Overview

The Matsuura MX-850 PC4 adds a 4-pallet changer to the largest machine in the MX trunnion-style 5-axis family, creating an automated production cell for mid-to-large 5-axis work. With an 850 mm (33.5 in) max workpiece diameter, BT50 spindle with 350 Nm of torque, and now 4 pallets cycling through the machine, the MX-850 PC4 handles automated production of parts that most compact 5-axis cells cannot touch — think structural aerospace components, large mold inserts, and heavy industrial precision parts.

Axis travel measures 900 x 660 x 600 mm (35.4 x 26.0 x 23.6 in) on X/Y/Z. The A-axis tilts from +20 to -110 degrees and the C-axis rotates a full 360 degrees. The standard spindle is a BT50 at 10,000 RPM with 22/30 kW (30/40 hp), giving the machine real cutting authority for aggressive roughing in steel, titanium, and Inconel. A 12,000 RPM BT40 option is available for aluminum-focused work. HSK-A63 and HSK-A100 spindle configurations are also offered.

Each pallet handles up to 400 kg (882 lb), reflecting the larger, heavier workpieces this machine is designed for. The tool magazine starts at 60 tools with options up to 120 positions. Tool-to-tool change time is 1.6 seconds. Pallet change time is approximately 30 seconds. The G-Tech 31i control with MIMS manages pallet scheduling and tool life across the cell.

The MX-850 PC4 weighs approximately 21,000 kg (46,297 lb) with a footprint of roughly 5,500 x 3,500 mm. CAMplete TruePath comes standard. This machine competes with the DMG Mori DMU 80 eVo with pallet automation, Hermle C 400 with HS flex heavy, and Mazak VARIAXIS i-800 with pallet changer. For shops running medium-to-large structural aerospace parts or mold components that require both 5-axis capability and unattended production, the MX-850 PC4 delivers BT50 cutting power with practical automation.

Strengths & Limitations

Strengths

BT50 spindle with 350 Nm torque delivers genuine heavy-cutting authority in steel, titanium, and Inconel across all 4 automated pallets
850 mm workpiece diameter and 400 kg per-pallet load handle mid-to-large aerospace and mold work that smaller cells cannot accommodate
4-pallet automation adds lights-out capability to the MX-850 without the cost and complexity of a full FMS system
RAM-type column design maintains the structural rigidity the MX-850 is known for, even under heavy automated production loads
Same G-Tech 31i control and MIMS cell management as the rest of the MX lineup for consistent operator experience
CAMplete TruePath standard provides critical crash protection during unattended operation of expensive large-format workpieces

Limitations

21,000 kg machine weight and 5.5 x 3.5 m footprint require substantial foundation work and significant floor space
Standard 10,000 RPM spindle speed is slower than some competitors offering 12,000-15,000 RPM in this size class
Price tag of $550K-$800K is a significant investment that requires consistent production volume across all 4 pallets
A-axis tilt range (+20° to -110°) is slightly more limited than the MX-520's +10° to -125°

Best For

Aerospace manufacturers producing structural components, engine housings, and landing gear parts that need automated 5-axis production Mold and die shops running large cavity inserts and core blocks through automated 5-axis finishing cycles overnight Heavy-industry precision shops machining large steel and titanium components that require both BT50 power and unattended capability Shops stepping up from the single-table MX-850 that need pallet automation without changing to a completely different machine platform Production environments running 2-4 different large part setups in rotation for maximum spindle utilization

Frequently Asked Questions

01 What does a Matsuura MX-850 PC4 cost?

New MX-850 PC4 pricing typically ranges from $550,000 to $800,000 depending on spindle type, tool magazine capacity, and options. This represents a $150K-$200K premium over the single-table MX-850 ($400,000-$600,000). Fully loaded with HSK-A100 spindle, 120-tool magazine, and through-spindle coolant, configurations can approach $900,000.

02 How does the MX-850 PC4 compare to the MAM72-63V?

The MAM72-63V offers up to 40 pallets and 520 tools for true FMS-level automation but maxes out at 630 mm workpiece diameter. The MX-850 PC4 handles larger parts (850 mm diameter) with more table load per pallet (400 vs 300 kg) but with only 4 pallets. Choose the MAM72-63V for high-mix, high-count automation on medium parts. Choose the MX-850 PC4 when part size exceeds what the MAM72 can handle.

03 Can the MX-850 PC4 run lights-out overnight?

Yes, with appropriate setup. Four pallets with cycle times of 30-120 minutes per pallet provide 2-8 hours of unattended operation. The limiting factors are tool life, coolant capacity, and chip evacuation rather than the machine itself. The MX-850's larger chip conveyor and coolant tank are sized for extended production runs.

04 What foundation requirements does the MX-850 PC4 have?

At 21,000 kg, the MX-850 PC4 requires a reinforced concrete foundation designed for the machine's static and dynamic loads. Matsuura provides detailed foundation drawings during the pre-installation phase. Most modern industrial buildings with standard 6-inch reinforced concrete floors can support the machine, but older facilities may need foundation upgrades. Plan for 3-4 weeks of foundation preparation before machine delivery.
