Plastic CNC Tool Holders Forks HSK63F Holder Clips For Tool Changer Replacement

A tool changer that drops a holder mid-cycle is usually a worn plastic fork, not the arm. Part 1705A0123 is the white HSK63F tool holder fork that carries the holder in the carousel and releases it to the spindle: 8–10 kg load, G2.5 at 30,000 r/min, 0.005 mm yaw precision, tested past 60,000 tool change cycles, and up to 95% the shape of the Italian fork it replaces. In stock, ships in 1–7 working days, sample available.

A tool changer that drops a holder usually comes back to three things: a plastic fork whose jaw has worn oval, a replacement that lands weeks after the machine stopped, and a clip that looks identical but returns at a different centre height. With a change every few minutes, any of the three ends the same way: an idle spindle, a scrapped panel, a fixture to re-datum.

Part 1705A0123 is the white plastic HSK63F tool holder fork for that position. It is the gripper that carries an HSK63F holder in the carousel and hands it to the spindle. The plastic shell is reinforced around a cast alloy steel block and located by steel positioning pins, so the jaw keeps its form when the changer closes under load.

Rated loading capacity is 8–10 kg, balance grade G2.5 at 30,000 r/min, yaw precision 0.005 mm, and the fork is tested past 60,000 tool change cycles. It is moulded from the same plastic compound as the Italian forks it replaces and holds its clutch tolerance through workshop temperature swings.

Delivery runs 1–7 working days from stock, and a sample is available before you commit. The same fork is listed for Biesse, KDT, Nanxing, Excitech, Emmegi Comet T6, Multicam, Thermwood, CR Onsrud, Laguna, Techno, Northwood, DMS, Flexicam, COSMEC, Bulleri, KUKA, FANUC and YASKAWA changers.

What separates this fork from a plain plastic clip is how the steel core and pins are built in.

• Cast alloy steel core — the plastic shell is reinforced around a cast steel block, so the jaw takes 8–10 kg without spreading.
• Steel positioning pins — steel pins locate the fork in the changer, so it returns to the same axis instead of being set by eye.
• G2.5 balance at 30,000 r/min — the fork is balanced to G2.5, which keeps its own vibration out of the taper at HSK63F spindle speed.
• 0.005 mm yaw precision — grip position repeats inside 0.005 mm, so the changer picks the same point on every holder in the magazine.
• Temperature tolerance — the compound resists workshop temperature change and holds clutch tolerance, so grip does not drift from a cold morning to a hot afternoon.
• Tested past 60,000 changes — the fork has run over 60,000 tool change cycles on test, the number a busy carousel asks for.
• Up to 95% form match — the outline is up to 95% the same as the Italian fork it replaces, with service life over 90%.
• One number, many brands — the same 1705A0123 fork is listed for Biesse, KDT, Nanxing, Excitech, Multicam, Thermwood, Laguna, Techno and the other changers named above.

When a fork fails, the real choice is between waiting on an import and fitting a clip that will not repeat its centre height.

• A tool change is not the place to save money. A fork that costs a fraction of a holder still decides whether an 8–10 kg holder lands in the taper or on the table.
• Stock, not a six-week wait. Delivery is 1–7 working days, so the magazine is back in production in the same week the fault is found.
• Same balance grade as the spindle. G2.5 at 30,000 r/min means the fork adds no vibration to the holder and spindle bearings behind it.
• Repeatable pick point. 0.005 mm yaw precision keeps the changer gripping the same spot on every HSK63F holder, so tool length offsets stay valid.
• Tested, not estimated. 60,000 change cycles on test means the jaw has already done the cycles a busy router will ask of it.
• A sample before a box. One fork can be fitted and run on the machine before a batch is ordered, and a sample is available for exactly that.
• One part covers a mixed plant. The same 1705A0123 fits Biesse, KDT, Nanxing, Excitech and the other changers listed, so one stock line covers several machines.

Yes, if your changer takes an HSK63F holder and the fork you are removing carries 1705A0123. The part is listed for Biesse, KDT, Nanxing, Excitech, Emmegi Comet T6, Multicam, Thermwood, CR Onsrud, Laguna, Techno, Northwood, DMS, Flexicam, COSMEC, Bulleri, KUKA, FANUC and YASKAWA. Match the number on the old fork first; the machine brand alone is not enough.

Yes, because the plastic is only the shell. A cast alloy steel block sits inside the reinforced body and steel positioning pins carry the location, which is how the fork reaches a 8–10 kg load rating instead of relying on plastic alone.

More than 60,000. That is the tested figure for this fork, and it is stated as service life above 90% of the Italian part it replaces.

Up to 95% on shape, using the same plastic compound, with service life over 90%. It is a replacement for that fork, not a lookalike with a different fit.

Because that is the figure keeping the holder square in the gripper. Once the jaw wears past it, the changer still picks the tool, but the taper sits slightly off, and the error shows up as runout at the cutter.

No. The fork is the replacement item — it goes onto the existing changer arm and holds the existing HSK63F holders, so nothing behind it has to be changed.

Yes. The compound is specified to resist temperature change and to hold clutch tolerance, which is why grip stays consistent between a cold start and a warm afternoon.

1–7 working days from stock, and a sample is available. Order one fork, fit it, run a shift, then size the batch from what the magazine actually needs.
