Micro Milling Machine – μltraMill available with 3, 4 or 5 axes
μltraMill is a bench top micro milling machine capable of milling, drilling and grinding of a wide range of miniature components as well as machining micron sized surface features on components of up to 150 x 150 x 120 mm in size. Its unique construction, using air bearings and direct drives on all axes means that it can achieve outstanding dimensional precision, surface geometry and surface finish making it suitable for manufacturing small components and moulds used in the optical, medical and electronics industries.
- Aerostatic bearings used in conjunction with direct drives completely eliminates the noise and vibration produced by conventional drive elements such as gears, lead screws and couplings enabling exceptionally smooth axis motion and positioning accuracy.
- 150 000 rpm aerostatic spindle with a high efficiency synchronous DC Brushless motor provides smooth running with low thermal growth over a wide speed range.
- Vibration isolated natural granite base provides excellent thermal stability and damping capacity.
- PC based CNC control system with Windows platform and customisable HMI.
- Modular construction enables easy upgrade from 3 to 4 to 5 axes.
- Available in standard or customised designs.
- Complex miniature 3D components finish machined in one set up.
- Surface features as small as 20 x 20 x 1 μm deep.
- Surface finishes as low as 10 nm Ra on soft metal substrates.
- Tools with cutting tip diameters as low as 50 μm can be used with good machining rates and low risk of damage.
- Suitable for use with tungsten carbide, CBN, PCD and single crystal diamond tools.
- Suitable for machining soft materials such as aluminium, copper and plastic and hard or brittle materials such as glass, nickel and steel.
- Applications include high precision mould tools, small optical components, medical devices, transducers, watch components, micro printed circuit boards, electronic components and tribological components.
