The non rotating bar turning transfer machines are used for complete processing of complex parts which would normally require several processing stages. High productivity, comparable with several multi-mandrel lathes in parallel, tooling speed and processing flexibility and completeness, even on wide ranges of diameters, make them suitable both for limited lots and for larger productions. Bar automatic interlocking, up to a leght of 6 m and cut effort monitoring ensure unmanned processing for several hours. Usually they are configurated for simgle or double bar, with bar advancement/shearing station, processing in several stations of a side of the part and traslation of the part with additional processing on vice or self-centring spindle and turning column in the next stations, to process the opposite side of the part.

Owing to the acquisition around mid July 2007 of the company Namco SA in Caslano (Switzerland), Mikron Machining Technology widens its transfer systems portfolio.
Namco products are divided in two types of systems:
NAD extremely flexible and NAM extremely productive (up to 120 parts/min).
The main features of Namco products are:
• Preprocessing directly on the wire or on the bar before cutting, including
turning
• Complete processing of the work piece, such as drilling, threading,
milling, turning or broaching
• The extraordinary performance accuracy, typical of Mikron products
• The full CNC technology with the MTX control of Bosch Rexroth
• The high flexibility owing to the rapid clamping replacement, and the
possibility to produce various parts from one single wire and to unload
the finished parts in an automatic sorting basket
• The high productivity with a maximum of 18 CNC machining units working
at the same time and the double-wire feeding
• The use of an electronical probe for extremely accurate pieces allows to
measure the position of the premachined part and the following
automatic correction of the working unit.
With the Namco transfer systems, Mikron completes its application range with productive solutions in the field of locks, gas, watches, glasses, medical devices and the automotive industry.

Wherever high precision and increased production capabilities are important, the rotary transfer machining system Multifactor meets the requirements by producing economically, work pieces of medium size. This machine, of modular design, is available with 8, 10, 12 or 15 stations. The standard version has mechanically controlled stations, which do not require frequent change over. For increased flexibility, CNC controlled stations and/or CNC indexing work piece fixtures are available.

- 1st and 2nd operations on same lathe W22-T4;
- complete drilling on vertical drilling center DWN-22V.
The cycle can be carried-out only when the lathe Is equipped with pallet loading system. Production capability is influenced by the lathe's ability to machine 1st and 2nd turning operations in sequence of one another on a continuous basis.
As indicated in the machining cycle below, the theoretical production capability for the machining of a 15"x7" wheel is about 33 pcs./hour.

The patented Extrude Hone®/SurfTran® Thermal Energy Method (TEM) uses intense heat for deburring and/or deflashing. Parts to be processed are sealed in a pressurized cylindrical bell chamber with a mixture of a combustible gas and oxygen. This mixture completely envelopes the workpart's burrs and flash, regardless of their internal or external location. The gas mixture, ignited by a spark plug, creates an intense, rapid burst of heat. Burrs and flash, because of their high ratio of surface area to mass, quickly raise to a temperature well above their auto-ignition point and burst into flames.

Thermal Energy Method (TEM)
The patented Extrude Hone®/SurfTran® Thermal Energy Method (TEM) uses intense heat for deburring and/or deflashing. Parts to be processed are sealed in a pressurized cylindrical bell chamber with a mixture of a combustible gas and oxygen. This mixture completely envelopes the workpart's burrs and flash, regardless of their internal or external location. The gas mixture, ignited by a spark plug, creates an intense, rapid burst of heat. Burrs and flash, because of their high ratio of surface area to mass, quickly raise to a temperature well above their auto-ignition point and burst into flames.
Excess oxygen in the chamber combines with the vaporizing burrs to produce an oxide powder. As the oxidizing burr reaches the main body of the workpart, the temperature drops rapidly and stops the process. The oxidation is of very short duration; long enough to transform burrs and flash into oxide powder but not long enough to change workpart dimensions or metallurgy. Oxidized powder from the burrs is redistributed over the workpart and containment chamber which can be cleaned away, if necessary, with virtually any Aqueous (water-based) cleaning solution.
In summary, TEM is a rapid, low cost, high production process that has the unique ability to remove burrs and flashing without affecting adjoining workpart surfaces. Depending on workpart size, a million or more parts can be processed a month in a single TEM machine.

Vector Series abrasive flow machines have been redesigned through a joint effort between Extrude Hone Corporation and its customers. Over three hundred existing machine customers were contacted to provide input concerning a new machine design. The customers were asked for suggestions concerning machine operation, ease of maintenance, ergonomics and safety. The result is an extremely flexible Vector Series that is capable of polishing large extrusion and forming dies, multiple workpieces at one time and production deburring. The working tabletop has been lowered and enlarged, to accommodate bulky and heavy components. The abrasive media cylinders can be provided in sizes ranging from 4 inch diameter to 12 inch diameter. The Vector and the Vector HP offer a choice of pressure ranges to meet specific production requirements. Another standard feature on the Vector Series is the touch screen operator interface terminal which simplifies all machine functions in both an automatic or manual mode. This machine can also be ordered with optional flow control.

At the Heart of Extrude Hone
Extrude Hone patented the Abrasive Flow Machining (AFM) process in the 1960's as a method to deburr, polish and radius difficult-to-reach surfaces.
The typical AFM process (two-way flow) uses two vertically opposed cylinders which extrude an abrasive media back and forth through passages formed by the workpiece and tooling. Abrasive action occurs wherever the media enters and passes through the most restrictive passages. The extrusion pressure is controlled between 7-200 bar (100-3,000 psi), as well as the displacement per stroke and the number of reciprocating cycles.
One-way AFM systems flow the abrasive media through the workpiece in only one direction, allowing the media to exit freely from the part for fast processing, easy cleaning and simple quick-exchange tooling.
