Hydraulic chuck is an important accessory for clamping workpieces in CNC turning. For general rotary parts, ordinary hydraulic chucks can be used; for parts whose clamped parts are not cylindrical, special chucks are required;
Spring chucks are required when machining parts. For parts with a large ratio of axial size to radial size, it is necessary to use a live center installed on the hydraulic tailstock to support the tail end of the part, so as to ensure the correct processing of the part. There are common hydraulic tailstocks and programmable hydraulic tailstocks.
