What This Machine Does
The C9350C and C9370C skim medium and small brake discs and drums back to a true running surface, which is what removes judder and restores even pad contact without replacing the part. Three spindle speeds are set by moving the belt position, and the spindle feed is infinitely variable with feeding capacity adjustable anywhere between 0.05 and 0.5, so a roughing pass and a fine finish cut are both available without changing gears. Feeding is by mechanical transmission, which is what gives the drive its working life in a busy brake shop. The main casting is aluminium alloy, so the whole machine is light for its capacity and can be moved into position in a workshop. Variable speed gears are made from 38CrMoAl alloy steel. The machine comes with moulds and clamps covering cars and light trucks, so it suits a shop that sees many vehicle types rather than one fleet.
Why Buyers Choose This Machine
- Skims discs and drums back to true so judder and uneven pad contact are cured without new parts
- Infinitely variable spindle feed adjustable from 0.05 to 0.5 covers roughing and finishing on one setup
- Three spindle speeds set by belt position so speed matches disc or drum diameter
- Mechanical feeding transmission is built for a long working life in a production brake shop
- Aluminium alloy main casting keeps the whole machine light and movable
- 38CrMoAl alloy steel variable speed gears in the drive train
- Clamps and moulds supplied for cars and light trucks so many vehicle types are covered
Where Drum and Disc Brake Cutting Lathe Machine C9350C Earns Its Place
Problems It Solves
- A scored or warped disc causes judder that no pad change will fix
- Replacing every marked disc and drum is far more expensive than skimming them
- Fixed feed rates force a compromise between cut rate and surface finish
- Machines without a clamp and mould set will not mount the range of hubs a shop sees
- Heavy brake lathes are difficult to reposition in a small workshop
Who It Is For
- Brake and general automotive repair workshops
- Tyre and fast-fit service centres adding brake machining
- Light truck fleet workshops servicing their own brakes
- Distributors supplying vehicle service equipment in export markets
Application Scenarios
- Skimming a brake disc that is causing pedal judder
- Machining a scored brake drum back to a clean bore
- Truing new discs that run out after fitting
- Brake service work across mixed car and light truck models
- Routine brake reconditioning in a general repair workshop

- Surface finish checked on a test disc after a finishing pass
- Feed adjustment verified across the 0.05 to 0.5 range
- Belt speed positions checked for correct engagement on all three steps
- Machine run in and a sample disc and drum machined before packing
Customisation Options
- C9350C or C9370C selected from the disc and drum sizes you work on

- Manual prepared in your working language
How It Compares With the Alternatives
| Brake drum and disc lathe machine T8445 / T8465 | The T8465 uses a twin perpendicular spindle layout for work from mini cars up to heavy trucks; the C9350C and C9370C are the lighter machines for medium and small discs and drums |
|---|---|
| Replacing discs and drums | Skimming restores a true surface on a part that still has material left, which is a fraction of the cost of new discs on every brake job |
| On-car brake lathes | An on-car lathe avoids removing the hub but this bench machine gives three spindle speeds and a full 0.05 to 0.5 feed range for both roughing and finishing |
Running the Machine
Step 1
Check the disc or drum thickness against its service limit before machining
Step 2
Mount the part with the correct clamp and mould for the hub type
Step 3
Set the spindle speed by moving the belt to one of the three positions
Step 4
Set a coarse feed within the 0.05 to 0.5 range for the first pass
Step 5
Take a light cut and confirm the tool is picking up across the whole surface
Step 6
Reduce the feed for the finishing pass
Step 7
Measure the finished thickness and deburr before refitting

Questions About Drum and Disc Brake Cutting Lathe Machine C9
What is the difference between C9350C and C9370C?
They cover different disc and drum sizes within the medium and small range. Send us the largest disc and drum diameter you machine and we will confirm the model.
How is the spindle speed changed?
Three spindle speeds are available and are selected by changing the belt position.
What feed range does it give?
The spindle feed is infinitely variable and the feeding capacity is adjustable from 0.05 to 0.5, so you set roughing and finishing feeds directly.
Will the clamps fit the vehicles in my market?
The machine comes with moulds and clamps for cars and light trucks covering many vehicle types. Send us the hub types you see most and we will confirm the adaptor set.
Why is the casting aluminium alloy?
The main casting is aluminium alloy, which keeps the whole machine light so it can be moved and positioned in a workshop.
What are your payment and trade 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.
What consumables will I need?
Cutting tips are the running consumable. Tell us your monthly brake volume and we will propose a starting quantity.
