CNC Milling-Engraving Machines
Sunita Engineering Corporation offers CNC Milling-Engraving Machines, EN Series/ Fx Series. It is a indigenously manufactured 3-axis/ 4-axis and 5-axis Milling-Engraving machine with built-in, stand-alone 40 MIPS (Million Instructions per second) dedicated controllers (stepper as well as servo). Moving on precision ball screws and linear motion devices, it gives a smooth motion with resolution of 0.01 mm (stepper controller) or 0.005 mm (servo controller). Different configurations of the machines are available which makes them suitable for toolroom applications as well as production type (repetitive nature) of jobs. The smallest machine offers working area of 300 X 200 X 60mm while the largest machine offers 450 X 600 X 60 mm. Machines come with 10,000 rpm, 330 Watts rigid spindle which can hold tools upto 8mm shank diameter. High Frequency embedded type spindles (750 Watts) and rpm ranging from 12,000 to 25,000 rpm are also available as option. The machine offers feed rates upto 1.2 m/min (stepper driven) and 3.0 m/min (servo driven) to facilitate fast cutting. Its compact and rigid structure facilitates its use in variety of industries like spark-erosion electrodes, biscuit rollers, punch dies, vacuum forming, soap dies, shoe-soles, watch-cases, jewellery, rubber stereos, PVC labels, coining dies, embossing dies, sign making, gift articles, mementoes, inlays, forging dies, wooden and CI patterns. The floor space occupied by the machine is 1 cubic meter (maximum) and the power consumption can be as low as 500 Watts to 1,500 Watts. The machine works on standard 440V, 50 Hz three phase A.C. supply and can also be configured to work on 220V, 50 Hz single phase A.C. supply. The machines come with accessories like simultaneous 4th axis as well as simultaneous 5th axis, Engraving Software, Personal Computer, single lip tool grinder, engraving tools, coolant equipment, digitiser (reverse engineering solution), etc.
