ZH-600T CNC Drilling and Tapping Center

Product Overview

The ZH-600T CNC Drilling and Tapping Center is engineered for high-efficiency drilling, tapping, spot-facing, light milling, and multi-step hole machining. With its compact machining range, 20,000 rpm direct-drive spindle, fast axis movement, and automatic tool-changing system, the machine is well suited to batch production of small and medium-sized precision components.

Its working travels of 600 × 400 × 300 mm provide sufficient capacity for electronic housings, aluminum plates, heat sinks, automotive brackets, fixtures, communication components, precision hardware, and appliance parts. Multiple operations can be completed in one controlled setup, reducing manual transfers and the positioning errors that often occur when parts move between separate machines.

The fully enclosed structure also keeps coolant and chips inside the machining area. This creates a cleaner workshop environment while improving process visibility and operator protection.

Designed for Faster Batch Production

Hole-intensive components can become a production bottleneck when they require repeated clamping, manual alignment, or frequent tool replacement. The ZH-600T addresses these problems through coordinated CNC movement, rapid tool changing, and stable workholding.

All three axes reach a rapid traverse speed of 48 m/min, helping shorten non-cutting movement between holes and machining positions. The cutting feed range of 1–10,000 mm/min allows the process to be adjusted for different materials, cutting tools, and feature requirements.

A 21-tool arm-type magazine supports automatic tool changes in approximately 1.8 seconds. Drills, taps, chamfering tools, and milling cutters can therefore be arranged within the same program. This makes the machine especially practical for repeat orders where a few seconds saved on each cycle can produce a meaningful gain across an entire shift.

High-Speed BT30 Direct-Drive Spindle

As a High Speed BT30 Drilling Tapping Center, the ZH-600T uses a direct-drive spindle powered by a 5.5 kW motor. Its maximum spindle speed reaches 20,000 rpm, while a 15,000 rpm configuration is available for production requirements that do not require the higher speed.

The direct-drive structure delivers responsive acceleration and stable spindle operation. It is particularly effective when machining aluminum parts with dense hole patterns, small tapped threads, pockets, and milled surfaces.

Compared with a heavier general-purpose machining center, the BT30 configuration is focused on agility. Faster spindle response and shorter tool-change time allow the machine to handle repetitive drilling and tapping work without unnecessary idle time.

Working Range and Table Capacity

The machine is equipped with a 700 × 420 mm worktable and three T-slots for mounting vises, standard fixtures, or customized workholding systems. Its maximum table load is 250 kg, while the recommended workpiece capacity is approximately 600 × 400 × 300 mm.

Main Technical Specifications

Machining Accuracy and Repeatability

The ZH-600T provides a positioning accuracy of ±0.005 mm per 300 mm and repeatability of ±0.003 mm per 300 mm. This supports consistent hole spacing, thread position, pocket dimensions, and machined profiles throughout continuous batch production.

Machine accuracy can be checked with a laser interferometer. Pre-acceptance trial cutting can also be arranged after assembly and commissioning at the supplier’s facility. Once the machine has been delivered, installed, and commissioned, final acceptance cutting can be performed using the agreed workpiece and inspection criteria.

This validation process gives buyers a clearer basis for evaluating the machine than relying only on catalog parameters.

Mitsubishi M80VB CNC Controller

The standard ZH-600T configuration uses a MITSUBISHI M80VB CNC controller. The system supports high-speed drilling, rigid tapping, milling programs, tool management, and automated production cycles.

Other controller options, including FANUC, Mitsubishi, and Siemens configurations, can be discussed according to the project. The most suitable control system usually depends on operator experience, programming preferences, local technical support, and compatibility with the buyer’s existing equipment.

Optional Fourth-Axis Machining

A fourth-axis interface is included as standard. An indexer or rotary table can be added when the workpiece requires side drilling, tapping, or milling.

For parts with features on several faces, the fourth axis can reduce manual repositioning and allow more operations to be completed in one clamping. This saves handling time and helps control the accumulated positioning error that can occur after repeated setups.

Materials Suitable for Machining

The ZH-600T can process several commonly used industrial metals, including:

• Aluminum alloys
• Copper alloys
• Carbon steel
• Low-carbon alloy steel
• Light metal structural materials

It is particularly suitable as a CNC Drilling Tapping Machine for Aluminum Parts. Typical aluminum applications include 3C mid-frames, electronic housings, valve bodies, heat sinks, communication components, aluminum plates, and small automotive brackets.

