Cutting Tools New end mills: Rainford points to precision at Mach
At Mach 2022, Rainford Precision will be putting its know-how in micro-machining into the limelight. On Stand 573 in Hall 20, the company will introduce new additions to its extensive product portfolio with particular emphasis on the Mach debut for its new V-Series of small end mills from Union Tool.
The new V-Series of square, radius and ball nose end mills is a complete line-up of high-quality precision end mills with 3 mm diameter shanks to cater for machine shops undertaking the challenges of small part machining.
With the shanks ground to an h4 finish on specialist grinding machines, customers can be assured of the quality of this new Union Tool series. This level of precision also improves machining performance when undertaking high-speed machining with high-end collets and shrink fit systems. The V-Series is offered in three variants, the VHLS, VHLRS and the VHSLB which identifies the square, radius and ball nosed options. The solid carbide V-Series end mills have been developed with Union Tool’s Hardmax coating technology to provide the perfect combination of hardness, durability and heat resistance for machining hard materials from 40HRc to around 65HRc. This hard-wearing coating makes the V-Series suitable for cutting a wide range of materials from carbon, alloy and pre-hardened steels through to hard steel, heat resistant alloys and much more.
Manufactured from a super micro-grain carbide with a 30° helix, flat land and optimised geometry that demonstrates extreme resilience when machining challenging materials with very small tools, the V-Series is the first choice for machining with tool diameters as small as 0.1 mm. As part of the range that will make a UK exhibition debut at Mach 2022, the VHLS 2-flute range of long neck square end tools is available in diameters of 0.1 to 0.6 mm in 0.1 mm increments with 0.8, 1, 1.5 and 2 mm diameter tools completing the range. The effective cutting length varies from 0.3 mm to 6 mm depending upon the chosen diameter, but most of the series is offered with a choice of cut length geometries to maximise the rigidity and strength of the micro end mills according to application. All diameters are provided with a 38 mm overall length and 3 mm shank diameter with a necked diameter and 16° tapered angle for additional clearance when machining intricate features and surfaces.
Alongside the VHLS square end tools is the new VHLRS short shank long neck radius range of 2-flute end mills. Also manufactured from a standardised 3 mm shank with 38 mm overall length, the VHLRS is available from 0.2 mm diameter to 2 mm with necked and tapered shanks for additional clearance. The 0.2 and 0.3 mm diameter end mills are provided with a 0.05 mm radius whereas the 0.4, 0.5 and 0.6 mm tools are offered with a 0.05 or 0.1 mm corner radius option with a choice of flute lengths to suit specific applications. The 0.8, 1, 1.5 and 2 mm diameter tools provide a choice of effective flute lengths and corner radii from 0.05 to 0.2 mm to meet the specific demands of the end-user.
For extremely small profiling applications and parts that demand the utmost precision, the 2-flute VHSLB range of ball nosed tools is available. This high-precision range of end mills is available with a ball nose from as small as R0.05 mm and extending through 0.1, 0.15, 0.2, 0.25, 0.3, 0.4, 0.5, 0.75, 1, and 1.5 mm. Except for the smallest R0.05 tool that has an effective flute length of 0.3 mm, every tool diameter in the VHSLB range is offered with a wide variety of effective cutting lengths to provide complete stability, strength and rigidity for the specific task at hand.
Visitors to Stand 573 in Hall 20 will also have the opportunity to view a wide selection of cutting tool solutions from world-renowned brands such as Union Tool, Louis Bélet, Delmeco, Gloor, Hobe, Osawa, DTS, Iwata and Atom. Experts from Rainford Precision will also be on hand to discuss ultra-precise machining solutions from Kern, laser micromachining from Lasea as well as micro waterjet machining technology from Finepart.
