1. Cleaning the coolant joint section.

Section (E) may become clogged with chips which are contained in the coolant. The coolant will then leak from section (E) during clamping and thus the amount of injection onto the workpiece will decrease.

In that case, after unclamping the turret, clean section (E) using an air gun. If the situation does not improve, replace the coolant bushing. Also, clean section (E) at fixed periods (about once a month) using an air gun.

2. Replacing the coolant bushing. Use the following procedure to replace the coolant bushing of the turret:

[2] Remove C and D using the pull-out jig contained in the tool box. (Refer to Figure 5-15)

(a) Insert the bolt into the hole of the block, and then screw the bolt into the threaded section of the end of C.

(b) Tap the nut section of the bolt using the block to remove C.

(c) Then, remove D using a similar method to that described at sub-steps (a) and (b) above.

Warning: Chips, dust, and foreign matter inside the electrical control cabinet will cause problems. Always keep the electrical control cabinet clean. Do not use air gun to clean.

Caution: Put the filter in place after it has dried naturally.

Is the air filter contaminated?

If the air filter is contaminated, remove the filter from the cabinet and wash it with water.

Adjust the total thickness of the shims if the tailstock requires readjustment for vertical alignment. The tailstock is preadjusted by gauge grinding of the shims prior to shipping.

[1] Set plate ” on the slideway and press the plate against surface G of the bed (that is, set the tailstock base to its reference position).

[2] Tighten hex socket head bolts ‘ (to move the base of the tailstock to the rear).

[3] Hand-tighten hex socket head bolts “ (to set the tailstock base on the bed).

[4] Measure the degree of parallelism between the carriage (Z-axis) and the sliding surface of the slideway. If the parallelism is not good enough, laterally move the tailstock base using hex socket head bolts ‘ (the maximum allowable amount of parallelism is 10 microns).

[5] After checking for accuracy, if no abnormalities are present, securely tighten hex socket head bolts “.

[6] Secure the rear end of the tailstock base using special bolt ’.

- Check for sounds of reaction during sensor contact.
