine Tools Handbook will have some basic guidelines in the chapter devoted to “Speeds and Feeds” – http://search.barnesandnoble.com/booksearch.

Let’s start with an example for milling applications. Say you have a high-speed cutter (HSS) and want to machine 6061T6 aluminum. You can look in the cutting tool manufacturer’s catalog and find that you can use 250 surface feet per minute when you have a ½” (.500”) diameter end mill.

Here’s a quick and easy way to calculate the answer. The formula is:

Multiply 12 times 250.  (Answer is 3000.)
Multiply the diameter of the tool times π (pi)   ( .5 * 3.1416 = 1.5708 )
Take 1.5708 and divide that into 3000.  Your answer should be 1909.85485
The proper RPM is:  1909

Tip!

If you do this a lot, enter this formula into a programmable calculator or an Excel spreadsheet as follows:

In cell A1 type the text “Enter Surface Speed”; in cell A2, type the text “Enter Tool or Part Diameter” and in Cell A4, type the text “Calculated RPM”.  In cell B1 type the number 250.  In Cell B2, type .500

Cell B4 is going to contain your answer. So type the formula in the cell like this:  =(12*b1)/(b2*3.1416) and press the ENTER key.

You can “right mouse click” on cell B4 and click on “Format Cells” and choose the “Number” tab and change the decimal places to “0” so your answer is in even numbers.

That’s it!  Save the worksheet and you can easily calculate proper RPM’s for yourself.
