Example 1
Machining centre
Task
| Sector: | Machine tools |
| Machine name / machine function: | Machining centre |
| Drive name / drive function: | 3 different axes with preferably the same drive |
| Ambient conditions / special requirements/ regulations: | Machine tool environment; liquid oil mist |
| Installation situation / available installation area: | Very small installation area |
Solution
| Information about gear type or the transmission element: | Ball-type linear drives provided by the customer, i.e. the customer can use so far used and proven makes |
| Rated and maximum torques: | 80 Nm / max. 170 Nm |
| Rated/maximum speed: | 3,000 rpm |
| Spindle pitch / gear reduction: | 10 mm |
| Compression: | max. 25 kN |
| Cycle rates / operating mode: | S3-60 % ED |
| Place of installation: | Directly on KR axles, very compact |
Customer benefits
As a result of the directly matched hollow-shaft motor drive the dynamics were extended to such an extent that production figures for this machining centre have risen significantly. The stiffness of the drive systems was also improved, resulting in a more reliable processing accuracy. Two horizontal axes can be operated by the same drive. The third drive for the vertical axis was only completed by the installation of an electromagnetic safety holding brake (resulting in a type reduction).
