Milling Heads
The milling heads in this line cover standard vertical milling through angular operations with 360° positioning. The range includes heads with 4, 8 and 12 speed steps powered by 5.0 or 8.0 hp motors, plus the CFV-20 vertical model with variable-frequency drive (80–2,000 rpm) and 20.0 hp. For perpendicular or angular cuts, sub-heads mount directly onto the main head's spindle and reduce output speed by 50%, operating with ISO 30 or ISO 40 tapers. All models transmit rotation through hardened and ground steel gear sets with automatic pump lubrication. Lateral tilting of up to ±45° is available on the main models. Check the individual spec sheet for each model to confirm the exact dimensions and capacities that match your application.
Specifications subject to change without notice. Some capacities listed may require optional accessories depending on the model. Refer to each unit's technical datasheet for exact dimensions and limitations.
Frequently asked questions
What is a milling head and what is it used for?
A milling head is the assembly that mounts onto the ram or overarm of a milling machine and holds the spindle and toolholder. It transmits rotation to the cutter, enabling flat, angular and perpendicular milling operations on metal workpieces. Without it, the base machine cannot perform cutting operations. The models in this line are designed for universal and bed-type milling machines of various sizes.
What is the difference between a vertical milling head and an angular sub-head?
A vertical milling head (such as the CFV-20 or the R-4, R-8 and R-12 models) is the main unit mounted on the ram — it delivers power and speed to the cutting tool. An angular sub-head (CF-1, CF-2 or CF3-CNC) is an accessory that attaches to the main head's spindle and redirects the cut to a different angle, such as 90°. The sub-head always runs at 50% of the speed of the head it is coupled to.
What speed ranges and power ratings are available in this line?
Models vary significantly: the R-4 provides 4 speed steps (108 to 1,260 rpm) with a 5.0 hp motor; the R-8 has 8 speeds with 5.0 or 8.0 hp motors; the R-12 offers 12 speeds with different rpm ranges depending on the motor chosen. The CFV-20 operates with variable-frequency control from 80 to 2,000 rpm at 20.0 hp. Check the individual spec sheet for each model to confirm the exact speed range required for your operation.
Will these milling heads fit my existing milling machine?
Compatibility depends on the spindle taper (ISO 30, ISO 40 or ISO 50) and the dimensions of your machine's ram or overarm. Most models include a prismatic base and leadscrew nut for mounting. When replacing a head on an existing machine, a drawing or sketch of the ram cross-section must be provided by the buyer. The lateral traversing leadscrew for the ram is an optional item on most models. Consult the spec sheet of each model to verify compatibility with your setup.
How do I request a quote or technical support for milling heads?
Contact the Chinelatto technical team with details about your milling machine model, the current spindle taper (ISO 30, 40 or 50) and the operation you need to perform. For retrofits on existing machines, have the ram drawing ready. The team will advise on compatibility, optional items and spare parts availability. Use the contact form on the website or reach out directly through the commercial channel to receive your quote.
