The Henninger Spindle Speeders of the 832 & 834 series
The Henninger spindle speeders reach new records in the industry. There are many possible applications for the new spindle speeders. Especially where cutting tools are becoming more and more filigree and sophisticated. Here, ever finer milling and grinding tools have to be used in the machine tools.
The Henninger spindle speeders offer a transmission ratio of up to 1:7.7 at a maximum of 50,000 min-1. In this way, tools that require high cutting data can be fully utilised. While, at the same time, the machine spindle runs at a reduced speed. This lowers the temperature rise, hence the required cooling capacity. The energy costs for the machine decrease. The spindle speeder continues to offer a variety of advantages, such as through the modular drive taper system, which enables adaptation to different machines of the customer. With an adapted stop- and arrester attachment, automatic replacement is also feasible.
In addition, the medium can be brought directly to the cutting edges of the tool by means of an internal coolant supply. Thus, the spindle speeder is a tool that can bring high benefits to many machines.

For which applications are Henninger Spindle Speeders used by our customers?
Typical applications include: production of electrodes, production of fine and micro drillings, line-off of moulds, finishing of workpieces, machining of hardened material, dry machining, grooving, slot drilling, deep hole drilling, grinding and deburring.
In order to be able to offer even the smallest grinding tools the necessary performance, ANCA, for example, uses our high-speed spindle 832 in its tool grinding machines. This is equipped with a coolant ring in addition to the ANCA-specific tool interface. ANCA’s full experience report can be read here.
Milling with Ceramic Cutters
The Henninger spindle speeders are also ideal for ceramic milling cutters that require high speeds. This makes it possible to adapt machines with too low speeds to high-performance milling cutters.
