  1. Prepare the duplex tubing:

  • Split the tubes apart on one end and connect them to the barbed outlet fittings on the canister.

Figure 7: Duplex tubing connected to the canister.

  • On the opposite end, separate the tubes approximately 5 in. back from the end.

  1. Identify which tube connects to the canister fitting labeled Cool. Trace that tube to the loose end and cut approximately 3 in. from the end. Set aside the removed section.

  2. Install the brass check valve onto the tube connected to the Cool fitting. Make sure that the arrow on the valve points away from the canister.

  1. Install the removed tubing section onto the other end of the check valve.

  2. Trim the longer of the two tubes so that both tubes are equal in length.

  1. You've completed the assembly of the Lube Cube. Go to "Install the Lube Cube on the Machine".

Install the Lube Cube on the Machine

Depending on which machine you're installing the Lube Cube on, the installation varies.

1100M, 1100MX, 770M, and 770MX (MF Serial Number) Mills

IMPORTANT! This kit isn't compatible with 770MX mills sold after December 2025 (with serial numbers beginning with ML).

  1. On the back of the chip pan below the electrical cabinet, locate the two threaded M5 holes. Mount the canister to the chip pan using two M5 button head cap screws.

Figure 15: Lube Cube mounted on the back of the chip pan.

  1. Route the solenoid power cable to the outside of the electrical cabinet, and connect it to the Coolant Pump Power outlet.

  2. Unthread the magnetic base from the bottom of the flow control block. Then, route the flow control block underneath the electrical cabinet and into the enclosure.

  3. Reinstall the threaded magnetic base into the flow control block.

  4. Mount the flow control block to the machine table or the spindle head sheet metal using the magnetic base.

  5. You've completed the installation of the Lube Cube on your machine. Go to "Make Air Connections".

PCNC 440 Mills

  1. Hang the canister onto the back of the chip pan using the solenoid mounting bracket.

  2. Route the loose end of the solenoid power cable to the electrical cabinet, and plug it into the cord end.

  1. Route the flow control block and the magnetic base underneath the electrical cabinet and into the enclosure.

  2. Mount the flow control block to the machine table or the spindle head sheet metal using the magnetic base.

  3. You've completed the installation of the Lube Cube on your machine. Go to "Make Air Connections".

PCNC 1100 and PCNC 770 Mills

  1. Hang the canister onto the back of the chip pan using the solenoid mounting bracket.

  2. Route the loose end of the solenoid power cable to the power connection panel (under the electrical cabinet), and plug it into the Coolant outlet.

  1. Route the flow control block and the magnetic base underneath the electrical cabinet and into the enclosure.

  2. Mount the flow control block to the machine table or the spindle head sheet metal using the magnetic base.

  3. You've completed the installation of the Lube Cube on your machine. Go to "Make Air Connections".

Make Air Connections

NOTE: The Lube Cube is designed to operate at high volume and low pressure (10–30 psi), consuming approximately 0.7–2.0 cfm.

  1. Locate the air supply line from your compressor.

  2. Use the tee fitting installed on the 1/4 in. black tubing to splice into the air supply line.
