Machining Solutions, Ultra-precision

Arhan Technologies Pvt Ltd offers Yasda ultra-precision Machining Solutions for world-class die and mould applications. Yasda is world’s leading manufacturer in ultra-precision jig borer machines. Yasda machines are the first choice of global customers looking for super precision machines in applications of dies and moulds, aviation, medical electronics, mobile dies, precision cylinder block/head machining requirements, etc. Established in 1929, the company has been focusing on manufacturing high precision machines, a complete range of vertical CNC jig borers, horizontal precision centres, 5-axis precision centres, and micro-centres for IT parts manufacturing. These machines are manufactured and assembled in strict temperature control of 1 degree. The company manufactures a full range of vertical CNC jig borers, YBM 640 V (table 600 x 400 mm), YBM950V (900 x 500), YBM9150V (1500 x 900), and YBM1218V (1800 x 1200). All Yasda machines employ through hardened box guide ways combined with roller pack bearings for smooth and high response, are designed for high precision dies and moulds as well as machine components, parts requiring jig boring accuracies. Yasda’s direct drive system utilises a diaphragm coupling that co-axially connects the spindle and the drive motor without causing any backlash. This design allows electric vibrations caused by the drive motor to be isolated and improves the spindle’s rotational accuracy because the spindle’s driving force does not work in the radial direction. The design provides low inertia from spindle, smooth, vibration free accurate rotation for fine grade machining, and vibration free machining increases productivity and tool life. Yasda machines have integrated column and top beam to stabilise high speed motion. All Yasda machines have rigid and unique symmetrical structure strong against thermal displacement and distortion realising constant high-precision machining for decades.
