All-in-One Boring & Honing Design Saves Workshop Cost & Space
This vertical honing machine combines cylinder boring and honing into a single unit, eliminating the need to purchase separate boring and honing equipment. It streamlines cylinder reconditioning workflows, cuts equipment investment, and occupies less floor space for engine rebuilding shops. It restores worn cylinder bores, delivers standard cross-hatch finish, and perfectly matches cylinder sleeve replacement overhaul jobs.
Advanced 0-50° Rotatable Worktable for V-Type Cylinder Block Machining
Fitted with the market-leading rotatable worktable adjustable from 0° to 50°, the machine easily handles V-shaped engine blocks that ordinary honing equipment cannot process. The cylinder block clamping mechanism provides safe, fast and stable fixation. Worktable vertical lifting is controlled by handwheel, allowing technicians to adjust workpiece height flexibly for comfortable processing.
Air Cushion Spindle Slide & Flexible In-Process Honing Adjustment
The spindle head moves smoothly longitudinally and horizontally on air cushion plates and locks firmly at any position. Operators can adjust honing head expansion freely during machining at any time. It supports two point grinding modes: free manual point grinding and stroke bump controlled point grinding, enabling targeted correction of local bore deformation and uneven wear for ultra-precise cylinder geometry.
User-Friendly Operation & Wide Compatibility for Multiple Engine Types
Intuitive control layout with simple operation, new technicians can master the machine quickly without complicated training. It adapts to gasoline, diesel, heavy truck, agricultural machinery, marine and industrial power engine cylinders. Built with rigid stable structure and reliable spindle system, it is ideal equipment for engine remanufacturing factories, automotive machine shops, fleet repair centers and vocational training workshops.

FAQ
1 Why does the TH170D combine both boring and honing in one machine?
The TH170D integrates cylinder boring and honing into a single unit, allowing workshops to bore cylinders to the desired oversize and then immediately hone them to the correct crosshatch finish and final diameter — all on one machine. This eliminates the need for separate boring and honing stations, saves floor space, reduces equipment cost, and streamlines the engine rebuilding workflow.
2 What engine types is the TH170D compatible with?
The TH170D is compatible with a wide range of engine blocks, including passenger car engines, light truck engines, motorcycle engines, and small to medium diesel engines. Its adjustable boring range and versatile clamping system accommodate various cylinder bore sizes and block configurations commonly encountered in general engine rebuilding.
3 What are the advantages of a boring-and-honing combination machine over separate units?
A combination machine saves shop floor space, reduces total equipment investment, and simplifies the workflow by keeping the engine block on a single workstation. The operator can transition from boring to honing without moving the block between machines, which helps maintain alignment and reduces setup time, leading to faster job completion and higher throughput.
4 How does the TH170D ensure proper cylinder bore quality and finish?
The TH170D’s rigid spindle and precision feed system ensure accurate, straight cylinder boring, while the integrated honing unit produces the correct crosshatch pattern essential for proper piston ring seating and oil retention. Together, they deliver the bore geometry, surface finish, and dimensional accuracy required for professional engine rebuilding.
5 Is the TH170D suitable for small to medium engine rebuilding shops?
Yes. The TH170D is an ideal all-in-one solution for small to medium engine machine shops. Its compact footprint, dual functionality, and user-friendly controls make professional cylinder boring and honing accessible to shops that need versatile capabilities without the space or budget for multiple large, dedicated machines.
6 If the machine breaks down, how do you provide after-sales support? Do you provide operation videos?
Yes. We provide comprehensive after-sales support, including remote technical assistance, online troubleshooting, operation manuals, demonstration videos, maintenance tutorials, and live video guidance. If replacement parts are required, genuine spare parts can be supplied quickly to minimize downtime and keep your machine running efficiently.
7 Can you issue Certificates of Origin (CO), Form A, Form E, or other export documents?
Yes. We can provide the necessary export documents — including Certificates of Origin (CO) and other preferential certificates such as Form E — in accordance with the trade agreements and customs requirements of the destination country. We can also assist you in preparing commercial invoices, packing lists, bills of lading, and other export documentation.
8 What is your minimum order quantity (MOQ)? Do you support OEM & ODM customization?
Our standard MOQ is 1 machine for most models. We also provide OEM and ODM services for distributors and equipment brands, including custom logos, machine colors, nameplates, voltage, packaging, and other specifications to meet your market requirements.
9 Which shipping ports do you use? Can you deliver to my designated warehouse?
We typically ship from major Chinese ports, including Shenzhen, Guangzhou, Ningbo, and Shanghai. We can also arrange delivery to your designated warehouse, freight forwarder, or project site through flexible international shipping solutions.
10 How long does delivery take to my country?
Production typically takes 7-35 days, depending on the machine model and order quantity. Shipping time varies by destination and transportation method. Once your order is confirmed, we will provide a detailed production schedule and estimated delivery time.
