PCD Spiral End Mill

PCD Spiral End Mill for Aluminum, CFRP and Composite Material Machining

PCD Spiral End Mills combine polycrystalline diamond cutting edges with a spiral flute design for efficient and stable milling of aluminum, non-ferrous alloys and abrasive composite materials. Available in different diameters, flute configurations and spiral directions, they can be customized according to the workpiece and machining requirements.

Key Features

---PCD cutting edges for high wear resistance

---Spiral flute design for efficient cutting and chip evacuation

---Suitable for aluminum and composite material machining

---Available in RH and LH spiral configurations

---Different diameters, flute numbers and cutting lengths

Custom tooling available according to workpiece and machining requirements

Spiral Flute Design

The spiral flute is the key geometry of this PCD end mill.

A spiral cutting edge allows the cutting engagement to develop progressively along the tool rather than engaging the entire cutting edge at the same time. The geometry is also designed to support chip evacuation and stable milling.

PCD spiral end mills are offered in both right-hand (RH) and left-hand (LH) configurations. Telcon, for example, specifies RH spiral configurations for aluminum and LH spiral configurations for CFRP in its PCD spiral end-mill range.

The appropriate spiral direction should be selected according to the workpiece material, spindle rotation, cutting direction and machine setup.

Machining Applications

PCD Spiral End Mills are designed for machining aluminum alloys, copper alloys, CFRP, GFRP, MMC and other non-ferrous or abrasive composite materials.

Typical milling operations include:

• Profile milling

• Side milling

• Shoulder milling

• Slotting

• Edge trimming

• Contour machining

• Roughing and finishing

For composite materials, PCD spiral end mills are used particularly for trimming, edging and material removal operations. Telcon specifically describes its PCD spiral end mills for high stock removal in CFRP and aluminum applications.

For aluminum components, PCD spiral milling tools can be used for profile and precision machining where tool wear and surface quality are important considerations.

PCD Spiral End Mill Configurations

Different tool configurations can be selected according to the machining application.

Right-Hand Spiral

RH spiral PCD end mills are available for aluminum machining and other applications requiring a right-hand cutting configuration.

Left-Hand Spiral

LH spiral PCD end mills are available for composite machining applications such as CFRP.

Flute Configuration

The number of flutes can be selected according to the tool diameter and machining requirements. Published PCD spiral end-mill ranges include 3-flute and 4-flute configurations.

Chip Breaker

A chip-breaker configuration can also be incorporated into certain PCD spiral end mills. Telcon describes chip breakers as an option intended to reduce cutting load and vibration in its spiral PCD end-mill range. 

PCD Spiral End Mills are available in different dimensions depending on the manufacturer and tool series. For example, Telcon's published RH series includes 6, 10, 12 and 16 mm cutting diameters, with corresponding shank diameters, cutting lengths, overall lengths and flute numbers.
