The old zero-rake cutoff tool generated such high cutting forces that it distorted the workpiece.
The cutoff tool he was using kept the sleeve geometry barely within squareness tolerance and with a barely acceptable "glazed" finish.
The new model 42-9LSS 4-axis CNC 1 5/8" bar machining with sub-spindle that utilizes three-sided tool platen featuring 9 live tools (3 on each side), 6 stationary drill holders, 8 turning holders plus a separate cutoff tool
holder for complete parts production at one location.
The cycle starts with the cutoff tool
in its furthest advanced position: directly in front of the guide bushing, with the cutting edge just past the center line of the barstock.
Four tools are used to produce it: a grooving tool, cutoff tool
, a 1/4" dog bone, and an insert turning tool.
com spokesman Nathaniel Kelly includes a wide range of domestic and foreign made sawing machines, reamers, endmills, high-feed milling cutters, abrasives, diamond drills, cutoff tools
, stainless steel arbor shims, precision microdrills, superabrasives, Blanchard grinders, centerless grinding machines, high speed steel-fin cutters, reamers, stainless steel taps, threading systems, gear cutters, boring bars, grooving equipment, inserts, carbide end mill tools, laser systems and other types of tools for cutting all kinds of metals, plastic, wood, glass, rubber, brick, iron, concrete and other materials.
Then, in the latter half of the 1970s, Iscar focused intently on one niche within cutting tools--applications for cutoff tools
As with tooling and inserts for other operations, grooving and cutoff tools
are being developed to allow for the faster speeds and higher feedrates that modern machine tools permit.
The product lines include MTC[TM] integrated insert and toolholder system, Separator[R] cutoff tools
, Chipmaker[R] O.
Included in the standard package are 10 different sizes of OD turning VM 63 tools, four different sizes of grooving and cutoff tools
, nine different end mill adapters, eight different turning adapters, four different ID boring VM63 tools, five different boring bar adapters, three different shell mill adapters, eight different collet chuck adapters, two different tap adapters, two hydraulic chuck adapters, one extension, and three different reducers, and a complete supply of carbide cutting tool inserts.
The new cutoff tools
also include a unique insert stop design that automatically increases clamping forces as cutting forces increase, providing secure holding in even the toughest cuts.
New cutoff tools
are offered with cutting widths varying from 0.
