Keyence's Security Sensor Utilization Guide to Change Automatic Machine Design

Keyence's Security Sensor Utilization Guide to Change Automatic Machine Design

2026/2/22    

  Here is a note about the "line type sensor sensor" of Mr. Keyens, which is popular in recent FA machines and is a revolutionary product. Complicated sensor position adjustment and luck at the time of equipment start-up...

Samples of steel parts with various types of plating and selection flow drawing based on JIS standards in the background.

Covering types of iron plating|JIS Standard and Optimal Flow Evaluation Summary

2026/2/19    ,

  Here, we make a note of the information for "Aiming to examine the optimum plating from the examination of iron cross section" about the plating process in general. As a machine designer, I have confidence in the design of functions and dimensions, but last...

Comparing Aluminum Frames vs. Can Frames. Eye-catching image examining the advantages of machine mounts in the balance.

Comparison of Aluminum frame and Can making frame in machine stand

2026/2/17    ,

Here, I make a note of "Comparison of aluminum frame and can frame", which examines the configuration of the machine frame used in FA automatic machines, etc.

Linear shaft being induction hardened

What is induction hardening? Drawing instructions and quality control basics that go directly to practice

2026/2/3    

  Here, I make a note about quenching called "induction hardening", which I go to parts such as linear shafts, pins and gears. In the design of the linear shaft, the wear resistance was enhanced...

Swing-type air clamps and link-type air clamps side by side

Air Clamp method and design study|Thorough explanation from calculation to safety circuit

  Here, I make a note about "Method and design and examination of air clamp" which can be used for clamping mechanism. At the site of machine design, "The clamping force that we designed is the actual processing load and the workpiece retention...

Scratch resistance testing of hard-to-scratch transparent resin in the laboratory. Multiple sample plates and testing equipment are lined up.

Selection of transparent resin with few scratches|Thorough comparison of the types and characteristics of machine covers

2026/1/21    ,

  Here, we make a note of "Examination of transparent resin that is hard to scratch and peripheral information" about transparent resin used in machine covers. When designing the safety cover of the machine and the view window of the cleaning equipment, it is specified in the drawings."..

Illustration of a cut model comparing the internal structure of an LM (linear) guide and a linear bush. Technical diagram to visually understand the difference between each ball recirculation system.

Structure Comparison of LM (Linear) Guides and Linear Bushings

  Here is a note about "Structure comparison and usage of LM (Linear) Guide and linear Bush". In a modern production line where 24-hour operation has become the norm, machine designers are truly afraid...

Close-up image of an industrial component with linear shafts and linear bearings for precision machinery on a blueprint.

Linear Shaft Evaluation and Design Complete Guide|Material, Heat treatment, Surface treatment, etc.

  Here is the practical memo know-how about the "linear shaft" used in the guide mechanism. "I want to make a guide mechanism using a linear shaft, but I can be sure which material to choose...

Criteria for Fitting Bearings|Case Studies and Design Points

2025/12/22    

  Here, I make a note about "Judgment criteria / Case studies and design points of whether to press-fit bearings". For many mechanical designers, information on bearing pressure entry is available in the catalog of the published difference table...

Difference between light curtains and area sensors

Difference between light curtain and area sensor/ Concrete Examples of structure and Installation

  Here is a note about "Differences between light curtains and area sensors, concrete examples of structure and installation", which is important for safety design in automatic machines.
