Overview

The Sodick AQ750LH is the tall-clearance variant of the AQ750L, purpose-built for shops that need to combine the AQ750L's 750 x 500 mm X/Y travel with a substantially increased Z-axis capacity. While the standard AQ750L provides 300 mm Z clearance, the AQ750LH extends this to 400 mm, accommodating tall die shoes, thick mold base sets, and aerospace structural components whose height exceeds what a standard-format large wire EDM can accept. This makes the AQ750LH a specialized but highly productive tool for industries where tall workpieces are the norm rather than the exception.

The AQ750LH retains all of the core technology of the AQ750L: direct-drive linear motors on the X, Y, U, and V axes, the SP43A power supply with e-pak discharge technology, and Sodick's cast iron and granite composite machine bed. The 10-year positioning accuracy guarantee that distinguishes Sodick's linear motor machines from ball-screw alternatives applies in full. Positioning accuracy of ±0.001 mm is maintained across the entire 750 mm X-axis travel, where thermal effects are most pronounced on large-format machines.

The extended Z-axis on the AQ750LH has direct implications for the SP43A generator's operation. Cutting tall workpieces — particularly at heights above 300 mm — creates more challenging flushing conditions as dielectric must travel a longer path through the cut. Sodick engineers the e-pak discharge circuit specifically to adapt to these conditions: the generator's real-time gap sensing and energy modulation compensate for the flushing variation between the top and bottom of tall cuts, maintaining consistent cutting speed and surface quality while minimizing wire breaks that would require re-threading and interrupt unattended operation.

The AQ750LH is priced at a premium to the standard AQ750L, typically in the $270,000–$350,000 range. It competes with the Mitsubishi MV2400SL, GF AgieCharmilles Cut 2000 X tall configurations, and Fanuc ROBOCUT α-C800iC in the large-format tall-workpiece wire EDM segment. For heavy stamping die shops, extrusion die manufacturers, and aerospace suppliers whose workpieces regularly exceed 300 mm in height with footprints spanning 600–750 mm, the AQ750LH is among the most capable and durable machines available.

Strengths & Limitations

Strengths

400 mm Z-axis clearance opens the machine to tall die shoes, thick mold bases, and large aerospace structural sections that standard AQ750L cannot accommodate
Linear motor drives on all four axes maintain ±0.001 mm accuracy across the full 750 mm X-travel — no ball screw degradation on the industry's most demanding large-format work
SP43A e-pak generator's adaptive discharge management handles tall-workpiece flushing challenges better than fixed-parameter generators, reducing wire breaks on 300–400 mm height cuts
2,000 kg workpiece capacity supports very heavy die blocks and multi-part fixtures without special fixturing workarounds
Cast iron and granite composite bed provides vibration damping that sustains surface finish quality on skim passes across large part areas

Limitations

Premium price of $270,000–$350,000 over the standard AQ750L requires clear justification from workpiece height requirements — shops whose parts stay under 300 mm should buy the AQ750L instead
At approximately 7,200 kg, the AQ750LH demands substantial floor loading capacity and specialized rigging for installation
±15° taper range is the same as the standard AQ750L — for extreme-taper applications on large, tall parts, alternative configurations should be evaluated with Sodick's applications team

Best For

Heavy stamping die shops whose die shoe assemblies regularly exceed 300 mm in height, requiring full 750 x 500 mm X/Y travel simultaneously with tall clearance Extrusion die manufacturers producing large-profile dies and die holders where both the horizontal footprint and vertical height of the workpiece exceed standard machine limits Aerospace structural component suppliers cutting titanium and Inconel blanks that are both wide (600+ mm) and tall (300–400 mm) in a single fixturing Precision forging die makers working in die block configurations where height cannot be reduced through re-fixturing and where accuracy requirements demand linear motor performance

Frequently Asked Questions

01 What is the difference between the AQ750L and AQ750LH?

The AQ750LH is the tall-clearance variant of the AQ750L. The primary difference is Z-axis capacity: the AQ750LH provides 400 mm of Z clearance compared to 300 mm on the standard AQ750L. All other specifications — X/Y travel (750 x 500 mm), linear motor drives, SP43A e-pak generator, workpiece weight capacity (2,000 kg), and positioning accuracy (±0.001 mm) — are identical. The AQ750LH is approximately $30,000–$50,000 more expensive than the AQ750L. The H designation in Sodick's naming convention consistently refers to the extended-height configuration across their AQ and AG product lines.

02 How does tall-workpiece cutting affect wire EDM performance?

Tall workpieces create flushing challenges because dielectric fluid must travel a longer path through the cut. At 400 mm height, maintaining consistent flushing pressure and flow across the full cut height is significantly more complex than at 100–200 mm. Incomplete flushing leads to recast layer buildup, inconsistent surface finish, and elevated wire break frequency. Sodick addresses this on the AQ750LH through the SP43A e-pak generator's real-time adaptive discharge control, which senses gap conditions and modulates energy delivery to compensate for flushing variations. For best results on very tall cuts, experienced EDM programmers also use reduced cutting speeds and enhanced flushing setups.

03 Can the AQ750LH cut stacked workpieces up to 400 mm?

Stacked cutting at the full 400 mm Z height is technically possible but requires careful setup. Each part in the stack must be precisely aligned, gaps between parts must be minimized to avoid flushing discontinuities, and the SP43A generator parameters must be adjusted for the cumulative stack height. Sodick's application engineers can advise on stacking configurations. As a practical matter, most shops use stacked cutting on the AQ750LH at heights up to 200–250 mm and reserve the full 400 mm capacity for single large workpieces.

04 What wire types are recommended for 300–400 mm height cuts?

For tall-workpiece cutting in tool steel (D2, H13, S7), 0.25 mm coated wire (zinc-diffused or stratified wire) provides the best combination of cutting speed, flushing efficiency, and wire break resistance. The coated wire's superior surface diffusion characteristics improve flushing in tall cuts compared to plain brass wire. For carbide inserts within large die assemblies, 0.20 mm brass wire offers better cut definition. Sodick's LQ controller technology tables include parameters specifically optimized for tall workpiece cutting with common wire types.

05 How does the AQ750LH compare to the Sodick AG100L for tall workpieces?

The AG100L offers 1,000 x 800 mm X/Y travel with a standard 400 mm Z height, making it the natural comparison for shops needing both maximum travel and tall clearance. The AQ750LH is appropriate when X/Y work envelope needs are in the 700–750 mm range and 400 mm Z is sufficient — it is a smaller, lighter, and less expensive machine than the AG100L. If work regularly exceeds 750 mm in X or 500 mm in Y, the AG100L is necessary. Both machines share the same SP43A generator and linear motor architecture.
