CNC Machines

Collection: CNC Machines

CNC machines are essential for job shops, manufacturers, and precision fabricators who need repeatability, speed, and accuracy beyond manual equipment. Pittsburgh Spray Equipment carries a focused selection of CNC mills, lathes, and routers—primarily Grizzly industrial-grade models—designed for shops ranging from small 2–3 person operations to larger production environments. CNC routers handle wood, composites, and soft metals; CNC mills and lathes deliver tight tolerances for metal and plastic work. Unlike general-purpose equipment, these machines require proper electrical infrastructure, operator training, and maintenance. Grizzly's CNC lineup balances affordability with rigidity and part availability, making these machines accessible for shops upgrading from manual equipment. Whether you're routing cabinet parts, turning precision shafts, or milling enclosures, the right CNC machine reduces labor costs, minimizes scrap, and frees operators for secondary tasks. Our selection emphasizes mid-range capacity and proven reliability—the sweet spot for most fabrication shops.

How to Choose the Right CNC Machines

Confirm three-phase or single-phase power availability; most industrial CNC mills and lathes require 480V or 220V three-phase.
Measure available floor space; CNC routers range from 24×36" to 4'×8', affecting layout and material handling.
Verify motor horsepower matches your primary material: 3–5 HP for wood/composites, 5–10 HP for aluminum, 10+ HP for steel.
Check spindle speed range (RPM) against your typical tooling; router spindles run 10,000–24,000 RPM; lathe spindles 50–2,000 RPM.
Assess table/chuck capacity and auto-tool changer availability if production volume justifies faster tool changes.
Review water-cooling requirements for spindles and the coolant system cost for mills and lathes used on ferrous metals.
Confirm lead time, delivery logistics, and on-site setup support—these machines often require professional installation and leveling.

Frequently Asked Questions

What motor horsepower do I need for routing hardwood and plywood?

A 3 HP spindle is standard for hardwood and plywood routing at typical feed rates and bit sizes. For continuous production, verify your spindle can sustain 3 HP continuously, not peak. Larger diameter bits (over 1") or harder woods (oak, maple) may benefit from 5+ HP to reduce bit deflection and chatter.

Do I need three-phase power for a CNC machine, or can I run it on single-phase?

Most industrial CNC mills and lathes require three-phase power (220V or 480V) for the main spindle motor and hydraulic pump. Many routers and smaller machines offer single-phase options at 220V. Check your electrical service before purchasing. Three-phase provides better efficiency and torque stability; single-phase limits motor size and increases heat.

How much space does a 4'×8' CNC router need on the shop floor?

Minimum 6'×10' clear floor space accounts for the machine footprint, material loading area, and operator access. Add another 2–3 feet on one side for pallet jacks and sheet material staging. Consider ceiling height for sheet stock and dust collection ducting. Plan for electrical panel and coolant tank proximity.

Should I buy a CNC lathe with an automatic tool changer?

An auto tool changer (like the Grizzly G0884) reduces operator intervention and cycle time on repeat jobs, justifying the cost if you run production batches. For one-off or low-volume work, manual tool changes are acceptable. Factor labor savings against machine cost; most shops see payback in 12–24 months of active production.

What's the difference between a CNC router with a T-slot table versus a vacuum table?

T-slot tables (like the G0931) accept clamps and fixtures for irregular or thin parts; they're flexible but require manual clamping setup. Vacuum tables hold flat sheet stock automatically, speeding changeovers on panel work. T-slot is more versatile for custom jobs; vacuum suits high-volume sheet production. Grizzly offers both; choose based on your typical workload.
