Heavy engineering demands machines that don't compromise

In power generation, mining, shipbuilding, and machine tool manufacturing, production downtime is not just an inconvenience – it is a significant revenue loss. Components such as turbine housings, gearboxes, cylinder blocks, crusher frames, and machine tool beds require machines that deliver consistent accuracy, shift after shift, year after year.

This is the environment for which HAIDI horizontal boring mills are built.

Application 1: Power generation – turbine housings and generator frames

Turbine housings and generator frames are among the largest and most demanding components in heavy engineering. These parts require precision boring of bearing housings, milling of mounting faces, and drilling of bolt hole circles – all with tight tolerances and excellent surface finishes.

On a HAIDI horizontal boring mill with a 130 mm spindle, the workpiece is clamped once on the rotary table. The C-axis indexes the part to present each face to the spindle, and the machine performs rough boring, finish boring, face milling, and drilling in a single setup. The result is consistent accuracy across all features – no alignment errors from multiple setups, no handling damage to heavy castings.

Application 2: Mining – crusher frames and mill components

Crusher frames and mill components for the mining industry are massive castings or fabrications weighing tens of tons. These parts require boring of bearing bores, milling of mounting surfaces, and drilling of bolt holes – often with interrupted cuts that challenge less rigid machines.

The rigid cast iron construction of HAIDI horizontal boring mills absorbs the shock of interrupted cuts, preventing chatter and maintaining surface finish. The extending boring spindle (W-axis) allows deep reach into the workpiece, accessing internal features that would be impossible with conventional machines. The result is a component that meets specifications without rework.

Application 3: Shipbuilding – propulsion shafts and hull structural elements

Shipbuilding requires machining of large, heavy components such as propulsion shafts, stern tube bearings, and hull structural elements. These parts often exceed the capacity of standard machine tools.

HAIDI offers floor-type horizontal boring mills for the largest shipbuilding applications. The column moves along guideways built into the workshop floor, allowing machining of workpieces weighing hundreds of tons. The spindle reaches deep into the workpiece, performing boring, milling, and drilling operations with the precision required for marine applications.

Application 4: Machine tool manufacturing – beds, carriages, and columns

Machine tool manufacturers use horizontal boring mills to produce the beds, carriages, and columns of their own machines. These components require high geometric accuracy – straightness, flatness, and squareness – because they form the foundation of other machine tools.

On a HAIDI horizontal boring mill, the large work envelope accommodates beds up to several meters in length. The precision guideways and CNC control ensure that machined surfaces are straight and flat within tight tolerances. The result is a component that serves as a stable foundation for another precision machine.

The HAIDI difference – quality you can rely on

In-house foundry – HAIDI casts its own beds, columns, and major structures in its own foundry. The castings undergo prolonged thermal aging to eliminate internal stresses – a process that ensures dimensional stability for decades.

Precision spindles – HAIDI horizontal boring mills are available with 90 mm, 110 mm, or 130 mm spindles, with spindle speeds up to 2,500–4,000 r/min and spindle motors delivering 22–30 kW of continuous power.

CNC flexibility – Siemens, Fanuc, or GSK controls according to customer preference.

Rigorous testing – Every machine is tested under load before leaving the factory.

Direct-from-manufacturer advantages

Buying directly from HAIDI Machine offers several advantages over purchasing through intermediaries:

Competitive pricing – No dealer markups. You pay factory prices.

Custom configuration – Spindle selection, table size, CNC system, and tooling tailored to your specific parts.

Technical support – HAIDI engineers provide assistance in Russian, making communication straightforward.

Spare parts availability – Critical components are stocked for quick delivery.

Full documentation – Operation manuals, maintenance guides, and electrical diagrams are provided.

Warranty coverage – Standard warranty with responsive claims handling.

New vs. used – why HAIDI is the smarter choice

The used machine tool market is full of tempting deals on horizontal boring mills. But experienced buyers know that the purchase price is just the beginning. A used horizontal boring mill almost certainly needs:

Spindle bearing replacement – tens of thousands of dollars

Guideway reconditioning – costly and time-consuming

Ball screw replacement or refurbishment – expensive

Hydraulic system overhaul – more expense

CNC control updates or retrofits – significant cost

Unplanned downtime during repairs – lost revenue

A new HAIDI horizontal boring mill comes ready to run. No hidden wear. No immediate repairs. No unknown history. Full warranty. Factory support. Modern CNC control.

When you add up the total cost of ownership over three to five years, the new HAIDI machine is often the more economical choice.

Who should choose HAIDI horizontal boring mills?

Shops producing turbine housings, gearboxes, cylinder blocks, and crusher frames

Manufacturers in power generation, mining, shipbuilding, and machine tool building

Factories upgrading from older or manual boring machines

Job shops that cannot afford unplanned downtime

Any shop planning to keep the machine for 10+ years
