Tong-Tai (Topper) Introduces a 20" Pallet Horizontal Machining Center - The HB500 at the IMTS-06 Show

VALLEY COTTAGE, NEW YORK (March 15, 2006): Tong-Tai (Topper) introduces a 20" pallet horizontal machining center - the HB500. This is the first of a series of horizontal machining centers the designs of which are based on proven concepts by well-established Japanese manufacturers. This design makes the machine suitable for general-purpose applications or high speed machining applications. The X & Y movement is on the column with the Z movement being on the table. This combination allows for sufficient area for chip removal in high speed machining applications.

The machine base is a 20" x 20" pallet with an automatic pallet changer. The maximum part dimension is 36" x 36" with a total maximum weight of 1,300 lbs. The standard indexing on the pallet is 1 degree. There is an optional 4th axis available. It has a 50 taper (HSK optional) built-in spindle with 30HP main motor and a maximum rpm of 10,000. External spindle cooling and coolant through the spindle is standard on the HB500. For high speed machining and high material removal applications, there is also a coolant wash inside the bed, coolant wash from the ceiling, an 8-piece coolant nozzle in front of the spindle and a fully enclosed splash cover to contain all the fluids and chips.

Strokes of the axis are X 32", Y 28", Z28" with a rapid 1990 ipm traverse. The machine has a Fanuc-18iM control with rigid tapping and capabilities of RISC chip, look ahead and Data Server for High Speed Machining applications.
Tong-Tai Seiki is a full line machine tool builder providing Standard Machines, Customized Machines and Special Purpose Machines in the US, Far East and China. It has offices in Taiwan, Mainland China, Thailand, Indonesia, Malaysia, Japan and USA. In the US, its machines are sold and serviced through a network of full service distributors throughout the country.

Tong-Tai started as a builder of machining lines for motorcycles in 1969. The principal products at this time were automatic turning machines and multi-spindle drilling and tapping machines. This basic background of building special purpose machines has been instrumental in providing the foundation of Tong-Tai being a machine tool builder rather than just an assembler of purchased components.

Tong-tai started building CNC turning centers in 1982 and advanced to horizontal and vertical machining centers in 1985. Knowledge to design and manufacture these machines was gained over 30 years of technical cooperation with various Japanese Machine Tool Builders. Since 1990 Tong-Tai had very close technical cooperation with Hitachi Seiki, one of the leading machine tool builders in Japan. Starting 1998, Tong-Tai was manufacturing and assembling machines for Hitachi Seiki, on an OEM basis, for export to USA, Japan and the world. Tong-Tai is also one of the few Taiwanese machine tool builders with ISO-9001 and ISO-14001 certification.
