Engine Rebuild & Machine Shop Software: Cylinder Bore Micrometer Sheets & Crankshaft Grinding

CarsKeep for Engine Rebuilders and Automotive Machine Shops digitizes precision engineering operations: electronic cylinder bore micrometer measurement sheets (taper, out-of-round ovality, and piston-to-wall clearance down to 0.01 mm), cylinder head hot-water pressure test logs at 6 bar, integrated oversize piston (+0.25 / +0.50 mm) inventory ordering, and a streamlined B2B sublet portal for partner automotive repair shops.

Problems this module solves

#1

Lost paper measurement scraps from dial bore gauges

Machinists jot bore measurements on oily cardboard gasket boxes. Scraps get smudged and lost, while vehicle owners demand formal precision dimensional certificates.

Решение CarsKeep

Digital measurement sheets in CarsKeep. Machinists log dial gauge readings on mobile; the software calculates taper and out-of-round ovality, highlights tolerances in red, and generates PDF reports.

#2

Costly ordering mistakes for oversize pistons and bearings

Machinist bores an engine block to 82.50 mm (+0.50), while the parts department orders standard 82.00 mm pistons, creating idle machines, missed deadlines, and tied-up cash.

Решение CarsKeep

Direct synchronization between bore sheets and parts ordering. The system automatically populates supplier purchase orders with the exact oversize spec (+0.25 or +0.50 mm) including specified piston clearance.

#3

'You ruined my crankshaft': unwarranted customer lawsuits

A customer brings in a cylinder block for resurfacing; after engine assembly, the motor seizes and the customer blames the machine shop for improper grinding.

Решение CarsKeep

Machining Certificate of Conformance. Document precise before-and-after micrometer measurements, dial indicator runout values, and capture electronic customer signatures upon pickup.

#4

Chaotic billing for B2B sublet machining work

The machine shop machines cylinder blocks for 20 independent auto repair facilities. Work orders tracked in handwritten notebooks result in lost invoices and late collections.

Решение CarsKeep

B2B sublet machining portal. Store wholesale discount pricing tiers, send automated WhatsApp notifications when machining finishes, and reconcile monthly billing in 1 click.

How it works in practice

1

Intake, Ultrasonic Wash & Inspection

Degrease bare engine block, inspect main bearing journals, and take preliminary 3-step dial bore gauge measurements.

2

Pressure & Crack Testing

Submerge cylinder head in 75°C heated water bath under 6.0 bar air pressure to locate hairline water jacket fractures.

3

Precision Machining Operations

Execute cylinder boring, plateau honing, cylinder sleeving, crankshaft journal grinding, and deck resurfacing.

4

Quality Control & Delivery

Verify final piston-to-cylinder clearances, print digital Engine Machining Passport, and rust-proof the finished engine block.

Specialized Engineering Management Software for Engine Machine Shops & Rebuilders

Internal combustion engine rebuilding and high-precision automotive machining require uncompromising dimensional accuracy. Guesswork in calculating piston-to-cylinder clearance, lost notes on oily cardboard boxes, and chaotic ledger accounting for B2B sublet machining jobs inevitably lead to catastrophic engine failures and expensive warranty disputes.

CarsKeep Engine equips machinists and engine builders with digital micrometer measurement cards, pressure testing logs, and automated oversize parts synchronization.

Core Capabilities Built for Engine Machine Shops:

  1. Digital Dial Bore Gauge Measurement Sheets:
    Log top, middle, and bottom cylinder dimensions across thrust and axial planes from mobile. The system calculates taper and ovality automatically to select optimal piston sizes.

  2. Crankshaft Journal Grinding & Cylinder Head Testing:
    Document runout on V-blocks, journal dimensions before and after grinding, deck resurfacing depth, and 6-bar hot-bath pressure test outcomes.

  3. Synchronized Oversize Parts Procurement:
    Prevent expensive parts ordering blunders by automatically syncing target bore dimensions (+0.25 / +0.50 mm) with warehouse piston, ring, and bearing inventory.

  4. Engine Machining Passport with Legal Sign-Off:
    Generate detailed PDF engineering certificates with exact machine tolerances, shielding your shop from unwarranted post-assembly engine failure liability.

  5. Wholesale Sublet Machining Portal for B2B Partners:
    Manage machining jobs received from independent garages with trade pricing, batch invoicing, and WhatsApp readiness notifications.

Frequently Asked Questions

Can cylinder bore measurement charts be sent directly to customers via WhatsApp from the machinist's phone? ▼

Yes. As soon as the technician records dial bore readings on their smartphone, CarsKeep generates an interactive visual graph of cylinder geometry with recommended repair dimensions (+0.25, +0.50, or resleeving) and sends a WhatsApp estimate approval link.

Is CarsKeep compatible with CNC machining centers and dynamic crankshaft balancing rigs? ▼

Yes. Work orders accommodate residual crankshaft unbalance readings measured in gram-millimeters (g·mm) with the flywheel and pressure plate attached, and allow attaching CNC G-code program files.

How does the system handle wholesale pricing and credit limits for partner repair shops? ▼

In the B2B customer profile, you can configure dedicated wholesale labor rate matrices (e.g. 20% discount on boring) and credit limits, producing consolidated monthly itemized statements in one click.
