Heinz Deitert founded DEPO in 1989 with the objective of realising a more efficient milling technology.

He utilised his extensive experience in the industry to create a complete tool system. The subsequent development of optimal cutting strategies with coordinated tools enables shorter machine run times and ensures a significant increase in productivity in numerous production processes.

The widespread acceptance of the DEPO tooling system enabled the com-pany to establish itself remarkably quickly in the market. Decisive factors here were the level of innovation, flexibility and reliability that DEPO cus-tomers particularly appreciate.

The requirement of offering a “complete package for the toolmaking, moulding and diesinking industry” resulted in the foundation of DEPO Werkzeugmaschinentechnik in 1996.

The development and sale of machine tools and components in con-junction with our milling technology offers all users a high degree of efficiency.The DEPO CAM programming software and milling and strategy training courses complement the holistic corporate concept.

Service is very important for DEPO. Our employees ensure consistent de-velopment, competent advice and planning from the outset, a timely and high quality overall performance and an optimal service.Our staff here are standing by with the latest generation of machining centres, software and our entire tool programme to present you with the latest strategies and products. Come and experience our expertise for yourself.Make an appointment and come and visit us. We would be happy to provide you with information and advice.

Milling system 54 for square indexable inserts

The term HFC = High Feed Cutting means milling with extremely high feed rates of up to 3 mm/tooth, which leads to an enor-mous material removal rate and thus great economic efficiency.

The special design of the cutting edge and tool geometry ensures that a large proportion of the cutting forces that arise are directed in the direction of the machine spindle axis and that the radially acting components that cause vibrations are minimised. The design of the soft-cutting chipformer geometries reduces cutting forces and machining noises, which can be observed in a remarkably quiet and low-vibration operating behaviour compared to other systems.

In order to cover all tool diameters from Ø 16 to Ø 80 mm with economical application parameters, the indexable inserts are available in three different sizes.

Four effective cutting edges are available per indexable insert.

To optimize the axial and radial run-out, equip the tools so that the operating cutting edges always have the same corner markings.

When using the tools, it must be ensured that the maximum cutting depth apmax is not exceeded.For problem-free and collision-free milling path calculation in the CAM systems, the radius to be programmed is Rprog. decisive.

The two values can be found in the tool tables.

The system is suitable for the following applications:

Handling of the fastening screw C 80300DS (differential screw):

The fastening screw C 80300DS has a fine thread on one side and a regular thread on the other.

1. Screw the fine thread into the cutter body up to a light stop (delivery condition)

2. Place the milling cutter on the journal of the holder, leaving a gap of approx. 4 mm between the planes. Otherwise, readjustment can be made by turning the clamping screw by 0.5 mm per revolution.

3. Screw the clamping screw into the mount and tighten it [15 Nm].
