BTA-Skiving Tool
- Skiving tool for deep hole drilling for the diameter range Ø40 - 210 mm

- The tools have a removable cartrige. In the cartrige the holders for the opposite skiving inserts are arranged.

- The tools are adjustable and can be adapted very precisely to the desired machining diameter.

- For machining, the inserts are extended hydraulically. They can be retracted again after machining. This allows the tool to be retracted from the bore without scoring.

The tools have a pre-cutter and an arc insert as final cutters.

- The skiving tools are guided in the bore via fibre pads.

Boring bars
Boring bar clamping unit
Two drill tube clamping units are available for clamping the boring bar in the deep hole drilling machine. A collet chuck system is used to clamp smaller drill tubes. The precise centric clamping as well as the high clamping forces are especially necessary for boring bars up to a diameter of 47 mm.

Larger boring bars are clamped with a split bush system that reaches up to a diameter of 154 mm as standard.

Skiving and roller burnishing tool
BTA-Tiefbohrsysteme GmbH
Roller finishing and deep rolling tools
Combined tools
Skiving and roller burnishing tools are used for the economical machining of hydraulic cylinders.

The upstream skiving process sets the required diameter (IT6 possible) and the subsequent roller burnishing process levels the surface.

Both a flexible tool and a rigid version are available depending on the workpiece to be machined.

Oil pressure head
For deep drilling according to the BTA system, BTA-Tiefbohrsysteme offer a range of different BOZA. The oil pressure head has four main functions:

- Supply of the cooling lubricant to the tool
- Sealing of the workpiece
- Centering and holding the required guide bush
- Sealing of the drill pipe

The different BOZA types are designed to fulfil these functions according to the requirements of the machine. This applies both to the workpiece clamping and to the machining method. For example, rotation-symmetric workpieces can be machined with only a rotating tool, only a rotating workpiece or both rotating in reverse.
