Install ERO/SLO Oil tool holderOil Path Tool Holder (External Coolant to Internal Coolant Tool Holder) Installation and Adjustment Steps
1. First, confirm the center to positioning distance of the oil path tool holder (external coolant to internal coolant tool holder):
BT40 = 65mm;
BT50 = 80mm,
please refer to the specification table (B)
and compare it with the distance from the machine spindle center to the fixed seat.
If the distance does not match, the customer should adjust the position of the water inlet hole of the fixed seat before proceeding with the installation (the fixing block and the screw hole of the machine spindle end face must match).
2. Oil Path Tool Holder (External Coolant to Internal Coolant Tool Holder)
a. Install the fixing block on the machine end face and connect the water inlet pipe to the positioning block.
b. Oil path tool holder (external coolant to internal coolant tool holder) installation: first loosen the M6 thread on the positioning key so that the positioning column can move freely up and down (there is a spring under the positioning column), and then position the ring on

Mold Manufacturing: Frequently Asked QuestionsWhen selecting mold steel, what are the most important and decisive factors?
Forming method - Two basic types of materials can be chosen.
A) Hot work tool steel, which can withstand relatively high temperatures during mold casting, forging, and extrusion.
B) Cold work tool steel, which is used for blanking and shearing, cold forming, cold extrusion, cold forging, and powder pressing forming.
Plastics - Some plastics can produce corrosive by-products, such as PVC plastic.
Factors such as condensation caused by long periods of downtime, corrosive gases, acids, cooling/heating, water, or storage conditions can also lead to corrosion.
In these cases, mold steel made of stainless steel is recommended.
Mold size - Large-sized molds often use pre-hardened steel. Through-hardened steel is often used for small-sized molds.
