SMTCL’s Brio Miller 8 CNC vertical machining center is available for machining complex parts demanding high precision such as plates, discs, shells and moulds. It performs a series of processes like milling, drilling, tapping, boring, reaming and contouring. Main components such as bed, table, slide carriage, column and spindle box are made of high-strength resin bonded sand casting. All structural components are optimised to improve rigidity and stability. Vibrations and deformations generated by cutting forces are effectively minimized. Guide way pairs use roller-type linear guide rails, which have the advantages of minimum friction, high sensitivity, low vibration at high speed, no creep at low speed and high positioning accuracy. Thus the accuracy and stability of the machine are highly improved.

The servo motors are directly coupled to the high precision ball screws via flexible couplings to achieve seamless transmission. Thus, feed flexibility, positioning accuracy and transmission precision are enhanced. The Z axis servo motor featuring automatic brake function holds the motor shaft when power shuts down.

Standard features are a Siemens Sinumerik 808D control, an auto lubrication system, an umbrella-type tool magazine and a chain-type chip conveyor. The Brio 8 is said to shorten your production period, improve precision, reduce labour costs, reduce tooling investment, maximise floor space and reduce energy usage
