2031954791 Drilling Machine Parts HUB60 Boring Shaft Spindle For Homag Weeke

Need the spindle, not the whole drilling head? Part 2-031-95-4791 / 2031954791 is a steel boring shaft with a 60 mm hub diameter and a 28 mm shaft diameter, listed as the right drilling spindle for Homag boring axes marked HUB=60/D=28 RE KPL on Homag Weeke CNC machining centers. Two numbers decide fit: 60 and 28. Caliper the old part, match those two, and the repair stays a one-part job instead of a head rebuild. Price by enquiry, delivery place Foshan, China.

A drilling unit that starts boring oval or off-position holes usually has one worn part behind it. Then three things hit the shop at once: the machine stands idle while the fault is tracked down, the whole drilling head gets quoted instead of the single spindle that failed, and the replacement arrives the wrong size because nobody measured the hub first.

The 2-031-95-4791 boring shaft is built for exactly that sequence. It is a steel boring spindle for Homag Weeke CNC machining centers, made to the Homag boring axis designation HUB=60/D=28 RE KPL, with a 60 mm hub diameter and a 28 mm shaft diameter. Those two diameters decide fit, and they are the two numbers the part number is built around.

The datasheet lists it as a vertical drilling spindle and names it the Homag right drilling spindle, so it sits at the right-hand position of the boring axis. The same part travels under two numbering styles: 2-031-95-4791 in grouped form and 2031954791 in ten-digit block form, which is why both appear on the datasheet and in quotes.

Material is steel throughout. No price is published — it is quoted per enquiry — and the delivery place is Foshan, China. Before you order, caliper the hub and shaft on the old spindle: 60 mm and 28 mm means you have the right part.

Every line below is taken from the datasheet — nothing here is estimated:

• 60 mm hub diameter — the locating face on the boring axis. Measure 60 mm across the old hub with a caliper, never off a photo.
• 28 mm shaft diameter — the second fit dimension. 60 and 28 together make the HUB=60/D=28 pair, and one millimetre out means it will not seat.
• 2-031-95-4791 / 2031954791 — one spindle, two number formats: grouped for the Homag-style catalogue, ten digits for the search field.
• Steel body — material is listed as steel, so the wear faces are metal at 60 mm and 28 mm rather than a sleeve pressed in later.
• Homag Weeke CNC machining centers — the application line names the machine family, so check the plate on your unit before buying.
• Right-hand spindle — described as the Homag right drilling spindle, so the left and right positions are not interchangeable at 60 mm.
• RE KPL compatibility string — quote the full line HUB=60/D=28 RE KPL when asking for a cross-check; that string is what a supplier matches.
• Quote-only price, Foshan delivery — no figure is listed: pricing is per enquiry and the delivery place is Foshan, China, in the same email.

The alternative to this part is rarely a better spindle: it is an agent visit, or another season on a shaft that bores off-centre.

• One part instead of one head. The whole specification is two diameters, 60 mm and 28 mm, so you replace the spindle and keep the drilling head you already own.
• Wrong-size returns get avoided up front. Caliper the old part first: 60 and 28 either match or they do not, and that check takes five minutes.
• Two search strings for one part. 2-031-95-4791 and 2031954791 both find it, which matters when a quote arrives in grouped form and your ERP stores ten digits.
• Steel shows you where it wears. A steel boring shaft wears at the hub face and the bearing seat — both visible on the old part at 60 mm and 28 mm.
• The position is stated, not assumed. Right drilling spindle for Homag Weeke machining centers, so the left/right question closes before the order goes out.
• Pricing that matches the batch. No list price is published: you state the quantity and get a figure from Foshan, China, for that batch.

Only if your boring axis is marked HUB=60/D=28. It is listed for Homag Weeke CNC machining centers as the right drilling spindle, but the two diameters decide fit: 60 mm hub and 28 mm shaft.

HUB=60 is the hub diameter at 60 mm and D=28 is the shaft diameter at 28 mm. Both are outside diameters on the part you are replacing, so caliper the old spindle instead of scaling a drawing.

Yes — one spindle, two number formats. 2-031-95-4791 is the grouped form and 2031954791 is the ten-digit block form, so a quote printed either way points to this boring shaft.

Steel. The datasheet gives the material as steel and lists no other material for the hub or the shaft.

It is part of the Homag designation HUB=60/D=28 RE KPL, so quote the line in full. When a supplier cross-checks your spindle, that diameter pair plus the suffix is what they match against.

Price is by enquiry — no figure is published. Send part number 2-031-95-4791, the quantity and your destination, and the quote comes back against those three.

Foshan, China. The datasheet states the delivery place as Foshan, and the spindle is quoted per enquiry rather than sold at a published web price.

No — it is listed as the Homag right drilling spindle. The 60 mm / 28 mm pair tells you the size; the right-hand designation tells you the position, and both have to match your boring axis.
