A straight copy of the high-class American Hardinge HLV-H toolroom lathe, the origins of the Alex-Tech are obscure - save for the fact that it was built in Taiwan by Alex-Tech Machinery Industrial Co., Ltd at Factory No.90-2, ShenChou Road, Shen-Kand, Shiang, Taichung Hsien (an address also common to the HLV-H lathe branded as the "Feeler".
The HLV-H has also been copied by several Taiwan firms including Barer, Cyclematic, Sharp, ProMach and 'South Bend' In addition, some of these makers have supplied machines with "alternative" branding for distribution by dealers worldwide. Feeler was the brand name used by the "Fair Friend Company Limited", originally of 11/F No. 665, Tun-Hwa South Road, Taipei, Taiwan with a factory at No. 805, Chung-Shan Road, Shen-Kang Shiang, Taichung-Hsien, Taiwan. Sharp's copy was beautifully made and sold as standard with a hardened bed and a 5 h.p. Japanese Yaskawa drive; however, they also offered the "Acra", a less well-finished model with a soft bed and minor changes to cut production costs.  ProMach, of whom few details are known, referred to their version as the "ProLathe" and sold it until at least the mid-1990s, and possibly later. The "Victor", made as the standard CTL-618, the Cyclematic CTL-618EM and CTL-618EVS with an improved electronic variable-speed drive, was by an unknown manufacturer, but distributed through the Taiwan Machinery Trade Centre in California.
