Where standard saws struggle with uncalibrated slabs and width limitations, the MSA eliminates both problems — face-down cutting geometry ensures flawless miters regardless of slab thickness variation, and the open worktable design imposes no width restriction on the material being processed.Linear guides with recirculating ball slides, automatic lubrication, and motorized variable-speed head travel give you the kind of repeatable precision that high-end countertop and cladding work demands. The heavy-duty hot-dip galvanized steel frame is built for continuous production use, not occasional shop cuts.Key Features & BenefitsFace-Down Cutting for Perfect 45° MitersProcessing slabs face-down eliminates the surface variation that causes miter angle errors on uncalibrated material — the reference surface is always consistent, so the miter is always accurate.No Slab Width LimitationThe open worktable design handles slabs of any width. No re-positioning, no width-based constraints on what you can run through the machine.Linear Guides with Recirculating Ball SlidesPrecision linear motion system delivers smooth, accurate head travel with minimal play — critical for consistent miter angles across long cuts.Motorized Variable Speed Head TravelBlade speed adjustable from 800 to 3400 RPM. Dial in the right speed for the material — slower for hard granite and quartzite, faster for ceramic and sintered panels.10 Pneumatic Pistons + 3 Slab StopsSecure slab positioning without manual clamping. Pneumatic pop-up stops handle thin ceramic and sintered materials safely.Hot-Dip Galvanized Steel FrameCorrosion-resistant construction built for wet shop environments. Removable splash guards along the full worktable length keep the machine clean and accessible.Technical Specifications Specification Detail X-Axis Travel 3300 / 3700 mm Blade Diameter 350–450 mm (14"–18") Max Material Thickness 0–80 mm Motor Power 5.5 kW (7.5 HP), 3-phase Variable Speed 800–3400 RPM Voltage 230V / 400V, 50/60 Hz Slab Positioning 10 pneumatic pistons, 3 slab stops Frame Heavy-duty steel, hot-dip galvanized SKU MQMSA19L-AHH Brand Achilli Available Configurations MSA 3700 – 3 Phase (7.5 HP, Variable Speed) — full production configuration with motorized variable speed head Side Extension Table (PVC Rollers) — expands working area for larger slab handling and positioning Compatible Materials Granite Marble Quartz and engineered stone Ceramic and large-format porcelain panels Sintered stone (Dekton, Neolith, etc.) Natural stone slabs up to 80 mm thick Common Applications 45° miter cuts for seamless countertop edges Waterfall island edges and book-matched miters Cladding and wall panel miter joints High-end kitchen and bathroom countertop fabrication Large-format sintered and ceramic panel processing Ideal For Stone fabrication shops specializing in high-end countertop work Fabricators running waterfall edges and book-matched miters Shops processing ceramic and sintered panels at production volume Operations requiring repeatable 45° accuracy across uncalibrated slabs Frequently Asked QuestionsWhy does the MSA cut face-down?Face-down cutting uses the finished face of the slab as the reference surface, eliminating thickness variation errors that cause miter angle inconsistency on uncalibrated material. The result is a consistently accurate 45° miter regardless of slab calibration.Is there a width limit on slabs the MSA can process?No. The open worktable design imposes no width restriction — you can run full-width slabs without re-positioning.What blade sizes does the MSA accept?350 mm to 450 mm (14" to 18") diameter blades.What power supply does the MSA require?The MSA 3700 runs on 3-phase power at 230V or 400V, 50/60 Hz. Confirm your shop's electrical supply before ordering.Can it handle sintered stone and large-format ceramic panels?Yes. Pneumatic pop-up slab stops are specifically designed for safe handling of thin ceramic and sintered materials.What optional accessories are available?Side extension table with PVC rollers, pop-up hydraulic rollers for slab loading, and an integrated water tank recycling system for blade cooling.More from Achilli Achilli ProEdge Portable Router — portable edge profiling router for countertop finishing Achilli AFR-A Motorized Bridge Saw — motorized bridge saw for precision slab cutting Achilli TOP Manual Working Center — manual working center for countertop fabrication Achilli TSA Portable Track Saw — portable track saw for on-site slab cutting Achilli SC500 Slab Cart — slab transport and handling cart Further Reading How to Cut Perfect 45° Miters on Stone: A Professional Guide Achilli Bridge Saw Buyer's Guide: AFR-A vs MSA — Which Saw is Right for Your Shop?
