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
    This surface grinder uses a single column fixed on the base. The spindle grinding head body is fixed on the column to move up and down (Y direction). The sliding frame moves forward and backward (Z direction) along the main machine. The workbench moves left and right (X direction) on the sliding frame. move.
  • 03
    The machine's columns, main engine, and machine head are all made of high-grade cast iron. Three-dimensional computer software is used to assist in the optimization design. The preparation of the internal stiffeners of the structure is analyzed and stress-relieved to improve toughness and prevent deformation.
  • 04
    The X-axis uses an independent hydraulic station and hydraulic cylinder to push the workbench back and forth on the main base to achieve smooth and smooth X-axis movement.
  • 05
    The Y-axis guide rail adopts precision slide rail to ensure the spindle runs smoothly up and down. The precision ground ball screw is driven by a Mitsubishi servo motor, which is sensitive and improves the feed accuracy. The minimum feed unit can reach 0.001mm. The MPG electronic handwheel replaces the traditional handwheel, making the feed operation more convenient.
  • 06
    The Z-axis uses an AC motor connected to the screw through a belt to drive the worktable to move forward and backward on the host to achieve smooth Z-axis feed.

Component Description

Three-axis guide rail

The X-axis and Z-axis guide rails are pasted with American Turcite-B wear-resistant sheets. Its high load and low wear can ensure the minimum movement and the machining accuracy is easy to control.

The entire set of Y-axis slide rails is hardened, and the head base is precision ground to have low friction coefficient and shock-absorbing performance.

The Z-axis uses an ordinary screw, which has self-locking force, and uses automatic intermittent lubrication of the screw to make the screw move smoothly and achieve the lowest wear of the screw.

Spindle groupThe spindle is produced by a professional manufacturer in Taiwan, and is equipped with Japanese original NSK high-precision matched bearings. The accuracy can reach within 0.003mm, and it requires no oiling for life.
Automatic grinding settingsAutomatic grinding can be set to rough grinding, fine grinding, and smooth grinding. The touch screen can directly input the amount of feed, the number of feeds and various grinding methods.
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.
lubricatingAn automatic non-circulating lubrication system is used to supply oil to each guide rail and screw rod, ensuring that all key parts are properly lubricated at any time.
Remove dandruffAccording to the customer's processing requirements, a magnetic separator can be selected to protect the environment and extend the time for changing the cutting fluid.
Machine tool protectionThe X-direction is protected by three-proof cloth, and the Z-direction rail is protected by sheet metal. It has a clean appearance, good protection effect, and is sturdy and durable. Standard large splash-proof wall panels prevent cutting fluid from flowing into the guide rails and extend the life of the machine.
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 G818S machine are 1800mm in length, 1400mm in width and 1800mm in height. For safety considerations and convenience in operation and maintenance, the space must be at least 500mm larger than the machine dimensions.
