Overview

The Soraluce TA-A 35 is a bed-type milling and boring machine built in the Basque Country of Spain by Soraluce, a subsidiary of the Danobat Group and one of Europe's most established builders of large-capacity milling and boring equipment. With 3,500 mm of X-axis travel, 1,200 mm of Y-travel, and 1,250 mm of Z-travel, the TA-A 35 handles large workpieces on its 3,800 x 1,000 mm table that supports up to 10,000 kg. The machine occupies a unique position between a standard VMC and a floor-type boring mill — more rigid and capable than the former, more compact and affordable than the latter.

The spindle delivers 24 kW of power at speeds up to 5,000 RPM through a DIN-69871-AD taper interface, with an automatic indexing head that positions in 2.5° increments for angular machining operations. This angular head capability is a key differentiator: it enables the TA-A 35 to machine angled bores, faces, and features that would require re-fixturing on a standard 3-axis machine. Combined with the 40-tool automatic tool changer, the machine can run complex multi-feature programs without operator intervention.

Feed rates reach 10,000 mm/min on cutting operations, with rapid traverses up to 30,000 mm/min on all axes. At 25,000 kg (55,116 lb), the TA-A 35 has extraordinary mass for its class, which translates directly to vibration damping and surface finish quality during heavy milling and boring operations. The machine runs on a Heidenhain TNC 530 control — a premium CNC platform widely used in European mold and die shops, with strong support for five-axis contouring, shop-floor programming, and conversational operation.

Soraluce has built milling and boring machines since 1962, and the TA series is their most popular product line for medium-to-large workpiece machining. The TA-A 35 competes with the Correa A-30, Zayer 30KF-AR, and Nicolas Correa CF-22 in the European bed-type milling market. For North American buyers, it offers an alternative to the Kuraki and Toshiba horizontal boring mills, with the advantage of a fixed bed and moving column architecture that maintains accuracy across the full work envelope. Shops machining large mold bases, structural components, energy equipment, and heavy fabrications will find the TA-A 35's combination of travel, table capacity, and angular head capability compelling.

Strengths & Limitations

Strengths

3,500 mm X-axis travel and 3,800 x 1,000 mm table handle large structural components, mold bases, and heavy fabrications
10,000 kg table load capacity supports the heaviest castings and weldments without stability concerns
Automatic 2.5° indexing head enables angular boring and milling operations that would require re-fixturing on standard machines
25,000 kg machine weight provides exceptional vibration damping for superior surface finish during heavy cuts
Heidenhain TNC 530 control is a premium platform with strong conversational programming and five-axis contouring support
40-tool ATC enables complex multi-feature programs to run without operator tool-change intervention

Limitations

24 kW spindle power is moderate for the machine's size — shops doing very heavy roughing may want the higher-power TA-A variants
5,000 RPM maximum spindle speed limits high-speed machining of aluminum and small-diameter tooling applications
25,000 kg weight requires significant foundation preparation and rigging logistics for installation
Soraluce's North American dealer network is limited compared to Japanese or American machine tool brands
Heidenhain controls, while excellent, have a smaller operator pool in North America compared to Fanuc or Siemens

Best For

Mold and die shops machining large mold bases and die sets requiring precision boring and angular face milling Energy equipment manufacturers machining turbine casings, valve bodies, and large structural frames Heavy fabrication shops milling and boring large weldments and structural components up to 10,000 kg Aerospace structural component shops machining large aluminum and titanium frames and fittings General precision machining operations needing bed-type milling capability beyond the reach of standard VMCs

Frequently Asked Questions

01 What is a bed-type milling machine and how does it differ from a VMC?

A bed-type milling machine has the table mounted on a fixed bed with the column moving along the X-axis, whereas a VMC moves the table in X and Y. The bed-type design maintains consistent accuracy regardless of table load because the workpiece weight doesn't affect axis geometry. This makes bed-type machines ideal for heavy workpieces — the TA-A 35's 10,000 kg table load would severely affect accuracy on a standard VMC.

02 How does the automatic indexing head work?

The indexing head rotates the spindle axis in 2.5° increments around two axes, allowing the tool to approach the workpiece at almost any angle. This enables boring angled holes, milling angular faces, and reaching features that would be inaccessible with a fixed vertical or horizontal spindle. The indexing is automatic and programmable through the Heidenhain control.

03 How does the TA-A 35 compare to a horizontal boring mill like the Toshiba BTD-200QH?

The TA-A 35 has a larger work envelope (3,500 mm X-travel vs 1,500 mm) and higher table load capacity (10,000 kg vs 4,000 kg). The Toshiba excels at precision boring work with its W-axis quill and rotary table, while the Soraluce is more versatile for general large-workpiece milling and boring. The TA-A 35's angular head gives it multi-angle capability without a rotary table. Choose the Toshiba for precision boring; choose the Soraluce for large-envelope milling and boring.

04 What maintenance does the TA-A 35 require?

Regular maintenance includes way lubrication system checks (weekly), spindle bearing monitoring (quarterly), and Heidenhain scale cleaning (annually). The automatic lubrication system handles most daily requirements. Plan for an annual service visit from Soraluce or their authorized dealer for geometry checks and software updates. Total annual maintenance budget is typically $5,000-$8,000 excluding tooling.

05 Is the TA-A 35 suitable for five-axis machining?

The standard TA-A 35 with the 2.5° indexing head provides 3+2 positioning capability (three continuous axes plus two indexed rotary axes). This handles most angular machining needs. For true simultaneous five-axis contouring, Soraluce offers models with continuous rotary axes, but the TA-A 35 is primarily a 3+2 machine. For most boring and milling applications, 3+2 capability is sufficient.
