The aspects of “chip control” that you should check when workpiece damage or poor dimensioning are detected during Swiss type CNC automatic lathe machining

Have you experienced these problems in your day-to-day machining ? Workpiece damage Poor workpiece dimensioning There are a variety of possible causes, but in this column, from the viewpoint of “chip control”, we will introduce tips for solving workpiece defects. Let’s look at the chips. A B What did the chips look like after machining and you experienced a problem with workpiece damage or poor workpiece dimensioning? Were there any broken chips…

Tips for effectively cutting nickel-based alloys by knowing the material’s characteristics

Nickel-based alloys are of course mainly composed of nickel. These alloys are highly resistant to heat and often used for aircraft engine parts that are exposed to high temperature conditions. Machining of nickel-based alloys is very difficult because it differs greatly from general steel. Many manufacturers have experience machining nickel-based alloys with cemented carbide tools. Machining is difficult and the insert edges are quick to wear down. In this article, we will…

How to Make Ceramic Cutting Tools from Scratch

Do you know how ceramic cutting tools are made as described in my previous column, “Two reasons why ceramic tools can perform high-speed cutting”? Many people understand how carbide tools are made, but do you know how ceramic tools are made? In this article, we will discuss the process of making ceramic tools. 1. Blending process This is the process of making the base of the ceramic insert. It consists of two…

Two Areas to Check When Coaxiality is Not Achieved During Swiss CNC Lathe Machining

When I machined the workpiece in the drawing, shown below, the part was No Good. You see that the part does not meet the Coaxiality requirements on the drawing. What should be done to meet the Coaxiality? Coaxiality is very important in Swiss-type CNC automatic lathe machining, where “high precision” parts are required. This time, we will discuss the two points to check when coaxiality requirements are not met in Swiss type…

“Two” checkpoints and measures to be checked when “Roundness” does not come out in Swiss-type CNC-automatic lathe machining-NTK Cutting Tools Lab

Do you know what the diagram below represents ? This diagram shows the measurement result of a workpiece that is out of “roundness“. Roundness is important for “high precision” CNC automatic lathe machining. This article will introduce two points to check when “roundness” is not achieved in Swiss-type CNC automatic lathe machining. Checkpoint when Part Roundness is an issue: ① Guide bushing First- Check the Gripping Force of Guide Bushing The number…

5 types of ceramics used to make cutting tools

When you hear the word “ceramic”, the first thing people may think of is the “white” material used for plates and sanitary ware (toilets). But that type of ceramic is just one of a number of ceramics. There are as many as five ceramics used for cutting tools. In this article, we will introduce the 5 types of ceramic used in cutting tools. What is ceramic in the first place? In a…

The difference between a Swiss type CNC automatic lathe and a traditional CNC lathe and the cutting tools used

A Swiss type CNC automatic lathe and a CNC lathe, they are similar lathe machines, but did you know they are completely different? In this edition, we will introduce the 4 differences between the cutting tools used based on the mechanical structure of Swiss CNC automatic lathes and CNC lathes. What is the difference between a “Swiss CNC automatic lathe” and a “CNC lathe”? forte: We are good at machining a large…

Two reasons why ceramic tools can be used for “high-speed cutting”

If you hear “ceramic tool”, does an image of it “breaking” come to mind? Like if you drop a tea cup, it’s breaking, right? In this article, we will discuss two reasons why ceramic tools can realize significant “productivity improvement” at the manufacturing site. Question: What is ceramic for tooling in the first place? Isn’t it the same material used for pottery? Answer: It is completely different from material used for pottery….
