Reaming becomes a high-performance process
High-precision holes with tightest tolerances and perfect surface quality are usually produced by reaming. This process has always been very slow and is therefore not very popular in our fast-paced world.
Our new high-performance reamers, however, significantly speed up your reaming process by allowing for maximum cutting values.
- Highest process reliability
- Considerable reduction of processing time
- Maximum service life
- Specifically for the materials used in mould and die making
- Use in hardened materials at 67 HRC
Our carbide high-performance drills
With our high-performance drills you are ideally equipped for machining everything from soft materials to hardened steels. They ensure maximum cutting values and service life.
Advantages:
- Highest cutting values and service life
- Best surfaces and very high accuracy
- High process reliability
- Very precise drilling behaviour
- Perfectly coordinated to the materials used in mould and die making
Important application criteria
Our range of high-performance drills is perfectly matched to the high-quality materials used in mould and die making. The deep hole drills are best suited for making the holes for cooling systems. In order to achieve a perfect result, we have put together a few tips for use.
Cutting values
Practice-oriented cutting values can easily be found in our cutting data calculator. With just a few clicks you have the application data for a wide range of materials. In the Meusburger portal, you will find the most important materials and the matching cutting values in a table.
Tool clamping
To achieve the best results in terms of concentricity, we recommend shrink fit and hydraulic expansion chucks for the carbide drills. Under optimum conditions, fitting accuracy (IT7–IT8) is possible. In combination with the very good surface quality achieved by the drills, reaming is often unnecessary.
Cutting fluids
For carbide drills with inner coolant supply, we recommend a coolant pressure of 15 to 20 bar. Higher pressures of up to 40 bar are recommended for deep hole drills. With the correct coolant pressure, the hole can be drilled to the final drilling depth in one operation. A chip removal process should be avoided, because if chips are flushed into the hole, they increase the risk of breakage.
Drilling into solid material
Our carbide drills up to 8xD are suitable for drilling into solid material. For carbide drills from 12xD (WZB 10227) we recommend a pilot hole. Our carbide NC-centre drill WZB 114446 with an angle of 142° is best suited for centring.
Maximum drilling depth
A chip jam can cause tool breakage. To avoid this, a safe distance must be maintained between the groove outlet and the workpiece. In the table in the Meusburger portal, this value is indicated under ‘T max.’ for each tool. Maintaining this safety distance increases process reliability during drilling.
Interrupted cross section
The feed rate must be reduced for transverse holes.
