Our Machinery
The Doosan DNM6700
Is a three-axis CNC (Computer Numerical Control) milling machine designed for high-precision metal cutting and fabrication operating on three axes (X: 1300mm, Y: 670mm, Z: 760mm) to move the cutting tool along multiple dimensions.
With a large table, it accommodates bigger workpieces, ideal for applications involving large components.
The DNM6700 offers stability and minimal vibration ensuring accuracy on complex parts that demand tight tolerances and can perform various milling tasks such as:
- Drilling
- Facing
- Contour milling
- Slotting
- Pocketing
The Mori Seiki 2-axis CNC lathe
Is a precision machine designed for automated turning and shaping of materials. It operates on two axes (X for horizontal tool movement, Z for lengthwise movement along the workpiece) and accommodates parts up to one meter in length between centres.
Ideal for high-precision tasks, it performs operations like turning, facing, threading, and boring with consistent accuracy by following programmed instructions.
Manual lathe with 1500mm between centres
Is a hands-on machine for turning, shaping, and cutting materials. Capable of handling workpieces up to 1.5 meters long, it’s ideal for larger parts like shafts.
Operated manually, it allows precise control over the tool’s speed, depth, and movement, performing tasks like turning, facing, threading, and boring with flexibility for custom work.
