7 Steps to Take Before a Laser Calibration Before bringing in a laser-calibration solution, consider the following steps involved in a machine-tool "tune-up." Machine-tool calibration starts with the geometric alignments—level, flat, straight and square
machine tool diagnostic and calibration technology The first step on the road to knowing that parts coming off the machine meet specifications is ensuring in advance that the machine itself is capable of the desired accuracy.

Checking Chuck & Spindle Run-Out Set the “zero” on the dial indicator, as shown in. the Illustration to the right. To check run-out, rotate the spindle.
Five Basic Errors in Shaft Alignment Properly aligned shafts will do more to increase bearing, seal, and rotor life than any other single thing you can do after lubrication.
Table saw alignment Most American style hybrid and contractor saws are constructed in a similar way, so if you need to align your table saw, this article may provide some useful tips.
Detail of CNC machine tool backlash Backlash in the X and Y axis of machining centers is most obvious when milling full circles. If any backlash exists, there will be a nasty witness mark on each quadrant line.
Eliminating Backlash, Part 1: Basics When the axis is commanded to move, the drive motor may turn briefly before movement begins. That delay is the backlash.
Eliminating Backlash, Part 2: Refinements sources of the backlash on a given axis: Leadscrew & Nut, Leadscrew and/or Nut Mounting, Motor Drive Mechanism, Slideways and or Gibs, Machine Flexure and Rigidity
Dial Indicator Alignment Procedure The procedure for doing reverse dial indicator alignment is not a difficult one. There are several steps which need to be taken for a successful alignment job
Use and Care of the Dial Indicator Make the following measurements of a motor of known dimensions to an accuracy of 0.0001 inch: shaft radial runout, inner bearing ring face runout, and outer bearing ring face runout.
Reverse Dial Alignment Mis-alignment can be the most usual cause for unacceptable operation and high vibration levels.
Squaring up your Mill Table left/right movement is referred to as the X axis. Table in/out movement is the Y axis. Headstock up/down movement is referred to as the Z axis.
Laser Non-contact and High-Resolution Dial-indicator for Spindle run-out and 5-axis machines Dial-indicators have been extensively used to check the machine geometry accuracy. However, because of the low resolution and the mechanical contact, its application for precision measurements are rather limited.

Motor Oil Motor Oil From Wikipedia, the free encyclopedia. While the main function is to lubricate moving parts, motor oil also cleans, inhibits corrosion, and cools the engine by carrying heat away from the moving parts.
Lubrication and Oil Analysis Dictionary 625 items, listed from A to Z. Or from A.G.M.A. (American Gear Manufacturers Associations) to ZDDP (Zinc dialkyldithiophosphate).
The Hidden Cost of Oil Changes Unlike changing the oil in your car based upon time or miles, oil changes for industrial equipment should be based on need where no other practical solution to restore proper lubrication is available.
Classification of lubricants General classification of lubricants; Classification of lubricants by application; Classification of lubricants by additives
Engine oil (motor oil) Functions of engine oil stable oil film between sliding surfaces reliable engine operation in a wide temperature range Rust (corrosion) protection Cleaning the engine parts Sealing piston ring Prevention of foaming Cooling the engine parts
Machinery Lubrication Lubricants, Oils, Maintenance. Don't Just Measure Performance … Manage It. Particle contamination control has several components, but it begins with good lubricant storage, handling and application methods.
Lubricant Analysis Supports Predictive Maintenance Identification of the root causes of internal damage is definitely part of effective lubrication management.
Electric Motor Bearing Greasing One of the most important components of any electro- mechanical maintenance program is the lubrication of bearings.
Synthetic & Specialty Lubricants Tribology Tech-Lube is a leader in the manufacturing of specialty, synthetic, and semi-synthetic lubricants, oils, and greases
Synthetic Lubricants All synthetics are not alike. Selection should be based on the optimum base stock type for the application.
