tongil grinding machine (gu series)
DESCRIPTION
The TIC which stands for the "Tongil Industries Company" was established in 1988 as an overall heavy industry company to serve the South Korean industry in 3 business fields; Machine Tool, Ball screw, and Automobile Components. Our company is the leading player in the Korean market for Universal Cylindrical Grinding Machines, both manual and NC type, with each holding 60% of domestic market share from the early 2000's. After our successful exhibit at the EMO 2011 Shows in Hanover along with our representative, TIC-Europe, we now seek to serve the US market. With highly experienced customization skills, flexibility in the process of manufacturing, quality and precision of our grinding machines, TIC did OEM for domestic major players such as Hyundai-WIA and currently does OEM for a well-known Japanese Grinding Machine Company.TRANSCRIPT
