Small Chucks Ideal for Micromachining in Confined Areas
Big Kaiser offers its smallest hydraulic chuck for HSK-E25 machine spindles, completing its line of Super Slim hydraulic chucks.
Big Kaiser offers its smallest hydraulic chuck for HSK-E25 machine spindles, completing its line of Super Slim hydraulic chucks. The chucks are ideal for precision finishing processes in confined areas with drills, reamers, ball mills, end mills, diamond reamers and grinding tools. Cutting tools with shank diameters of 3 or 4 mm can be directly clamped for high-speed micromachining applications in the automotive, aerospace, medical, die and electronics industries.
The company designed the chucks to require a single wrench for clamping and unclamping, which is easier and safer than heat-shrink toolholders. They can clamp ultra-small endmills and drills directly without a reduction sleeve. The external body diameter of the chuck nose is 0.551" (14 mm), and a gauge length of 1.575" (40 mm) makes it compact and precise. Each tool is precisely balanced for speeds as high as 60,000 rpm and runout accuracy of less than 3 microns (0.00012") at 5×D.
The hydraulic chucks for HSK-E25 machine spindles are available from stock. They are also available for HSK-E 32 and HSK-E 40 spindles.
A system to be marketed in 2015 will apply ultrasonic vibration from within the toolholder to reduce cutting force and improve the performance of the cut.
I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
