The real challenge of complex part machining

For many job shops and production lines, complex components such as hydraulic valve bodies, stepped shafts, and long shaft components require multiple operations on different machines – turning on a lathe, milling on a machining center, and sometimes drilling on a third machine. Each transfer between machines introduces alignment errors, requires additional setup time, and increases work‑in‑progress inventory. The HAIDI TX‑750HMY/1500 addresses this challenge by consolidating turning, milling, drilling, and tapping into a single machine, single clamping, and single CNC program.

Application 1: Hydraulic valve bodies

A typical hydraulic valve body requires turning of the outer diameter, boring of internal passages, milling of flats or locating faces, drilling of cross holes, and tapping of threaded ports. On a traditional turning center without live tooling, the part would be turned first, then transferred to a milling machine or machining center for secondary operations – each transfer risking misalignment and consuming valuable floor time.

On the TX‑750HMY/1500, the 12‑position BMT65 turret holds both stationary tools and live tools simultaneously. The C‑axis spindle indexes the workpiece to the required orientation, and the Y‑axis (with ±70 mm travel) provides the additional axis of movement needed to reach off‑center features. For a typical cast iron or steel valve body measuring 150 mm in diameter and 300 mm in length, the complete machining cycle can be reduced by 40–50% compared to multi‑machine processing.

Application 2: Automotive shafts with cross holes and keyways

Automotive shafts, such as transmission output shafts or hydraulic pump shafts, often require turning of multiple diameters, milling of keyways, and drilling of cross holes at specified angular positions. The keyways and cross holes must be precisely aligned to the shaft's rotational orientation.

On the TX‑750HMY/1500, the C‑axis provides the necessary angular positioning with 0.001° resolution. The operator programs the keyway milling operation, the spindle indexes to the correct angle, and the live tool completes the cut. The entire sequence – rough turning, finish turning, keyway milling, cross drilling, and tapping – runs automatically without operator intervention. For a typical 500 mm long shaft, the TX‑750HMY/1500 can complete all operations in under 10 minutes, with diameters consistently held within ±0.005 mm.

Application 3: Hydraulic pistons and rods

Hydraulic pistons and rods require turning of the outer diameter, facing of the end, grooving for seals, drilling of a center hole, and tapping of threads. The length can range from 300 mm to over 1,000 mm. On a manual or standard lathe, each feature requires careful operator adjustment, and consistency across a production batch is difficult to maintain.

The TX‑750HMY/1500's 1,500 mm machining length provides ample capacity for medium‑to‑long shaft components. The hardened box guideways and 30° slant bed ensure that the machine maintains alignment even when machining long, slender parts. The hydraulic tailstock supports the workpiece throughout the operation, eliminating deflection concerns.

How single‑setup machining improves your bottom line

Every time a part moves from one machine to another, several costs accumulate: handling labor, queuing time between operations, fixturing for each machine, and the risk of quality issues from datum loss. The TX‑750HMY/1500 eliminates these costs by completing all operations in one clamping. The Y‑axis, with its ±70 mm travel, is a key enabler for this capability. When combined with the C‑axis and live tool turret, the machine can reach any feature on the workpiece without repositioning.

For a shop processing 150 hydraulic valve bodies per week, moving from a three‑operation process (turning, then milling, then drilling) to a single‑setup process on the TX‑750HMY/1500 can reduce total processing time by up to 60% and free up significant machine capacity.

Practical preparation for buyers

Before the TX‑750HMY/1500 is delivered, users should prepare a level concrete floor capable of supporting the machine's 10,000 kg weight, provide a 3‑phase 380V 50Hz power supply with approximately 40–50 KVA capacity, ensure an overhead crane or forklift for unloading, and have hydraulic oil, way lubricant, and basic metrology tools ready. Standard delivery includes on‑site installation, operator training, and complete documentation – operation manuals, maintenance guides, electrical diagrams, and quality certificate.
