MICRO-QUIK

MICRO-QUIK is a brand specializing in precision boring bars for machining applications, particularly focused on small-diameter internal boring operations. The product line centers on indexable boring bars with shank diameters ranging from 3/16 in to 3/8 in, designed for use in lathes and machining centers where tight tolerances and fine surface finishes are required. The brand is known for its modular quick-change tooling systems that allow operators to swap cutting heads without removing the shank from the toolholder, reducing setup time in repetitive boring tasks. MICRO-QUIK boring bars are available with either AlTiN (aluminum titanium nitride) coating or bright (uncoated) finish. AlTiN-coated variants provide increased hardness and oxidation resistance at elevated cutting temperatures, making them suitable for harder workpiece materials such as alloy steels and stainless steels. Uncoated bars are typically used for non-ferrous materials or where edge sharpness is critical. The bars feature a center-to-cutting-tip dimension that defines the minimum bore diameter achievable, with values as low as 0.0240 in for the QMBB series, enabling micro-boring down to approximately 0.048 in diameter. The product range includes both right-hand and neutral cutting geometries, with corner radii from 0.0030 in to 0.0050 in. MICRO-QUIK bars are manufactured to standard shank tolerances and are compatible with industry-standard toolholders. 3G Electric supplies a selection of MICRO-QUIK boring bars across multiple SKUs, including the QBB and QMBB series, to support precision machining operations in industries such as aerospace, medical device manufacturing, and general engineering. The inventory covers common shank sizes and coating options, allowing procurement specialists to source specific configurations for their tooling cribs. 3G Electric provides logistics support for these items, ensuring availability for global shipments.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang MICRO-QUIK dari 3G Electric.

What is the minimum bore diameter achievable with MICRO-QUIK boring bars?

The minimum bore diameter depends on the center-to-cutting-tip dimension of the bar. For example, the MICRO-QUIK QMBB-040200X has a center-to-cutting-tip of 0.0240 in, allowing a theoretical minimum bore diameter of approximately 0.048 in. Larger bars like the QBB-3602500 with a 0.1725 in center-to-cutting-tip can bore diameters down to about 0.345 in. Always verify the specific bar's geometry against your required bore size.

What is the difference between AlTiN-coated and bright (uncoated) MICRO-QUIK boring bars?

AlTiN-coated MICRO-QUIK bars (e.g., QBB-2301000X) have a hard coating that improves wear resistance and allows higher cutting speeds in ferrous materials. Bright (uncoated) bars (e.g., QBB-3602500) have a sharper cutting edge and are preferred for non-ferrous materials like aluminum or brass, where built-up edge is a concern. Coated bars also offer better thermal protection during interrupted cuts.

Are MICRO-QUIK boring bars compatible with standard toolholders?

Yes, MICRO-QUIK boring bars are designed with standard shank diameters (3/16 in, 5/16 in, 3/8 in) that fit conventional boring bar holders and collet chucks. The shank tolerances are industry-standard, so they can be used in most lathe or milling machine tool posts without modification. Always confirm the shank diameter matches your holder's capacity.

Can I use a MICRO-QUIK boring bar for both roughing and finishing operations?

MICRO-QUIK boring bars are primarily designed for finishing and semi-finishing operations due to their small shank sizes and fine corner radii (0.0030 in to 0.0050 in). For roughing, a larger bar with a more robust geometry would be more appropriate. The bars excel in achieving tight tolerances and good surface finish in small-diameter bores.

What materials are MICRO-QUIK boring bars suitable for?

AlTiN-coated MICRO-QUIK bars are suitable for machining alloy steels, stainless steels, and cast irons. Bright (uncoated) bars are better for non-ferrous materials such as aluminum, brass, copper, and plastics. The choice depends on the workpiece material and cutting conditions. For hardened materials above 45 HRC, coated bars are recommended.

Does 3G Electric supply MICRO-QUIK products?
