The MAPAL clamping cartridge

The heart of manual HSK clamping technology

An important element of the MAPAL HSK clamping technology is the KS clamping cartridge. The manual clamping mechanism provides maximum clamping forces that can be achieved reliably due to the simple, robust construction. The KS clamping cartridge is used in spindles and basic holders, directly or via adapter flanges. The rigid construction with optimal force application via bayonet and cartridge body to the clamping jaws underlines the effectiveness of the KS clamping cartridges.

The easy assembly of the cartridges via a 90° rotation against a heavy-duty clamping pin ensures secure assembly. The gentle ejection of the tool via the two ejector pins distributes the force and the wear is significantly reduced. The KS clamping cartridges in the designs for full lubrication, high pressure lubrication and MQL are compatible. This feature that makes it easier to re-tool the machine for new machining tasks with different lubrication.

As a universal solution for MQL applications with HSK-A and HSK-C, MAPAL offers the MQL clamping cartridge MQL1. Due to the large central through-bore the aerosol can be transported without loses with optimised flow characteristics. In this way separation of the aerosol is prevented. The cartridge MQL was especially developed for HSK-C. The blind end is minimised by adapting the sealing ring on the face. 

For tight machine compartments with small spindle spacings MAPAL offers the DS clamping cartridge. The programme is completed by the AX cartridge that was especially developed for disc-shaped tools, e.g. grinding wheels and saw blades. With this selection of MAPAL clamping systems it is possible to securely clamp all HSK forms.

Standard design

The standard version of the KS clamping cartridge is the proven all-round model and is suitable for almost all machining situations.

  • High rigidity regardless of the load direction
  • Not susceptible to distorted HSK bases
  • High clamping force way beyond the standard
Design for high pressure applications

The clamping cartridge for high-pressure applications is suitable for coolant pressures up to 150 bar. It is also equipped with an optimised sealing ring for even more reliable sealing of the system.

  • Use up to 150 bar
  • Improves clamping jaw geometry
  • High clamping force way beyond the standard
Design for MQL applications MQL1

As a universal solution for MQL applications with HSK-A and HSK-C, MAPAL offers the MQL1. Due to the large central through-bore the aerosol can be transported without loses with optimised flow characteristics. In this way separation of the aerosol is prevented.

  • Large central through-bore
  • Universal system MQL1 for HSK-A and HSK-C
Design for MQL applications

The cartridge MQL was especially developed for HSK-C. The blind end in this area is minimised by adapting the sealing ring on the face.

  • Large central through-bore
  • With special sealing geometry only for HSK-C
DS diagonal clamping cartridge

The MAPAL diagonal clamping cartridge is designed for usage in tight machine compartments with small spindle spacings. Actuation is using a hex-wrench via a screw positioned at 45°.

  • Convenient actuation with 45° access angle
  • Large central through-bore
  • Clamping forces way beyond the standard
  • Direct mounting in the spindle possible in the HSK nominal diameter
AX axial clamping cartridge

Especially for clamping disc-shaped tools with a central bore, for example grinding wheels or saw blades, also in situations in which the hollow shank taper is behind the tools.

  • Axial access from front and rear
  • Predestined for clamping grinding wheels and saw blade adapters with HSK shank
  • Simple connection contour for direct mounting in the spindle
