Your custom CNC collet chuck is machined to your exact drawing, not a stock approximation. We verify every critical dimension before shipment. No surprises.
At a glance: ±0.005 mm tolerance on OD/ID, 15-day standard lead time, no MOQ, full material traceability.
Specifications
We run a dedicated CNC turning line for collet chucks and hydraulic chucks. All parts are machined in-house, not outsourced.
Parameter
Value
Material
20CrMnTi, 40Cr, 42CrMo, 65Mn, or your specified alloy
CNC turning, internal grinding, wire EDM for slots
Inspection
100% dimension check, CMM report per batch
Batch size
1 piece to 10,000 pieces
Lead time
15 days for prototypes, 25 days for production
Coating
Black oxide, phosphate, or hard chrome (optional)
We hold 0.005 mm TIR between the collet taper and the pull-back seat. That is not a marketing number. It is a repeatable process capability from our Okuma and Mazak turning centers.
Three reasons buyers send us their drawings
1. Batch-traceable quality. Every heat number, every batch, every operator stamp is logged. If you need to trace a part back to its raw material lot, we can do it in minutes. No guessing.
2. Inspection report per batch. You get a CMM report, hardness certificate, and surface roughness readings with every shipment. Not a generic compliance sheet. Real numbers from real measurements.
3. One factory for CNC + stamping + springs + heatsinks. Your chuck assembly may need a spring collet, a stamped retainer, or a heatsink for the hydraulic actuator. We make all of them under one roof. Fewer vendors, fewer tolerance stack-ups, faster root-cause analysis.
Where these parts are used
Custom CNC collet chucks from our shop run in:
Swiss-type lathes and sliding-headstock machines for medical implant screws
Hydraulic power chucks on CNC turning centers for automotive axle shafts
High-speed pick-off collets for bar feeders in aerospace fastener production
Custom fixture collets for thin-wall tube machining in oilfield tools
Replacement chucks for worn-out OEM units on older Japanese and German lathes
In every case, the buyer needs a chuck that holds concentricity under high spindle speeds and repeated clamping cycles. That is what we build.
Q: Do you have a MOQ?
A: No. We machine one piece for prototype validation. Production pricing kicks in at 50 pieces, but you can order 5 pieces at a fair unit price.
Q: What tolerance can you hold on a collet chuck bore?
A: ±0.005 mm on the bore diameter, ±0.01 mm on concentricity to the taper. For hydraulic chucks, we also verify the seal groove depth to ±0.02 mm.
Q: What is your lead time for a custom chuck?
A: 15 days for a standard material prototype. 25 days for production runs with heat treatment. Faster if you supply the raw material or accept air freight.
Q: Can you provide material certificates?
A: Yes. We issue EN 10204 3.1 mill certificates for all alloy steels. Heat treatment reports include hardness curves and case depth data.
