Deep Drilling Machines

TBM (Standard Deep Drilling Machine)

The standard deep drilling machine is characterized by its simple, robust and compact design system. A high drive power with corresponding torque as well as a wide speed range guarantee an optimal utilization of the machine capacity. The deep drilling machine is suitable for the ELB and BTA method as well as combined methods. In addition, this machine can be used to produce hydraulic cylinder tubes by using peeling and smooth rolling tools. The modular system that Unior has been using for years guarantees all desired machine variants and enables the shortest possible delivery times.

Applicability

The machines are mostly intended for rotary workpieces, as they enable rotation in reverse direction of the workpiece for bigger level of boreholes exactitude. Modification with coordinate table enables processing of also smaller cubic workpieces.

Advantages

  • optimal cutting performance
  • high bore quality, with regard to diameter tolerance, surface quality and geometrical shape accuracy
  • high concentricity, minimal bore deviation
  • low burr formation during drilling and when over drilling and of cross drillings
  • stepless spindle drives

Applicability

The additional B-axis allows the workpieces to be positioned in any desired position to enable the machining of several bores without re-clamping. With this machine design, high accuracy requirements are achieved with good bore quality, which is why the KTBM is the best solution for precise coordinate drilling.

Advantages

  • machining of cubic and cylindrical pieces
  • high precision and surface quality
  • designed as a universal machine and can be obtained as an ELB or BTA deep-drilling unit
  • cylindrical workpieces can be drilled with counterrotating tailstock
  • pilot hole can also be made with end mills with r=50mm

STBM (Special Deep Drilling Machine)

Our special deep drilling machines are individually designed to meet the requirements of the customer. The machines offer optimum cutting performance and drilling quality while maintaining diameter, surface and shape tolerances. The serial production requires special machines, also in multi-spindle design, with equipment for automatic operation and workpiece change to reduce non-productive time.

Description

  • large drilling depth in the drilling cycle (up to 250 times the diameter)
  • Special deep drilling machines with several spindles
  • Integration of deep hole drilling in a special machine

Technical data

Special deep drilling machines with several spindles

  • simultaneous machining of several workpieces or simultaneous machining from different sides.

Integration of deep hole drilling in a special machine

  • e.g. combination of drilling, milling, turning and thread cutting with deep hole drilling

We have the necessary experience and, thanks to our highly qualified staff, we are able to provide technical and technological solutions for your needs, for serial productions. Together with world-renowned cutting tool manufacturers, the prerequisites for the for a stable working process, a long service life of the machine tools and good service life of the tools is created. Entrust us with your special application and we are convinced that we can requirement to be solved optimally. 

Applicability

Our special deep drilling machines are specially designed for the workpiece to be produced. Possible workpieces are camshafts, crankshafts, common rails and cylinder heads. Together with world-renowned cutting tool manufacturers, the prerequisites for the for a stable working process, a long service life of the machine tools and good service life of the tools is created.

 

Advantages

  • large drilling depth in the drilling cycle (up to 250 times the diameter)
  • very good cooling and lubrication conditions
  • minimum bore run-out
  • by deep drilling other operations can be partly saved
  • materials that are difficult to machine can be drilled
