Surface roughness of both boring and milling reaches Ra 0.8, delivering smooth, high-quality finishes essential for automotive and diesel engine remanufacturing.
Flexible Processing for Automotive and Diesel Engines
The BM160 supports machining applications for automotive engines, diesel engines, truck engines, and industrial power units. Its 300 × 850 mm milling area provides flexibility for different engine block surface repair requirements. A generous 400 × 1,100 mm work table size with 980 mm longitudinal traverse and 70 mm cross traverse accommodates a wide range of engine components, from compact car blocks to medium-duty truck cylinder heads.
Professional Equipment for Engine Rebuilding Workshops
Designed for continuous workshop operations, the BM160 features a rigid structure, stepless adjustable spindle speed from 50 – 780 RPM, and stable feeding control from 10 – 900 mm/min to improve machining efficiency and processing consistency. Dual rated torque settings deliver 96 N.m at 50 – 500 RPM and 75 N.m at 500 – 780 RPM, adapting to various cutting loads and material hardness in daily engine reconditioning tasks.
Advanced CNC Control & Servo Drive System
Equipped with the EasyTouch 3 Axis control system and a powerful 3 kW AC servo spindle motor, the BM160 delivers precise positioning and reliable cutting performance. Electric longitudinal table feeding (30 – 1,200 mm/min) and quick travel (1,200 mm/min) streamline setup and machining workflows, while a 550 mm spindle traverse and 0 – 700 mm distance from spindle end face to workpiece support versatile machining configurations for diverse engine repair scenarios.

FAQ
1 What machining operations can the BM160 perform?
The BM160 performs precision cylinder boring for engine blocks and surface milling for cylinder heads and blocks. It can bore cylinders to precise oversize dimensions and mill deck surfaces to a flat, smooth finish. This dual-function capability covers two of the most fundamental operations in professional engine rebuilding on a single compact machine.
2 What engine types is the BM160 suitable for?
The BM160 is designed for engine blocks and cylinder heads from passenger cars, light trucks, and motorcycles. Its adjustable workholding and variable speed spindle accommodate a variety of block sizes and materials, including cast iron and aluminum, making it a versatile solution for general automotive engine machine shops.
3 How does the BM160’s boring-and-milling combination compare to a standard boring-only machine?
Unlike a standard boring-only machine that requires a separate milling unit for deck surfacing, the BM160 combines both functions in one. This saves floor space, reduces equipment costs, and simplifies workflow by allowing the technician to bore cylinders and surface decks on the same machine without moving the workpiece between stations.
4 How does the BM160 ensure consistent machining accuracy?
The BM160 features a rigid column and base structure that minimizes deflection during cutting, a precision-ground spindle for accurate rotation, and fine-adjustment feed controls for controlled material removal. These design elements work together to deliver straight, round cylinder bores and flat, smooth deck surfaces with repeatable accuracy.
5 Is the BM160 suitable for small to medium engine machine shops?
Yes. The BM160 is specifically sized and priced for small to medium engine rebuilding shops. Its compact footprint fits into workshops with limited space, its dual-function design provides excellent value, and its straightforward operation makes professional-grade boring and milling accessible to shops that do not need a large, production-scale machining center.
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.
