After an in-depth discussion of the core parameters and configuration of the HOWFIT gantry 400-ton high-speed punch press DDH-400T-ZW-3700, it is worth emphasizing its main features. These features not only highlight the pursuit of technological innovation by Haohui Gaojiang Precision Machinery, It also directly affects the operating efficiency, product quality and maintenance costs of the equipment. Here is a further analysis of these characteristics:

### 1. Extra wide workbench

It has a workbench area with a maximum width of 3700mm, which allows the equipment to easily cope with more complex and diverse processing technology requirements. The extra-wide workbench not only provides the possibility for processing large materials, but also greatly improves flexibility and production efficiency.

### 2. Stable bottom dead center repeatability

Stable bottom dead center repeatability not only reduces mold wear and ensures product accuracy, but also effectively reduces bottom dead center runout. This not only extends the service life of the mold, but also ensures the consistency of product quality during long-term production processes, providing a reliable guarantee for processing with high-precision requirements.

### 3. Minimize thermal displacement

The thermal control technology mastered in the field of small high-speed punch presses is used to suppress thermal displacement during equipment operation to the greatest extent, thus improving the accuracy of product processing. The application of this technology is a reflection of HOWFIT's continuous technological innovation and refined management concepts, ensuring stable machine performance and accurate product dimensions under continuous high-speed operating conditions.

### 4. High-precision 8-sided slider guide

This equipment adopts 8-sided needle roller slider guide rail, which not only has ultra-high load-bearing capacity, but also the long guide rail design makes it better able to withstand eccentric loads. This design not only ensures high-precision operation of the equipment, but also makes subsequent maintenance more convenient, reduces maintenance costs, and increases the service life of the equipment.

Based on these characteristics, HOWFIT gantry 400-ton high-speed punch press DDH-400T-ZW-3700 is undoubtedly an excellent equipment on the market with high performance, high precision and easy maintenance. Through innovative design and exquisite craftsmanship, it meets the dual needs of high efficiency and high-quality production, and provides powerful production solutions for the majority of manufacturing companies.
