1. Technical Positioning of Machine Tool
When processing long shaft parts with traditional single-spindle CNC lathes, secondary clamping and re-alignment after flipping workpieces are mandatory, which easily leads to errors in coaxiality and end face parallelism, and increases labor time, making it unsuitable for mass automated production.
2. Process Improvement vs Ordinary Single-Spindle Lathes
- 60% higher precision: Eliminate secondary clamping positioning and repeated positioning errors, greatly reducing reject rate.
- 40%–70% higher efficiency: Remove two manual processes of flipping and re-alignment, cutting single-piece processing time in half.
- Lower labor cost: One operator can manage 3–5 machines at the same time, suitable for assembly line bulk orders.
- Higher process integration: Drilling, milling and tapping on both ends are completed synchronously without secondary circulation of workpieces in the workshop.
This machine is designed for mass production of rotary long shafts, main processing products include:
Motor output shafts, gearbox drive shafts, hydraulic piston rods, automobile half shafts, fastener pin shafts, agricultural machinery shafts, miniature shafts for precision instruments, water heating valve stems.
Processable materials: 45# carbon steel, 304/316 stainless steel, aluminum alloy, brass, ductile iron and other metal raw materials.
4. Optional Upgraded Technical Accessories
We provide customized upgraded functional components according to customers’ processing requirements:
- Power turret: Support indexing milling and multi-edge forming;
- Workpiece measuring probe: Automatically detect dimensions after processing and compensate parameters for out-of-tolerance parts;
- Automatic bar feeder: Realize unattended processing of long bars;
- Chain / spiral chip conveyor: Automatically clean metal chips to keep the worktable clean;
- High-pressure cooling circulation system: Suitable for heavy cutting of high-hardness steel and prolong tool service life.
If you have demands for mass processing of shaft parts, you can send us workpiece drawings, processing materials and daily output requirements. Our professional engineers will customize exclusive processing solutions and accurate quotations for the double-head lathe. Welcome to contact us via WhatsApp for all technical details.
Our CNC double-head lathe adopts an integrated bed with dual independent servo spindles on the left and right. After one-time clamping of the workpiece, both spindles feed and cut synchronously, completing composite processes including outer circle, end face, inner hole, thread and chamfer in one setup. It is a high-precision CNC machine specially used for mass production of rotary shaft parts.
