P/M (Powder Metallurgy) Sizing Press
Customer Needs Shape the GRABENER Product Range.
The GRABENER press system is specially designed to produce precision parts. It operates with a knuckle-joint mechanism, trusted a thousandfold, with the press frame assuming the function of a ram.
The ultra-high rigidity of the press gives users the assurance that the manufactured parts feature the reliable, uniform quality that satisfies customers.
GRABENER has acquired a wealth of know-how in the design and manufacture of knuckle-joint and other press systems. All those skills and experience have been invested in the company's sizing presses.
The presses are tailored exactly to customer needs. Whatever your requirements, be they for a standard-type press or a one-off custom-designed press system, you can be sure GRABENER will meet them.
GRABENER sizing presses give you solid and reliable service. They are noted for exceptional availability and long life.
Responding to each and every customer's requirements.
GRABENER sizing presses are equipped with a standard single-stage adapter. The die is float-mounted on a hydraulic pad in order to ensure that the metal powder is compressed at uniform density in the workpiece.
As a special variant, we supply a multi-stage adapter to accelerate production of highly intricate parts. This allows you to perform three finishing steps in a single operation on the same press. Giving you a significant cost advantage.
Greater flexibility with easy re-tooling
Good access to adapter section makes tool change and set up fast and easy.
Tool change is accomplished with hydraulically operated roller rails and a hydraulic insert and withdrawal cylinder. The adapter is simply pushed onto a roller table to be moved in and out of the press. This allows you to produce even small batches economically, and gives you the flexibility to respond to individual customer requirements.
The GRABENER System Solution
Peripheral components turn a universal press into a special, individualised press system.
GRABENER machine technology gives you everything: From planning, development and design right through to production and installation of a complete knuckle-joint zizing press. Customers receive systems custom-designed for their specific needs. And, the GRABENER project team stays on hand with advice and support when a system is up operating on the workshop floor.
Efficient and economical
With the new multi-stage sizing system from GRABENER, we can now complete several production steps in a single pass through the press.
Edge-rounding, precision sizing and bevelling have become a single manufacturing operation In a word: we now have only one press to do the work of three.
The GRABENER system is equipped with a feed buffer belt for four minutes of continuous press operation, an integrated lubrication tank, a fully automatic workpiece aligning and control station, and a transfer feed device with an electronic monitor.
Integrated lubrication saves the time and expense previously spent doing the job outside the press.
Comprehensive system solution for sizing sintered parts
The nucleus of the system is a mechanically driven knuckle-joint sizing press equipped with a mechanical ejector and a multi-stage sizing adapter. Completing the system is a delivery belt and an adapter change-and-clamping device. The tool adapter is an innovative development giving the operator better access. It helps reduce set-up times during frequent changes on small-batch production.
Output up fourfold with one man
With this system, integrating three different manufacturing operations, a single operator can turn out 30 sintered parts per minute on an 800-ton press. Three production units were previously required for a similar output, and none of the three was capable of producing more than 20 parts per minute.
Greater competitive thrust from cost advantage
The modern GRABENER press system reduces manning levels and speeds up production. The resultant cost advantage gives the sintered-sizing operation a crucial competitive edge over other methods. By lowering wage and labour costs, the GRABENER system puts manufacturers in a position to carve a larger slice of their market.
