Deburring centre performs five-axis
finishing
A 5-axis CNC deburring centre carries out automated deburring and light machining of cast or pre-machined metal components, so eliminating tedious and costly hand finishing.
The Japanese machining centre manufacturer, Kira, has introduced a 5-axis CNC model specifically for automated deburring and light machining of cast or pre-machined metal components It is equally capable of removing the flashing from plastic parts that have been injection moulded or vacuum formed

Sole UK agent is Yuasa Warwick Machinery.
Called Deflash, the machine replaces tedious and costly hand finishing and eliminates the variable finish that often results.
Alternatively, it may be employed for drilling, tapping, chamfering, light milling and other machining operations for which 2.2kW of continuous spindle power (3.7kW peak) is appropriate.
The machine reduces the workload on more expensive, higher power machining centres that might otherwise be tied up doing inappropriately light operations if automated deburring has been decided upon.
Moreover if a first-operation machining centre has less than five computer-controlled axes, it might not have sufficient dexterity for efficient in-cycle deburring and may also need special tooling.
To program Deflash, it is simply necessary to clamp the first part on the table and move a touch probe by hand around the features to be deburred or machined.
Using this teach-in method, a sequence of cutter paths is built up in the memory of the Fanuc 21i-MA control.
The size of component that can be accommodated is defined by the X:600mm by Y:400mm by Z:500mm working envelope.
The table tilts around a horizontal centreline through a full 360 degrees (A-axis) whilst rotation of the whole table assembly is +/-180 degrees (B-axis), allowing a considerable degree of versatility when presenting the part to the cutter.
Specification of Deflash includes a turret head containing five BT30 taper tools (optionally seven) that can be exchanged in one second (3.5 seconds chip-to-chip), spindle speed up to 8,000 rpm, 4,000 rpm rigid tapping, 15m/min cutting feed rate in all linear axes with 20m/min rapids, 20 and 25 rpm rapids in A and B respectively, and 10 microns positioning accuracy over 300 mm with 5 microns repeatability.
