Compact Horizontal Machining Center

1

High Rigidity & Long‑term Precision

The base, worktable, column, crossbeam, slide seat and ram are all made of high-quality resin sand molding and high-strength high-quality cast iron. They undergo a complete heat treatment process to eliminate residual stress and are equipped with sufficient reinforcing ribs to ensure that the entire machine has sufficient strength, rigidity and high stability.

All the main mechanical castings are made of high-rigidity cast iron to ensure the best structural stability. The column, base and saddle are of box structure. Combined with a reasonable reinforcement design of the tendons and bones, it not only enhances the structural rigidity but also minimizes thermal deformation.

The characteristics of the X and Y axis guide rails: The axis guide rail pair adopts two heavy-duty linear guide rails, which have a small friction coefficient and high sensitivity. It has low vibration at high speed and no crawling at low speed. The positioning accuracy of the drive shaft is high, and the servo drive performance is excellent. At the same time, it has a large load-bearing capacity and good anti-vibration performance during cutting, which can improve the dynamic characteristics of the machine tool, enhance the precision stability and service life of the machine tool. The shaft crossbeam guide rail adopts two heavy-duty linear guide rails. The guide rails are arranged in a stepped manner, with a large span and sufficient bending stiffness and torsional stiffness.

stand column

The columns adopt symmetrical and excellent balance design, demonstrating unique processing accuracy.

3

ball screw

The three-axis ball screw is pre-tensioned to effectively suppress the problem of thermal deformation.

4

Optional tool magazine (specify when customizing)

The structures of tool magazines include row tool type, bucket type, disc type and chain type tool magazines.

5

Spindle cooling device

A side spray cooling device is installed on the side of the main shaft. It features a dual-purpose design for water flushing and air flushing, which can quickly remove the heat from the tool and workpiece, effectively improving the processing accuracy. It can be programmed for switch control.

6

Advanced CNC controller

This machine can be equipped with imported CNC systems, including Mitsubishi (Japan), Fanuc (Japan), Siemens (Germany), and other branded CNC controllers.

The three-axis servo motors and amplifiers are supplied as a complete set by the system manufacturer.

The X, Y, and Z axes are driven by AC servo motors as the power source, with ball screws as the transmission components.

The ball screws are fixed and supported at both ends.

For the three-axis bearings, imported special precision bearing sets are used for support with bidirectional pre-tensioning, ensuring the feed rigidity and service life of the screws.

For Y-axis ball screws longer than 6 meters, an advanced auxiliary support structure is provided, which effectively prevents accuracy errors caused by the sagging of long-travel screws due to gravity.

The Z-axis motor is equipped with an automatic brake function.

In the event of a power failure, the brake automatically locks the motor shaft to prevent rotation.

7

refrigeration equipment

The electric control cabinet is equipped with a heat exchange fan, and an air conditioning cooling unit is also available as an option.

The high-performance heat exchanger maintains a constant temperature inside the electric control cabinet, protecting electronic components, controllers and motor drivers.

8

Working Lamp

Waterproof working lamp with soft light for safe and comfortable operation.

9

Spindle & Tool Change

Optional beltdrive or directdrive highspeed spindle. Buffer type tool unclamp mechanism protects spindle and bearings; pneumatic cylinder improves tool change efficiency.

10

Mechanical Structure

Beam gantry structure without hydraulic system, featuring low noise, stable movement and no resonance.

11

Spindle Thermostatic System

Oil chiller keeps spindle at constant temperature during highspeed rotation.

12

Introduction and characteristics of three-axis motors and spindle motors

The main shaft can be optionally equipped with a gearbox or ZBF reduction gearbox structure, which can increase the main shaft torque. The reduction ratio is 1:4, standard. As shown in the following figure;

13

The standards that CNC machining centers comply with

The ambient temperature tested by GB/T shall comply with the provisions of GB1093-89

2.Precision execution standard :GB/T19362.2-2017

3. The electrical system of the machine tool complies with the GB 5226.1-2008 electrical standard

14

Machine lubrication, lubrication of machine tool are divided into two forms: automatic grease lubrication, thin oil lubrication.)

Grease-lubricated parts: Three coordinate bearings;

Automatic thin oil lubrication parts: ball screw pair, linear guide rail, friction guide rail pair composed of cast iron and plastic coating. The automatic thin oil lubrication is a fully automatic mode with timed and quantified operation. The action is automatically controlled by the numerical control system and can be detected and alarmed. For details on the use of oil, please refer to item 9.

15

machine tool protective device

1,The bed guide rail (X-axis) of the machine tool adopts a metal steel plate telescopic protective cover, with a force of 200KG per square meter. The beam guide rail (Y-axis) adopts bellows-type protection. The entire machine tool adopts simple protection to prevent iron filings and coolant from splashing, allowing the operator to work in a safe and comfortable environment. The standard sheet metal is a simple version of sheet metal (sheet metal appearance pictures are provided in the contract).

2,If the user requires fully enclosed sheet metal, it should be noted in the contract when purchasing that it is a customized version.

16

Paint color and packaging

1,The color of the machine tool is mainly iron gray, and the standard color mark of the manufacturer shall prevail. If the user has special requirements, the color requirements should be clearly stated when signing the agreement.

2,The standard for the external protection of machine tools is sheet metal and powder coating. Except for the electrical cabinets and machine tool accessories which are packed in sturdy wooden cases, the main machine tool is transported as a bare machine to ensure the installation period of the machine tool.

17

Machine tool foundation

1,The manufacturer provides the foundation drawings of the machine tool. The user must implement them in accordance with the drawings. The foundation must be a solid, rigid, smooth concrete-reinforced structure and meet all the requirements of the foundation drawings (for details, see item 10).

2,The standard installation location for the equipment is ground installation. The main unit and all related accessories are placed on the ground. If there is a height limit in the factory building, the foundation can be sunken and it should be noted in the agreement; otherwise, it will not be sunken by default.

3,If the equipment foundation is substandard, the manufacturer (service personnel) shall be obligated to put forward requirements. If the user does not adopt or modify them and installs the substandard foundation, it will cause the machine tool to deform, fail to meet the precision requirements for use, or have excessive mechanical load during the future use of the equipment. The user shall bear the service fees.
