This 4-spindle peeling machine is suitable for medium-volume production of non-ferrous metal precision components. Compared with 8-spindle DK850-8 model, it has smaller footprint, lower investment and flexible deployment for small batch multi-model production. It realizes synchronous processing of multiple workpieces in one clamping, effectively improving processing efficiency while keeping stable dimensional accuracy and low operation failure rate.
DK450-4 Four-Spindle CNC Peeling Machine
Description
一. Basic Profile
DK450-4 is a 4-spindle CNC peeling machine with cross slide bed layout, independently developed for small-batch precision peeling, deburring and oxide layer removal of brass, aluminum, zinc alloy hardware, sanitary fittings and auto parts. Equipped with full Mitsubishi CNC system, 4 sets of XINYATAI ER32 high-speed motorized spindles and Taiwan precision transmission components, it delivers stable high-speed processing, JIS standard micron-level precision and solid structural rigidity. Compact size and 3500kg lightweight design make it ideal for small & medium manufacturers with limited workshop space.

三、Structural and Performance Highlights
High-Rigidity Cast Frame
- All key components (base, column, saddle, spindle box, worktable) are resin sand high-strength cast iron with box structure and thick reinforcing ribs. All castings go through aging treatment to eliminate internal stress, ensuring long-term rigidity, stability and anti-deformation during continuous cutting. Easy daily maintenance.
Premium 3-Axis Transmission System
- Linear guides: Taiwan HIWIN/PMI linear rails for fast response and high precision.
- Drive: C3 grade precision ball screws with 16mm lead, supported by imported 60° large contact angle bearings to guarantee rigidity and precision retention.
- Centralized automatic timed quantitative lubrication system for rails and ball screws to reduce wear and extend service life.
High-Stability Spindle Assembly
- XINYATAI spindle unit built in spindle box, fitted with Japanese imported precision angular contact bearings with wide support span. Direct connection between spindle motor and spindle avoids power loss, featuring stable running, low noise and consistent batch processing accuracy.
Complete Safety Protection
- Stainless steel telescopic guards for X/Y/Z three-axis rails to block metal chips and dust, protecting transmission parts.
- Software & hardware dual safety travel limits to prevent collision.
- Full overall enclosure, fully meets international machinery safety and environmental standards.
