Mitsui Seiki Launches New Vertex 75X II Vertical Machining Center

Mitsui Seiki has evolved its popular “Vertex 750-5X” line of machines with new features and capabilities, and a broader range of options and configurations within the series. The new model series, comprising six distinct models, is now called Vertex 75X II. Linear axes (X, Y, Z) strokes are 750 mm (29.5”) x 800 mm (31.4”) x 700 mm (27.5”).

 

One of the key new features is an enhanced ultra high accuracy package. This option enhances Mitsui Seiki’s existing, well-established construction techniques for accuracy and precision. As such, the Vertex line of machines are very well suited for tight-tolerance mold and die work, aerospace, energy, and other high precision component applications. Users can gain significant production improvements eliminating the traditional machine ‘warm up’ time for very demanding precision jobs. Machine geometry is still unparalleled, and Positioning Accuracy in X, Y, and Z axes is 0.001 mm (0.000040”). A-axis: ±6 arc seconds; C-axis: ±4 arc seconds.”

 

In response to customer feedback and market demands, Mitsui Seiki now offers a new 30,000 rpm spindle with the Vertex 75X II, in addition to the 15,000,18,000 and 25,000 rpm choices. Customers can now take full advantage of the machine’s acceleration and deceleration characteristics and high speed machining functions. An HSK-80 taper spindle connection (for those requiring more heavy-duty machining) is available as an option to compliment the existing HSK-63 and 40-taper tool interfaces.

 

The Vertex 75X II line includes several configurations in the range, based on table sizes and types from 225 mm (9”) to 500 mm (19.7”) diameter. A choice of rotary axis drive systems – high torque geared type or direct drive – allows for the optimum machine configuration to suit the customer needs.

 

Mitsui Seiki’s tradition is to build rigid and ultra precise metal cutting and grinding machines. The Vertex 75X II geometric accuracy is carefully monitored in the tightest temperature-controlled factory environment in the world.  The machine features a proprietary cast iron bed, which provides an ultra rigid, and thermally stable machine structure. A unique “box-in-box” design provides superior rigidity, stiffness and agility that is only available in a machine of this caliber.  As will all Mitsui Seiki machines, guideway mounting surfaces are hand-scraped, achieving very high volumetric accuracies. This process is far superior to simply machined and /or ground systems. This engineering and construction concept, coupled with a newly designed machine, now provides users with even more competitive advantages over traditional, similar purpose products.

SKF solves crusher downtime at Aggregate Industries

An innovative engineering solution from SKF is playing an important role in improving the reliability of Pennsylvania rock crushers used by Aggregate Industries at its Torr Works quarry site near Shepton Mallet, Somerset.

 

Aggregate Industries, part of the Holcim Group, is a major UK quarrying business that makes continuous use of Pennsylvania rock crushers at its Torr Works quarry as part of the process of breaking up around six million tonnes of limestone every year. This material is then used in construction projects around the UK.

 

Each crusher incorporates a series of hammers mounted along a central rotor shaft to reduce the limestone to the required size. This process is particularly demanding on shaft bearings, seals and drive mechanisms, with considerable quantities of fine dust being generated. Due to the location of each crusher, limited air movement, and the design of the bearing housing, Aggregate Industries found that machine surfaces became heavily contaminated and that particles of dust were penetrating through the seals. This resulted in severe contamination of shaft and bearing lubricants, which in turn led to increased wear of moving parts, causing unplanned downtime and rising operating costs. The customer’s problems were exacerbated by the poor quality of the castings used in the original bearing housings, which were proven to be porous, allowing oil to leak from the arrangement.

 

Recognising that the solution required a complete refurbishment of the bearing housings and associated parts, Aggregate Industries turned to specialist mechanical engineers, Anstee & Ware. Anstee & Wear partnered with SKF and Antifriction Components, an SKF Authorised Distributor, to provide a custom-engineered solution that enabled the replacement bearing housings and shaft assembly to be manufactured off-site to minimise downtime at the quarry.

 

SKF supplied new housings, each weighing 500kg and being fully tested to ensure that all risk of porosity was eliminated, plus replacement bearings and custom-sized adapter sleeves; the latter were required as the machining required to refurbish the rotor shaft had reduced the effective diameter. In addition, SKF designed a new arrangement of labyrinth and V-ring seals to provide a far higher level of shaft protection against the ingress of dust.

 

Andy Frankham, Sales Manager at Anstee & Ware, explains that, “The refurbished system has now been installed on the Pennsylvania crusher and has been in continuous operation for some months without any problems. As a result, Aggregate Industries now has a custom-engineered solution that is delivering far greater reliability, efficiency and productivity than ever before. This could not have been achieved without the engineering support and technical knowledge provided by the SKF team in the UK.”

 

Aggregate Industries were so pleased with the solution that they have since placed another order to replace the bearing housings on the remaining Pennsylvania crusher.

