Overview
The Sachman T80 RAM is a heavy-duty CNC floor-type boring and milling machine produced by Sachman S.p.A., an Italian manufacturer based in Brescia with a long history in large-format boring and milling equipment. The T80 RAM designation indicates the machine's core specification: a floor-type (T-type) configuration with an 80-series platform — denoting the heavy machine class — equipped with a RAM-type quill spindle carrier. This architecture is specifically engineered for heavy boring, facing, and deep-pocket milling on large castings, fabrications, and forgings in the steel, energy, and heavy engineering sectors.
The Sachman T80 RAM features a 110 mm (4.33 in) boring spindle with a maximum spindle speed of 2,500 RPM and a continuous spindle power of 45 kW (60.3 HP). The RAM quill provides 600 mm (23.6 in) of CNC W-axis stroke for deep boring operations without repositioning the column. The floor-type column traverses on precision-ground hardened guideways in the X-axis, with Y (vertical) travel of 3,000 mm (118.1 in) and Z (spindle carrier horizontal) travel of 1,200 mm (47.2 in). A CNC rotary table provides B-axis positioning. The machine uses linear scale feedback on all axes for direct positional measurement, achieving ±0.008 mm (±0.00031 in) positioning accuracy.
Sachman configures the T80 RAM with either a Heidenhain iTNC 640 or Siemens SINUMERIK 840D sl control, providing 4-axis simultaneous interpolation and optional 5-axis capability with an angular milling head. The machine structure — column, bed, and crossrail — is made from high-strength cast iron with extensive ribbing and FEA-optimized section profiles for maximum static and dynamic stiffness. An automatic tool changer holds 60 tools standard (80 optional) in a chain-type magazine. High-pressure coolant through the spindle is standard.
New Sachman T80 RAM machines are priced from approximately $750,000 to $1,500,000 depending on X-axis travel length, table size, and control selection.

Strengths & Limitations
Strengths
- 110 mm spindle with 45 kW continuous power and a 600 mm RAM quill stroke provides an exceptional combination of power and reach for heavy boring in deep castings without column repositioning
- Linear scale feedback on all axes delivers direct positional measurement immune to ball screw thermal error, maintaining ±0.008 mm accuracy over long production runs
- FEA-optimized cast iron column and bed structure provides maximum static rigidity for heavy interrupted cuts on large castings where machine deflection would compromise bore accuracy
- 60-80 tool ATC capacity enables complex multi-operation programs combining boring, milling, drilling, and tapping in a single setup without manual tool changes
Limitations
- Maximum 2,500 RPM spindle speed limits the T80 RAM's capability for high-speed finish milling of aluminum and soft materials compared to machining centers
- Sachman's market presence is more concentrated in Italy and southern Europe; North American customers should verify service support and spare parts availability with local representatives
- Floor-type installation requires significant foundation preparation and site planning, adding months to the pre-production timeline

Frequently Asked Questions
01
The 'RAM' in the machine designation refers to the RAM-type quill carrier configuration. In a RAM-type boring mill, the W-axis quill (boring bar extension) is housed in a square or rectangular cross-section ram that slides horizontally from the spindle head carrier. This configuration provides greater rigidity and stiffness than a round quill design, particularly important for heavy boring cycles where quill deflection under cutting forces must be minimized. The T80 RAM's 600 mm RAM stroke provides the deep reach of a round quill design with the added rigidity of the square RAM cross-section.
02
Sachman's primary markets are heavy engineering, energy and oil-and-gas, power generation, steel and metals, and general machining of large parts. The company's floor-type boring mills are used extensively in Italian and European industrial manufacturers producing large castings, fabrications, and forgings. Sachman has also exported machines to customers in the Middle East, South America, and Asia serving the energy and heavy equipment sectors.
03
The linear scale feedback system (typically Heidenhain or Renishaw glass scales) measures actual axis position directly at the machine guideway rather than inferring position from ball screw rotation. This eliminates positional errors caused by ball screw thermal expansion, backlash, and pitch error that accumulate over long travel distances. On a floor-type boring mill with 4,000-10,000 mm X-axis travel, direct linear scale feedback can improve positional accuracy by 50-80% compared to ball screw encoder feedback alone.
04
Yes. Sachman offers an angular milling head attachment for the T80 RAM that provides a second rotation axis (A-axis) for compound-angle milling. Combined with the CNC B-axis rotary table, this creates a 5-axis (3+2 positioning) capability for milling angled faces, inclined bores, and compound-angle features. For full simultaneous 5-axis machining, Sachman offers a universal milling head option. Both head types mount to the RAM's standard spindle interface.
05
Sachman S.p.A. is based in Brescia, in the Lombardy region of northern Italy — a region with a long tradition of heavy machine tool manufacturing. The company has been producing floor-type boring and milling machines for several decades, with a product range that includes table-type, floor-type, and RAM-type boring mills in various size classes. Sachman's machines are marketed primarily through Italian and European machine tool dealers and are known in the heavy industrial market for robust construction and good price-to-performance ratios.
