Ringspann's HDDS Mechanical Clamping Mandrel Increases Process Security

Ringspann’s HDDS expanding-sleeve mandrel is designed for clamping spur or taper wheels for gear manufacturing.

 

Ringspann’s HDDS expanding-sleeve mandrel is designed for clamping spur or taper wheels for gear manufacturing. The HDDS, an inner clamping system, is marketed as a mechanical alternative to hydraulic expanding mandrels commonly used in gearmaking. It provides true running accuracy of equal to or less than 5 microns and achieves absolute expansion some four times larger than many other hydraulic clamping fixtures, the company says. 

“Our HDDS can take up workpieces with bores of up to tolerance class IT10,” says Production Manager Joe Thompson. “Most hydraulic clamping fixtures, meanwhile, are only suited to take up workpiece bores up to tolerance class IT7.” 

The advantage of mechanical rather than hydraulic expansion, the company says, is its elimination of leakage risks. This provides more process safety in series production, since even the smallest leakages of hydraulic clamping fixtures can lead to process interruptions, malfunctions and increased repair outlay. The only source of wear for Ringspann’s HDDS is its clamping disks. Furthermore, the clamping mandrel doesn’t need to be taken from the spindle to replace these disks.




Blue Photon's UV Grippers Accommodate Multiple Diameters

Blue Photon’s metric-size, ultraviolet (UV) light transmitting workholding grippers are designed with multiple diameters to hold small to large workpieces.

Blue Photon gripper

Blue Photon’s metric-size, ultraviolet (UV) light transmitting workholding grippers are designed with multiple diameters to hold small to large workpieces. The grippers are inserted into a fixture, and the workpiece is secured to the grippers with the company’s BlueGrip gel-like adhesive material. UV light is transmitted through the core of the gripper for 60 to 90 seconds to cure the adhesive, bonding the gripper to the part. The workholding device is said to improve tolerances and part access, reduce scrap and eliminate extra processes.




SMW Autoblok's SJL Power Chuck Grips Thin-Walled Workpieces

SMW Autoblok’s SJL six-jaw (2+2+2) equalizing and self-centering power chuck is designed to provide high accuracy with thin-walled and deformation-sensitive workpieces.

SMW Autoblok SJL

SMW Autoblok’s SJL six-jaw (2+2+2) equalizing and self-centering power chuck is designed to provide high accuracy with thin-walled and deformation-sensitive workpieces. The SJL can be switched from a 2+2+2 lever equalizing chuck to a classic six-jaw self-centering chuck depending on application requirements.

Utilizing the 2+2+2 lever balance capability provides high concentricity and axial runout accuracies by ensuring that the grip force of each jaw set equalizes as pairs and is in contact with the workpiece continuously. This minimizes any deformations or inaccuracies of raw materials.

The six-jaw self-centering option provides a concentric clamp locking plate for all sequential six jaws, enabling the chuck to hold round, machined diameters and thin-walled workpieces that require equal wall thicknesses. Specifically designed with centrifugal force compensation, this feature provides constant gripping force at higher speeds and feeds, vastly reducing production time, the company says.

The SJL is Proofline-sealed and protected from contamination while providing consistent lubrication for long maintenance intervals. This advanced power chuck accepts either tongue-and-groove or metric serrated top jaws and is available in sizes ranging from 225 to 400 mm.




Dormer Pramet Offers Cutting Tools for Maintenance, Repair Applications

Dormer Pramet offers a range of cutting tools and accessories aimed at maintenance and repair (MRO), including drills, taps, dies, reamers, end mills and rotary burrs.

Dormer Pramet MRO drills

Dormer Pramet offers a range of cutting tools and accessories aimed at maintenance and repair (MRO), including drills, taps, dies, reamers, end mills and rotary burrs. To cover the breadth of applications within the MRO segment, there are drills for general purpose machine and portable drilling. These include the popular HSS R10 series for right hand drilling and HSS L10 series for left hand drilling. Also included are the carbide DC series of center drills. There is a specific selection for sheet metal drilling and spot weld drilling.

According to Dormer Pramet, the drill program is highlighted by the MRO drills that cover most ferrous applications and are suitable for use in portable drilling, drill presses and other operations within this segment. The MRO drills are available in jobber length (301JD), heavy-duty jobber length (331HD, 332HD and 333HD), mechanics length with “tri-flat” shanks (321MD), stub length (331SM, 332SM) and reduced-shank (341SD, 342SD). Within this selection, different surface treatments are available to cover the range of MRO operating conditions. The program contains conventional 118-degree point geometries as well as 135-degree self-centering split points for more challenging applications. Sets within each style are available in a rust-resistant, water- and shatter-proof case.




Big Kaiser's FLM, ELM Chipbreakers Designed for Cutting Long-Chipping Metals

Big Kaiser’s FLM and ELM insert chipbreakers are designed to improve surface finish in long-chipping materials.

ELM and FLM chipbreakers from Big Kaiser

Big Kaiser’s FLM and ELM insert chipbreakers are designed to improve surface finish in long-chipping materials. Long chips that are difficult to evacuate can lead to poor surface finishes, reduced insert life and machine crashes.

The FLM 3D chipbreaker design, used on PCD-tipped inserts, is well-suited to finishing aluminum components, where traditional flat-top inserts may produce a large nest of chips that is difficult to remove from the bore and/or tool. Three different radius options are available: 0.008", 0.016" and 0.031" for the TCGT2 (1.5) insert.

The ELM chipbreaker, used on cermet inserts, is well-suited to finishing mild or construction steels. Available in a 0.008" radius and combined with a light depth of cut, this chipbreaker provides a high-shear angle to shorten chips, and improve both chip evacuation and finish.
