Diebold supplies powerful high-frequency spindles and spindle units to the best-known machine manufacturers in Germany, Europe, the USA and Asia for use in aerospace, mold industry, automotive and general production. The current capacity is more than 2,000 spindle shafts and components per month.
Our product range includes motor spindles for HPC milling (High Performance Cutting) and HSC milling (High Speed Cutting). A particular specialty are spindles for 5-axis machines, swiveingl spindles with extremely short design and high power (up to 90 kW) and high speeds (up to 50,000 rpm).
In the high-performance sector, machine manufacturers are using high-frequency spindles with modern equipment in terms of frequency control, vibration control, sensor technology, unclamp units and through coolant capabilities. Diebold spindles meet these challenges at the highest quality level. Depending on your requirements, we supply spindles with rotary unions for coolant, MMS, ATS, cryogene cooling or only air. We offer models with vacuum suction through the spindle and we have various models with HSK-T taper and spindle clamping for turning operations with the HSK-T interface.
Diebold offers service-friendly and economical HSK plug-in spindles for high-performance milling. This innovative spindle concept impresses with its compact design and grease bearings, which offers significant cost savings compared to the more complex oil-air lubrication.
The spindle is designed as a plug-in spindle and can be replaced quickly and easy. The shape of the housing is freely selectable:
The spindle has low imbalance due to the very precisely manufactured individual parts. The clever cooling reduces the axial growth to a minimum.
With an output of 41 kW and up to 15,000 rpm, these spindle models are ideal for demanding machining operations on stable machining centers or turn/mill machines. Hydraulic clamping of the spindle shaft allows turning operations with tool holders HSK-T. We use grease lubricated bearings. Therefore the machine tool builder is savings cost for the equipment of the machine, as the more complex oil-air lubrication is not necessary. The spindles have low imbalance due to the very precisely manufactured individual parts and the axial growth of the spindle shaft is reduced to a minimum due to clever cooling.
Our modular series of high-frequency spindles with diameters of 80 mm, 100 mm and 120 mm for high-precision machines can be equipped with different taper variants (HSK-A, HSK-C, HSK-E, HSK-T).
The modular system allows you to choose from a wide range of variants.
According to your individual requirements, we offer spindle packages consisting of several assemblies. For example, spindle shafts with integrated drawbar systems or spindle shaft, clamping system, bearings and rotor.
Only the best materials and components are used for the production of the spindles. We work together with the leading manufacturers of clamping systems to offer you state-of-the-art tool gripper systems.
We use the Ott-Jakob system for automatic tool change and the brands Mapal, Gühring and Sigma for manual tool clamping.
By combining our spindles with the world´s most proven clamping systems, we are able to provide you with high-quality technical solutions unrivalled in the industry.
The many years of experience of our in-house trained assembly and service employees guarantee compliance with your quality requirements. Our assembly staff are regularly trained for the correct use of all components and systems of our suppliers.
Spindle repairs are an important part of our spindle technology.
Our comprehensively trained service staff repair Diebold high-frequency spindles as well as spindles from other manufacturers. The spindle repair includes the replacement of the bearings, reworking of the tool clamping system, regrinding of the spindle taper, the test run and the full documentation of the spindle repair.
