Expansion Reamers: Precision holes require precision tools. When machinists need an exact size hole, they want the best tool available to achieve the desired diameter. That’s a job for a reamer. The appropriate amount of stock removal for carbide tipped reamers is typically 2-3 percent of the finished hole size. This is so the reamer […]
The flute configuration of a reamer is important. Selecting the correct configuration helps optimize tool life and hole finish. Left hand spiral reamers should be selected for through holes. A through hole has an opening on the other end. If you put your eye up to the hole, you would be able to see out […]
I’m a bowler. I’ve been bowling in leagues for about 9 years now, and while, I have yet to bowl a perfect game (although I have come pretty close) or pick up that unforgiving 7-10 split (I have never come close at all), I have had my own custom ball since I’ve started. As with […]
Coatings can be a bit overwhelming. Here are some things to consider when choosing whether or not to have your tools coated and which type of coatings to choose. The Physical Vapor Deposition (PVD) Process When coating tools, Super Tool uses the Physical Vapor Deposition (PVD) process because it allows for more […]
The majority of requests I receive for special tools ends with something along the lines of “…and I need them tomorrow.” This is frequently possible if semi-finished tools can be used to make the tool the customer is asking for. If the tool has to be made from scratch, forget it. Best case scenario would […]
The first problem and probably one of the most common reaming problems is Poor Finish. Possible causes include unequal chamfers, incorrect margins, excessive spindle runout, chatter, and insufficient cutting action. Below is a table with possible solutions for each of the possible causes of poor finish: Possible Causes Possible Solutions Unequal Chamfers Regrind the reamer […]
The amount of material left in the hole prior to reaming “pre-ream hole size” plays an integral role in the quality of the reamed hole. The pre-ream hole size affects characteristics in the reamed hole including hole finish, hole straightness, tool life, and cycle time. There are several ways in which the pre-ream hole size […]
