PURROS Drill bit grinder – Grinding wheel

  1. abrasive grain

The grinding wheel of different materials is suitable for grinding different kinds of cutting tools. Different parts of the tool need to be used in different sizes to ensure the best combination of blade protection and processing efficiency.

Alumina: used for grinding HSS drill bit. The grinding wheel is cheap and easy to be modified into different shapes for grinding complicated knives.

Silicon carbide: used to modify the CBN wheel and diamond wheel.

CBN (cubic boron carbide) : used for grinding HSS drill bit.

Diamond: used for grinding HM drill bit.

  1. Shape of grinding wheel

In order to facilitate the grinding of different parts of the tool, the grinding wheel should have different shapes. The most common ones are:

Parallel grinding wheel (1A1): grinding top Angle, outer diameter, back, etc.

Disc wheel (12V9,11V9): grinding spiral groove, the main of milling cutter, cutting edge, trimming blade, etc.

After a period of use, the grinding wheel needs to be modified (including plane, Angle and rounded Angle R). The grinding wheel must always be cleaned with the cleaning stone to clean up the chips to improve the grinding ability of the grinding wheel.

3 Tips on How to Keep Your End Mills Sharp

Mold manufacturing is a process of removing materials, which makes cutting tools (such as drills and end mills) the pillars of any mold manufacturing operation. They make the constantly used cutting tools dull quickly. Since end mill grinders are important in the manufacturing of molds, here are some tips to help keep end mills sharp for production.

Tip one: Buying a new one- In a mold manufacturing process, you can discard an end mill once it is no longer sharp, and replace it with a new tool. However, this can be an expensive method when used for a long-term as cutting tools can be pricey. For cost analysis purposes, if 30 end mills at $20.00 each are required to be purchased every month, that’s $600 each month. This wouldn’t be the most cost-effective technique to keep your end mills sharp, especially if the volume is high. However, this can be justifiable if the volume is low.Continue reading→

What is the cutting edge of a cutting tool?

The cutting edge of a cutting tool is a crucial for the efficiency of the reducing procedure. The highlights of the cutting edge are:

Cutting edge distance for symmetrical sides.
Cutting edge ellipse axis for uneven sides.
Factor K, this is the releation in between Sγ and also Sα. This could likewise be determined by the proportion of both axis of the ellipse. This element explains the kind of the cutting edge.

3 angles: clearance angle, wedge angle, rake (breaking) angle.

Types of the cutting tools (machinings)

Cutting tools with inserts (indexable devices)

Cutting tools are typically made with inserts or changeable suggestions (tipped tools). In these, the cutting edge contains a different item of product, either brazed, bonded or secured on the device body. Usual products for suggestions consist of sealed carbide, polycrystalline diamond, and also cubic boron nitride. Devices utilizing inserts consist of milling cutters (end mills, fly cutters), tool bits, and also saw blades.

Solid cutting tools

The normal device for milling as well as exploration has no unpredictable insert. The cutting edge and also the shank is one system and also constructed of the exact same product. Little devices could not be developed with exchangeable insert.

Kinds of the cutting tools (cutting machinings)

Straight cutting tools consist of tool bits (single-point cutting tools) as well as brings up. Rotating cutting tools consist of drill bits, countersinks and also counterbores, faucets and also passes away, crushing cutters, reamers, and also chilly saw blades. Various other cutting tools, such as band saw blades, hacksaw blades, and also fly cutters, incorporate facets of direct and also rotating activity.Continue reading→

The cutting tool that need to be sharpened: reamer

Reamer is also a cutting tool that often needs to be sharpened. Its grinding method is relatively simple. Because of the higher requirement for the reamer precision, can be repaired 2-5 times generally. Before grinding the reamer, it is necessary to detect the diameter of the cutter. If the diameter is not within the required range, it can be repaired no longer. After grinding, the coating of the reamer has no coating.

The cutting tool that need to be sharpened: drill bit

The cutting tool that need to be sharpened: drill bit

Drill Bit

The drill bit is the best cutting tool for grinding.
The design should consider the need for grinding.
For preprocessing or general hole accuracy, degree of the drill bit grinding is worn at most 20 times. For high precision drilling bit, it can be sharpened 5 times.
