The New Dual table CNC by Milltronics

November 19, 2008

“Keep your CNC operator busy every moment”. Based in this concept Milltronics Manufacturing Company has increased up production on its newly designed Dual or Twin Table TT Series machining centers to meet the increasing customer demands.
This unique CNC machine design offers two separate work tables that shuttle outside the working area for convenient part loading while the opposite work table is inside the machining enclosure cutting parts. Finished the machining operation, the individual work tables shuttle the completed parts out and the next table enters the work area for machining, creating a non-stop machining cycle.
The rigid cast iron bridge design of the TT24 and TT40 CNC machines utilizes a single set of linear ball or roller ways with independent ball screws and axes motors for table control providing superior accuracy and cutting performance. Enhancement of the TT’s cutting performance is provided through an Inline spindle, available standard at 10,000 RPM or optional 15,000 RPM. With 1600 IPM rapid traverse rates on the TT24 and TT40, high RPMs, high speed double arm ATC on the TT24 and TT40, plus the elimination of spindle down time for part loading typical of conventional machining centers, the TT CNC Series raises a new meaning to Lean Manufacturing.
These machines are available in three sizes, the TT24 with a 24″ square work envelope, the TT40 with a 40″ square work envelope, and the TT60 with twin 60×80″ tables, the TT Series machines deliver a new level of cost effective machining to small and large shops alike.
These are some TT24’s characteristics or features according to Milltronics:
-Fully integrated twin pallet machine with a unique design requiring no pallet removal
-Conversational programming with Milltronics CNC control
-Inline spindle design – 24 HP standard with 35 HP option
-Reduced cycle times due to no part loading time
-100% cast iron design with 10,000 lb machine weight
-1600 ipm rapids
-24 pocket tool changer standard
-Large memories for part storage and execution
-Ground ball screw construction
True encoder positioning feedback
-Graphic program verification
-No leaning into the machine!
-No doors to open and close!
-No time lost changing parts!
-Accurate time management
-Superior chip and coolant control
-Designed and built by American craftsmen.

For Aerospace Production, Integrex e-Ramtec V8

March 2, 2008

The INTEGREX e-RAMTEC V/8 is doted with a ram spindle, whose cutting heads are automatically changed by the ATC to do deep I.D. turning and I.D. angle head drilling.
This CNC machinig center was disigned for aircraft, ships, construction machinery and other large items to vertical lathe-based development of complex machining, in addition to the usual set up a dedicated spindle machining diameter of the shaft so that the diameter can not change tooling for processing.
The axis distance reach 900 MM and has a 40 collection tools, performing a long time task, along with the cars and milling function.

There is no need to change the tooling, which minimize the processing time for instance before you’d needed 1oo hours of processing now you only need 12 hours to complete a mechanical task and the precision has increades as well.
This smart machine can detect thermal deformation and prevent mechanical interference, can inspect the center of gravity position.

CNC lathes

CNC Lathe

CNC Lathe and turningCNC lathes are rapidly replacing the older production lathes (multispindle, etc) due to their ease of setting and operation. They are designed to use modern carbide tooling and fully utilize modern processes. The part may be designed by the Computer-aided manufacturing (CAM) process, the resulting file uploaded to the machine, and once set and trialled the machine will continue to turn out parts under the occasional supervision of an operator. The machine is controlled electronically via a computer menu style interface, the program may be modified and displayed at the machine, along with a simulated view of the process. The setter/operator needs a high level of skill to perform the process, however the knowledge base is broader compared to the older production machines where intimate knowledge of each machine was considered essential. These machines are often set and operated by the same person, where the operator will supervise a small number of machines (cell). The design of a CNC lathe has evolved yet again however the basic principles and parts are still recognisable, the turret holds the tools and indexes them as needed. The machines are totally enclosed, due in large part to Occupational health and safety (OH&S) issues. With the advent of cheap computers, free operating systems such as Linux, and open source CNC software, the entry price of CNC machines has plummeted. For example, Sherline makes a desktop CNC lathe that is affordable by hobbyists. Most CNC Swiss style lathes today utilize two spindles. The main spindle is used with the guide bushing for the main machining operations. The secondary spindle is located behind the part, aligned on the Z axis. In simple operation it picks up the part as it is cut off (or parted off) and ejects it into a bin, eliminating the need to have an operator manually change each part, as is often the case with standard CNC turning centers. This makes them very efficient, as these machines are capable of fast cycle times, producing simple parts in one operation in as little as 10-15 seconds. This makes them ideal for large production runs of small diameter parts.

CNC Machinig Centers

Machining Center

CNC Machining Center. The introduction of CNC machines radically changed the manufacturing industry. Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of machining steps that required human action have been dramatically reduced. With the increased automation of manufacturing processes with CNC machining center, considerable improvements in consistency and quality have been achieved. CNC automation reduced the frequency of errors and provided CNC operators with time to perform additional tasks. CNC automation also allows for more flexibility in the way parts are held in the manufacturing process and the time required to change the machine to produce different components. A more recent advancement in CNC interpreters is support of logical commands, known as parametric programming. Parametric programs incorporate both G-code and these logical constructs to create a programming language and syntax similar to BASIC. Various manufacturers refer to parametric programming in brand-specific ways. For instance, Haas (machining center) refers to parametric programs as macros. GE Fanuc refers to it as Custom Macro A & B. While Okuma refers to it as User Task 2. The programmer can make if/then/else statements, loops, subprogram calls, perform various arithmetic, and manipulate variables to create a large degree of freedom within one program. An entire product line of different sizes can be programmed using logic and simple math to create and scale an entire range of parts, or create a stock part that can be scaled to any size a customer demands. A horizontal machining center has the same sort of x–y table, but the cutters are mounted on a horizontal arbor across the table. A majority of CNC vertical machining also feature a degree rotary table that allows milling at shallow angles. While endmills and the other types of tools available to a vertical mill may be used in a horizontal mill, their real advantage lies in arbor-mounted cutters, called side and face mills, which have a cross section rather like a circular saw, but are generally wider and smaller in diameter.
