A plate launcher is specialized equipment, without which it is impossible to imagine professional tire fitting or wheel balancing. It allows you to accurately center the disk on the machine shaft, eliminating runout and vibration during further processing. But how not to make a mistake when choosing among dozens of models? And what operating nuances do only experienced craftsmen know?
Many car owners are faced with a problem: after replacing wheels themselves or repairing rims at a service station, vibration appears at speed. In 80% of cases, the reason lies in incorrect centering of the disk on the machine - and this directly depends on the quality and settings plate launching machines. In this article, we will look at how the equipment works, what to look for when purchasing, and what errors lead to defective work.
A special feature of modern machines is their compatibility with discs of different diameters and types of fasteners. But even expensive equipment does not guarantee an ideal result if the installation technology is not followed. For example, Hofmann Geodyna 6000 or Corghi Artiglio Master require regular calibration, otherwise the centering error can reach 0.3 mm - a critical value for high-speed tires.
In garage conditions, simplified models like Bosal WBA-50 or Ravaglioli Tire Changer>. They are cheaper, but have limitations on maximum disk diameter and accuracy. We analyzed reviews from experts and compiled a rating of equipment based on price/quality ratio, and also collected instructions that will help you avoid common mistakes.
How the machine for launching plates works: principle of operation and device
The main task of the equipment is to firmly fix the wheel rim on the shaft of the tire changing machine, ensuring alignment with the axis of rotation. This is achieved by centering cone and clamping mechanism, which can be pneumatic, hydraulic or mechanical.
The process of launching a plate takes place in several stages:
- Installing the disc onto the machine's support platform.
- Centering using a cone that fits into the central hole of the disk.
- Fixation clamping jaws or collet mechanism.
- Checking runout using an indicator (in professional models - automatically).
In budget models, centering is done manually, which requires experience. For example, in Bosch TC 330 the master must independently adjust the position of the cone, whereas in Hunter GSP9700 this process is automated using a laser sensor.
Key parameter - centering accuracy. For professional machines it is ±0.05 mm, for households - up to ±0.2 mm. Exceeding this value leads to wheel imbalance, which manifests itself as steering wheel vibration at speeds above 80 km/h.
Types of plate launching machines: comparison of designs
All equipment can be divided into three categories according to the type of drive and fixation mechanism. Each has its pros and cons, which are important to consider when choosing.

Pneumatic models are optimal for garage use - they provide a balance between price and quality. For example, Sicam Tire Pilot or Giuliano Evo 2> allow you to work with discs up to 24 inches and have an error of no more than 0.1 mm.
Professional auto repair shops usually choose hydraulic or automatic machines. For example, Hunter GSP9700 equipped with a system 3D disk scanning, which compensates for deformation and wear of holes.
⚠️ Attention: When working with alloy wheels, do not use mechanical machines with metal clamps - they can damage the paintwork. For such cases, models with plastic or rubber linings are suitable, for example, Corghi Artiglio Master.
Selection criteria: what to look for before purchasing
When choosing a machine for launching plates, consider not only the price, but also the technical parameters that directly affect the quality of tire mounting.
- 🔧 Maximum disc diameter: For passenger cars 17–20 inches is enough, for SUVs and commercial vehicles - from 22 inches.
- 🎯 Centering accuracy: Optimally - no more than 0.1 mm. Check this parameter in the equipment passport.
- ⚡ Drive type: Pneumatics are suitable for service stations, mechanics - for garages.
- 🔄 Versatility of fastenings: Ability to work with discs of different PCD (bolt patterns) and central holes.
- 🛠️ Presence of runout indicator: Allows you to quickly check the quality of the installation.
Please note cone material. In cheap models, it is often made of soft metal that wears out quickly. The best option is hardened steel with an anti-corrosion coating.
Also check compatibility with your tire changer. For example, cars Hofmann and Corghi require special adapters for attachment to machines of other brands.

Step-by-step instructions: how to properly launch a plate
Even the most expensive machine will not produce results if the installation technology is broken. Follow this algorithm to avoid wheel runout:
- Clean the disk from dirt and corrosion, especially in the area of the central hole. Use a wire brush or a special cleaner (for example, WD-40 Specialist).
- Check the condition of the cone machines - it must be clean, without burrs. If necessary, wipe it with a cloth soaked in solvent.
- Install the disk onto the support platform, aligning the central hole with the cone. For alloy wheels, use protective pads.
- Secure the disc clamping mechanism. In pneumatic models, the pressure must be at least
6 bar. - Check runout using the indicator. Acceptable value - no more
0.15 mmfor passenger cars and0.25 mmfor freight. - Lock the position a locking bolt (if provided by the design).
A mistake many beginners make is not tightening the clamps enough. This causes the disc to move during balancing. In pneumatic models, the pressure is checked with a pressure gauge, in mechanical models - with a torque wrench (the tightening torque is indicated in the instructions).
After installation, be sure to check alignment of the disk and the machine shaft. To do this use laser pointer or a special template. If the displacement exceeds 0.2 mm, repeat the centering procedure.
