2031954331 Homag Boring Spindle HUB60 For Weeke CNC Woodworking Machine Parts

Need the boring spindle, not the whole drilling head? Part 2-031-95-4331 / 2031954331 is a Homag boring spindle HUB60 with a 60 mm hub, a 28 mm diameter and a 278.5 mm length, listed as a spare for Homag Weeke CNC woodworking machines. Three numbers decide fit: 60, 28 and 278.5. Caliper the old spindle, match all three, and the repair stays a one-part job. Material is metal, and the price is quoted per enquiry.

A boring head that starts drilling off-centre or oval holes usually traces back to one worn spindle, not a failed unit. Three things then land on the shop floor at once: the machine idles while the fault is chased from gearbox to tooling, the head gets quoted as a complete assembly instead of the single part that failed, and the replacement arrives a size out because nobody calipered the old hub first.

The 2-031-95-4331 Homag boring spindle HUB60 is built for that sequence. It is a metal boring spindle listed as a spare for Homag Weeke CNC machines, with a 60 mm hub, a 28 mm diameter and a 278.5 mm length. Those three are the entire selection check: 60 mm seats the hub in the boring head, 28 mm is the shaft the tooling runs on, and 278.5 mm sets how far it reaches into the head.

One part, two part numbers: 2-031-95-4331 in grouped Homag form and 2031954331 in ten-digit form. Both turn up in catalogues and on quotes, so either one identifies the spindle. Material is listed as metal, and the application line names Homag Weeke CNC machines — the family to check against the plate on your unit before ordering.

No price is published; each order is quoted against quantity and destination. The same line also carries parts for edgebanders, table saws and moulders.

Every line below comes from the part sheet — no estimated values:

• 60 mm hub — the locating diameter that seats the spindle in the boring head. Caliper the old hub across 60 mm; a photograph cannot show you half a millimetre.
• 28 mm diameter — the second fit dimension, the shaft the tooling runs on. Both 60 and 28 have to match before the part will seat.
• 278.5 mm length — the third number. Length sets where the spindle ends against the head, so a part 3 mm short is not a substitute.
• Two part numbers, one spindle — 2-031-95-4331 grouped, 2031954331 ten-digit. Catalogues and quotes use both formats.
• Metal body — the sheet lists the material as metal, so the wear faces at 60 mm and 28 mm are metal rather than a pressed-in sleeve.
• Homag Weeke CNC application — listed as a spare for Homag Weeke CNC woodworking machines, the family that runs HUB60 boring heads.
• Filed as drilling machine parts — it sits in the drilling-machine-parts category, next to the drill spindles and tooling that share the same head.
• Part of a wider spare line — edgebanders, table saws and moulders are supplied from the same catalogue, so one enquiry covers a mixed floor.
• Quote per order — no list price is published; the figure follows quantity and destination.

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

• One part, not one head. The whole specification is three numbers — 60 mm, 28 mm, 278.5 mm — so the spindle is replaced and the boring head you already own stays on the machine.
• Wrong-size returns get caught at the bench. Caliper the old part first: 60, 28 and 278.5 either match or they do not, and that check takes five minutes.
• Two search strings for one part. 2-031-95-4331 and 2031954331 both find it, which matters when a quote arrives grouped and your purchasing file stores ten digits.
• Downtime measured in fitting, not sourcing. A spindle is a single-part swap once the right one is on the shelf, so the head is released the day the part lands.
• One supplier across the floor. Edgebanders, table saws and moulders draw on the same spare-parts line, so a mixed shop does not need four separate accounts.
• Pricing that matches the batch. With no published figure, a ten-piece order and a one-piece repair are quoted as different jobs instead of one list price.

Only if your boring head takes a HUB60 spindle with a 28 mm shaft and a 278.5 mm body. The part is listed as a spare for Homag Weeke CNC woodworking machines, and the 60 / 28 / 278.5 triple is what decides fit, so caliper the old part rather than trusting the machine name on its own.

HUB60 is the hub diameter: 60 mm across the face that locates in the boring head. It is the first of the three selection numbers, together with the 28 mm diameter and the 278.5 mm length.

Yes — one spindle, two number formats. 2-031-95-4331 is the grouped form and 2031954331 is the ten-digit form, so a quote printed either way points at this part.

Metal. The part sheet lists the material as metal and names no other material for the hub or the shaft.

278.5 mm overall. Length sets how far the spindle reaches into the boring head, so a part a few millimetres short will not seat at the same depth — which is why the sheet states 278.5 mm to one decimal.

Price is by enquiry — no figure is published. Send part number 2-031-95-4331 or 2031954331 with the quantity and destination, and the quote comes back against those three.

Yes. The same line covers spare parts for edgebanders, table saws and moulders, so a mixed shop can price several parts in one enquiry instead of opening separate orders.

No — it is listed as a boring spindle only, a single part with the 60 mm hub, 28 mm diameter and 278.5 mm length. Tooling, drill bits and the boring head itself are separate items.
