Machined Transmission Parts
CNC-turned and milled non-standard transmission components, from your DWG or STEP file.
When a transmission assembly needs a non-catalog part — a custom flange, an idler axle, a clamping collar, a motor adapter, a non-standard hub — Wolfer's machine shop handles it. CNC turning, milling, 4-axis machining, and full heat / surface treatment, all under one roof.

What we make
Machined Parts we cut from drawings.
Adapter flanges
Motor-to-gearbox, gearbox-to-machine, custom bolt circles
Clamping collars / hubs
Split clamp, double-bolt, custom-bore
Idler shafts / axles
Stepped shafts for pulley and sprocket idlers
Bearing housings
Custom housings for non-standard bearing sizes
Motor-extension shafts
Custom motor outputs for non-standard motor flanges
Locking nuts & rings
Locknuts, retaining rings, spacers — to drawing
Half of every gearbox is the gears; the other half is the assembly hardware — adapter flanges, motor-mount plates, bearing covers, clamping collars, idler shafts. We make those from your DWG / STEP / PDF, with the same heat-treatment and inspection programs that our gears go through.
Common requests: motor-extension shafts cut to fit a non-standard motor flange; idler-pulley axles with custom keyways; clamping collars for shaft positioning; one-off bearing housings for prototype assemblies; replacement flanges for legacy equipment where the original supplier is gone.
Order sizes run from a single replacement piece to batches of 200–500. For higher volumes we partner with our extended supply chain for casting + machining, with Wolfer holding the inspection responsibility.
Standards
Built to international tolerance specs.
- ISO 2768-mK (general tolerance)

- ASME Y14.5 (GD&T)
Inspection
Every part measured before it ships.
- CMM — for ± 0.005 mm features
- Optical projector — profile / radius / chamfer verification
- Air gauges for bore tolerances
- Surface roughness tester

FAQ
Common questions from engineers buying this product.
Do you accept STEP files only, or do you need 2D drawings?
Either. A STEP file plus a 2D drawing showing critical dimensions and tolerances is ideal — the STEP gives us the geometry, the 2D tells us where to hold tight tolerance and what surface finish to target.
What is the minimum order quantity?
One piece. We routinely cut replacement parts for OEMs where the original supplier has closed or discontinued the part.
