Chamfering Tools
What is...
Wixroyd Chamfering Tools, which are mainly used on drills, create high quality consistent inner or outer chamfers between 60° to 120° inclusive angle on a wide range of metals.
Features
- Concentric chamfers.
- Excellent surface finish.
- Reduces risk of cutting into the workpiece.
- Controlled machining torque.
Chamfering Tools consist of three main elements; attachment spindle, pilot cone and cutting blade.
A variety of spindle attachments are available from CM1, CM2 and CM3.
General Guidance
When the chamfer tool's spindle is lowered, its pilot cone firstly centres the workpiece, then retracts to allow the blade to come into contact with the material and start cutting of the chamfer.
Adjusting the output of the blade controls the thickness of the chip count, NOT the value or angle of the chamfer e.g. with a blade output of 0,4mm the Chamfering Tool requires 10 revolutions to cut 1mm of the chamfer.
Concentric chamfer achieved.
Technical Specs
Recommended cutting speed
Typical rpm for varying chamfer diameters, when using cutting speed of between 10 and 20 m/min.
We recommend a cutting speed of between 10 and 20m/min. Hence typical value for chamfers of varying diameter are as follows.
| Diameter | RPM range |
| 10Ø mm | 320 to 640 rpm |
| 15Ø mm | 210 to 420 rpm |
| 20Ø mm | 160 to 320 rpm |
| 30Ø mm | 110 to 220 rpm |
| 40Ø mm | 80 to 160 rpm |
| 50Ø mm | 55 to 110 rpm |
We do however recommend you use the following formula to check the most suitable rpm used.
Rpm = (cutting speed x 1000) / (diameter x 3.14)
| Blade cutting angle | 0° | 14° | 20° | 25° |
| Suitable for material | Brass, bronze, cast iron, stainless steel | Steel, special bronze, perspex | Soft steel, copper, AU 4G, plastic, stainless steel | Aluminium, soft iron, sheet metal |
Important Note: We recommend Chamfering Tool is lubricated with cutting fluid or soluble oil to ensure long life of cutting blade edge and to reduce wear of the pilot cone.
We offer blades with a variety of cutting angles to best suit the material in which a chamfer is required.
Typically a bald cutting angle of 14° suits most applications, please refer to table above.
