Multi-Spindle 3-Axis Knee-Type Gundrilling Machines for Off-Center Drilling – Mollart Omnisprint

The Mollart multi-axis knee-type Omnisprint deep hole drilling machine range has off-center hole drilling capability with a drilling range between 2mm and 22mm diameter and up to 1,000mm in depth with 1, 2, 4 & 6-spindle configurations, depending on the drill diameter specification. All Mollart machines will be fitted with Fanuc CNC control and its process monitoring.

The Mollart Omnisprint has many users in the Glass Bottle Mould and Automotive Industries. The machines are used to gundrill bottle moulds, mould plates, transmission shafts, and valve bodies coolant holes for through coolant tooling. Furthermore, we designed and manufactured the machine fixturing, providing a complete turnkey solution to manufacture hydraulically powered drive shafts used in earth-moving equipment and automatic gearboxes. Many machines are robot-fed and are part of a manufacturing cell.  We have integrated our machines with multiple robot systems and can offer a full turnkey supply.

Typical Applications

  • Bottle moulds
  • Mould plates
  • Transmission shafts
  • Hydraulically powered driveshafts
  • Valve bodies

We can help you achieve better drilling results

Solving customer production problems is just one of the highly specialized services we provide at Mollart Engineering. Here is an example of how our drilling expertise was used to solve an actual customer’s off-center deep hole drilling problem.

The Mollart Multi-spindle 4-Axis Knee Type Omnisprint Machine

This machine was designed and engineered for off-center deep hole drilling. Having the right machine can make a huge difference to your production result. This project was for parts with a total length of 1 meter and needed to be drilled with 5mm and 6mm holes from both sides with special HP solid carbide tools from Botek. Working with the maximum length available for this type of tool, Mollart was able to maintain true position in comparison to one of our competitors. The feed rates for this tool were from 120mm – 150mm per min. 

We find solutions to suit your needs and strive to produce the best results possible, enabling you to grow your business and move forward. We’ve helped many companies around the world solve their drilling problems and have worked with a wide variety of sectors.
