Designed around modularity for the market’s heavy-cutting needs, the BMC-135FTS high-load mill-turn boring machine from FATEK, a FEMCO group company, features a high-load worktable and is easy to assemble and maintain. It is expected to be a focus for international buyers at TIMTOS 2025 (Nangang Hall 1, 1F, booth I0306).

With more than 76 years of history, the FEMCO group spans steel, engineering, machine tools and golf shafts, making it a diversified steel manufacturer. FATEK is the group’s machine tool business, specializing in machine tool R&D and manufacturing. Building on the parent company’s experience, it serves the automotive, aerospace and petrochemical industries and provides dedicated fixtures, machining optimization and production line integration to customer needs. Its industry-first 3D modular management system quickly integrates drawings, materials and processes so component specifications can be adapted to each customer’s requirements.

Building on its lead in horizontal boring mills and guided by President Liu Yu-chen’s motto “experts in raising quality and productivity”, the group drew on well-known foreign designs so the facing head and spindle can be offset vertically. For heavy cutting, an extension sleeve can be fitted to the spindle to prevent chatter and ensure accuracy.

The BMC-135FTS has a simpler design that makes assembly and maintenance easier. Its modular concept means that, once validated, each technology can be applied quickly to other machines, giving sales more flexibility, adding product value and opening the high-end market.

Its key innovations are the high-load worktable and a facing head with turning capability. Large parts used to require complex multi-step processes prone to error and could not be finished on one machine. With a turning facing head, boring, milling and turning can be done on a single machine, reducing errors between operations. To carry heavy parts, FEMCO developed its own hydrostatic bearing technology instead of costly, long-lead-time rotary table bearings, and commissioned an academic partner to perform Ansys static stiffness analysis, achieving excellent accuracy and quality.

The machine also integrates several smart features, among the most innovative in the industry, for which multiple invention patents have been filed. To simplify carbon accounting, current transformers on the power input feed a power-monitoring module that shows three-phase voltage, current, frequency, power and total consumption on the controller, so operators can track energy use in real time and calculate the machine’s carbon emissions.

With combined milling and turning, the BMC-135FTS serves a wide range of machining needs, mainly components for the petrochemical industry, large pumps, and pipes and valves for water and power grids. It handles most machining processes; the machine body and facing head are made entirely in-house and have been sold in many countries. FEMCO is now improving spindle rigidity, machining range and ease of use, and pairs the machine with a smart app-based digital service so it can respond flexibly to market needs and stand out from competitors.
