Precision Expanding Mandrel Set 1/2"-1", 5 Mandres & 5 Sleeves

Product Information

These models utilise the same precision mandrels, expanding sleeves and locators as our CNC Expanding Mandrels. Bullring mandrels:This mandrel consists of a live center with interchangeable rings that can accommodate a wide variety of large-diameter parts.

Availability of multiple sleeves for work with greater length-to-diameter ratios, eliminating wobble and chatter. Mandrels make the workpiece rotate around the center only, increasing the jobs’ accuracy. Without proper support of the workpiece, there’s a chance for the job operation (e.g., drilling, boring etc.) to fail. PTG produce and supply precision expanding mandrels capable of automatic clamping in component bores, achieving the highest accuracy and holding power to resist the cutting forces imposed on the work piece.The step mandrel isn’t plain like plain mandrel but has step collars of different diameters fitted with it. This allows it to be used for various diameters of workpieces. Step mandrel is used when the inner portion of the workpiece is in the form of steps, which makes step mandrel the right choice. Gang Mandrel

The expanding mandrel can accommodate different diameters of workpieces ranging from 0.5m to 2mm. This range can be increased with a change in brush size. Ring mandrels Mandrels used for holding make the workpiece rotate around the center only, increasing the job’s accuracy. Meanwhile, the ring mandrels are used to forge or reshape rings.

These models utilize the same precision mandrels, expanding sleeves and locators as our CNC Expanding Mandrels There is a slot at both ends of the mandrel. The larger diameter end has a slot for the lathe dog, while the other has a protected center hole for the dead center. This mandrel type is used when the workpiece is plain and is available in different sizes from 44m to 450mm. Step Mandrel

Gripping a workpiece by its inner diameter (ID) rather than its outer diameter (OD) is a workholding option that many job shops fail to consider when turning or grinding parts. However, this technique offers a number of advantages, especially in the machining of workpieces with complex surfaces. Kitagawa Europe produces a series of CNC expanding mandrels designed for a range of spindle types that offer more flexibility in workholding than people might think. Hardinge is the expert in precise part length control, pioneering the Dead-Length 5C and 16C collets for high-production manufacturing. Our Sure-Grip Expanding Collet Systems feature built-in part length control with a double-angle design, ensuring precise workpiece lengths by securely locating them against the arbor face or a machineable work stop. This stability results in heavier cuts, improved surface finishes, and tighter tolerances, making it easy to machine long parts. We also offer custom Sure-Grip Collets for special spindle, sub-spindle, mill table, Swiss, and multi-spindle machine applications. You can even get splined or serrated surfaces for unique grips or recessed draw-plug styles for short gripping challenges. Universal location spigot mount enables this ID workholding system to be easily moved from machine to machine as jobs require. Forging and reshaping: Ring mandrels (also called triblets) are used in the jewelry industry for forging and reshaping rings on them. Expanding mandrel has a slightly complex construction. It has a mounted bush over a tapered arbor, which has a tapered hole with three longitudinal cuts. Two slots are cut nearly through, while the third cut is of full length. This construction allows the expansion of split bushing within a limit.

Info

The line is standardised on most common gripping ranges and spindle types, and the company maintains a database of machine tool spindles and drawtubes to enable customization of drawtube connectors. Additionally, Kitagawa Europe offers a number of specialized systems to fit each company’s individual needs. Kitagawa Europe can supply systems with multiple expanding sleeves or mandrels that can support workpieces with IDs as large as 635mm. Although typically used in turning or grinding applications, our expanding mandrels can be adapted for use on milling machines with special fixtures as well. A solid mandrel is a cylindrical, tapered bar whose one side is larger in diameter than the other. It is the simplest type of mandrel generally available in most machine shops. It is also known as the plain mandrel.
