Product Features

  • 01
    This machine tool mainly uses the grinding wheel to grind various materials such as steel, cast iron and non-ferrous metals. Depending on the material and shape of the workpiece, different clamping and positioning methods can be used. Generally flat surfaces can be ground using electromagnetic chucks or directly fastened to the workbench; flat surfaces, right-angled surfaces, arbitrary angles, cylindrical end surfaces, etc. can be ground on fixtures (custom-made fixtures).
  • 02
    The spindle grinding head body is fixed on the column and moves up and down (Z direction), the sliding seat moves forward and backward (Y direction) along the main machine, and the workbench moves left and right (X direction) on the sliding seat.
  • 03
    The machine's columns, main base, head base, and workbench are all made of high-grade cast iron and designed with the aid of three-dimensional computer software for optimization. The interior of the structure is reinforced with thick ribs to improve toughness and prevent deformation.
  • 04
    The X-axis uses an independent hydraulic station, which uses a hydraulic cylinder to push the worktable back and forth on the main frame, achieving smooth and smooth X-axis movement with minimal impact from temperature rise on the machine. Slow overflow can make the worktable move at the slowest 2m/min, which has special effects on grinding hard and brittle materials.
  • 05
    The Y-axis uses an AC motor connected to the ball screw through a belt. The frequency converter speed regulation drives the sliding seat to move forward and backward on the main base to realize the Y-axis feed movement. It operates more smoothly and reliably with less noise than the front and rear controllers of the industry.

Component Description

Three-axis guide rail

The X-axis adopts a flat and a V-type design, which is suitable for heavy-duty and form grinding. The slide rail surface of the workbench is covered with original American Teflon (Turcite-B) to reduce the damping coefficient and make the workbench run smoothly. It has exquisite craftsmanship The manual scraping operation is combined with the automatic lubrication system for forced lubrication to ensure accuracy and durability and extend the service life of the machine.

The Y-axis slide rail adopts a double V-rail design to adhere to the Turcit-B, and is precision scraped by hand to ensure smooth movement.

The Z-axis slide rail adopts a precision sliding guide rail with a large contact area. The precision grinding-grade ball screw is driven by a Mitsubishi servo motor. It has high rigidity and sensitive response. The minimum feed accuracy can reach 0.001mm.


Spindle groupThe spindle is the heart of the machine tool, and the accuracy of the spindle is a symbol of the quality of a machine tool. All 408 series machine tools use Taiwan's famous brand Pusen spindles, equipped with wide columns and high-power spindle motors, which have high cutting force and high accuracy maintenance. The inside of the spindle is filled with special high-grade grease and a unique labyrinth seal protection design, making the spindle maintenance-free and long service life.
Automatic grinding settingsAutomatic grinding can be set to rough grinding, fine grinding, and smooth grinding. The amount of feed, the number of feeds, and the number of smooth grinding for various grinding methods can be directly input, that is, the menu selection mode, which can realize multi-machine operation by one person.
Control systemIt adopts Japanese Mitsubishi servo motor and Mitsubishi PLC control system, which has fewer faults and is easy to maintain, modify and monitor. Maintenance centers are located around the world.
LCD touch screen panel settingsLCD touch screen, soft key panel, various grinding condition settings are clear at a glance, the touch screen is equipped with various grinding methods, and the operation is simple and convenient. It is easy to learn and understand, and does not require professional training. Its parameters are stored in flash memory (Flash RAM), so there is no problem of data loss due to power outage. The front and rear feed can be set through the buttons on the control panel, and the tool can be set by inching left and right.
lubricatingThe forced intermittent lubrication device can automatically and completely lubricate the entire machine, while also avoiding excessive lubricating oil and unnecessary oil production.
Remove dandruffStandard magnetic separator improves cutting surface quality and reduces cutting fluid replacement time.
Machine tool protectionThe standard ship-shaped splash guard and large rear wall panel prevent the cutting fluid in the workbench from splashing outside the workbench.
Use environmental conditions

Relative humidity: 35～90%R/H (no condensation)

Ambient temperature: 0℃_x005f∽40℃

Air medium: non-corrosive medium

Light: Sufficient and well ventilated

The machine tool should operate stably for a long time under the above working environment.

Operation and maintenance spaceThe dimensions of the G408S machine are 3600mm in length, 2700mm in width and 1900mm in height. For safety reasons and convenience in operation and maintenance, the space must be larger than the size of the machine.