⚠️ Attention: Never use a plate launcher with a damaged cone! Even a small dent on the surface of the cone leads to a displacement of the disk by 0.3–0.5 mm, which is guaranteed to cause vibration when moving.
What to do if the disk is not centered?
If the disk "walks" on the cone, check:
1. Condition of the central hole of the disk - it could have been deformed during the previous tire installation.
2. Cleanliness of the cone - even small chips can prevent a tight fit.
3. Correspondence between the diameter of the cone and the hole of the disk. For non-standard disks (for example, with a larger central hole), use adapter rings.
If the problem persists, try another cone or contact a service to diagnose the equipment.
Common mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to marriage. Here are the most common of them:
- 🔴 Ignoring Disk Cleanup. Dust or rust in the central hole moves the disk relative to the axis by 0.2–0.5 mm.
- 🔴 Wrong choice of cone. For example, using a cone to
PCD 4×100on disk withPCD 5×112. - 🔴 Over-tightening of clamps. This deforms thin-walled alloy wheels.
- 🔴 Operation without run-out check. Even a visually straight disc can have hidden deformations.
- 🔴 Using worn adapters. For example, adapter rings with play.
One of the most insidious mistakes is failure to take into account thermal expansion. If the disc has just been removed from the car (for example, after a long trip), its center hole may be slightly deformed due to heat. In this case, before starting the plate, you need to let the disk cool for 15–20 minutes.
Another nuance is working with forged wheels. They have a more rigid structure than cast ones, and therefore require an increased tightening torque (20–30% higher than standard). For example, for BBS CH-R recommended moment - 140 Nm, whereas for stamped discs it is enough 90–110 Nm.
Always check the calibration of the equipment before starting work! In professional models (for example, Hunter GSP9700) this is done automatically when turned on; in budget ones, manual configuration is required using a standard.
Maintenance and repair: how to extend the life of equipment
Regular maintenance of the plate launcher avoids breakdowns and maintains centering accuracy. Here is the minimum set of procedures:
- 🛠️ Weekly: cleaning the cone and clamping mechanisms from metal shavings and dirt. Use compressed air and a rag.
- 🛠️ Monthly: checking the pressure in the pneumatic system (must be
6–8 bar). Lubricate moving parts (use LIQUI MOLY LM 50). - 🛠️ Every 6 months: Calibrate the runout indicator. To do this, use a reference disk with known parameters.
- 🛠️ Once a year: replacement of worn parts (springs, seals, clamping jaws).
The most common breakdown is cone wear. Its surface becomes scratched over time, which impairs centering. You can restore the cone on a lathe, but it is better to replace it with a new one (cost - from 3,000 to 15,000 rubles, depending on the model).
In pneumatic models it often fails pressure reducer. Signs of malfunction: unstable disk fixation or air leakage. Repairs cost 5,000–10,000 rubles, but if the machine is older than 5 years, it is more advisable to consider buying a new one.
Critical for hydraulic machines oil quality. Use only brands recommended by the manufacturer (for example, Shell Tellus S2 V 46 for Hofmann). An oil change is required every 2,000 operating hours or every 2 years.
FAQ: answers to frequently asked questions
Can the machine be used to launch motorcycle rims?
Yes, but a special adapter is required for small diameters (usually up to 12 inches). In most models (eg Corghi Artiglio Master) such adapters are included in the kit. However, the centering accuracy for motorcycle rims should be higher - no more ±0.05 mm, as they are more sensitive to imbalance.
Which cone should I choose for discs with an enlarged central hole (for example, after boring)?
For such cases use stepped cones or adapter rings. For example, a disc with a 72.6mm bore on a machine with a 66.6mm taper will require a 3mm thick ring. It is important that the ring is made of hardened steel and has minimal play (no more than 0.02 mm).
What to do if vibration remains after balancing?
There may be several reasons:
- Incorrect centering of the disc on the machine (check the runout with an indicator).
- Disc deformation (check for disk straightening machine).
- Poor balancing (repeat the procedure with other weights).
- Worn wheel bearing (vibration occurs even on new wheels).
Start by checking the alignment - this is the most common cause of the problem.
How much does it cost to rent a plate launcher?
The rental price depends on the model and region:
- Mechanical machine (for example, Bosch TC 330) - from 500 ₽/day.
- Pneumatic (for example, Sicam Tire Pilot) - from 1,200 ₽/day.
- Professional (for example, Hofmann Geodyna) - from 2,500 ₽/day.
For long-term rentals (from a month), many companies provide a discount of up to 30%. Check availability of equipment insurance!
Is it possible to make a machine for launching plates with your own hands?
Technically yes, but it's impractical. Homemade designs (for example, based on a lathe) have a centering error 0.5–1 mm, which is unacceptable for modern tires. In addition, they do not provide sufficient rigidity of fixation, which is dangerous at high speeds of the balancing machine. If your budget is limited, it is better to buy a used professional model (for example, Corghi Artiglio older than 5 years) - it will cost less than making a homemade product with comparable accuracy.
