Machine Introduction

General Description

• This machine tool is a crossbeam mobile high-speed machine with a fixed worktable.
• It mainly consists of a bed, crossbeam, crossbeam slide, slider, chip removal device, lubrication system, cooling system, electrical control cabinet, and CNC system;
• Machine bed (including worktable), left and right guide rail seats, crossbeam, Z-direction slide table, etc.: Made of high-quality resin sand cast iron, subjected to secondary aging treatment of thermal aging and vibration aging, scientifically and accurately removes stress.
• The structure is optimized using finite element analysis method to achieve maximum rigidity and best stability, especially with the use of arch bridge structure for the crossbeam, which effectively suppresses sagging.
• It is particularly suitable for high-precision and high smoothness machining of molds and high-speed machining of non-ferrous metals.
• Compared with worktable mobile machine tools that carry heavy workpieces, it avoids those defects such as slower movement speed, lower efficiency, and greater damage to the machine tool.

Highlights

Worktable

• The workbench is an integral structure and does not move during the machining process of the machine tool. Made by resin sand casting and subjected to two aging treatments to eliminate internal stress.
• The workbench is 1900mm long and 1300mm wide. It's is a box shaped structure with reinforced ribs inside.
• The top surface of the workbench has a T-shaped groove with a width of 22mm, and the reference T-shaped groove width is 22H7
  

Crossbeam

On the crossbeam, a rectangular guide rail is added on the basis of the original two linear guides installed perpendicular to each other, which extends the cutting resistance torque and bearing area, greatly increasing the cutting resistance and effectively overcoming the common weakness of gantry machine tools and large vertical cutting point cantilevers being too long.

 

Crossbeam slide and ram

• The shape of the crossbeam slides is in the shape of a "7". There are six sliding blocks connected to the guide rails between the crossbeam sliding plate and the crossbeam. The guide rails are vertically distributed with 35mm and 55mm line rails and supported by one auxiliary rectangular guide rail.
• The guide rail between the crossbeam slider and the ram adopts four 45mm roller guides, which have excellent rigidity and stability. Ensure high cutting volume, fast speed, high precision, and super rigidity, especially suitable for processing large quantities of products and high-precision molds.
• The vertical movement of the slider is equipped with a non energy consuming pneumatic-hydraulic counter balance device to eliminate the stretching deformation of the ball screw caused by the weight of the slider, ensuring the accuracy of the feed displacement. The hydraulic balance device is equipped with an oil filling and pressure maintaining system to achieve automatic monitoring and oil replenishment. It can ensure long-term stability of balanced pressure, and its energy reserve is achieved by an accumulator.

 

Spindle

• Adopting the German INNA high-precision high-speed electric spindle, which has high dynamic balance, high precision, and strong stability, ensuring smooth high-speed rotation and high smoothness processing.
• Electric spindle power torque: 22kw/29.2Nm, maximum torque 41Nm

Pneumatic & lubrication system

• SMC pneumatic components with reliable quality and easy installation and adjustment;
• The lubricating oil circuit is carefully designed, and the automatic lubrication system checks the lubricating oil during machine operation and applies oil to the guide rail and ball screw.
• All key components can be lubricated with the correct amount of lubricating oil. Our automatic lubrication system not only saves time, but also reduces maintenance troubles, ensuring that the machine tool runs smoothly all year round.

Stable protective system

• The X-axis guide rail adopts a high-speed stainless steel protective cover, which effectively prevents iron filings from damaging the screw and guide rail.
• It is professionally designed, beautiful, reasonable, and safe.
• The Y-axis adopts a leather tiger organ style shield, which is wear-resistant and corrosion-resistant.

Control System

Siemens, Fanuc, Mitsubishi and Huazhong systems are available for option;

 

Machine Applications

Ensure high cutting volume, fast speed, high precision, and super rigidity, especially suitable for processing large quantities of products and high-precision molds.

It is particularly suitable for high-precision and high smoothness machining of molds and high-speed machining of non-ferrous metals.

 

Machine Features

• Compact one-piece structure of the machine guide rail base and worktable brings large loading capacity and stable structure.
• Less footprint obtained, only 60% of the table moving type;
• Fixed worktable for big loading capacity, suitable for processing extra large workpiece;
• Long-term use of accuracy retention and better stability can be kept for all moving parts keep weight unchanged;
• Constant weight of moving parts ensures the machining contour accuracy and no machining overcutting;
• The movement of Longmen (X-axis) adopts internationally advanced ultra precision dual drive synchronization technology, with high synchronization of the position ring, speed ring, and current ring servo rings, solving the problem of slight oscillation when the load difference on both sides is synchronized by the position ring alone.
• It achieves smooth driving of large-span moving parts, precise positioning.
• Been applied in nearly a thousand units for more than ten years, with leading technology and stable application.
