Motor-spindle protection system MS³

Stops collision damage to machine tools

Collisions in machine tools have many causes:

  • Operating and programming errors
  • Interfering contours
  • Incorrectly set zero points
  • Power failure

In practice, collisions therefore often occur when a CNC program is executed for the first time.

To prevent damage, the MS³ motor-spindle protection system offers the best possible safety for the CNC machine tool.

The advantages

  • Protected machine tool and motor spindle
  • Maintaining machine accuracy
  • Full availability
  • After the crash: restart and calibration without a long standstill

The facts

  • The protection that is always active
  • Unlimited roughing performance
  • Maintenance-free and indestructible
  • Adaptable to all common motor spindles

Protect your investment

A collision without protection means

  • Motor spindle damaged
  • Machine accuracy adjusted
  • Production interruption
  • High repair costs

The MS³ crash protection from Jakob offers

  • Multi-level protection through emergency stop signal, power flow interruption of the motor spindle and additional braking distance of the feed axis
  • No interruption to production
  • Absorption of collision energy
  • Protection in all axial directions
  • Responsive action

The structure of the MS³ motor-spindle protection system

  • Integrated double flange system with connection to spindle and machine
  • Magnets in the joint ensure high holding force and rigidity
  • Suspension for shock absorption and automatic return of the motor spindle
  • Joint design ensures high re-engagement precision

The protective function

Magnets ensure cohesion in the MS³ motor-spindle protection system. In a collision situation, i.e. when a critical overload force is reached, the protection system interrupts the force curve of the motor spindle and machine and effectively dampens the impact. As a result, the damage-relevant force peaks of the collision do not affect the shock-sensitive components of the motor spindle, such as the ball bearings.

Due to the additional axial or radial deflection of the spindle, depending on the overload, the axis drives of the machine gain the necessary braking distance for automatic emergency braking from high processing speeds.

Replacement and repair of the spindle are avoided. The geometry of the machine is not adjusted. The MS³ protection system functions independently of direction and non-destructively. After the axes are released, the protective system returns to its starting position and the machine can continue production.

Voices from the field

“On average, there are 2-3 collisions during the service life of the machine tool.”

“The investment in MS³ pays off with the very first collision.”

“It actually works!”

100% machine availability guaranteed after collision!
