What This Machine Does
The 3MB9808 is a portable vertical honing machine for the inner holes of mechanical parts, with a processing range of 40 to 82 mm and a maximum honing length of 200 mm. It is aimed at the holes of cylinders and hydraulic cylinders on motorcycles, automobiles, tractors and pneumatic tools. Honing improves both the surface roughness and the dimensional tolerance of a bore, which is why a bored or reamed hole is finished here rather than left as machined. The machine is built as a simple press with only five functional components for operation, and a new worker can be taught to run it in one to two hours. Once the honing depth is set on the first piece, the main spindle mechanism does not need changing for the rest of the lot, so a batch runs at a fixed setup. At 450 kg and 1190 x 380 x 2070 mm it is a compact machine that a small workshop can install without rebuilding the floor plan.
Why Buyers Choose This Machine
- Hones 40 to 82 mm bores to a maximum length of 200 mm, covering motorcycle and small cylinder work
- Improves both surface roughness and dimensional tolerance of a bored hole
- Only five functional components to operate, so a new worker is productive in one to two hours
- Honing depth set once on the first piece then held for the whole lot without changing the spindle mechanism
- Suits engine cylinders and hydraulic cylinders as well as pneumatic tool bores
- 450 kg machine weight and 1190 x 380 x 2070 mm footprint fit a small workshop
- Portable press format rather than a full production honing line
Where Vertical Cylinder Honing Machine 3MB9808 Earns Its Place
Problems It Solves
- A bored hole left as machined has the wrong surface roughness for a sliding seal or a piston ring
- Dimensional tolerance after boring is often not close enough for a hydraulic fit
- Complicated honing machines take too long to teach in a small shop
- Resetting depth on every part of a batch wastes time and gives inconsistent results
- A full-size honing machine is more floor space than a small workshop can spare
Who It Is For
- Motorcycle and small engine repair workshops
- Hydraulic cylinder repair shops finishing bores after machining
- General machine shops honing inner holes of mechanical parts
- Distributors supplying small honing equipment to repair workshops
Application Scenarios
- Honing motorcycle cylinder bores after reboring
- Finishing hydraulic cylinder bores on repaired rams
- Honing pneumatic tool bores to improve surface roughness
- Batch honing of mechanical part inner holes at a fixed depth setting
- Small tractor and automobile cylinder finishing in a general repair shop

How It Compares With the Alternatives
| XAIMC 3MB9817 vertical cylinder honing machine | The 3MB9817 hones 25 to 170 mm to 320 mm depth with four spindle speeds and a tilting fixture; the 3MB9808 is the compact 40 to 82 mm 200 mm machine for small bores |
|---|---|
| XAIMC VHM170 automatic honing machine | The VHM170 is a CNC machine with stepless spindle and stroke control for production honing; the 3MB9808 is a manual press that a new worker can run within two hours |
| Leaving a bore as machined | Boring sets the size but leaves the surface as cut; honing improves both the surface roughness and the dimensional tolerance of the hole |
Running the Machine
Step 1
Confirm the bore is within the 40 to 82 mm range and no longer than 200 mm
Step 2
Fit honing stones suited to the bore diameter and material
Step 3
Set the honing depth on the first piece
Step 4
Hone the first piece and check bore size and surface finish
Step 5
Run the rest of the lot without changing the main spindle mechanism
Step 6
Check bores periodically through the batch
Step 7
Replace stones as they wear and re-check the first piece after each change

Questions About Vertical Cylinder Honing Machine 3MB9808
What bore sizes will it hone?
40 to 82 mm diameter to a maximum honing length of 200 mm. For larger bores look at our 3MB9817, which covers 25 to 170 mm to 320 mm depth.
How long does it take to train an operator?
The machine has only five functional components for operation and a new worker can learn to run it within one to two hours.
Can it hone hydraulic cylinders?
Yes. It is suitable for honing the holes of cylinders and hydraulic cylinders of motorcycles automobiles tractors and pneumatic tools, and for inner holes of other mechanical parts.
Do I have to reset the machine for every part in a batch?
No. Once the honing depth of the first piece is properly adjusted the main spindle mechanism does not need to be changed for the rest of the lot.
How heavy is the machine and how much space does it need?
450 kg, with dimensions of 1190 x 380 x 2070 mm.
What voltage is it supplied at?
We set supply voltage and frequency to your market. Confirm your shop supply when you place the order.
What are your payment and trade terms?
