Overview

The Quaser MH800P is a horizontal machining center designed around an 800 mm pallet size, targeting mid-to-large production machining of prismatic parts in automotive, aerospace, heavy equipment, and general engineering applications. As one of the larger machines in Quaser's HMC lineup, the MH800P serves shops that have outgrown 630 mm pallet HMCs in workpiece envelope or weight capacity but are not yet requiring the scale of 1,000 mm class machines. Quaser's reputation for above-average geometric accuracy relative to price, well-established in the VMC segment, extends to the MH800P with the same rigorous factory calibration protocols applied across the product range.

Horizontal machining centers with a pallet changer deliver productivity advantages that vertical configurations cannot match: gravity-assisted chip evacuation from deep bores, bolt-hole circles, and cavity features; dual-pallet operation enabling setup of the next part during cutting of the current one; and B-axis indexing that allows four-face machining in a single clamping without 5-axis interpolation. The MH800P takes full advantage of these inherent HMC strengths with a high-torque, high-power spindle appropriate for heavy steel and cast iron cutting, deep coolant through the spindle, and a generous tool magazine serving complex, multi-operation prismatic parts.

The MH800P's spindle is typically configured with a BT 50 or HSK-A100 taper running to 6,000 or 8,000 RPM with a 37 kW motor, appropriate for heavy roughing of steel, cast iron, and aluminum at aggressive depths and feed rates. The B-axis rotary table indexes in 1-degree increments (0.001-degree optional) with a precision Hirth coupling that locks the pallet at each indexed position, providing the rigidity needed for heavy interrupted cuts. Pallet change time in the 15–20 second class maintains productivity in multi-operation sequences.

Quaser builds the MH800P on a symmetrically-thermally-compensated column and base structure, minimizing thermal displacement during extended production runs. Spindle thermal compensation using sensor arrays adjusts the Z-axis offset continuously, holding Z positioning accuracy within specification even as spindle and structure temperatures stabilize during warm-up and vary through the shift. This is particularly important in high-volume production where the first and last part of a shift must be dimensionally equivalent without operator intervention.

Pricing for the MH800P is estimated in the $650,000 to $850,000 range depending on control selection, pallet system configuration, tool magazine capacity, and through-spindle coolant specification. This positions the machine below Makino a81M and Okuma MA-800H equivalents while targeting buyers who prioritize geometric accuracy and value Quaser's calibration standards over the broader brand recognition of Japanese Tier 1 HMC manufacturers.

Strengths & Limitations

Strengths

800 mm pallet capacity and 1,500 kg workpiece weight rating handle large, heavy prismatic workpieces in automotive drivetrain, aerospace structural, and heavy equipment applications that exceed 630 mm HMC capability
37 kW / 590 Nm spindle provides the power and torque for aggressive roughing of steel and cast iron — a clear advantage over smaller HMCs that require lighter cuts and more passes to reach finished dimensions on large, tough workpieces
Quaser's documented factory calibration with laser interferometer and Renishaw ballbar testing ensures geometric accuracy is verified before shipment, differentiating the MH800P from lower-tier HMC manufacturers who rely on assembly precision alone
Dual-pallet configuration with 17-second pallet change minimizes non-cut time in production sequences, maintaining spindle utilization rates competitive with Japanese Tier 1 HMCs at a lower capital investment
Thermal compensation system on column and spindle reduces Z-axis drift during long production runs, maintaining dimensional consistency between first and last part of a shift without operator measurement and offset adjustment

Limitations

Quaser's HMC service network is considerably thinner than Makino, Okuma, or Mazak globally — buyers in markets without a strong Quaser distributor face longer service response times and parts sourcing challenges that can affect production availability
The 6,000–8,000 RPM spindle speed ceiling limits high-speed aluminum machining efficiency compared to HMCs with 12,000+ RPM spindles; shops with significant aluminum production should evaluate whether the higher spindle speed matters for their cycle times
$650K–$850K pricing requires a clear justification versus a Japanese Tier 1 HMC at similar price points — Quaser's accuracy credentials are strong but brand recognition and resale value favor the established Japanese builders in most markets

Best For

Automotive Tier 1 suppliers machining cylinder heads, transmission housings, steering knuckles, and other complex cast aluminum and cast iron prismatic parts requiring multi-face machining with consistent tolerances across high production volumes Aerospace manufacturers producing large aluminum structural brackets, bulkheads, and rib structures that require a combination of aggressive material removal and precision feature tolerances in a single-setup horizontal configuration Heavy equipment and construction machinery manufacturers machining large hydraulic manifolds, gear housings, and structural castings where workpiece weight and size exceed what 630 mm class HMCs can accommodate Job shops seeking a precision-grade HMC for high-mix, high-complexity prismatic work where Quaser's calibration standards provide an accuracy advantage over general-grade Taiwanese HMCs at a cost advantage over equivalent Japanese machines

Frequently Asked Questions

01 How does the Quaser MH800P compare to the MH630P?

The MH630P uses a 630 mm pallet and is suited for medium-sized prismatic parts. The MH800P scales up to an 800 mm pallet with a proportionally larger work envelope, higher workpiece weight capacity (1,500 kg versus approximately 800 kg on the MH630P), and a more powerful spindle appropriate for heavier cutting. The MH800P is the right choice when parts regularly approach or exceed 630 mm in any dimension, or when workpiece weights exceed the MH630P's payload. The MH800P's larger footprint and higher price require a clear part size or throughput justification.

02 What is the B-axis indexing resolution on the MH800P?

Standard B-axis indexing is 1-degree increments using a precision Hirth coupling that provides rigid, repeatable positioning at each index angle. For applications requiring finer angular resolution — typically compound angle features or precise angular datum relationships — 0.001-degree B-axis positioning is available as an option, typically requiring a different rotary drive system and control configuration. The vast majority of prismatic HMC work uses 90-degree or 1-degree indexing, making the 0.001-degree option relevant mainly for specialized aerospace and precision engineering applications.

03 Can the MH800P be integrated into an FMS (Flexible Manufacturing System)?

Yes. The MH800P's dual-pallet configuration is the foundation for FMS integration, and Quaser supports connection to external pallet pool systems and FMS controllers through standard interface protocols. For larger FMS installations involving multiple machines and centralized pallet storage and transport, Quaser works with system integrators who handle the FMS architecture, pallet handling equipment, and central control system. The machine's Fanuc 31i-B5 or Siemens 840D sl controls support the DNC communications and automatic tool management interfaces that FMS coordination requires.

04 What through-spindle coolant pressure does the MH800P support?

The MH800P comes standard with a 70 bar through-spindle coolant system. 70 bar is the working range for effective chip evacuation in deep-bore and deep-pocket machining in steel and cast iron — the primary application area for an 800 mm class HMC. Higher pressure options (up to 100 bar) are available for particularly challenging deep-hole drilling applications. The spindle seal design on both BT 50 and HSK-A100 taper configurations supports full 70 bar pressure without compromising spindle bearing life under normal production conditions.

05 Is the Quaser MH800P available with a Siemens control?

Yes. Siemens Sinumerik 840D sl is available as an alternative to the standard Fanuc 31i-B5. The Siemens option is typically chosen by shops in European markets where Siemens controls dominate the installed base, or by manufacturers whose CAM and DNC infrastructure is Siemens-centric. Both control options support full 5-axis interpolation if needed. Quaser provides full machine-specific cycles and canned routines for both control platforms. Lead times for the Siemens option may differ from the standard Fanuc configuration depending on regional availability.
