Corn milling cutter is also called spiral milling cutter, the blade like corn kernel and then the cutter body in a spiral arrangement; because corn milling cutter has large metal removal rate so it is usually used for rough milling, also it can be used for heavy square shoulder milling, deeper or thicker edge milling and groove milling and other machining,.
What are the advantages of corn milling cutter?
(1)Good chip separation performance, large chip holding space, chips are not easy to block, suitable for strong milling, especially for CNC milling machine.(2) Due to the spaced distribution of inserts, the cutting fluid is easy to be injected, which can give full play to the cooling and lubricating effect, thus improving the milling speed and feed rate.
(3) With the use of carbide material, high-speed milling is possible. When the milling speed is not high, it can increase the life of the milling cutter several times, which is suitable for CNC milling machine and assembly line processing.
Shrink fit tool holder are also called heat expandable tool shanks. The heat expansion tool shank heating unit has an induction coil that allows precise heating
of the area of the tool inserted in the tool shank. After inserting the tool, the shank is cooled for a period of time, which can be accelerated by means of a cooling
sleeve. After the shank has cooled the tool is clamped tightly to the shank by its contraction force. Tools clamped by thermal expansion and contraction have a
high clamping force and can withstand high torques. Combined accuracy within 0.003mm
Hydraulic toolholder is a widely used toolholder, the clamping method of this toolholder is different from the traditional toolholder system, tightening only a pressurized bolt, when the bolt is tightened, it will push the sealing block of the piston to generate a hydraulic oil pressure inside the toolholder, the pressure is uniformly transmitted from the circumferential direction to the steel expansion sleeve, and then the expansion wall will be clamped to the tool, with a high clamping accuracy. Moreover, the hydraulic toolholder can realize the change of diameter by changing the barrel clamp, which is more adaptable and economical. Some customers may have questions, why the hydraulic toolholder does not clamp the tap? Hydraulic shank for tapping a little too big for the thread requirements are relatively not so high, and tapping the chip space is small.
