Open the catalog to page 1History of Th. Wortelboer BV Th. Wortelboer BV was established in 1946 as a technical trading company. The delivery programme developed more and more in the direction of pipe constructions from 1965. Since then Th. Wortelboer BV has specialised in supplying and later manufacturing of the required tools and machines for piping constructions and pipe end preparation. Quality, a long lifetime, ease of operation and naturally the wishes of the customer are the most important design requirements. Machines that are designed by Th. Wortelboer BV are characterised by their enormous operational...

Open the catalog to page 3PBM-4, PBM-6, PBM-12 and PBM-16 The basis of the PBM series is formed by the new PBM-4 with clamping range from 1/2” to 4” (20 mm 116 mm outside diameter). The number in the title of the machine refers to the maximum clamping range in inches for that particular machine. For example, the PBM-16 has a clamping range up to 16” (410 mm). A complete overview with specifications of all PBM machines can be found in the middle of this brochure. PBM-12 MAKING WELD PREPARATIONS IS A MATTER OF SECONDS The performance determines the choice of a machine. Th. Wortelboer BV supplies the fastest working...
Open the catalog to page 4PBM-24 and PBM-30 The PBM-30 pipe end preparation machine is (at present) the largest in the range of PBM machines. Because of the size of the machine and the weight of the clamp both the PBM-24 and the PBM-30 are supplied standard with both an electrically driven feed and an electrically operated clamp. The insert holders of the largest PBM machines are suitable for carbide inserts with a cutting length of 45 mm. Thanks to the robust way in which these heavy PBM machines are constructed a feed of no less than 0.4 mm (or even more) per revolution is not the slightest problem. This reduces...

Open the catalog to page 7Copying system for PBM machines A copying system can be supplied for the PBM-12, PBM-16, PBM-24 and PBM-30. The copying system allows thin-walled and/or non-round pipes to be machined very precisely and the desired end preparation edge can be made despite the fact that the material is not round. The copying system can be fitted to existing machines (PBM-12, PBM-16, PBM-24 or PBM-30). The original tool head is replaced in that case by a tool head with the copying system that is mounted directly on the main shaft. The tool head with copying system for the PBM-12 and PBM-16 has a single...
Open the catalog to page 8Roller benches type TRB The TRB roller benches have been especially designed for use in combination with the PBM pipe end preparation machines. The trough system with steel rollers makes it possible to roll the pipe easily by hand into the machine. Just as the PBM machines the TRB roller benches are extra strong and robust and exceptionally suitable for heavy work. Unusual sizes or modified models, for example with stainless steel rollers or completely turneable through 180°, are available on request. All PBM machines are provided with an extra 400 Volt socket in which the roller bench...
Open the catalog to page 9Insert holder sets for PBM machines Th. Wortelboer BV has developed unique carbide insert holders and carbide inserts for the PBM machines. INSERT HOLDER SETS FOR THE PBM-12 The insert holder sets for the PBM-12 machines consist of four insert holders each with two inserts. The drawing gives an overview of the insert holders and the pipe sizes that can be machined with the particular set. Each separate insert is positioned in such a way that it can machine a particular size of pipe while the other inserts in effect rotate without doing any work. A set of four insert holders, called an...
Open the catalog to page 10Insert holder sets for PBM machines Below some possibilities of insert holders and (special) inserts. Insert holder for facing Insert holders for beveling “above” each other (wall max. 25 mm) Standard insert with cutting length of 16 mm Custom made insert holder and special insert
Open the catalog to page 11PBM specials As well as the standard series of PBM machines Th. Wortelboer BV also supplies special models designed according to specific customer wishes and requirements. The photo on the left shows a PBM-6 machine that has been designed as a semi-automatic machine. The pipes are positioned in the machine manually up to the pipe-stop. One push on the button causes the pipe to be clamped, the stop to slide back and the rotating cutting head to move towards the material. Once the end preparation has been made the cutting head moves back to its starting position, the machine stops, the...
