Chamfer Modules

Chamfer Modules

Chamfer modules are modular cutting tool components for CNC machining centres and lathes that produce chamfered edges on machined parts — removing the sharp corner at a bore or external diameter and replacing it with a controlled angled surface. Chamfering deburrs the edge, eases assembly of mating components, and is often a specified geometric requirement on precision parts. AIMS Industrial supplies chamfer modules for production machining and toolroom applications across Australia.

Modular Tooling Systems

Chamfer modules are designed as part of a modular tooling system rather than as fixed, dedicated tools. In a modular system, a standard tool body or holder accepts interchangeable cutting modules — a chamfer module, a drill module, a reamer module — allowing one holder to serve multiple operations by swapping the module rather than the entire tool assembly. This reduces tool inventory, simplifies presetting, and speeds changeover on multi-operation workpieces.

SECO's Crownloc modular exchange system is a well-known example of this approach — the Crownloc drill body accepts chamfer and other modules at the exchange connection point, converting the holder between operations with a simple, precise exchange. AIMS supplies chamfer modules compatible with the common modular tool systems used in Australian machining operations.

Chamfer Angles

Chamfer modules are available in the standard engineering chamfer angles:

• 45°: The most common chamfer angle for general engineering, deburring, and assembly lead-in.
• 30°: Used where a shallower chamfer profile is needed — less material removal, longer chamfer land on the same depth.
• 60°: Steeper chamfer profile. Used on specific component designs and for certain countersink applications.

Indexable Insert Construction

Most chamfer modules for CNC use are insert-based — a hardened tool body holds one or more indexable inserts that carry the cutting edges. When an insert edge is worn, the insert is indexed to a fresh edge (or replaced) without disturbing the tool body or resetting the tool offset, except for the insert replacement increment. Insert grades are selected based on the workpiece material — coated carbide grades for steel and stainless, uncoated or DLC-coated grades for aluminium.

Selection Criteria

Key parameters when specifying a chamfer module are: the chamfer angle required, the cutting diameter range (the minimum and maximum bore or OD that can be chamfered), the toolholder interface, and the insert grade for the workpiece material. For CNC applications, confirm the module is compatible with the existing toolholder system on the machine before ordering.
