Customer Reviews
Components are pretty good. Fair price.

—— Jackshee Best- USA

Our customer has tested the machined part, now it works well, thank you.

—— Dereck Lammers- Mexico

I used your parts for a assembly project to cut some holes in some 1/8 thin gauge steel. It did start easily into the steel and seemed to cut it with not a lot of pressure.

—— Brady Walter- Canada

I recommend Toxmann products to my friends. Good quality, good service.

—— Connor Smith- USA

The grinding parts make it better for our products to bite. Toxmann makes the best mold parts!

—— Stefan Geitner- Germany

These precision parts are a great addition to our construction company, good quality makes us work more easier.

Company Profile-Toxmann.pdf


Processing & Inspection Machine List.pdf


A rack is a special gear with teeth distributed on a bar. Racks are also divided into spur racks and helical racks, which are used in pairs with spur and helical spur gears respectively; the tooth profile of the rack is straight rather than involute (flat for the tooth surface) , which is equivalent to an infinite cylindrical gear with an indexing circle radius. A rack is a bar-shaped part matched with a gear. It is equal to a segment of the circumference of a gear with an infinite diameter. There are many teeth evenly distributed on one side, which mesh with gears and turn rotation into movement, or movement into rotation. The rack is a long bar with teeth on one side, which can be considered as a segment on a gear with an infinite diameter.

The rack has the following characteristics:

(1) Since the rack tooth profile is a straight line, each point on the tooth profile has the same pressure angle, which is equal to the inclination angle of the tooth profile. This angle is called the tooth profile angle, and the standard value is 20°.
(2) Any straight line parallel to the addendum line has the same pitch and module.
(3) The straight line parallel to the tooth top line and the tooth thickness equal to the tooth slot width is called the index line (center line), which is the reference line for calculating the rack size.

Q1: What are the types of EDM process?
A: Electric discharge machining can be divided into three common types, Die sinking EDM, Wire EDM and hole drilling EDM.
Die sinking EDM.
Wire EDM.
Hole drilling EDM.

Q2: What does EDM stand for in machining?
A: Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges.

Q3: Which material is used for EDM process?
A: Electrodes that are generally used in EDM process are copper, graphite, copper tungsten, silver tungsten, tungsten carbide, brass.

Q4: What is application of EDM?
A: The EDM process is most widely used by the mold-making, tool, and die industries, but is becoming a common method of making prototype and production parts, especially in the aerospace, automobile and electronics industries in which production quantities are relatively low.

Q5: What are the advantages of EDM?
A: Creates complex shapes that would otherwise be difficult to produce with conventional cutting tools. Cuts extremely hard, challenging and exotic materials to very close tolerances for high precision mechanical components.

Q6: What is the difference between EDM and wire EDM?
A: Conventional EDM cannot produce narrower angles or more complex patterns, while wire-cut EDM can be performed. A more precise cutting process allows for more complex cuts. The wire EDM machine is capable of cutting a metal thickness of about 0.004 inches.
