SELECTION CRITERIA

1. PRODUCT APPLICATIONS:

1). CH SERIES: GRINDING MACHINE, MILLING MACHINE, LATHE, DRILLING MACHINE, INTEGRATED PROCESSING MACHINE, EDM MACHINE, BORING MACHINE, WIRE CUTTING MACHINE, PRECISION

2). CE SERIES: INDUSTRIAL AUTOMATION MACHINERY, SEMICONDUCTOR MACHINERY, LASER ENGRAVING MACHINE, PACKAGING MACHINE;

3). CGN/CGW SERIES: PRINTER, MACHINE ARM, ELECTRONIC INSTRUMENT AND SEMICONDUCTOR EQUIPMENT.

 

2. SELECTION OF ACCURACY LEVEL:

C, H, P, SP, UP LEVELS DEPEND ON EQUIPMENT ACCURACY REQUIREMENTS.
 

3. SELECTION OF SIZE:

1). ACCORDING TO EXPERIENCE;

2). LOAD STATUS;

3). IF LINEAR GUIDEWAY IS USED IN CONJUNCTION WITH BALL SCREW, SELECT SIMILAR SIZE AS EXTERNAL DIAMETER OF THE SCREW. IF THE EXTERNAL DIAMETER OF THE SCREW IS 35 MM, SELECT CH35.

 

4. CALCULATING THE MAXIMUM LOAD OF SLIDER:

1). CALCULATING THE MAXIMUM EQUIVALENT LOAD OF A SINGLE SLIDER WITH REFERENCE TO THE LOAD CALCULATION TABLE

2). CONFIRMATION THAT THE STATIC SAFETY FACTOR OF THE SELECTED STRAIGHT-LINE GUIDE SHOULD EXCEED THE VALUE LISTED IN THE TABLE OF STATIC SAFETY FACTOR

LUBRICATION:

IF THE LINEAR GUIDE IS NOT PROPERLY LUBRICATED, THE FRICTION OF ROLLING PARTS WILL INCREASE, AND LONG-TERM USE WILL BECOME THE MAIN REASON FOR SHORTENING THE LIFE. LUBRICANTS PROVIDE THE FOLLOWING FUNCTIONS:

(1). REDUCE FRICTION OF ROLLING PARTS, PREVENT BURNS AND REDUCE WEAR;

(2). FORMING OIL FILM BETWEEN ROLLING SURFACE AND ROLLING SURFACE CAN PROLONG ROLLING FATIGUE LIFE;

(3). PREVENTING RUST.

 

1. GREASE LUBRICATION:

EACH GROUP OF LINEAR GUIDEWAYS CAN BE SEALED WITH LITHIUM SOAP-BASED GREASE TO LUBRICATE THE BEAD GROOVE TRACK BEFORE LEAVING THE FACTORY. ALTHOUGH THE GREASE IS NOT EASY TO LOSE, IN ORDER TO AVOID INSUFFICIENT LUBRICATION CAUSED BY LUBRICATION LOSS, IT IS SUGGESTED THAT CUSTOMERS SHOULD SUPPLEMENT THE GREASE ONCE MORE WHEN THE DISTANCE REACHES 100 KM. AT THIS TIME, GREASE CAN BE INJECTED INTO THE SLIDER BY MEANS OF THE OIL NOZZLE ATTACHED TO THE SLIDER. LUBRICATING GREASE IS SUITABLE FOR SITUATIONS WHERE THE SPEED IS NOT MORE THAN 60 M/MIN AND THE COOLING EFFECT IS NOT REQUIRED.
T : OIL INJECTION FREQUENCY (hour);  Ve : SPEED (m/min)
 

2. OIL (OIL) LUBRICATION:

IT IS RECOMMENDED THAT CUSTOMERS USE LUBRICATING OIL WITH A CONSISTENCY OF ABOUT 32-150 CST TO LUBRICATE LINEAR GUIDES. ZCF CAN INSTALL THE TUBING JOINT AT THE ORIGINAL POSITION OF THE OIL DISCHARGE NOZZLE ACCORDING TO THE CUSTOMER'S NEEDS, SO THE CUSTOMER ONLY NEEDS TO CONNECT THE PRESET TUBING OF THE MACHINE TO THE TUBING JOINT. THE LOSS OF LUBRICATING OIL IS FASTER THAN THAT OF LUBRICATING GREASE. WHEN USING, ATTENTION MUST BE PAID TO THE ADEQUACY OF OIL SUPPLY. IF INSUFFICIENT LUBRICATION EASILY CAUSES ABNORMAL WEAR OF LINEAR GUIDES AND REDUCES THEIR SERVICE LIFE, IT IS SUGGESTED THAT THE FREQUENCY OF LUBRICATING OIL SHOULD BE ABOUT 0.3CM3/HR. CUSTOMERS CAN USE IT ACCORDING TO THEIR USE CONDITIONS. LUBRICATING OIL IS SUITABLE FOR VARIOUS LOADS AND SPEEDS, BUT IT IS NOT SUITABLE FOR HIGH TEMPERATURE LUBRICATION BECAUSE OF ITS VOLATILITY.

DUST-PROOF DEVICE(OPTIONS)
 

1. DUST-PROOF DEVICE CODE:

IF YOU NEED THE FOLLOWING DUST-PROOF EQUIPMENT, PLEASE ADD THE CODE AFTER THE PRODUCT MODEL.


INSTALLATION OF LINEAR GUIDEWAY

THE INSTALLATION METHOD OF LINEAR GUIDE MUST BE SET ACCORDING TO THE OPERATING CONDITION OF THE MACHINE, SUCH AS THE DEGREE OF VIBRATION AND IMPACT FORCE, THE REQUIRED WALKING ACCURACY AND THE LIMITATION OF THE MACHINE.WHEN PAIRING NON-INTERCHANGEABLE LINEAR GUIDES, ATTENTION SHOULD BE PAID TO THE DIFFERENCE BETWEEN THE REFERENCE RAIL AND THE DRIVEN RAIL. THE ACCURACY OF THE DATUM LEVEL ON THE SIDE OF THE DATUM RAIL IS HIGHER THAN THAT OF THE DRIVEN RAIL, SO IT CAN BE USED AS THE SUPPORTING SURFACE FOR THE BED INSTALLATION. THE REFERENCE RAIL IS MARKED WITH MA, AS SHOWN IN THE FIGURE.


 

1. FIXING METHODS

WHEN THE BED IS SUBJECTED TO VIBRATION AND IMPACT FORCE, THE GUIDE RAIL AND SLIDER MAY DEVIATE FROM THE ORIGINAL FIXED POSITION AND AFFECT THE ACCURACY. IN ORDER TO AVOID SIMILAR SITUATION, IT IS SUGGESTED TO USE THE FOUR FIXED WAYS LISTED BELOW TO FIX THE GUIDE RAIL AND SLIDER TO ENSURE THE ACCURACY OF THE MACHINE.
