Suhner spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Suhner spindles and motor spindles — the Swiss industrial group known for its precision machining spindles, with the SPINDLEmaster range used in automotive, aerospace and mechanical engineering. Not to be confused with Sunnen, the American honing machine manufacturer, which has its own separate page.
Suhner, a Swiss group known for its precision machining spindles
TLDR: SUHNER Machining, a division of the Swiss Suhner group, designs precision machining spindles for the highest demands in concentricity, speed and power, with sites in Switzerland (Lupfig), Germany (Bad Säckingen) and the United States, serving the automotive and aerospace industries.
The Swiss Suhner group, known for its machining spindles and technical expertise, covers through its SUHNER Machining division the design of precision machining spindles for the most demanding applications in terms of concentricity, speed and power. Spindles are critical components in the various machines used in industrial production: rotating axes holding tools or workpieces, they transmit torque and rotation speed, an essential role in precision machining for drilling, milling and grinding. In the automotive and aerospace industries, Suhner Machining spindles are used to produce precise components such as engine blocks and transmission parts, with many metal components running around the clock worldwide, whether for manufacturing engines and gearboxes or machining load-bearing structures.
A range of SPINDLEmaster spindles in ISO and HSK interfaces, with tool changer
TLDR: Suhner Machining's SPINDLEmaster range offers precision machining spindles in ER25/ISO30/HSK50 or ISO40/HSK63 interfaces depending on the power required, with versions fitted with an integrated tool changer (MAX 40 CO model) for automated production.
Suhner Machining's SPINDLEmaster range covers several power and interface levels depending on the application: spindles with motor power from 0.55 to 1.5 kW in ER25/ISO30/HSK50 tool holders, up to spindles of 1.5 to 7.5 kW in ISO40/HSK63 tool holders for applications requiring more torque. The MAX 40 CO model integrates a tool changer directly on the spindle, for the highest demands in concentricity, speed and power, in an automated configuration. The MAX 40 R model, in a version without tool changer, covers the same accuracy requirements for applications where the tooling remains fixed. These spindles equip machine tools and industrial production lines, with a network of Suhner sites in Switzerland (Lupfig), Germany (Bad Säckingen) and the United States.