The final cutting performance will depend on the selected tooling, fixture rigidity, spindle speed, feed rate, coolant method, and workpiece geometry.

Typical Application Industries

The ZH-600T is suitable for production in industries such as:

• 3C electronics
• Automotive components
• Communication equipment
• Precision hardware
• Home appliances
• General machinery
• Automation equipment
• Fixtures and jigs
• Precision molds
• Aluminum component manufacturing

The machine is especially useful for components requiring numerous holes, threaded features, small pockets, milled surfaces, or several tools within one production cycle.

Automotive Aluminum Valve Body Application

In one published application, the workpiece was an ADC12 aluminum automotive valve body measuring 350 × 250 × 120 mm. The original machining process required approximately 15 minutes per component and suffered from frequent tool-change delays and inconsistent surface quality.

The ZH-600T solution combined a 20,000 rpm direct-drive spindle, 21-tool arm-type magazine, 1.8-second tool changing, and 48 m/min rapid traverse. According to the application data, the machining cycle was reduced to under eight minutes. Tool-change waiting time decreased by 70%, surface roughness stabilized at Ra 1.6, and the production yield increased from 92% to 98.5%.

Actual results may vary according to tools, fixtures, programs, materials, and workshop conditions.

3C Aluminum Mid-Frame Application

Another application involved a 6063 aluminum mid-frame measuring 280 × 160 × 12 mm. The component required drilling, tapping, and side milling. The previous production process experienced thin-wall chatter, multiple setups, and limited daily output.

Using the ZH-600T, the manufacturer consolidated the required operations into one controlled machining process. Fourth-axis capability supported multi-face machining, while the three-axis drive system provided stable cutting movement.

Based on the published case information, daily production increased from 180 to 320 pieces. The previous chatter marks were also eliminated under the validated machining conditions.

Enclosure, Coolant and Chip Removal

The machine uses a fully enclosed floor-standing cabinet with front access doors and viewing windows. Operators can monitor the process while coolant and metal chips remain contained within the work area.

A chain-type chip conveyor and chip cart support continuous chip removal during batch production. The standard coolant arrangement includes flood coolant and a coolant tank. Spindle center through-coolant is available as an option for applications requiring improved cooling and chip evacuation near the cutting edge.

Optional systems include:

• Fourth-axis indexer or rotary table
• Renishaw or Marposs probe
• Spindle center through-coolant
• Oil mist collector
• Automatic lubrication system
• Custom machining fixture
• Alternative CNC controller
• Customized coolant configuration

Installation and Working Environment

The ZH-600T weighs approximately 4,000 kg and has overall dimensions of 1850 × 2650 × 2650 mm. It should be installed on a stable foundation with correct machine leveling.

The workshop should also provide:

• A reliable power supply
• Clean compressed air
• Adequate ventilation
• Coolant management
• Sufficient maintenance clearance
• Regular lubrication
• Stable ambient temperature for high-precision production

A temperature-controlled workshop is recommended when the workpieces have demanding dimensional tolerances.

Customization and Trial Cutting

Machine selection should be based on the actual part rather than spindle speed alone. Workpiece size, material, hole diameter, thread specification, tolerance, surface finish, fixture design, and expected output all influence the final configuration.

Zhihe CNC can provide custom fixture support and trial cutting according to the buyer’s drawings. To receive an accurate machine recommendation and quotation, buyers should provide:

• 2D or 3D part drawings
• Workpiece material
• Part dimensions
• Hole and thread specifications
• Required tolerances
• Surface finish requirements
• Expected daily or monthly output
• Preferred CNC controller
• Fixture and automation requirements

Based on this information, the technical team can determine whether the standard ZH-600T is suitable or whether a fourth axis, probe, through-spindle coolant, or customized fixture is required.

Packaging, Delivery and After-Sales Service

The estimated production lead time is approximately 45–60 working days after receipt of the down payment and signed contract, subject to the final agreement.

For overseas shipment, the machine is packed in a standard export wooden case with moisture-resistant, shock-resistant, and rust-prevention treatment. Sea or air delivery can be arranged under commonly used terms such as FOB or CIF.

Installation and commissioning support are available. The supplier can also provide two to three days of on-site training covering machine operation, basic programming, routine maintenance, and troubleshooting.
