DCM Series Feature
- Excellent structural rigidityCast iron components use FEA (Finite Element Analysis) to optimize rigidity and anti-vibration properties. Prevents cutting resonance, prolongs tool life and increases work piece accuracy and production capabilities.
- Optimized spindle boxOptimized design, rectangular ratio 1:1.125 provides rigid Z axis travel. Spindle box interior has rib reinforcements to increase cutting and feeding rigidity and stability.
- Optimized Z axis balance systemTwin N2 tank counter-balance loop design. Driver set firmly attached to Z axis. Provides precision response to servo motor and high thrust machining requirements on Z axis.
- Optimized feeding systemX, Y, Z axes are coupled with heavy duty, high precision class P linear guideways, with 0.003-0.005 mm low friction, low viscosity, optimizes high driven sensitivity and increases great dynamic accuracy.
- Optimized feed structure systemThree axes coupled with class C3 precision ball screws. Properly pretension from the ends to reduce thermal displacement. Absolute value coordinate system eliminates structural complexity. Ballscrews are specially designed with anti-ram protection devices on the ends. Powerful spindle, high cutting capabilities.
- Powerful spindle, high cutting capabilitiesThe BT50 spindle, diameter 100mm, coupled with class P4 precision angular bearings reaches 6000rpm. High torque spindle motor with 1:4 precision high/low speed gear box satisfies cutting requirements in all fields with sufficient horse power and torque.
