DD703.50 CNC Drilling Machine

Key specs: spindle speed range 20–130 r.p.m (see note below), drilling speed 30–60 mm/min, motor power 3 kW, machine weight ~2500 kg, worktable 700 × 1000 mm, X-Y travel 500 × 630 mm, spindle servo stroke 600 mm, electrode clamping diameter 0.3–3.0 mm, maximum distance between head (director) and table 500 mm. Dimensions (DD703.50): 2000 × 1500 × 1900 mm.

The product description lists a variable spindle speed from 20 to 130 r.p.m. Note: the detailed spec table lists 20–120 r.p.m for both models. Please confirm the exact delivered spindle-speed range with your supplier if precise upper-end RPM is critical for your application.

The drilling speed (feed) range is 30–60 mm/min, suitable for controlled, precision drilling across a variety of materials.

It clamps electrode wires with diameters from 0.3 mm up to 3.0 mm, covering a wide range of small-diameter tooling and electrode applications.

Main differences: X-Y travel (DD703.30: 300 × 400 mm; DD703.50: 500 × 630 mm), workbench size (DD703.30: 260 × 380 mm; DD703.50: 700 × 1000 mm), spindle servo travel (DD703.30: 300 mm; DD703.50: 600 mm), spindle head travel (DD703.30: 200 mm; DD703.50: 500 mm), and overall dimensions (DD703.30: 1260 × 1160 × 1900 mm; DD703.50: 2000 × 1500 × 1900 mm). Choose DD703.50 for larger workpieces and greater travel.

The DD703.50 is designed for a wide range of materials including common metals, plastics and composite materials used in precision drilling. Material-specific performance depends on tooling, electrode type, feed/speed settings and coolant; consult the vendor for recommendations for very hard or exotic materials.

The machine’s input power is 3 kW. Exact electrical requirements (voltage, phase, breaker size) depend on the configuration and your region—confirm with the supplier or your electrician for proper supply and circuit protection.

The DD703.50 weighs approximately 2500 kg. Its nominal dimensions are 2000 × 1500 × 1900 mm. Ensure your floor/load-bearing structure can support this weight and that you have sufficient space for access and maintenance.

The DD703.50 is equipped with CNC control for precise drilling. Controller type and software compatibility can vary by configuration—many units support standard G-code or vendor-specific control software. Confirm the exact controller model and file/communication formats with the supplier if you require specific CAM/CNC integration.

The machine should be placed on a level, stable floor capable of supporting its weight. Some installations may require anchoring or a reinforced foundation to minimize vibration. Professional installation and alignment by authorized technicians is recommended.

Routine maintenance typically includes regular cleaning of chips/contaminants, lubrication of guides and moving parts, inspection and tightening of fixtures, periodic spindle checks and calibration, and replacement of worn consumables (electrodes, clamps, seals). Follow the vendor’s maintenance schedule for intervals and procedures.

Spare parts and after-sales service availability depend on your supplier and region. Ask your vendor about local stocking of critical spares, recommended spare parts list, service contracts and authorized service providers before purchase.

Typical safety features include emergency stop, guarded moving parts, electrical protection and interlocks. Operators should receive training on safe operation, PPE use, machine controls and emergency procedures. Confirm with the supplier what safety equipment and training are included or available as add-ons.

The 700 × 1000 mm worktable and 500 × 630 mm X-Y travel allow handling of relatively large workpieces within those travel limits. Workpiece fixturing is application-dependent—use appropriate clamps, fixtures or vacuum tooling rated for precision drilling; consult the supplier for recommended fixturing solutions for your parts.
