FANUC Payload Checker.xls Free Download

This Excel spreadsheet is provided by FANUC as an aid to determining the Wrist Load conditions of particular robots.

Every effort has been made to ensure that the spreadsheet data and formulas are correct, but FANUC does not guarantee that it is free of errors.

There may be some error margin between the load calculation result of this Excel file and the load calculation result of the robot controller.

The value of the gravitational acceleration used to calculate from V7.20 of the Excel file is changed from 9.81 to 9.8. Therefore, there is some error margin between the load calculation result of the Excel file on the previous version, 

the load calculation result of the robot controller, and the load calculation result from V7.20 of the Excel file.

Fastener Design Manual PDF Download for Free,Helical Spring Washer is Useless for Locking

This manual was written for design engineers to enable them to choose appropriate fasteners for their designs. Subject matter includes fastener material selection, platings, lubricants, corrosion, locking methods, washers, inserts, thread types and classes, fatigue loading, and fastener torque. A section on design criteria covers the derivation of torque formulas, loads on a fastener group, combining simultaneous shear and tension loads, pullout load for tapped holes, grip length, head styles, and fastener strengths. The second half of this manual presents general guidelines and selection criteria for rivets and lockbolts.

Why was the helical spring washer abandoned? I was shocked after reading the results of the finite element analysis

Helical spring washers can be seen everywhere,but foreign production of machine tools, robots, manipulators, chemical pumps and other high-end equipment can hardly see helical spring washers, is it foreign engineers in order to cut save costs?

What is the difference between linear motion and hard box guideways, and how CNC to choose right guideways?

The guide rail on the machine tool is divided into two kinds: linear rail and hard rail, the accuracy of the linear rail is higher than that of the hard guideway, but the hard rail is more durable and durable.

1. Linear guideway

It is our common linear guide rail, the linear guide rail itself is divided into two parts: the slide rail and the slider, the slider has an internal circulation of balls or rollers, and the length of the slide rail can be customized. It is a modular component, a standardized series of individual products produced by specialized manufacturers, which can be installed on the machine tool and disassembled and replaced after wear. The linear rail is rolling friction, which is fast, has low resistance, and is also convenient for lubrication.
