Quick facts about SPV Spintec s hydraulic chucks! Why should you use SPV Spintec s hydraulic chucks? Permits machining with much closer toleranses. Quicker and simpler tool changes. Runout accuracy All of our hydraulic chuck models are made with runout accuracy better than 0,003. This means that you can machine to closer tolerances and tool lifetime is extended - giving you better overall economy. Our different types of hydraulic chucks Type HCF / HCF+ Short standard chuck Type HCFL / HCFL+ Extended standard chuck Type HCP+ Pen-chuck in two Type HCPK+ Long tapered chuck Type HCK+ Extra short chuck Type HCPS Extra long and slim pen-chuck 6

Facts about SPV Spintec s developed milling-membrane - The Plus-membrane [+] SPV Spintec s hexagonal milling membrane (+membrane) permits though, vibration-free milling. A highly stable tool anchorage makes it possible to machine at greater feed rates and with greater axial and radial depths of cut than normally recoended. Limitations of conventional hydraulic chucks milling. specially shortened hydraulic milling chucks with overall economy. History of development The development started when British Aerospace in cutting tools. BA tried several coercially available retention systems developed the hexagonal milling membrane which was them to double both radial and axial cutting depths.
