SCREW COVER & POST COVER
Screw cover & Post cover are dust-proof metal made cover by expanding method. They can protect to driving parts like ball screw and press machine.
•Expansible spiral shape
•Contribution for dust-proof, disaster prevention, and precision maintenance.
•Superior durability performance
•High precision completion
Protect the ball screw of the machining tools and guard from dust, contamination. Also, prevent from scoring.
•Machining Center •Industrial Machinery •Welding •Machine •Robot
•Mold •Another Machine
EXAMPLE OF USE
•Ball Screw •Spline •Feed Screw
•Cylinder Rod •Shaft •Guide Post
Movie of performance
Below table is standard dimension table. Please show the below 6 dimension point to us. We select correct cover.
Screw Cover Standard Dimension Table
(1)Diameter of screw •Shaft
(2)Effective operation length (L)
(3)Allowable adhesion Length(C)
(4)Allowable large part Max. and Min. diameter(OD: D2, ID :D1)
(5)Use status (Vertical/Horizontal)
RECEIVING JIG DIMENSION
Please make a receiving jig by customer self referring below receiving jig dimension.
As the screw cover involves rotational motion during expansion, please avoid both sauces that are too tight.
•Large part out diameter error =D2-(0～3mm)
•Small part inside diameter error =D1+(0～2mm)
•0～3mm Large and small caliber error during telescopic motion.
*In our company, D2(OD) dimension indication is measured during adhesion length (max. condition)
And D1(ID)dimension indication is measured during effective operation length (min. condition)
It's easily attached to the die set and protects a worker from an accident to occur in a guide part.
Please select the suitable cover from standard dimension list by following 4 items.
Post cover standard dimension list (and attention in the use)
(1)d2 = D4 + 4mm
(2)L > H1 + H2 + S
(3)D1 > D3
(4)W < H1
*The details download PDF from below [specifications / choice list], and refer.
