Ukaine firm purchases three machines from Danobat group
Ukraine-based NERGOMASH has recently purchased three machines from Danobat Group, which has its unit at India in Pune. The machines--VTC-1800 vertical lathe, VTC-3200 vertical lathe and FR-10000-W travelling column milling-boring machine—have been procured to optimise its production process and the precision of its components.
Speaking about advantages of using VTC-3200 vertical lathe, Vladimir Kushko, the technical manager of Nasosenergomash said, “Vertical lathes are used for machining pump bodies for the nuclear power sector, pumps for oil transportation and pumps for electric power stations. Their complexity lies in the precision of their parts. The largest diameters have to be within 0.01 mm tolerance (quality class 6). Machine precision and reliability are two very important aspects required by the sectors we work for, and high productivity is also essential.”
On how the company’s pump body production improved with the new VTC-3200 vertical lathe, Kushko said that there has been a great improvement as regards precision and productivity. Previously, the pump bodies were processed on six different machines to undergo all the machining operations required. With the VTC-3200, all the operations are carried out on just one machine and with a single clamping process. This has increased the company’s productivity, reducing the idle time needed for part clamping and has improved precision as there is only one clamping process.
The machine also includes a head with four turning positions, allowing four tools to be used with no stoppage times for tool change, and this optimises the machining times. He said that Danobat Group has been an exceptional partner. “We explained our machining problems and requirements to them and the group proposed a precise, highly productive solution. They showed great know-how and flexibility, adapting to our specifications and putting forward improvements that have a very positive effect on the end product,” Kushko concluded.
