従来品と比較して、加工穴深さが約倍増したにも関らず、耐久性、安定性が抜群。従来品は、両側からトンボして加工していたものが片側から加工可能になり、さらに加工条件もアップ出来たため、加工時間を大幅に短縮出来た。

FTO-GDXL has excellent durability and stability in spite of 2 times longer hole than conventional process Thus, a work material, which had to be drilled from both sides with the conventional product, can now be drilled from one side Furthermore, the drilling conditions have been improved, resulting in a significant reduction in drilling time

The amount of flank wear after drilling 48 holes continuously (5.76m cutting length) was small, below 0.1mm Thus, it was able to continue drilling The chips were broken into small pieces and the chip discharge performance was favorable Furthermore, this drill could even be operated at a higher feed rate

( )Similar to ANSI 420Stainless Steel

FTO-GDXL machined stainless steels with high speed, high feed, and step free Its work efficiency is 48times better than conventional gun drill

Also FTO-GDXL made holes with 8m long in total and it could continue operation, though conventional gun drill tool life was 1.5m long FTO-GDXL resolves the major issues of long drilling time and short tool life

0.3mm/rev Although it can drill holes even at a feed

rate of 0.1mm/rev, this is not recommended, because

it negatively affects the chip shape and causes the

cutting resistance to fluctuate considerably

( )

切りくず排出がスムースでない他社ドリルの場合、切削抵抗は切りくずが詰まり始めるところから急激に上昇し、切削抵抗波形の振幅が大きく乱れます。また穴が曲がると、ドリルが内壁に接触し切削抵抗の振幅が大きく乱れます。しかし、FTO -M- GDXLはクーラント圧が弱い場合やMQLでの加工においても全く切りくず詰まりのない安定した加工が可能です。

The drill made by another company is unable to eject chips smoothly, and the cutting resistance increases suddenly when it starts to become clogged with chips This causes a significant amplitude disturbance in the cutting resistance waveform Moreover, if the hole bends, the drill will come in contact with the inner wall, causing a significant amplitude disturbance in cutting resistance However, the F TO - M - GDXL is able to drill holes in a stable manner without ever becoming clogged with chips even when the coolant pressure is low or working with MQL (minimal quantity lubrication)

送り量 0.1mm /rev 以下では、切りくずが長くつながる、蛇腹状になるなど切りくず形状が悪くなります。深穴加工において切りくず形状の悪化は切りくず詰まりを引き起こし、ドリル折損に至る可能性があるので、最適な切りくず形状が出る領域での加工を推奨します。

A feed rate below 0.1mm/rev will negatively affect the chip shape, creating chips that are long or form

a bellowed shape While drilling a deep hole, improperly shaped chips will cause the drill to become clogged with chips, which could cause the drill to break Therefore, we recommend that you use the drills

in a range that creates optimal chip shapes

2 Suitable cutting fluid is water-emulsifiable high density oil (less than 20 times dilution).

3 When using water soluble fluid with over 20 times dilution, reduce drilling speed by 30% below the standard conditions Do not use the high speed drilling conditions in this case.

4 When using non-water soluble oil, the lower cutting speed in the table should

be selected Do not use the high speed drilling conditions in this case.

5 These conditions are for drilling depth less than 3 times.

6 When inserting a drill into the machine, use a collet that does not have any scratches or dust located within internal bore Also, reduce deflection of drill to less than 0.01mm.

7 Fasten the work material to reduce the possibility of work deformation, deflection of machined surface, or vibration.

8 A clogged oil hole can lead to a breakage Make sure that a filter is attached

to the oil feeder.