Automobile exhaust gas particle filter cleaning without separation

New method enables filter cleaning without separation of the supply or extraction pipes
(Bielefeld, 19.05.2015) The soot particle filter in diesel vehicles is full of soot and ash. Does a new one have to be installed? The automobile manufacturers say so, and it can be an expensive issue, which can cost 1000 to 4000 Euros and more, depending on the brand and type of the vehicle. It is much cheaper for diesel drivers to simply arrange for the particle filter to be cleaned. Together with support from the affiliated company mycon GmbH and IROsoft-Cleantech GmbH from Elsterwerda, Kipp Umwelttechnik GmbH has developed a process with which the soot particle filter can be cleaned without any separation.

Cleaning automobile exhaust gas particle filters is already common practice with a variety of systems, such as a CO2 filter cleaning system from mycon GmbH. In addition however, the filter surfaces must be exposed, so supply and extraction lines often need to be dismantled and separated. This means that thermal cleaning, which has be done by IROsoft-Cleantech for years, requires a lot of time. The car filters also need to be separated beforehand and then cauterized several times, which can take several days when blowing out with compressed air and checking the differential pressure. After cleaning, the separating cuts also need to be welded together again. This method is therefore costly and takes time and can also lead to weakening of the exhaust gas system.

Based on a method developed by Kipp Umwelttechnik 18 months ago as part of a sponsorship project on soot particle filter cleaning without separation work, the method has been developed further with the support from mycon and IROsoft-Cleantech. It works with compressed air and a substance, which is introduced into the filter. This substance is non-toxic and can even be drunk, if you can put up with the unpleasant taste. However, the cleaning results of the sponsorship project at the time only reached max. 85%, which made optimization with an additional process step necessary.

Kipp Umwelttechnik incorporated experiences from previous work and plenty of know-how from the practical application of radiation technology in further development of the method. mycon contributed theoretical knowledge in the area of fluid physics and mechanical engineering. IROsoft-Cleantech also provided experience in filter cleaning, specifically concerning the corresponding filters to be cleaned.

An existing prototype system was adapted and put into test operation at IROsoft-Cleantech. The comprehensive expertise brought about the turnaround for optimization of the method surprisingly quickly. The first filters were able to be cleaned thoroughly without separation. The differential pressure test results showed levels similar to those of a new filter. The weight difference between the soiled and cleaned filter also fitted in with IROsoft-Cleantech’s findings over the years. Furthermore, the active cleaning time per filter is less than 10 minutes and cleaning is also fully automatic.

Kipp Umwelttechnik already arranged for the Faculty of Chemistry at Paderborn University to carry out tests on the method in order to establish the parameters that best protect the materials. The analysis showed that the new method from the company displays very good cleaning results, just like the CO2 method used by mycon. The determined results are at least on a par with the established thermal method. With both methods – both the new development and the CO2 method – a function method that protects the catalyst surfaces of the filter channels could be established.

The new method also differs from attempts to clean the filter with water and additives until a cleaning result is achieved.

The respective benefits extend to several areas:

1. Fully automatic cleaning minimizes the sources of errors
2. Unsoiled and gentle cleaning maintains the catalytic qualities of the filter
3. Cleaning without separating and welding work retains the quality of the filter housing
4. Risks of damage, such as caused by fusion during the burning process at temperatures of 550°and more are avoided, since the filters are only treated with a temperature of 350° after the cleaning process
5. Quick cleaning times reduce vehicle downtime
6. The costs for filter cleaning are reduced

The prototype system that has been produced will remain in operation at IROsoft-Cleantech and will be constantly updated in future. Kipp Umwelttechnik and the affiliated company mycon will analyze the experience gained with the prototype system over the next weeks and will start building the first serial systems. The method will be marketed internationally from November of this year. There is already high demand in this rapidly growing market for the new, environmentally-friendly, quick and affordable cleaning method for soot particle filters.

Parker Hannifin Air Saver Units cut energy consumption by 50%

Lichfield, UK, 5th May 2015 – – Parker Hannifin, the global leader in motion and control technologies, has unveiled its innovative Air Saver Unit, which can reduce air consumption by up to 50% and improve efficiency in air blow applications.

Did you know that Air blowing activities consume for almost half of all compressed air used in plants? To help reduce this resource burden, Parker Hannifin’s Air Saver Unit uses pulsed air technology. At its core is a switching valve that converts continuous air blow into pulsed air blow without the need for any additional external control. Put simply, it creates air that is blown in a series of high speed on and off pulses; when the blow is off, there is no air consumption, resulting in fewer tank recharging cycles.

 

side from a sizeable reduction in air consumption, the Air Saver Unit offers other major advantages that include savings in compressor power, a reduction in overall CO2 emissions and a significant contribution to energy-saving activities.

 

The Air Saver Unit is also extremely easy to install. At plants using electrically operated   solenoid valves to control air blowing, the units can be quickly and easily retrofitted to straightaway  deliver a reduction in air consumption with no significant system changes i.e. PLC program reconfiguration. For plants using manual ball valves, there are also passive versions of the Air Saver Unit series; these do not require any electrical power.

 

In total there are seven models in the Air Saver Unit range, offering flows (at 5 bar) from 150 to 15,000 l/min.
