Typical component families for woodworking machine builders — tool holder shafts, feed rollers, pressure plates and cams in steel and stainless — supplied in machine-builder batches with ground finishing where it counts.
| Tool holder shafts | C45, alloy steel, turned + ground |
| Feed rollers / pressure plates | Steel, stainless, turn-milled |
| Cams | Alloy steel, heat-treatable |
| Batch range | 100–5,000 pcs per family |
| Tolerance scheme | DIN ISO 2768-mK, seats ground |
| Documentation | EN 10204 3.1, dimension reports |
Woodworking machine builders concentrate on frames, spindles drives and controls; the turned and milled precision components — tool holder shafts, feed rollers, pressure plates, cams — are bought against drawings in machine-builder batches, typically 100 to 5,000 pieces per part with program-specific variants.
The components see continuous vibration, dust load and static cutting forces, so ground finishing on bearing seats and hardness-appropriate material selection matter as much as dimensional accuracy.
| Component (IT / EN) | Typical material | Process | Typical batch |
|---|---|---|---|
| alberi portautensili (tool holder shafts) | C45, alloy steel | turning + cylindrical grinding | 100–2,000 pcs |
| rulli di traino / piastre (feed rollers, pressure plates) | steel, stainless steel | turn-milling | 500–5,000 pcs |
| camme (cams) | alloy steel | turning + heat treatment | 100–2,000 pcs |
Bearing seats and rotationally symmetric surfaces are ground after heat treatment where the drawing calls for it; runout values are confirmed per shaft family.
The standard flow: drawing review and quotation within 48 hours, first samples in 7–15 days, first article inspection and approval, then series production against the approved reference. Tooling, program revisions and inspection records are kept on file so that call-offs remain consistent with the approved first article.
Engineering changes — material substitutions, tolerance updates, plating or packaging changes — are handled as controlled changes against the same records.
DIN ISO 2768-mK applies as the default tolerance scheme for unspecified dimensions. EN 10204 3.1 inspection certificates are standard for metallic parts, First Article Inspection supports the approval step, and RoHS/REACH declarations are available where required. Plating, cleanliness and packaging requirements are confirmed per drawing.
Which batch sizes fit your process?
Tool holder shafts from 100 pieces; rollers and plates from 500 pieces; both with recurring program supply.
Can you handle ground-finish shafts?
Yes — cylindrical grinding after heat treatment, with runout and diameter values confirmed per drawing.
Which materials are typical in this vertical?
C45 and alloy steels for shafts and cams; stainless for guide and pressure surfaces exposed to moisture and resins.
Which documents accompany the parts?
EN 10204 3.1 certificates and dimension reports; heat-treatment records where applicable.
