Horn solid carbide groove milling cutters get down to ‘SuperMini’ bore diameters
1 min read
Horn considers its System DC solid carbide groove milling range for machining threads, full radii and square corner grooves, and chamfers to be an important addition to its offering. This is particularly so in the case of the smaller diameters among the 140 standard variants which offer capability for multi-tooth interpolative groove milling within bore diameters that have hitherto only been accessible using SuperMini single point tooling.
The cutters are available in a variety of carbide grades and the range is divided into five sub-sets according to function.
System DCG comprises a comprehensive range of thread milling tools developed to produce precise full and partial profile threads in the range M3 to M12. Inch-based UNC/UNF/UNEF threads from #5-40 UNC to 7/16-20 UNF are also covered, as are Whitworth/BSF formats from 1/8-40 BSW to 1/2-16 BSF. Maximum working depth ranges from 8 to 30 mm.
DCR full radius groove milling is covered by a series of tools with three or four teeth. Cutting edge swept diameters from 4 to 10 mm offer capability to machine grooves from 0.5 to 2.0 mm depth. Groove width range is from 1.0 to 3.0 mm and maximum operating depth is from 4.0 up to 20 mm. The 'square edged' DCN range offers fundamentally similar machining dimensions.
The DCX groove milling cutters are larger diameter tools with six or eight teeth and swept diameters of 20, 30 and 40 mm. These offer capability to machine grooves of 6.5, 10 or 13.5 mm depth. Maximum groove width is 2.0 mm.
Lastly, the DCF chamfering tooling produces a standard chamfer/groove angle of 45º. Nine tools cover swept diameters from 2.0 to 7.5 mm and the maximum groove depth is 1.5 mm.
