[EAST WINDSOR, CT – MAY 2026] – Koma Precision, the largest distributor of NC rotary tables and indexers in North America, will feature its entire line of D’Andrea Boring and Facing solutions in Booth #338754 South Hall during IMTS 2026 (September 14-19 at McCormick Place, Chicago, Illinois). Additionally, Technical Product Manager Jesse Meade will present “Do More with the Mill You Have: U-Axis Turning on CNC Mills” on Thursday, September 17th from 3:14-4:10 pm CST, further sharing the company’s deep expertise in maximizing the production capacity of the machines in the shop floor.
Koma has partnered with D’Andrea Precision Tools (Lainate, Italy) to be the exclusive distributor of D’Andrea’s Boring and Facing Solutions in the United States and Mexico.
In addition to installation and training, Koma offers its strong support and service by factory-trained technicians on all D’Andrea products, ensuring smooth integration and optimal performance. D’Andrea’s manual, semi-automatic and fully NC-controlled systems are compatible across all common machine tool interfaces and the core products seamlessly interface with one another, eliminating costly and time-consuming workarounds.
The System Backbone
D’Andrea’s modular MHD System, is the backbone of the D’Andrea product line. Built around a proprietary patented connection, each boring head in the system provides the concentricity necessary for high-precision applications. The MHD’s arbors, extenders, reducers, and adapters are shared across its core sizes ranging from the TRM micro-fine boring heads with micrometric radial adjustment to the TRC centesimal fine boring heads for precision finishing, the digital TRE fine boring heads with electronic readout for accurate measurement, and the double-bit TS rough boring heads for aggressive material removal.
Beyond the MHD system, D’Andrea is well-known for its high-precision line of boring heads, most of which use the same adapters and arbors as those in the MHD system reducing standalone tooling costs across a wide range of machines. For example, the traditional TA-SENSITIV manual heads for boring and facing operations provide reliable and repeatable facing and boring on conventional CNC machines while the AUTORADIAL automatic facing heads execute a complete facing cycle automatically, allowing standard machining centers to complete operations that would otherwise require a turning center or dedicated facing attachment.
Adding an Extra Machining Axis
The TA-CENTER heads add a fully programmable U-axis (radial slide) to any machining center and are compatible with automatic tool change changers. The slide movement is controlled by the machine’s own U-axis output eliminating the need for a separate controller or PLC. Because of this, a machine equipped with a TA-CENTER head can consolidate operations that would otherwise require a dedicated turning center. Shops working in the aerospace, oil and gas, and automotive industries will appreciate that complex internal profiles can be precisely bored in one setup and that the head is stored in the tool magazine much like all other tools in their inventory. For machines without an automatic tool changer, the TA-TRONIC heads feature a motor integrated into the head body itself. The motor then connects to the machine’s U-axis numerical control making the head fully programmable for all radial positioning moves. When a standard boring bar simply cannot reach the large diameter precision boring and facing process at hand, the U-TRONIC large-format NC heads fit the bill. Connected to a machine’s U-axis for precision radial slide control, the U-TRONIC line ranges from 360 mm to 1000 mm in diameter and special versions available to 1600 mm with an internal coolant passage to bore through even the toughest materials. They can be mounted manually, automatically or via palletized tool change systems.
Holding All of the Tools
The ability to maintain one single boring head inventory with interchangeable, modular components is a boon to shop’s that prefer to run leanly and efficiently. D’Andrea’s PSC modular and single-body toolholders feature an ISO 26623-compliant polygonal-tapered spindle interface for exceptional rigidity under demanding cutting conditions helping shops to meet the requirement for their boring, milling, drilling and boring machines, lathes (tapping) and machining centers. The PSC system, offered in modular and single-body options that connect directly to the MHD’ line via dedicated adapters allowing shops to add PSC arbors to their existing MHD’ components and eliminating the need to maintain two separate boring head inventories.
D’Andrea’s BHT cross bar system (250 mm to 1000 mm) and U-TRONIC heads (360 mm to 1600 mm) cover the full range of large-diameter boring and facing challenges that shops face in aerospace, energy, naval and heavy equipment manufacturing. A single BHT bar body with interchangeable cartridge kits covers roughing and finishing in one setup. Additionally, because they are compatible with the MHD’ system, the bars can be used across multiple machines without dedicated adapters, again, streamlining operations and cutting down on unnecessary inventory. Further, in the same vein, the MONOFORCE high-precision ultra-tight toolholders take it a step further offering high-gripping for demanding milling operations where conventional ER collet holders are insufficient. Ideal for aggressive roughing cycles or high-torque finishing on difficult materials, these toolholders are compatible with a variety of spindles across a mixed machine shop floor. Rounding out the D’Andrea toolholder line are the MONOd’ single-body integral collet chuck line and the THT turning modular toolholders for stationary tool turning operations on large machining centers and horizontal boring mills.
The addition of the D’Andrea lines complements Koma’s existing high-precision machine tool accessory offerings including complementing its offerings of rotary tables, angle heads, robotic part loaders and other automation-ready technologies designed to improve manufacturing efficiency, accuracy, and process consolidation.
“Our customers are looking for ways to reduce setups, increase spindle uptime, and maximize the capabilities of their existing machine tools. The addition of D’Andrea Tooling strengthens our ability to support those goals with proven high-performance solutions backed by the application expertise and service Koma Precision is known for,’ said Koma president Dave Meo.
