Transportation:

The table and wheelhead are fixed with red pressed plate before transportation to avoid any damage .It must to remove all these red plates before operate machine

The wires outside the electrical cabinet and control are covered in flexible conduit for protect from any damage ,and there is oil in auto-lubrication system

Before lifting the machine ,prepare an adequate cable .Hook the cable unto the eye-bolts fixed at base .Please take a note of the following items while lift machine.

1. The cable must be capable of lifting weight more than 2 tons.

2. Place wooden wedge or rags between cable & machine to prevent the machine from

damage.

3. Lifting cable must be strong enough with diameter over 10mm.

4. Table must be truly fastened to avoid any slip during movement

Machine Transportation & Installation

Cleaning:

All sideways and ground surface are coated with anti-rust preventive before

delivery .Remove the coating with solvent agent prior to operation.

Installations:

While doing the installation ,special cares must be paid to the followings:

1. Never install the machine at an area where has direct sun light to maintain a

longer life ,preferable at an area has constant temperature.

2. Never install the machine at an area where is dusty ,not at an area next to

high-shocking machines ,such as ,air compressor ,press machine ,etc.

3. Machine is supplied with leveling and blocks as standard to facilitate and to avoid

any vibration.

Leveling:

It is essential to level the machine before operation . Please take a note of the following

items while leveling.

1. Prepare a level having the sensitivity of 0.02 mm/M( or 0.0002〞/ 10〞).

2. Clean the table surface before leveling .

3. Adjust the level as Figure indicates to place level.

4. After checking the table ,check torsion by traversing the table to left and right to

check if the table is distorted.

5. Check leveling which may be varied due to work load and others in 30 days after

installation .And check semiannually afterwards to retain grinding accuracy.

Electrical Power & Motors

Electrical equipment:

Rotation of motors:

Check the rotation of motors in details before operating the machine .

Wheelhead motor: The grinding wheel should rotate inward in the operator’s

Workhead motor: The tipped center should rotate inward in the operator’s

Coolant pump : Clockwise ( CW )

Table travel motor : Push up the button “TABLE AUTO MANUAL”, then push the button “TABLE LEFT” or “TABLE

Note:

The rotation of motors are checked in the plant before delivery. In case any of the motors

run in opposite direction ,just switch any of the “R/S/T” cables in the electrical cabinet .

In case there are more than 2 motors run in opposite direction, a cable change from the Individual motor connection is required.

Check the machine voltage with power source before connection. And check the

rotation of motors before operation.

direction.(Clockwise CW)

RIGHT” .Check the table if move on the correct direction.

Lubrications System & Coolant System

Lubrication system :

Coolant system :

Recommended coolants :

material finish and wheel’s life .

There is an automatic lubrication supplied as standard for lubrication on all

slideways .The volume of the unit of 1 liter ( 2 liters for OD-820 Models)

The volume of coolant tank is of 72 liters . Just hook up the pipe to the coolant

nozzle before connecting power .

An appropriate coolant is essential for precision grinding ,and is resulted in the

A. Purpose of using coolant system.

a. Refrain material from temperature rise. b. Flush off the grinding dust & peel-off grains. c. Lubrication the material.

B. Category of coolant system.

a. Soluble coolant : Mainly with non-organic solution ,mostly suitable for

cast iron ,cast steel grindings .

1. Emulsion type

2. Soluble solution type

3. Solution type

b. Non-soluble coolant: A coolant with mineral oil in sulfuric

objects, suitable for lubrication.

Table traverse and adjustment

The table can be driven both by manual and mechanical :

1. Manual traverse : Release the AUTO/MANUAL operating knob at the clutch

gear from the clutch unit. Swivel the handwheel to drive table manually.

2. Motorized auto drive : Adjust the table travel limit dogs to a desired

position. Tighten the AUTO/MANUAL operation knob at the table handwheel to engage the clutch gear with the clutch unit .Push the “TABLE RIGHT” or “TABLE LEFT” movement buttons to drive table automatically .The table’s speed is variable that can be altered by Digital Variable Speed (DVS)System .

Adjustment of table inclination

The table consists of top & bottom slides in which the top slid is adjustable as foloows:

1. Release the two hex bolts at both table ends .

2. Pull up the knob .

3. Turn the adjusting knob in conjunction of the indicator to desired angle .

4. Tighten the two hex bolts at both table ends then begin grinding .
