创建于05.07Installation of oil channel tool holderInstallation and adjustment steps of oil circuit tool holder (external cooling to internal cooling tool holder) 1. First confirm the distance from the center of the oil circuit tool holder (external cooling to internal cooling tool holder) to the positioning position, BT40=65mm; BT50=80mm, please see the specification table (B) and compare it with the distance from the center of the machine tool spindle to the fixed seat. If the distance does not match, the customer adjusts the position of the water inlet hole of the fixing seat by himself and then installs it (the dust cover screw holes on the fixing block and the end face of the machine tool spindle match). 2. Oil circuit tool holder (external cooling to internal cooling tool holder) a. Install the fixing block on the end face of the machine tool and connect the water inlet pipe to the positioning block. b. Installation of oil-circuit toolholder (external cooling to internal cooling toolholder): First loosen the M6 thread on the positioning key so that the positioning column can move up and down freely (there is a spring under the positioning column), and then install the positioning ring on the
创建于03.28Answers to common questions about mold manufacturingWhat are the most important and decisive factors in selecting tool steel? Forming method - There are two basic material types to choose from. A) Hot working tool steels, which can withstand the relatively high temperatures of die casting, forging and extrusion. B) Cold working tool steels, which are used for blanking and shearing, cold forming, cold extrusion, cold forging and powder pressing. Plastics - Some plastics produce corrosive by-products, such as PVC plastic. Factors such as condensation caused by long downtime, corrosive gases, acids, cooling/heating, water or storage conditions can also cause corrosion. In these cases, stainless steel tool steel is recommended. Tool size - Large size tools often use pre-hardened steel. Through-hardened steel is often used for small size tools. Tool

Spade drill diameter range: ø9.5mm~~ø114mm Effective length: 50/70/100/150/200/250/300/350/400/450/500mm The blade design is suitable for deep hole processing. The spiral blade design and central water outlet (internal cooling) optimize the chip removal function. A single tool holder can be equipped with a variety of blades, which is economical and affordable. * The tool bar length can be customized according to processing needs. The range of equipment used is wide (can be used for radial drills, vertical drills, horizontal beds, machining centers and other equipment), and the rigidity requirements of the equipment are not high. The integral cutter head can be accurately centered, the cutter head has chip grooves and chip breakers, and can process deep holes. Spade drills are generally used for medium-speed processing between U-drilling and ordinary drilling. The general blade is high-speed
