BULL NOSE CENTER TYPE LIVE CENTER

Features:

The center uses a combination of deep groove ball bearings and ball thrust bearings.
Suitable for medium-speed, precise processing of medium-load workpieces on CNC lathes.
The special umbrella-shaped structure at the head is designed for processing workpieces with central holes and pipes.
The head is made of alloy tool steel, with a hardness of HRC 60° ± 2° after heat treatment, ensuring high steel performance and wear resistance.
This center is intended solely for lathe processing. For use with cylindrical grinders, a high-precision bull-nose live center should be custom ordered.

CONSTANT HYDROSTARTER FACE DRIVER

Product Information:

The constant hydrostarter face driver is primarily used on forming lathes, CNC lathes, and standard lathes to process axis-type workpieces. With just one collet, you can complete all exterior dimensions of the workpiece. By using the workpiece’s center hole for positioning, high-quality results can be ensured.

The driver plate is propelled by three floating hydraulic cylinders, pressing firmly against the end of the workpiece to rotate it. Even if the end face and the axis are misaligned by up to 5 degrees, the constant face driver will still function normally.

The constant face driver is typically provided with the driving center body, along with interchangeable centers and driver plates. Please specify your requirements when placing an individual order. Additionally, we can manufacture custom interchangeable centers and driver plates upon request.

Mounting Instructions:

Selecting Components
Choose the appropriate center and driver plate based on the diameter of the workpiece.
Changing the Center
- Loosen the bolt to remove the old center.
- Insert the new center, ensuring that the bolt’s guide part aligns with the leading groove.
- Tighten the bolt. The center should now be able to move along the axis but remain non-rotational.
Changing the Driver Plate
- Insert the driver plate into the body (B), making sure the plate’s groove aligns with the thinner section of the piston.
- Gently lever the driver plate into place.
Adjusting the Center Length
- Use Piston 1 to adjust the length of the center.
- Ensure there is a gap of 3-7 mm between the center and the gear on the driver plate for optimal performance.
Fixing the Workpiece
- Secure one side of the center hole on the active center.
- Support the other side using the apex of the lathe.
- The power of the strut can be calculated with the following formula:
  $\cdot ob \cdot i$
  Where:
  - p = Power of the strut
  - t = Cutting depth (mm)
  - s = Rotational speed (revolutions per minute)
  - ob = Tensile strength of the material
  - i = Ratio derived from the workpiece dimensions (d/D as indicated in Figure 2)

Maintenance:

Lubrication
Ensure that there is sufficient 20# engine oil to lubricate the active center. Tighten the necessary components as needed.
Hydraulic Pressure Maintenance
If hydraulic pressure is low, follow these steps:
- Loosen the two screw caps on the seal.
- Add an appropriate amount of hyperbolic gear oil until the piston’s surface aligns with the main body.
- Tighten the sealing body bolts.
- If the washer in the sealing assembly is damaged, replace it immediately. The seal was pre-assembled at the factory, and normally, it should not be removed.
Recommended Cutting Range
- Maximum cutting depth: t = 5 mm
- Maximum cutting speed: s = 0.4 mm/turn
Easily Damaged Parts
- O-type Seal Ring: φ 16*2.4
- Combination Washer: Type B6

FIXED FACE DRIVER CENTER

Features:

The body and center shaft are made of alloy steel, treated with both heat and sub-zero processes. Hardness: HRC 60° ± 1°.
A driving dog is required for traditional lathe operations to prevent the workpiece from stopping. These work-driving centers feature a 6-teeth or 8-teeth design, eliminating the need for traditional driving dogs.
It supports the workpiece on the end surface, enabling easy setup and rapid machining.
The work-driving center is also suitable for use on gear hobbing machines.
