Spindle Technology – Series 700
Internal grinding spindles
Main features series 700
- Mounting taper for pulley
- High bearing rigidity
- Preloaded spindle bearings
The series 700 internal grinding spindles are used for applications when higher cutting speeds are required. All rotating components are finely balanced.
Special materials, which guarantee high dimensional stability even under extreme conditions, are used to manufacture our grinding spindles.
Only high precision preloaded bearings are used. The mounting taper concentricity is < 0.002 mm.
The technology of the 700 series
For internal grinding spindles with internal taper 1:7.5, the appropriate direction of rotation must be determined. Internal grinding spindles with an HSK chuck can be used for both clockwise and CCW rotation. This requires use of our own brand accessories.
Lifetime grease lubrication
The tool side is sealed by a specifically proven labyrinth packing. This protects the spindle bearings against soiling. Spindles can be installed either horizontally or vertically.
Operating instructions, operating tools
The tools are attached using the internal taper or manual HSK chuck
