Frequently Asked Questions
▸ What is a vertical milling head used for in engine reconditioning?
The vertical milling head is used for precise milling of automotive cylinder heads, allowing surface machining with high accuracy. The CFV-20 offers variable rotation from 80 to 2000 rpm and ±45° inclination, ideal for jobs requiring different cutting angles. With 20 hp motor and ISO 50 taper, it serves industrial shops needing robust capacity for milling various engine cylinder heads.
▸ What are the RPM and power specs of the CFV-20 milling head?
The CFV-20 has variable rotation from 80 to 2000 rpm controlled via frequency inverter, with 20 hp electric motor. Maximum spindle stroke is 2.36 inches (60 mm) and accepts ISO 50 taper. Transmission works via synchronized belts and hardened steel gears with automatic lubrication. Complete dimensions: 19.3 x 12.4 x 42.1 inches (490 x 315 x 1070 mm). Standard voltage 220V three-phase 60Hz.
▸ What type of tooling does this vertical milling machine accept?
The CFV-20 milling machine accepts tools with ISO 50 taper, international standard used in heavy machining. Includes pneumatic quick tool change system as optional. The adaptable sub-head is also optional, offering 50% of original rotations for specific jobs. The prismatic base and spindle nut for crossbeam adaptation comes included, facilitating installation on different machines.
▸ What's the difference between manual milling head and frequency inverter type?
The frequency inverter milling head, like the CFV-20, allows precise and continuous rotation control between 80-2000 rpm, while manual depends only on gear changes. The inverter offers greater versatility for different materials and tools, better surface finish and less vibration. Electronic variation is faster than manually changing gears, increasing shop productivity.
▸ How does cylinder head milling work with lateral inclination?
Milling with lateral inclination allows machining angular cylinder head surfaces without repositioning the part. The CFV-20 tilts ±45° manually to each side, enabling work on valve seats, combustion chambers and non-parallel surfaces. Inclination combined with maximum 2000 rpm ensures efficient cutting at different angles, essential for complex repairs of modern cylinder heads with varied geometry.
▸ What maintenance does the CFV-20 milling head require?
The CFV-20 has automatic lubrication via included pump, reducing maintenance of hardened steel gears. Regular checking of pump oil level, synchronized belt cleaning and ISO 50 taper inspection is necessary. Ground gear transmission ensures greater durability. Preventive maintenance includes checking frequency inverter electrical connections and tool spindle alignment.
▸ Vertical Milling Head CFV-20: how much does it cost?
The CFV-20 is quoted on demand, and pricing varies with each customer's needs, including accessories, tooling and optional features.
