High frequency spindles – high-performance spindles for HSC and HPC machining
– High performance for HSC/HPC machining
High-frequency spindles belong to the category of motor spindles, meaning that the motor is not external but integrated directly into the spindle body. They are a central element of modern CNC machines and play a decisive role in determining efficiency and precision during milling, grinding, drilling or deburring. HS Drive TeC is your experienced partner for high-frequency spindles and offers not only an extensive product portfolio but also individual services: from technical consulting and spindle selection to maintenance and repair.
HS Drive TeC offers you a wide range of High-Frequency Spindles for HSC/HPC Machining
What is a high-frequency spindle and how does it work?
A high-frequency spindle (often referred to as an HF spindle) is a rotating drive used in machines such as CNC milling machines, grinding machines or drilling systems to drive tools at extremely high speeds – usually in the range of 10,000 to over 100,000 revolutions per minute (rpm).
It is a compact, integrated electric motor that drives the tool interface directly and is specifically designed to achieve very high speeds on a continuous basis.
How high-frequency spindles work
1. Drive
An electric high-frequency motor inside the spindle generates the rotational motion. Most HF spindles are asynchronous and require a frequency inverter to set the desired speed precisely.
2. Tool interface
The tool (e.g. milling cutter, drill, grinding wheel) is clamped directly in the spindle using a collet or another clamping system.
3. Speed control
The frequency inverter enables stepless speed adjustment. The optimum speed is set based on the material and application.
4. Bearing system
A high-frequency spindle contains high-precision ball bearings or ceramic bearings capable of handling extreme speeds and forces – often using grease or air-oil lubrication.
Product overview: High-frequency spindles & accessories
As a distribution partner of renowned manufacturers, we offer a wide range of HF spindles, clamping systems and accessories – all tailored to industrial requirements.
HF motor spindles – for maximum speed and process reliability
Our HF motor spindles are designed for a wide variety of applications. Key technical data:
Our Standards:
| Power | 0.1–5.0 kW |
| Speed | 30,000–90,000 U/min |
| Tool holder solutions | ER 8, ER 11, ER 16 |
| Motor type | asynchronous built-in motors |
| Cooling | fan-cooled, compressed-air-cooled, liquid-cooled |
Special variants:
- centric high-frequency spindles
- HF spindles with collet interface
- liquid-cooled high-speed spindles
- frequency inverters for precise control
All spindles are engineered for maximum runout accuracy and can be easily integrated into existing CNC milling machines. They are suitable for both common machining methods – High Speed Cutting (HSC) with very high speeds and High Performance Cutting (HPC), where large chip volumes are required.
Accessories & extensions for your high-frequency spindle
The right accessories increase the flexibility of your machining processes:
- collets and reduction sleeves
- compressed-air and liquid cooling units
- adapters, connection kits, sensors
- torque couplings and changeover devices
