Selection criteria for carbide cutters, flute configurations, coatings, and custom soft jaws.
Modular tombstones (column fixtures) provide 4, 6, or 8 precision ground vertical clamping faces on HMC rotary pallets, enabling high-density multi-part batch production and massive spindle uptime gains.
Dovetail workholding utilizes a precision 45° or 60° dovetail prepped at the base of raw stock, providing rigid multi-axis cutting access to 5 full part faces with only 2–3mm of material grab.
ER collets (DIN 6499) are the most universal flexible tool clamping system in CNC manufacturing, featuring an 8° double-angle taper and 1mm collapse range for drills, taps, reamers, and end mills.
HSK (1:10 hollow taper) and BT/BBT (7:24 steep taper) spindle interfaces govern toolholder clamping force, dynamic radial stiffness, and centrifugal expansion behavior in modern CNC milling machines.
Bull nose (corner radius) end mills combine flat bottom cutting capability with reinforced corner radii (R0.5 to R4.0mm), preventing sharp-edge chipping and outperforming square end mills in high-load pocketing.
Vacuum chucks utilize atmospheric air pressure differential to clamp thin aluminum plates, sheet metal, and plastic panels uniformly across their entire bottom surface with zero edge clamp interference.
Indexable face mills are large-diameter cutters with replaceable carbide inserts designed for high metal removal rates (MRR) and achieving mirror-flat datum reference planes on raw stock.
High-precision toolholding systems (Shrink-fit and Hydraulic chucks) eliminate collet play, guaranteeing total indicator runout (TIR) under 3 microns for high-speed micro-milling and deep cavity moldmaking.
Zero-point clamping systems utilize precision ground pneumatic or hydraulic pull-stud receivers mounted to machine tables, achieving sub-0.005mm repeatable fixture positioning in seconds.
