Sachman TMC 130

The Sachman TMC 130 is a heavy-duty CNC horizontal boring and milling center representing the table-type variant in the Sachman TMC series. With a 130 mm spindle bore diameter, it is engineered for the most demanding large-part machining environments — including energy, mining, construction machinery, and heavy engineering sectors. Unlike the RAM series which uses a sliding ram carrier, the TMC 130 employs a table-type configuration where the workpiece is mounted on a precision CNC rotary table that travels in the X-axis while the headstock moves vertically (Y) and the column traverses horizontally (Z).

The TMC 130's structural design prioritizes maximum rigidity and thermal stability. The machine bed is a single-piece heavy cast iron structure with optimized rib geometry to resist deflection under the heaviest cutting forces. The column rides on precision-ground hardened guideways, and the headstock incorporates roller and angular contact bearing arrangements sized for the high radial and axial loads generated when boring or face milling large workpieces. The integrated CNC rotary table — a key differentiator from floor-type boring mill configurations — allows four-sided part access in a single setup, dramatically reducing setup time and improving geometric consistency across mating features.

Spindle performance is defined by a high-torque drive train capable of generating the sustained power needed for deep boring and heavy face milling in difficult-to-machine alloys. The 130 mm spindle nose accommodates large boring heads, shell mill arbors, and heavy-duty angle heads, giving the TMC 130 broad versatility across operation types. Variable spindle speed with fine resolution allows optimization for each tool and material combination, while the automatic tool changer with large magazine capacity supports complex multi-operation programs.

CNC control is provided via Siemens SINUMERIK 840D sl, offering the full suite of advanced cycles, 3D tool compensation, tilted plane machining, and integrated probing. The control's open architecture allows DNC integration for facilities running automated production cells. Remote monitoring and diagnostic capabilities are available, supporting predictive maintenance programs and reducing unplanned downtime.

The Sachman TMC 130 competes directly with comparable offerings from European heavy boring mill specialists and represents a strong value proposition for manufacturers who need Italian precision engineering combined with modern CNC sophistication. Its table-type architecture is particularly well suited for facilities machining heavy transmission housings, large gear cases, compressor frames, and structural components where repeatable accuracy across multiple machined faces is the primary performance criterion.
