Precautions 1. This instruction manual describes model C1FB Rotating Hydraulic Cylinder Standard Model. 2. Please read this manual carefully and fully understand the procedures for installation, operation, inspection, and maintenance before operating the rotating cylinder. 3. Ignoring any instructions in this manual may result in a serious accident or machine damage, leading to injury to the operator or personnel near the machine.
Safety Precautions Read and understand the following precautions before using the rotating cylinder, and observe them during operation. DANGER Never turn off the power of the hydraulic pump during spindle rotation. Danger by discharge of workpiece. Never operate the selector valve during spindle rotation. Danger by discharge of workpiece.

Use a strainer with 20 µm filterability or better. Order all parts for this rotating cylinder from Howa machinery, Ltd. Howa assumes no responsibility for accidents which occur when other than Howa genuine parts are used. Any and all warranties are void unless only Howa genuine parts are used.
Model C1FB has a built-in check valve to prevent a sudden drop in internal pressure if a problem occurs in the hydraulic system during spindle rotation. The check valve is mounted in the distributor shaft so the internal pressure can be retained regardless of oil leakage from the drain port.
3. Installation The rear end of the spindle to which the rotating cylinder is attached has various configurations. Here, a typical rear end configuration is shown as an example. 3.1 Cylinder Adaptor Determine the location for the rotating cylinder, with interference with the lathe body, direction and position of piping, draft and other necessary factors taken into account.
3.3 Mounting and Anti-rolling Guide What is most important in accomplishing the piping work is that the rotating cylinder must be protected from excessive stress. The viscosity of the hydraulic oil will cause a slight amount of torque on CAUTION the distributor when the rotating cylinder rotates.
3.4 Piping Two hydraulic oil supply ports and one drain port are provided on the rotating cylinder distributor. These ports are indicated by the marking provided next to the port. The meaning of marked characters and the port type are shown below. Hydraulic oil supply port (Piston moves retract) Hydraulic oil supply port (Piston moves extend) Drain port...

3.6 Hydraulic Unit, Hydraulic Oil, Hydraulic Circuit When providing a dedicated pump unit for the hydraulic unit, determine the pump specifications by taking the cylinder size, permissible oil pressure, required gripping force, etc. into consideration. Do not use a motor with too much power or a pump with excessive delivery capacity, because the oil temperature will rise and this may cause problems.
If the piston movement direction is changed with the 4-port 2-position DANGER solenoid valve, design the hydraulic circuit so as to chuck even if the solenoid valve is demagnetized. Ignoring this instruction may result in the malfunction of the check valve and danger caused by discharging of the workpiece.
3.8 Trial Operation 1) Pour the hydraulic oil into the oil port to the upper limit of the oil level gage. 2) Set the hydraulic pressure to 0.5MPa or less, and check for abnormality in the rotating cylinder operation. Then, gradually raise the pressure to the maximum pressure while checking for oil leakage and abnormalities in each part.
4. Maintenance and Inspection 4.1 Check of Hydraulic Oil The bearing is cooled and lubricated with drain so that any special lubricating oil is not necessary as long as the hydraulic oil is clean. Therefore, for the sake of maintenance of this rotating cylinder, it is most important to keep the hydraulic oil clean at all times.
