The Junker Quickpoint process: economy with aim
June 11, 2009
Can integrate the rectification Junker modules modified with various bodies, machines Quickpoint be equipped for a grinding, as rectified profile, punzador, notching and thread of tightening a single subject of the piece.
This process Quickpoint, which was developed more than 20 years ago, opens a new dimension to the profitability, exceeding in productivity and versatility to any other process of grinding, in particular for automotive parts. That is why qualified technicians in Nordrach, with their long years of experience and broad 'know-how', continued the Quickpoint process.
Reduced grinding forces
The point contact of grinding has special advantages. QUICKPOINT uses a body of CBN or diamond of extremely low wear and a width of only few millimeters while the inclination of the axis of the body with respect to the horizontal axis of the piece creates a free angle, thus reducing the contact line to a point. In this way, minimizing the forces favoring the grinding of thin and sensitive parts.
QUICKPOINT allows complete grinding of edges and extreme levels on both sides, cones, chamfers, radii, fest, carved, you thread, levels and multiple edges, also at both ends of the piece, without change of body and a single subject. In addition, no annoying tows are required. They are especially high speeds of Court up to 140 meters per second are achieved with the Quickpoint bodies. These speeds can also rectify materials such as ceramic or titanium.Also, a long life without revived of the bodies of cbn means reduced maintenance times. Thus, the productive use of machines Quickpoint reaches up to 95%.
The smaller models reach a broad spectrum of individual production and mass pieces
Machines Quickpoint 1000 series, with a height of tip of 100 mm and a length of subject and grinding of 150, are ideal for complete grinding of small Rotationally symmetrical parts up to 5 kilos. The Quickpoint 1000/10 version, with a spindle fixed portamuela and a body, is designed for external cylindrical grinding. The Quickpoint 1000/20 version with its screw pivotable portamuela in 15th to rectify edges and cones as well as rights and left flat ends under certain conditions. The third version with two bodies displaced each other allows also the grinding without limitations of rights and left flat ends.
Five variants of head spindle portamuela for universal and versatile jobs in large series and small batches
The Quickpoint 3000 series offers a very universal use, with a height of tip of 150 mm and a length of subject and grinding of 500 for parts up to 10 kg. In addition to the aforementioned versions of the Quickpoint 1000 series are the Quickpoint 3000/40 and the Quickpoint 3000/60. The first has a spindle portamuela that can swing in 180 ° and 15 ° at the level of work. Thus, these machines can rectify pieces in its full length until its ends as well as rights and left flat edges without limitation.
The Quickpoint 3000/60 version has three portamuela spindles displaced between 120 ° and pivotables. Allows you to correct an external cylindrical body, one of punching/fitted or screwed a piece all geometries in rapid sequence in a single subject. This grinding allows the factories of the automotive industry minimize their times and increase the quality of the products.
Great versatility in large families of parts
The Quickpoint 5000 series offers the advantages of this process to pieces up to 70 kilograms, a length up to 1200 mm and a diameter up to 170. The machines can react quickly in the elaboration of parts in large families and small and medium batch sizes. Head of screw portamuela 10 versions, are available for the great Quickpoint 5000 series 20, 40 and 50.
Equality structures minimises the work and costs. The similar structures of machines in all three series mean advantages for the user. For example, the information you enter through the Erwin Junker Operator Panel EJ-OP. platform Its advantages lie in graphical representation, interactive developments in programming and operation, the reduced need for training and a re-equipment and quick adjustment. Once trained, employees are able to operate all machines Quickpoint for all three series.
Other equal to three series features provide high accuracy and low times of equipment. It is worth mentioning here the patented tripuntal system of accommodation of bodies, accommodation and scuffs. These are held without much adjustment, giving an accuracy of 1 micron round March, approximately. Balanced automatic systems incorporated in the housing of the body give an optimal progress also with high revolutions.
