Frequently Asked Question

FAQS For the Servo Press Industry

What are the core advantages of your servo press over traditional presses?

Our gantry-type high-speed precision servo press (TNB-HO Series) features ultra-long axial bearings with zero clearance and preloaded bolt-extended guide rails, achieving dynamic and static precision exceeding super-grade standards, significantly extending mold lifespan. The servo-driven technology enables precise stroke speed control (2-800 spm), lower energy consumption, and a forced lubrication cooling system to ensure long-term stability and reduced consumable costs. Traditional presses lag behind in precision, energy efficiency, and maintenance costs.

How do you ensure long-term accuracy and rigidity of the machine?

The fuselage uses high-strength castings treated with internal stress elimination, combined with bolt-fastened frame structures preloaded with high-pressure oil to enhance rigidity. The guide posts employ zero-clearance ultra-long axial bearings, while preloaded bolts on extended guide rails ensure stable dynamic/static precision. The forced lubrication cooling system minimizes thermal deformation, further safeguarding accuracy.

Are maintenance costs high for servo presses? How often are consumables replaced?

Designed for low consumables, our presses reduce wear via a forced lubrication system and circulating cooling. Critical components like high-alloy steel crankshafts and saw-tooth sets undergo heat treatment and precision grinding for extended durability. Standard configurations include a lubricant circulation cooling system and an electric mold height adjuster (0.01mm precision), ensuring easy maintenance and lower lifetime costs than traditional presses.

Does the press support integration with automated peripheral equipment?

Yes! Our high-speed servo presses are compatible with optional devices like high-speed feeders, straighteners, and quick clamping systems (e.g., double-head feeding racks, hydraulic mold lifters). The high-sensitivity servo drive ensures precise positioning, enabling seamless automation for industries like automotive, electronics, and appliances requiring high-precision stamping.

How do you ensure safety and environmental compliance?

Safety features include an oil-pressure sliding block lock, front/rear safety doors, and fail-safe servo drives. Environmentally, the forced lubrication system minimizes oil waste, while dynamic balance design reduces noise/vibration, complying with international eco-standards.

What is the precision and flexibility of mold height adjustment?

The standard electric mold height adjuster offers 0.01mm display precision, supports 30 mold data presets, and batch control. All models (TNB45HQ to TNB660HQ) provide 50mm mold height adjustment, paired with a reversible handwheel for flexible, pinpoint accuracy.

What is the maximum material thickness and feeding line height range?

Feeding line heights range from 130mm to 240mm (±50mm), with maximum capacities up to 6600kN, suitable for high-strength alloys, copper, and aluminum. Worktable sizes span 750mm×550mm to 3200mm×1400mm, accommodating diverse stamping needs.

Do you offer custom configurations?

Absolutely! Beyond standard features (e.g., split control box, work lights), optional add-ons include a lower dead point detector, hydraulic shockproof feet, and quick mold-change systems. Technical specs (stroke, table size) can be tailored to meet unique production requirements.

What after-sales services do you provide?

We offer global technical support, installation guidance, and scheduled maintenance. Critical components (e.g., servo drives, high-alloy steel parts) come with extended warranties for worry-free operation.
