Starting a CNC Workshop: Machine Selection, Power Requirements, Floor Space and Costs
Complete startup guide for establishing a CNC machine shop: choosing your first VMC and lathe, 3-phase power, foundation vibration isolation, tooling packages, and factory sourcing.
The Direct Engineering Answer
Starting a profitable precision CNC workshop requires three fundamental investments: the core machining assets (a versatile 3-axis Vertical Machining Center such as the IX-VMC-1060 combined with a heavy-duty CNC turning lathe like the IX-LAT-500), factory utility infrastructure (clean 3-phase electrical power with voltage stabilization, an 8–10 bar screw compressor with refrigerant air dryer, and a reinforced 200mm concrete slab floor), and initial tooling packages (BT40 toolholders, collet sets, carbide end mills, turning inserts, and precision measuring instruments). An initial investment of $65,000 to $115,000 USD direct from Turkish manufacturing covers high-specification machinery with Japanese or German control systems.
Understanding the Buyer's Situation
Entrepreneurs, toolmakers, and engineers transitioning into independent manufacturing frequently struggle with machinery selection. Buying cheap lightweight hobbyist machines results in chatter marks and inability to machine steel, while buying brand-new Japanese or Swiss luxury machines incurs crushing debt. IXORTA CNC machines made in Turkey provide heavy cast-iron Meehanite damping, roller linear guideways, and industrial Fanuc/Siemens controllers at factory-direct pricing.

A common pitfall is purchasing either only a milling center or only a turning lathe, forcing the shop to turn away half of incoming customer job requests. The optimal starter configuration consists of: 1. Vertical Machining Center (IXORTA IX-VMC-1060): 1000 × 600 × 600 mm XYZ travel, BT40 / 10,000 RPM direct-drive spindle, 24-tool arm-type automatic tool changer (ATC). Capable of precision 3-axis prismatic milling, mold cavity sinking, tapping, and hole drilling in aluminum, cast iron, and alloy steels. 2. CNC Turning Lathe (IXORTA IX-LAT-500): 500mm swing over bed, 750mm maximum turning length, 8-station hydraulic turret, and 8-inch hydraulic chuck. Handles cylindrical shafts, bushings, flanges, and threaded components.
Factory Floor Space, Foundation and Electrical Utilities
A small commercial machine shop requires: - Floor Area: 150 to 250 m² with at least 4.0m clear ceiling height and a wide roll-up access door (minimum 3.0m width) for forklift machinery delivery. - Vibration-Isolated Concrete Slab: Minimum 200mm thickness of C25/30 reinforced concrete. Precision machines must be leveled with heavy anchor bolts and anti-vibration leveling pads to prevent vibration transfer from neighboring stamping presses or forklifts. - Electrical Supply: 3-phase 380V / 50–60Hz supply. The connected load for a 2-machine cell plus compressor is approximately 45–55 kVA. An automatic servo-motor voltage stabilizer is mandatory to protect sensitive CNC control boards from grid voltage spikes.

| Rotary Screw Air Compressor | 10 HP (7.5 kW) with 500L tank & refrigerant dryer | 7.5 kW | $3,800 – $5,200 |
| Initial Tooling Package | BT40 toolholders, ER collets, carbide cutters, boring bars | N/A | $4,500 – $7,000 |
| Precision Metrology Kit | Mitutoyo digital calipers, micrometers, dial indicators, height gauge | N/A | $2,200 – $3,500 |
| Voltage Stabilizer (Servo) | 60 kVA 3-Phase Automatic Voltage Regulator | Passive | $2,400 – $3,200 |
| CAD/CAM Software & PC | 3-Axis CAM workstation license + industrial PC | N/A | $3,500 – $6,000 |
Compressed Air Requirement Calculation for a 2-Machine Cell
Engineering Assumptions: 1 × VMC (spindle taper air curtain + tool change air blast) + 1 × Lathe (chuck blow + part ejector).
- VMC spindle taper blast during tool change: ~450 L/min for 3 seconds per cycle.
- VMC positive pressure spindle labyrinth seal (continuous air curtain preventing coolant ingress): ~150 L/min continuous.
- CNC Lathe pneumatic/hydraulic chuck clean blast: ~200 L/min intermittent.
- Total continuous base air demand = 150 L/min + (450 × 0.20) + (200 × 0.15) = 270 L/min free air delivery (FAD).
- Safety factor (1.4× for hose leaks and line drops): 270 × 1.4 = 378 L/min (~0.38 m³/min) at 8.0 bar pressure.
- Compressor selection: A 7.5 kW (10 HP) rotary screw compressor delivering ~1,000 L/min with an integrated refrigerant dryer ensuring pressure dew point of +3°C to prevent water condensation inside pneumatic solenoid valves.
⚠️ Critical Buyer Mistakes to Avoid
- Operating without a refrigerated compressed air dryer — moist air causes water to enter pneumatic tool-change cylinders and corrodes expensive spindle bearings.
- Pouring machines on thin unreinforced concrete slabs, leading to bed twisting and inability to hold 0.01mm tolerances over a 500mm length.
- Neglecting to purchase chip conveyors, resulting in hours of manual chip shoveling and lost machining spindle hours.
Frequently Asked Questions
Which CNC controller is best for a beginner workshop: Fanuc, Siemens, or Syntec?
For commercial job-shop work, Fanuc 0i-MF Plus is the global standard because almost every CNC machinist already knows G-code programming on Fanuc. Siemens 828D with ShopMill is preferred for complex conversational programming without a CAM workstation, while Syntec offers the most cost-effective solution with excellent 3D surfacing performance.
Can IXORTA provide turnkey tooling and machine commissioning?
Yes. IXORTA supplies complete turnkey tooling packages (chucks, vises, toolholders, cutting inserts) and dispatches factory commissioning engineers to level the machines, verify geometric tolerances with Renishaw ballbars, and run test-part cutting.
