1. Batch-traceable quality. Each batch gets a unique number. You can trace material heat number, heat treatment record, and inspection data back to the exact production run. If a problem appears in your assembly line, we identify the cause in minutes, not days.
2. Inspection report per batch. You receive a full dimensional report with every shipment. CMM data, hardness readings, surface roughness values. Not a generic certificate. Real numbers from real measurements. Your incoming QC signs off faster.
3. One factory for CNC + stamping + spring + heatsink. Your collet chuck is not the only part in your machine. We also make the springs inside the chuck, the stamped washers, and the heatsink for your spindle motor. One purchase order, one logistics point, one quality standard. Fewer suppliers means fewer headaches.
Where these parts are used
This 42-type collet chuck with square bar stock is designed for automatic lathes and CNC turning centers that feed square or hexagonal bar stock.
Typical applications:
Swiss-type automatic lathes (Citizen, Star, Tsugami) running square brass or aluminum bars for electrical connectors.
Multi-spindle automatics processing square steel stock for hydraulic fittings.
CNC turning centers with bar feeders handling square 42 mm stock for automotive sensor housings.
Precision instrument spindles requiring square bar clamping with zero runout.
The square bore holds the bar firmly without rotation. The slot allows radial compression. The hardened surface resists wear from continuous bar feeding. You get stable machining, fewer rejects, longer tool life.
Q: What is your minimum order quantity?
A: No MOQ. We make one prototype for your validation, then scale to your production volume. Many buyers start with 5 pieces for testing, then order 500 or 5,000.
Q: How do you control tolerance and quality?
A: We use CNC lathes and grinders with in-process gauging. Every critical dimension is measured on a CMM. We send you the inspection report before shipment. If a dimension is out of spec, we rework or scrap it. You never receive a bad part.
Q: What is your lead time?
A: Prototype in 7 days. Production in 15 days after drawing approval. For urgent orders, we can expedite to 5 days for an additional charge. We ship worldwide via DHL, FedEx, or your freight forwarder.
Q: Can you provide material certificates?
A: Yes. We provide mill certificates for raw material, heat treatment reports, and hardness test certificates. All documents are in English and available with your shipment.
