What This Machine Does
The 3M9735B is a vertical multi-angle surface grinding and milling machine for the joint faces of cylinder blocks and cylinder heads, from small and medium sizes up to large-size blocks. It is built for a shop that takes in a mixed workload rather than one engine family: the same machine grinds a car head one hour and faces a large block the next. The spindle runs on high precision bearings with the motor fixed at the back of the machine, so the spindle keeps its accuracy at high speed and the motor mass sits away from the cut. Plastic guideways keep travel stable and flexible, and the work table feed is steplessly adjustable, which is what makes the machine suitable for processing workpieces in different materials without changing the machine over. Two table widths are offered, 1300*500 mm and 1500*500 mm, with maximum working length 1300 mm or 1500 mm, working width 350 mm and working height 800 mm.
Why Buyers Choose This Machine
- Covers small medium and large cylinder blocks and heads on one machine instead of two
- Vertical multi-angle layout suits angled head and block faces as well as flat decks
- High precision spindle bearings with a rear-mounted motor keep spindle accuracy at high speed
- Plastic guideways give stable flexible table travel for both roughing and finishing
- Stepless table feed makes the machine suitable for workpieces in different materials
- Choice of 1300 mm or 1500 mm maximum working length sized to your heaviest job
- Grinding and milling on the same machine so heavy stock removal and finishing are both covered
Where Cylinder Block Grinding-Milling Machine 3M9735B Earns Its Place
Problems It Solves
- A shop needs two machines when one covers only small heads and the other only large blocks
- Distorted block and cover surfaces cause repeat gasket failure after rebuild
- Fixed table feeds force the same setting on soft cast iron and on harder repair material
- Angled head and cover faces are awkward on a machine with no multi-angle capability
- Spindle accuracy drops at high speed when the drive motor is hung on the spindle end
Who It Is For
- Engine rebuilders with a mixed workload of car and heavy-engine work
- Machine shops offering head and block resurfacing to local garages and fleets
- Fleet and plant workshops that recondition engines in-house
- Distributors equipping general engine rebuild workshops in export markets
Application Scenarios
- Resurfacing small and medium car cylinder heads in a general rebuild shop
- Facing large truck and plant engine blocks up to 1500 mm working length
- Multi-angle grinding of block and cover surfaces
- Milling a heavily distorted deck before a finish grinding pass
- Mixed subcontract resurfacing work across several engine families

How It Is Built and What Can Be Changed
Operations Performed
- Surface grinding
- Milling
- Multi-angle face machining
Quality Control
- Flatness checked on a ground test workpiece before shipment
- Spindle run-out measured on the high precision bearing assembly
- Table travel checked for straightness across the full 1300 mm or 1500 mm length
- Stepless feed tested through its range under cutting load
- Machine run in and sample face ground before crating
Customisation Options
- 3M9735B*130 or *150 selected from your maximum working length
- Fixtures specified for the block and head types you run
- Grinding wheel and milling cutter package chosen for your material mix
- Supply voltage and frequency set for your market
- Manual and machine labelling prepared in your working language
How It Compares With the Alternatives
| Cylinder block grinding & milling machine 3M9740B | The 3M9740B is aimed at the heaviest block work; the 3M9735B is the machine for a shop whose workload runs from small heads up to large blocks |
|---|---|
| TSM850 cylinder head grinding and milling machine | The TSM850 is a head-focused machine; the 3M9735B gives 800 mm working height and up to 1500 mm working length for large blocks |
| Sending resurfacing to a subcontractor | In-house resurfacing removes a transport leg and several days from every engine job and keeps the margin in your shop |
Running the Machine
Step 1
Clean the block or head and identify where the surface has gone out of true
Step 2
Clamp the part on the 1300*500 mm or 1500*500 mm table within the 800 mm height limit
Step 3
Set the head angle where the face you are machining is not flat to the table
Step 4
Choose milling for heavy stock removal and grinding for the finishing pass
Step 5
Set the stepless table feed to suit the workpiece material
Step 6
Take a light first pass and confirm the cut picks up over the whole face
Step 7
Finish to a clean face then measure flatness and wash the part before assembly

Questions About Cylinder Block Grinding-Milling Machine 3M97
What sizes of block and head does it take?
Worktable is 1300*500 mm or 1500*500 mm, with maximum working length 1300 mm or 1500 mm, working width 350 mm and working height 800 mm. Send us your largest block and we will confirm the version.
Can it grind and mill on the same machine?
Yes. It is a surface grinding and milling machine and is suitable for grinding and milling all kinds of cylinder body and cover surfaces.
What does multi-angle mean on this machine?
The vertical head arrangement lets you set the machine to angled block and cover surfaces, not only flat decks. Tell us the angles you work on and we will confirm the setup.
Will it handle different workpiece materials?
Yes. The work table feed is stepless, which is what makes the machine suitable for processing workpieces of different materials.
What is the lead time?
Lead time depends on the version, fixtures and voltage specified. Send us those details and we will confirm a shipment date with the quotation.
What are your trade and payment terms?
FOB CFR and CIF. Payment is 30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
Do you supply spare parts after delivery?
