INSERT HOLDER SETS
CHISEL SETS FOR THE PPE MACHINES
The chisel sets for the PPE machines have been specially developed to process all pipe sizes within the reach of the machines. Without the time-consuming adjustment of the chisels. The chisel sets consist of insert holders that are equipped with hard metal inserts. These inserts are suitable for processing various materials. The chisel sets are supplied with a so-called adjusting cone, which makes it possible to adjust the chisels in the right way quickly and easily. The tool sets are supplied as standard in a 30 ° or 37.5 ° version. Other angular positions are available on request
PPE-6 chisel set
The 30 ° chisel set of the PBM-6 machine consists of three insert holders. One holder is provided with one insert; two holders are provided with two inserts. The 37.5 ° chisel set consists of two single and two double insert holders. The table below provides an overview of the insert holders and the pipe sizes that can be processed with it. As an example: insert holder no. 1 processes a pipe diameter of 30 mm to 1.5 "and insert holder no. 2 processes a pipe diameter of 1.5" to 3 ".
|Insert plate holder nr. 1||ø30 mm till ø1,5" (ø48 mm)|
|Insert plate holder nr. 2||ø1,5" till ø3"|
|Insert plate holder nr. 3||ø3" till ø4"|
|Insert plate holder nr. 4||ø4" till ø5"|
|Insert plate holder nr. 1-2||ø6"|
PPE-16 chisel set
The PBM-16 machine's chisel set consists of 2 double inserts and 2 three double inserts, each with two / three inserts. The table below provides an overview of the insert holders and the pipe sizes that can be processed with it. For example: insert holder No. 2 processes a pipe diameter of 2 "to 3" and the second insert processes 8 ". Insert holder No. 4 processes the pipe diameter 5" and the second insert of insert holder No. 4, machined pipe diameter 12 ".
|Holder||Pipe diameter||Holder||Pipe diameter|
|Insert plate holder nr. 1||2" till 3"||Insert plate holder nr. 1-2||8" till 16"|
|Insert plate holder nr. 2||3" till 4"||Insert plate holder nr. 2-2||10"|
|Insert plate holder nr. 3||4" till 5"||Insert plate holder nr. 3-2||12"|
|Insert plate holder nr. 4||2" and 6"||Insert plate holder nr. 4-2||14"|
Processing wall thicknesses larger than 12 mm.
For machining wall thicknesses larger than 12 mm you must mount two or more chisels "one above the other". Special insert holders are required for this operation. The situation then becomes the same as in the drawing (for example No. 1 + No. 2).
We also develop customized 'specials', in line with your wishes and requirements.
The pipe is clamped with a self-centering prism clamp (for which no spare parts are needed). The prism clamp can handle the entire clamping range of the machine. The specially developed chisel set allows the machining of all pipe sizes within the range of the machine. Without having to adjust chisels again and again.
Thanks to the stability of the machines, every finishing operation is the same. This promotes the welding result, which is of the greatest importance when welding with, for example, a welding robot.
The table below gives a few processing times that were measured during the making of a weld seam pre-treatment of 30 °. Naturally, several types of final operations can be performed. It is also possible to do a combination of different final edits simultaneously.
|pipe diameter||Wall thickness||Material||Processing time|
|4"||-||114,3 mm.||6||mm.||St. 37||ca. 15 sec.|
|6"||-||168,3 mm.||12||mm.||St. 37||ca. 30 sec.|
