1. Subframe machining:
Hidden stability

Although it is hidden, the subframe has numerous tasks to contend with and bears the same responsibility as the other wheel suspension components. Engineered with a lightweight design, its structure is becoming more complex and the materials more challenging. To ensure it can still be machined efficiently and quickly, our special tools often combine several process steps in one.

1. Roughing boring bar

Pre-machining tool for the main rubber bearing holes

  • Indexable inserts with TiB² coating for high cutting speeds and feeds
  • Indexable inserts positioned as a stepped tool for:
  • Improved chip control
  • Lower cutting forces
  • No bending of the long subframe arms
  • PCD indexable inserts also available

2. PCD milling cutter

Multi-purpose PCD milling tool for flat surfaces and pre-machining

  • Optimum productivity
  • High feeds and cutting speeds can be achieved
  • Very sturdy shank design and very long cutting edges

3. PCD special multi-purpose tool

  • PCD special tool combining several machining steps
  • Finishing of the rubber bearing hole
  • Forward and reverse face milling
  • Chamfer machining to allow bearings to be pressed-in


2. Transverse link machining:
Keeping you on the straight and narrow

The transverse link plays an important role in terms of a vehicle's safety, control and driving comfort, and is continuously subjected to enormous loads. For this reason, only tough, corrosion-resistant materials can be used that also mustn't drive up the weight. Are they easy to machine? Not really, but with our specialist tool solutions your costs will also stay on track.

1. Roughing ­& finishing boring bar

Pre-machining and finishing tool for the rubber bearing hole

  • Drilling of the transverse link with our Pentron indexable insert
  • Finishing with our 3D-printed PCD cartridges

  • Lowers tool costs

2. U­-axis

  • Reduces the cost per part
  • High repeatability

3. Special stepped drill

Roughing boring bar for machining the ball head

  • Drilling with our standard Pentron indexable inserts
  • Several contours can be formed at the same time, internal diameter, flat surface and external curve chamfer
  • Many different geometries and indexable inserts for steel & aluminium available


3. Wheel bearing housing machining:
Complex shapes are a challenge for the tool and machine

The complex geometries of a wheel bearing housing made of aluminium alloys often pose a challenge for many machine operators. For example, the milling and drilling operations in the bearing seat have to be increasingly process-secure, accurate and efficient, as they account for a significant proportion of the production time. The sheer variety of cylindrical, conical or spherical holes call for state-of-the-art machining centres and precision drills to ensure optimum machining.

The ideal solutions for the latter can be ordered from stock.

4. Roller bearing machining:
Speed things up with the Swiss army knife of cutting tools

Roller bearings are used wherever components rotate at high speed or heavy loads need to be set in rotational motion. Their simple design – inner ring, outer ring and rolling element – belies the sophisticated functions and high quality standards of these components. And the tool systems used must be up to the job, so that stringent requirements relating to service life and precision are met during the machining of these complex parts.

Whether it is grooving, turning, drilling or all these things with a single tool, the CERATIZIT Group supports you in optimising your processes with multi-talented tools.

5. Wheel hub machining:
Precision and a long service life that turn things to your advantage

It is often assumed that a wheel hub is an easy-to-produce turned part. However, producing these components from tempered steel as efficiently and precisely as possible requires long tool life. If wheel hubs made of case hardened material are specified, then in-depth expertise and intensive development work are needed to create the tool's cutting edge, in order to ensure continued precision and a long service life.
