FAQ

Q: What is flat grinding?

What is flat grinding?

Flat grinding, sometimes called Blanchard grinding, is a surface grinding method that removes irregularities on a flat plate or part. Both processes are also known as rotary surface grinding. This grinding process leaves a unique pattern on the surface that is often highly desirable.

What are your flat grinding capacities?

At Minnesota Grinding, we can provide flat grinding on parts that are up to 10 inches by 30 inches by 12 inches high. We can also provide double disc grinding for parts up to 9 inches maximum OD for through feet grinding and up to 8.675 inches square for in-feed grinding. Parts are between 0.032 and 3.5 inches in thickness. Blanchard grinding can be completed on parts up to 42 inches corner to corner.

What are the advantages of precision grinding?

Precision flat grinding offers a smooth, flat surface, free from irregularities. With the use of precision grinding systems, parts can be produced quickly, efficiently, and at the lowest possible cost.

What materials can be ground using flat grinding?

Blanchard and flat grinding can be done on most types of metals. This includes both non-ferrous and ferrous metals including aluminum, stainless steel, cast iron, mold plate, bronze, and copper.

Q: What is jig grinding?

What is jig grinding?

Jig grinding is the ideal choice when parts and components have to meet exacting standards and tolerances. The jig grinding process is complex and requires an experienced operator for manual equipment, as well as in setting up the new options in automatic precision jig grinding machines.

What are your jig grinding capacities?

Our jig grinding machines can handle parts that are up to a foot in height, and we can produce holes that are up to 3.5-inches deep with diameters of between .025 and 3.25 inches.

What is the typical tolerance level of jig grinding?

Our expert fabricators are able to produce not only the specific hole diameters required, they also have a true position of up to 0.0005 of an inch. This is true for both our manual and our automatic systems.

What are the advantages of precision grinding?

The use of automated precision jig grinding is much faster than older, manual equipment, which means higher degrees of accuracy at a lower cost per unit.

What materials can be ground using the jig grinding?

Jig grinding can be used on any type of metal or alloy. This includes stainless steel, aluminum, and carbon steel. For the aerospace industry as well as for some other applications, superalloys such as Inconel and Hastelloy can also be ground using this equipment and process.

How much does it cost to get jig grinding service?

There are several factors that impact the cost of jig grinding. For an accurate quote, complete the online form or call us at 763-535-4445.

Q: What is internal grinding?

What is internal grinding?

Q: What is honing?

What is honing?

Honing is a precision process that is used on the inside diameter of a part or component. It is completed as a final finishing step in smoothing the surface and removing even the slightest of irregularities. It is also ideal in achieving extremely-high cylindricity tolerances. On the surface of the part, it is used for the same purpose, but uses a light abrasive on the surface to create a smooth finish.

What are your honing capacities?

At Minnesota Grinding, we have experience in working with OEMs across a wide range of industries. We can handle both large and small orders, and with small parts to larger components.

What are the advantages of honing?

As a final step in the finishing of a part, honing is essential to provide a smooth, even and uniform surface. This is required both for aesthetics on some parts, but also to remove even virtually invisible surface variations.

What materials can be honed?

Any type of metal or alloy can be honed. The key to working with some of the more exotic metals and alloys is to carefully choose the correct abrasive material. As there is limited removal of surface material during the honing process, it is not utilized in place of grinding, which is better for the removal of larger amounts of surface stock.

How much does a honing service cost?

The best way to obtain an accurate quote for your honing job is to contact our team at 763-535-4445 or send in a request form through the website for specific information.

Q: What is lapping?

What is lapping?

Lapping is a very specific process that uses an abrasive compound that is rubbed against the surface of a part or component using both a rotary (circular) and reciprocating (back and forth) movement. This is done very slowly and removes only a small amount of the surface in the process. It is typically done when extremely tight tolerances are required, or when a part, component, or surface has to be extremely flat.

What are your lapping capacities?

Minnesota Grinding can provide lapping for parts up to a thirty-six inch outside diameter, and up to eighteen inches in height. We have the equipment and the experience to manage small to large volume orders, and we work closely with our customers to optimize the process to keep costs down.

What are the advantages of lapping?

The smoothing and finishing nature of the lapping process creates a smooth surface that is free from even minor surface irregularities. The metal does not become shiny through the process, which also offers an aesthetic advantage for many types of applications.

What materials can be lapped?

At Minnesota Grinding, we focus on the lapping of metals. However, the process can also be used with ceramics, glass, silicon materials, and a wide-range of different plastics and composites.

How much does it cost for the lapping service?

Lapping can be a time-intensive process. For an accurate quote on your lapping requirements, submit a request for quote form through the website, or get in touch at 763-535-4445.
