1. Product Overview & Core Processing Functions
Traditional shaft machining relies on separate lathes, milling machines, drill presses and tapping machines. Workpieces need multiple clamping, handling and repositioning between each process, which brings three major drawbacks: long cycle time, accumulated positioning errors and high labor costs.
Our 4-in-1 composite CNC special machine perfectly solves this pain point. With one single clamping of raw material, the equipment automatically finishes all required machining steps sequentially:
- Face Milling: High-speed surface milling to guarantee flatness and perpendicularity of workpiece end faces
- U-Drilling: Indexable U drill deep hole machining, efficient chip removal, smooth hole inner surface
- Precision Tapping: Synchronous tapping with stable spindle feed control, standard internal thread without burrs
- OD External Turning: Finish turning outer circle to achieve tight dimensional tolerance and good circular runout
-
All processes are driven by one unified CNC program, no manual adjustment needed during full production. 2. Core Technical Advantages 2.1 Ultra-High Machining Precision One-clamping processing avoids datum shifting caused by repeated disassembly. Coaxiality, flatness and thread tolerance can be stably controlled within ±0.01mm, reject rate reduced by over 40% compared with discrete equipment production lines. 2.2 Remarkable Production Efficiency Improvement Cancel intermediate material transfer, clamping and calibration procedures. The total machining cycle time of one workpiece can be shortened by 30%–50% for mass production. One operator can manage multiple units simultaneously, cutting labor expenditure significantly. 2.3 High Rigidity & Stable Machine Structure Heavy cast iron machine base with stress relief annealing treatment, anti-vibration design during high-speed cutting. All linear guides and ball screws adopt top-grade brands, long service life and low maintenance frequency. Every machine undergoes 72-hour full-load running test before shipment to eliminate latent deformation problems. 2.4 Full Customization Support We tailor every machine according to customer workpiece drawings: Adjustable X/Y/Z axis travel range to fit different part lengths & diameters Optional servo spindle speed, power and cooling system (air cooling / water cooling) Custom dedicated fixtures, automatic feeding & unloading modules Compatible mainstream CNC systems: Siemens, FANUC, Mitsubishi, domestic cost-effective control systems 2.5 Wide Material Compatibility Suitable for machining carbon steel, alloy steel, stainless steel, aluminum alloy, brass and other common metal blanks; matched with corresponding carbide inserts and U drill tools to guarantee long tool life. 3. Machine Standard Configuration CNC System: Optional FANUC / Siemens / Mitsubishi intelligent control panel, USB & Ethernet program input Drive System: Full servo motors and drives for all moving axes, closed-loop position feedback Cutting Spindles: High-speed rigid spindles for milling, drilling & tapping; independent turning spindle for OD processing Guide & Transmission Parts: Precision linear guides, high-precision ball screws with automatic lubrication system Cooling & Chip Removal: Built-in cutting fluid circulation system, optional spiral chip conveyor for long-time unmanned operation Safety Protection: Fully enclosed transparent safety shield, emergency stop button, overload automatic alarm function 4.
