General Vertical Machining Center

A shop that machines molds in the morning and automotive brackets in the afternoon needs one machine that can handle both. This general purpose vertical machining center fills that role. X travel 800 mm, Y 550 mm, Z 700 mm. Table 1260×550 mm, load 600 kg. Three spindle options: belt 10k, direct 12k, or motor 15k rpm. Taper BT40 (HSK‑A63 optional).

Scope of Application

Job shops and automated cells. Boxes, plates, housings, irregular shapes. High‑mix, high‑volume milling, tapping, 3D contouring.

Equipment Manufacturing Process

The customer is responsible for preparing a foundation (a 300mm minimum concrete slab without steel reinforcement, away from vibration/temperature changes) and providing 380V three-phase power and clean, dry compressed air (filtered to 100 microns). Upon delivery, a joint inspection is performed. The customer handles rough leveling, after which our engineers arrive for fine-tuning, full Renishaw laser calibration, and a one-day on-site operator training.

About Us

Hodao CNC Technology manufactures vertical machining centers, high-speed gantry machining centers, large-stroke gantry machining centers, high-speed drilling and tapping machines, horizontal machining centers, and engraving milling machines. Products are widely used in precision mold manufacturing, automotive parts, precision part processing, and aerospace. Every machine undergoes 72‑hour continuous operation test before delivery. Warranty period is 12 months with lifetime maintenance support.

FAQ

Q1. What advantage does the torque tube column design provide during heavy cutting operations?

A: The torque tube column is a key structural feature of the HD-VF857. Unlike a standard open-section column, the torque tube design creates a closed, box-like structure that resists both bending and torsional forces. During heavy cutting, this means less deflection at the spindle nose, which directly translates to better surface finish and longer tool life. The torque tube works together with the rib-reinforced bed and the six-slider Z-axis configuration to transfer cutting vibrations away from the cutting zone and into non-critical areas of the machine base. For customers machining steel, cast iron, or hard alloys, this added rigidity allows for more aggressive depth of cut without sacrificing accuracy.

Q2. How long is the warranty and what does it cover?

A: Twelve months from the machine arrival date. Free repair covers manufacturing defects. User‑caused damage from crashes, improper use, or unauthorized modification requires paid repair. After the warranty expires, service continues with spare parts and labor charges. Lifetime maintenance support is available. Ownership remains with us until full payment is cleared.

Q3. What spindle speed choices exist?

A: Three configurations: belt drive at 10,000 rpm for general purpose, direct drive at 12,000 rpm for higher speed, or motor spindle at 15,000 rpm for high‑speed finishing. All use BT40 taper with optional HSK‑A63. Torque output is 96 Newton meters for both FANUC and Mitsubishi drive systems.
