8 Spindle CNC Brass Faucet Peeling Machine – DK850-8

Description

一、Machine Description

The DK850-8 eight-spindle peeling machine is an 8-head synchronous CNC peeling machining center designed for mass finishing, surface peeling, oxide layer removal and milling of hardware, plumbing sanitary parts, automotive precision components, brass and aluminum die castings. Equipped with a complete set of Mitsubishi CNC servo systems and 8 groups of high-power ER32 motorized spindles for simultaneous processing, this machine features high-rigidity resin sand cast cross slide bed structure, three-axis high-speed linear transmission, micron-level repeat positioning accuracy and long-term stable durability.
It effectively replaces multiple single-head peeling machines, saves factory floor space and cuts labor costs, making it the ideal automated precision peeling equipment for mass production of sanitary fittings, auto spare parts and non-ferrous metal castings.

二、Machine Structure & Competitive Advantages

High-Rigidity Cast Body for Long-Lasting Precision

• Cross slide bed layout engineered for maximum strength, stability, and easy maintenance.
• Column, saddle, base, spindle box, and worktable crafted from high-strength resin sand cast iron with heavy box-type reinforcing ribs.
• Complete thermal aging treatment eliminates internal stress to prevent structural deformation under long-term heavy cutting.
• 6,000 kg heavy mass dampens high-speed operation vibrations, maintaining steady performance and lower failure rates.

8 Synchronous Spindles for Multi-Part High Efficiency

• Equipped with 8 sets of XINYATAI 5.5 kW ER32 motorized spindles.
• Direct motor connection eliminates transmission energy loss, providing strong torque and low operational noise.
• Max spindle speed reaches 24,000 RPM with Japanese precision angular contact bearings for high dimensional accuracy.
• Powered by 4 sets of 11 kW Sinovo spindle servo motors, optimized for steady high-speed peeling of copper, aluminum, and zinc alloys.

Three-Axis High-Speed Precision Feeding System

• Axis Travel (X / Y / Z): 600 x 500 x 500 mm
• Spindle Nose to Table: 90 – 650 mm (accommodates various workpiece heights)
• Linear Guides: Precision Taiwan HIWIN or PMI linear guides for high-speed, wear-resistant motion.
• Transmission: C3 grade precision ball screws (16mm lead) backed by 60° large contact angle bearings.
• Feed Speed: Rapid traverse rate up to 48,000 mm/min; cutting feed rate adjustable from 0 to 12,000 mm/min.
• Lubrication: Automatic timed & rationed lubrication pump station for linear guides and ball screws.

Complete Mitsubishi CNC Control System

• X & Y Axis Servo Model: Mitsubishi HG303S-D48
• Z Axis Servo Model: Mitsubishi HG303BS-D48
• Compatible with standard G-code programming with large memory capacity for swift program switching.
• Dual hardware and software travel limit protection prevents collision risks for safe operation.

Heavy-Duty Worktable for Multi-Workpiece Clamping

• Table Dimensions: 1820 x 450 mm with 500 kg maximum load capacity.
• T-Slot Specification: 3 – 18 x 130 mm for versatile fixture clamping.
• Allows multi-part clamping for simultaneous 8-spindle batch processing.
• Spindle Center to Column: 585 mm distance provides abundant clearance for oversized workpieces.

Micron-Level Machining Accuracy (JIS Standard)

• Strictly complies with Japanese JIS industrial standard specifications.
• Positioning Accuracy: ±0.005 mm per 300 mm travel
• Repeat Positioning Accuracy: ±0.005 mm per 300 mm travel

Full Safety Protection & Mass Production Options

• Fully enclosed housing with stainless steel telescopic guards protecting guides from dust and metal chips.
• Real-time spindle temperature monitoring display alerts cooling system issues to prevent thermal damage.
• Optional automatic sliding doors for robotic line integration and automated mass production.

三、Core Production Benefits

1. Higher Production Efficiency: 8 spindles operate simultaneously. Compared to single-spindle machines, it cuts equipment investment, factory space, and labor costs by 80%.
2. Stable & Consistent Precision: Imported spindles, Mitsubishi servo system, and JIS micron-level accuracy guarantee uniform finished size and lower rework costs.
3. Long Service Life & Low Maintenance: Stress-relieved castings, Taiwan precision transmission parts, and automatic lubrication support stable 24-hour continuous mass production.
4. Intelligent Mass Production Ready: Optional automatic door and temperature monitoring system support semi-automated or unmanned workshop layout.
5. Wide Compatibility: Large worktable and wide travel range support multiple workpiece types on one machine, with easy program switching for multi-model production.
